<h1>Caño Limón Oil and Gas Project,Arauca,Colombia</h1>

<h2>Overview</h2>
<p>The Caño Limón Oil and Gas Project is an operating onshore conventional oil and gas project in Arauca,Colombia. Located in the Cravo Norte area near the Venezuelan border,it is operated by Sierracol Energy Arauca. Discovered in 1983,Caño Limón is one of Colombia’s most important oil discoveries. Ecopetrol estimates the reservoir held approximately 1.1 billion barrels at discovery,and the field helped Colombia regain net oil‑exporter status in 1986. The project remains active but is a mature onshore oil complex requiring ongoing field management and pipeline access to market.</p>

<h2>Location and Operating Area</h2>
<p>The project is onshore in Arauca,northeastern Colombia,close to the Venezuelan border. It lies within the Cravo Norte area and is associated with the wider Llanos Basin,a major Colombian oil province. SierraCol Energy operates the Caño Limón area under the Cravo Norte,Rondón,Chipirón,and Cosecha contracts. Crude is evacuated via the Caño Limón‑Coveñas pipeline,a 773 km system with a capacity of up to 210,000 bbl/d,operated by Cenit,an Ