The company’s Business Plan aims at incorporating resources in high reward projects concentrated in: onshore basins in Colombia (both foothills and foreland in Llanos basin, Middle and Upper Magdalena Valley, Putumayo and gas in Guajira, Sinú-San Jacinto and Lower Magdalena Valley), offshore Colombia (appraise and evaluate existing gas discoveries, as well as identify new hydrocarbons accumulations), and international areas such as offshore Brazil in pre-salt and post-salt Santos and Campos basins.
Exploration Activities in Colombia
In 2023, Ecopetrol and its subsidiaries drilled 26 exploration and appraisal wells in Colombia, out of which 21 were exploratory (A3/A2), three were appraisal (A1) wells, and two development (A0) wells with additional exploratory targets. As of December 31, 2023, eight wells were successful, nine were dry, and nine remained under technical evaluation. It should be noted that three of these 26 wells correspond to activity operated at the exclusive risk of partners. This drilling activity was concentrated in basins of interest around Colombia, including the Caribbean offshore, Llanos, the Lower, Middle and Upper Magdalena Valley and Sinú-San Jacinto.
The eight successful wells drilled by Ecopetrol and its partners in Colombia during 2023 were:
seven wells in Llanos Basin: In the department of Meta, the wells Saltador-1, Bisbita Centro-1 and Toritos-1 operated by Geopark Ltd. (Geopark) (50%) in association with Hocol (50%) in the LLA-123 block, and the wells Kimera-1 and Magnus-1 (B1) operated by Ecopetrol (55%) in association with Repsol (45%) in the CPO-9 block. In the department of Casanare the wells Zorzal-1 and Zorzal Este-1 operated by Geopark (50%) in association with Hocol (50%) in the block LLA-87.
one well in offshore Caribe Offshore, Glaucus-1, located in Block COL-5, and operated by Shell (50%) in association with Ecopetrol (50%). With this discovery, the gas province initially found with the Gorgon and Kronos wells has expanded. Shell and Ecopetrol are evaluating the potential of the discovered well. The gas discovery in the Glaucus-1 well confirmed the potential of the Southern Caribbean by adding more deepwater gas resources. Despite the successful results, the well was plugged and abandoned, in order to comply with Ministry of Mines and Energy regulations that require that wells that are not in production must be plugged to prevent loss of integrity.
In October 2023, the Farallones and Magangué exploration and production (E&P) contracts were signed. Ecopetrol holds 100% of the participation in both wells which are located in the Llanos Orientales foothills and in the Lower Magdalena Valley Basin respectively.

On June 4, 2021, Exxon Mobil Colombia signed a contract for the development of a PPII located near Ecopetrol’s PPII area, named Platero. On June 17, 2021, Exxon Mobil and Ecopetrol signed a consortium to jointly develop both PPIIs, in which Ecopetrol is the consortium operator.
On September 23, 2022, Ecopetrol filed a request for the suspension of the environmental obligations of Resolutions 00648 of March 25, 2022, and 01283 of June 10, 2022 before the National Authority of Environmental Licenses (ANLA for its acronym in Spanish), relating to the environmental license for the PPII Kalé. On September 29, 2022, the ANLA accepted Ecopetrol’s request and suspended such environmental obligations relating to the environmental license for PPII Kalé.
On November 4, 2022, in response to the request for suspension of the CEPIs filed on September 9, 2022, the ANH published Agreement 009, through which it was authorized to amend Clause 55 of the CEPIs, to allow for the suspension by mutual agreement of such contracts.
On December 28, 2022, the CEPI Kalé was formally amended to allow for its suspension by mutual agreement, as authorized by Agreement 009 of November 4, 2022, and was extended by Suspension Agreement No. 2 on October 4, 2023.
Ecopetrol is awaiting the outcome of bill for law 114, that intends to prohibit fracking in Colombia and is undergoing the legislative process in the Colombian Congress.
In addition, in connection with Ecopetrol’s unconventional resources strategy outside Colombia, in 2019, the company formed a joint venture (JV) with Occidental Petroleum Corp. (Occidental Petroleum) for the development of approximately 97,000 acres in the Midland Basin, within the Permian Basin, Texas, by which it acquired 49% of Rodeo Midland Basin LLC (Rodeo JV). As from January 1, 2022, the Rodeo JV agreement with the company and Occidental Petroleum was amended to provide Ecopetrol access to a larger production stake (75%), as well as to adjust its current carry obligations which will be paid in 2024.
On June 17, 2022, Ecopetrol Permian LLC (a subsidiary of Ecopetrol) signed a Joint Development Agreement (JDA) with certain Occidental Petroleum subsidiaries to carry out drilling and production programs from 2022 to 2027, in an area of approximately 21,000 acres located in Permian Basin. The agreement allowed Ecopetrol to expand its presence in the Permian with an approximately 49% interest stake of drilling and production programs in this area. Activity in Permian Basin started in December 2022 and started contributing to production during the second part of the first quarter of 2023.
On September 11, 2023, Ecopetrol announced certain adjustments to its 2040 Strategy, including that unconventional hydrocarbon exploration activities will not be pursued in Colombia, among other updates. See section 2040 Strategy: Energy That Transforms.
Marketing of Crude Oil and Natural Gas
In 2023, the company sold 1,005 mboed, out of which 472.4 mboed represented sales of fuels and petrochemicals (47%), 431.1 mboed represented sales of crude oil (43%), and 101.5 mboed sales of natural gas (10%).
Crude Oil Export Sales
In 2023, crude oil export sales totaled 430.0 and increased by 29.7 mboed compared to 2022, mainly due to higher production (+27 mboed). The company’s crude oil export sales are traded both in the spot and contract markets, primarily to refiners in Asia and the United States.
The Castilla blend is the main type of crude oil for export sales, with 279.3 mboed sold during 2023 (a 65% share of the crude oil basket) followed by the Apiay blend with 51.8 mboed (a 12% share of the crude oil basket), the Mares blend with 24.6 mboed (a 6% share of the crude oil basket) and the domestic crudes from Ecopetrol Permian LLC with 29 mboed (a 7% share of the crude oil basket).
The company places its exports in markets that provide the best value for its crudes. In 2023, Asia was the main destination, representing 54% of crude oil exports, followed by the United States with 38%. The expansion of the refining capacity in countries like China, as well as the fast recovery in crude demand of key refining hubs in Asia have supported the increase of crude oil flows sold by Colombia to that region. At the same time, the United States kept a strong position as a result of its economic reactivation.
In October 2023, the operation started in Ecopetrol US Trading LLC., in which Ecopetrol indirectly owns 100% of the share capital. This company sold 6.1 million barrels in its first three months of operation.
Crude Oil Purchase Contracts
The company has signed several crude oil purchase contracts with third parties and business partners. The company also purchased the country’s crude oil royalties from the ANH. These crudes are processed in the company’s refineries or exported.
During 2023, part of the company’s crude strategy was centered on increasing the purchase and subsequent commercialization of crude oil from third parties, which enables further optimization of the supply chain and margin capture.
Import of Diluents
In 2023, the company decreased the imports of diluent by 27% (9.7 mbod) compared to 2022, due to the use of domestically produced naphtha. Diluent is used to transport heavy crudes through the pipeline system.
Natural Gas Sales
The company sells natural gas to distribution companies through firm, interruptible and conditional contracts. These distributors supply natural gas to the residential market, as compressed natural gas for vehicles market and to large industrials in Colombia. The company also markets and sells natural gas directly to the industrial sector and to gas-fired power plants.
Joint Venture and Other Contractual Arrangements
The company conducts its exploration and production business through a variety of contractual arrangements with the Colombian Government or with third parties.
Association Contracts
The purpose of this type of contract, created by Decree 2310 of 1974, is the exploration of the areas covered by the contract, and the exploitation of hydrocarbons found in that area.
Incremental Production Contracts
The company enters into incremental production contracts to obtain additional hydrocarbon production beyond a base production curve that is established based on the proven reserves of a specific field or well.
Special Contracts
The company is a party to a joint venture for exploration and exploitation of La Cira-Infantas Area and of Teca-Cocorná Area.
These contracts between Ecopetrol and SierraCol Energy, formerly known as Occidental Andina LLC, which were executed on September 6, 2005, and June 24, 2014, respectively, have as their purpose, a joint collaboration between the parties with the goal of increasing the economic value of the La Cira-Infantas and the Teca-Corcorná fields, by means of hydrocarbon exploration and production activities, including, among others, an incremental production project to improve the recovery factor, process optimization, and exploratory activities.
Ecopetrol partially assigned its exploratory and production rights in the contracted areas to SierraCol Energy. Additionally, pursuant to these contracts, Ecopetrol provides financial resources and the preferential rights of use for the existing infrastructure in that zone and SierraCol Energy provides financial resources and the technical and operative experience in mature fields redevelopment projects and enhanced recovery technologies.
Ecopetrol is the operator under both joint ventures, and, on behalf of the parties, is responsible for the conduction, execution, and control, directly or via contractors, of the operational activities.
The La Cira-Infantas joint venture is divided into three phases. The first phase lasts 180 days, the second lasts 730 days, and the third phase lasts up to the date in which the field reaches its commercial viability.
The incremental production, after deduction of the royalties, is owned 52% by Ecopetrol and 48% by SierraCol Energy. The Teca-Cocorná joint venture is divided into two phases. The first phase lasts three years and may be extended for up to an additional year; the second term is 20 years and will be reduced by the term of any extensions of the first phase.
The basic production is 100% owned by Ecopetrol. The incremental production, after deduction of the royalties, is owned 60% by Ecopetrol and 40% by SierraCol Energy. These same percentages apply to the participation in the operational and direct expenses.
The National Hydrocarbons Agency (ANH) and its Contracts
The ANH was created by Decree Law 1760 of 2003 and was given the authority to administer all national hydrocarbon reserves under contracts executed from January 1, 2004. Pursuant to Decree Law 1760 of 2003, Empresa Colombiana de Petróleos, Ecopetrol, was split, and its organic structure was modified, to create two new entities: the Agencia Nacional de Hidrocarburos and the Sociedad Promotora de Energía de Colombia S.A.
E&P Contracts
The ANH only receives a percentage of oil revenues in two cases:
when the international oil prices rise beyond a specified price (high price fee), above which the ANH has a right to participate in a share of the increased revenues generated, or
in the case of recognition of production rights in an extended contractual phase (additional production share).
E&P contracts have three phases: an exploration period of up to six years counted from the effective date, which may be extended for two additional years, an evaluation period of two years, assuming reserves are discovered, to determine the commercial potential of the discovered reserves, and a production period, with respect to each production field, which may last for up to 24 years plus extensions, counted from the date in which the commercial viability of the corresponding field is declared.
ANH and Ecopetrol Agreements (Convenios)
Decree-Law 1760 of 2003 established that the rights over the production area and over the movable and immovable assets of all fields that were directly operated by Ecopetrol as of December 31, 2003, and all fields in which there was an association contract before said date will continue to belong to Ecopetrol.
Pursuant to Article 2 of Decree 2288 of 2004, which regulates Decree Law 1760 of 2003, Ecopetrol must execute an agreement with the ANH to regulate the exploration and exploitation terms and conditions of the relevant area, which was previously subject to an association contract.
Decree 2288 of 2004 also established that Ecopetrol would have to execute agreements with the ANH, covering fields directly operated by Ecopetrol. Under these agreements, the ANH recognizes the exclusive right of Ecopetrol to explore and exploit the hydrocarbons which are property of the Nation and might be obtained in the areas covered by the corresponding agreements. Ecopetrol’s rights shall last until resources are depleted or Ecopetrol returns such areas to the Nation through the ANH.
Transportation and Logistics
Transportation Activities
The transportation and logistics segment includes the transportation of crude oil, motor fuels, fuel oil, and other refined products including diesel, jet, and biofuels. The company conduct most of these activities through its wholly owned subsidiary Cenit Transporte y Logística de Hidrocarburos S.A.S. (Cenit) and its subsidiaries.
Transportation Capacity
The company’s main crude oil pipeline systems’ operating capacity was 1,489 thousand barrels per day in 2023. The company’s main multi-purpose pipeline transportation capacity included 549 thousand barrels per day in 2023.
Pipelines
As of December 31, 2023, the company, directly or indirectly with private partners, owned, operated and maintained an extensive network of crude oil and multi-purpose pipelines. These pipelines connect the company’s own and third-party production centers, import facilities and terminals to refineries, major distribution points, and export facilities in Colombia.
Cenit directly owns 46% of the total crude oil pipeline shipping capacity in Colombia. When aggregated with the crude oil pipelines in which Cenit owns an interest, Cenit owns 85% of the oil pipeline shipping capacity in Colombia. By December 31, 2023, the company’s network of crude oil and multi-purpose pipelines was approximately 9,040 kilometers in length. The transportation network consists of approximately 5,334 kilometers of main crude terminals and oil pipeline networks connecting various fields to the Barrancabermeja refinery and Cartagena Refinery, as well as to the company’s export facilities.
The company also owns 3,706 kilometers of multi-purpose pipelines for transportation of refined products from the Barrancabermeja and Cartagena refineries to major distribution points. Out of the approximately 5,334 kilometers of crude oil pipelines, owned by it, 3,121 kilometers of crude oil pipeline are wholly owned, and 2,212 kilometers of crude oil pipeline are owned through non-wholly owned subsidiaries.
As of December 31, 2023, the company owned 75 stations, 42 located in crude oil pipelines, 29 in refined products pipelines, two in crude oil ports and two in refined product ports.
As of December 31, 2023, the company had a nominal storage capacity associated with the transportation network of 16.4 million barrels of crude oil and 5.7 million barrels of refined products.
Pipeline Projects
Coveñas- Cartagena
This pipeline has a nominal capacity of 135,000 barrels per day and feeds the Cartagena Refinery with national crudes. As the demand for national crudes from the Cartagena Refinery continued to increase, Cenit identified a need to expand this system. In May 2020, Cenit approved the project to increase the system’s nominal capacity by 20,000 barrels per day to 155,000 barrels per day and has been in operation since November 2021.
Pozos Colorados Fuel Loading Dock
Seeking fuel supply flexibility in the area, the Fuel Loading Dock Project was developed in Pozos Colorados Terminal. As such, the scope of the project consists of enabling the facilities to deliver gasoline and load fuel trucks inside the station. The project was completed in December 2022 and is ready to use based on fuels demand in the area.
Apiay Fuel Loading Dock
Seeking fuel supply flexibility in the area, the Fuel Loading Dock Project was developed in Apiay. This asset allows alternative delivery of fuels by the dock in this Crude Oil Station. As such, the scope consists of enabling the receipt of fuels from the Poliandino pipeline to the fuel tank at the station in Apiay and the construction of the facilities required to load fuel trucks inside the station. The project was completed in November 2021 and is ready to use based on fuels demand in the area.
Ocensa Segment 3 Connection to Cenit Tanks in Coveñas
Seeking operational efficiencies for the Ocensa terminal in Coveñas, the Segment 3 Connection Project was developed. This connection consists of enabling direct deliveries from the entrance of the Ocensa pipeline to the tank system of the Cenit station in Coveñas. Previously, crude oil was received in Ocensa’s tanks in Coveñas and then transferred to Cenit’s tanks. The operation of this connection is governed by an agreement between Cenit and Ocensa, which defines the rate and operating conditions that should be in place with the project expected to result in additional income for Ocensa.
In 2021, stabilization of the system of the Coveñas Segment III Connection to Cenit Tanks - SEG3COV project was accomplished during the first days of January 2021. This connection has allowed direct delivery of barrels since the beginning of its operation, with a daily average in 2021 of 32,059 barrels per day, complying with the nomination of deliveries to customers and ensuring the stable condition of the delivery system by operators of Ocensa, Cenit, and Ecopetrol.
Vasconia Energy Recovery (RECVA)
In connection with Ecopetrol Group’s focus on energy efficiency, the company developed the Vasconia Energy Recovery (RECVA) project, which seeks to capture energy dissipated in the transportation process. Such energy is captured and converted from hydraulic principles into electrical energy to be used in the operation of the station, which reduces the consumption of energy supplied by the Regional Transmission Systems (Sistema de Transmisión Regional or STR for its acronym in Spanish).
Given that the Vasconia station operates 24 hours a day, an opportunity was identified to recover energy from the system, converting hydraulic energy (flow and pressure) into electrical energy through the installation of a hydraulic power recovery turbine (“HPRT”). In 2019, the HPRT was purchased, manufacturing was completed, and the engineering development was concluded.
In 2021, once the inconveniences derived from the pandemic were overcome, (i) the execution phase continued; (ii) the construction contract was awarded; and (iii) the civil, mechanical, electrical, and instrumentation works began. During that same year, pre-commissioning activities, including the selection of vendors for the commissioning stage, took place. In April 2022, the construction phase and commissioning stage were completed, and, in July 2022, HPRT operating tests and stabilization process, along with the environmental program (energy recovery and the reduction of CO2 emissions) were commenced.
Corrective maintenance in certain components and implementation of improvements to ensure a long and stable operation to meet the expected recovery efficiency were required once the operating tests were concluded and the HPRT started operations.
Operational Storage Program
The operational storage program’s objectives and scope includes ensuring a storage of more than one million barrels of refined products in five different stations. The program foresees the construction of more than 10 tanks distributed through four projects divided in this way: one tank of 260,000 barrels for Nafta and one tank of 323,000 barrels (under construction) for Biodiesel Extra (B2E) or Gasoline (GM) in Pozos Colorados Terminal; and two tanks of 100,000 barrels each in Sebastopol station and one tank of 62,000 barrels in Yumbo station (all this storage is for Biodiesel Extra (B2E) and Gasoline (GM)). The company is evaluating the construction of two tanks of 70,000 barrels each, to storage B2E and GM in Cartago Station and four new tanks in Medellín that in total has 254,000 barrels of capacity to storage Jet (JA1), Gasoline Extra (GE) and B2E.
The construction phase began in 2020 in Pozos Terminal and Sebastopol station and in 2021 in Yumbo station. According to the construction, startup phase and commissioning, the systems in Pozos Terminal, was completed in August 2022. Startup of the new tank at Yumbo took place in the first quarter of 2023, and the startup of the additional tank in Pozos Colorados Terminal will take place in 2024.
Andina Reliability Project
The aim of the Andina project is to increase reliability in the Salgar, Mansilla System through the replacement of 12 main pumps in four stations (Salgar, Guaduero, Villeta and Albán) to guarantee the supply of refined product to the interior of the country, mainly to the city of Bogotá and El Dorado International Airport.
Replacement of the La Valeria Single Point Mooring in Pozos Colorados Terminal.
The La Valeria Single Point Mooring (SPM) operating in the Pozos Colorados Maritime Terminal will need to be replaced in 2024, as the operational term specified in its safety certificate is coming to an end.
This will require, among other things procuring the design and construction of the SPM, transportation and delivery of materials, obtaining permits, registrations, and authorizations for the new unit and decommissioning of the current one, dismantling and final disposal of the current SPM; assembly, commissioning, and operational start-up of the new SPM; and (vi) stabilization of operations. Temporary reliability multibuoy system is in use since October 2023, and will serve as the operational continuity system during the replacement process.
Caño Sur Pipeline
The objective of this project is to enable the transportation of 100% of the production projection of the Caño Sur field owned by Ecopetrol, through a pipeline of approximately 20 kilometers long, between Caño Sur and the kilometer 30 of the Oleoducto de los Llanos Orientales - ODL transportation system. The producer could have benefits from an efficient transportation system, with a greater oil evacuation capacity of 44,000 bpd and with lower risks compared to the current transportation conditions. In 2023, the project completed the following milestones: (i) the basic engineering for this project was completed, (ii) the necessary environmental authorization was obtained, and (iii) the Ministry of Mines and Energy (Ministerio de Minas y Energía or “MME” for its acronym in Spanish) approved the new pipeline.
Electric Interconnection of the Estación el Porvenir (ENERGEPO)
Ocensa established a strategic framework to reduce emissions by 51% by 2030. In connection with such goal, Ocensa’s analyses indicate that the El Porvenir station is one of the plants with highest number of emissions, contributing 30% of the total tons of CO2e from Ocensa.
Based on this strategic plan, Ocensa is developing projects that aim to guarantee safe, reliable, and eco-efficient operations such as the 115 KV electrical connection between the El Porvenir station and the SIN, which project started during the first quarter of 2022.
The ENERGEPO project is subject to the completion of the Alcaraván expansion project, which consists of expanding the 230 KV and 115 KV electrical networks between San Antonio in Nobsa Boyacá and the new Alcaraván electrical substation in Yopal, by the Mining and Energy Planning Unit (Unidad de Planeación Minero-Energética or UPME for its acronym in Spanish).
In 2023, the company updated and defined the connection study and analysis regarding the importance of repowering the existing system with the execution of the Alcaraván project. In November 2023, UPME officially awarded this project (Alcaraván) to Alupar Colombia SAS.

Marketing of Transportation Services
Cenit and its subsidiaries’ main line of business is the crude oil pipeline transport (78% of revenues), followed by the refined products pipeline transport (15% of revenues) and ports and related services (7% of revenues). Both crude and refined product pipeline transport are regulated activities; crude oil pipeline transport services are regulated by the Ministry of Mines and Energy, while refined product pipeline transport services are regulated by the Energy and Gas Regulatory Commission (Comisión de Regulación de Energía y Gas or CREG by its acronym in Spanish).
Transportation contracts of crude oil may take several forms: ship or pay (payment for the availability of a fixed capacity in the system), ship and pay (payment for volumes actually transported), or spot contracts. The main users for the crude oil transportation business are Ecopetrol, Frontera Energy, Trafigura, Parex, Hocol, and Vitol, who collectively represented 77% of this business segment’s revenues in 2023. Transportation services for crude oil provided to Ecopetrol. represented 89% of this business segment’s crude oil transport revenues in 2023.
Cenit also transports refined products, and its main client is Ecopetrol., which accounted for 38% of refined products pipeline transport revenues in 2023, mainly due to the transport of naphtha, diesel, and gasoline. Cenit also has 27 other fuel wholesalers’ customers for whom it transports refined products. The most significant among them are Organización Terpel, Primax Colombia, Chevron Petroleum Company, Biocombustibles S.A.S., Terpel Exportaciones and Petrobras Colombia.
Deregulated businesses, such as ports and crude-loading facilities, represent a smaller portion of Cenit and its subsidiaries revenue (7% in 2023). Clients for these businesses include some of the same parties for which Cenit provides crude oil and refined products transportation services.
Refining and Petrochemicals
Refining
The company’s main refineries are the Barrancabermeja refinery, which directly owns and operates, and a refinery in the Free Trade Zone in Cartagena owned by Refinería de Cartagena S.A.S., a wholly owned subsidiary of Ecopetrol, who operates this refinery and two other minor refineries -Orito and Apiay-, but these are considered part of the upstream segment since most of the production is for self-consumption.
The company’s refineries produce a full range of refined products, including gasoline, diesel, jet fuel, LPG and heavy fuel oils, among others.
Barrancabermeja Refinery
The Barrancabermeja refinery produced approximately 42.01% of the fuels consumed in Colombia in 2023, according to internal calculations made by the company and Colombia’s fuel consumption as reported by the Ministry of Mines and Energy.
The company owns and operates four petrochemical plants and one paraffin and lube plant located within the Barrancabermeja refinery. In 2023, the company produced 43,320 tons of low-density polyethylene, an increase of 6% compared to the production of 40,864 tons in 2022. This increase was primarily due to the operational availability of the units associated with the polyethylene chain. The company produced 0,598 mboe of aromatics (benzene, toluene, xylene, orthoxylene, heavy aromatics, and cyclohexane), a 3.5% of increase as compared with the production of 0.578 mboe of aromatics in 2022, mainly as a result of an increase in exports to the international market accompanied by greater operational availability of the unit.
Cartagena Refinery
During 2023, the Cartagena Refinery imported butane in order to achieve the planned feed of the Butamer Unit and to increase the production of alkylate.
Esenttia S.A.
During 2023, Esenttia’s production totaled 441 thousand tons of petrochemical products.
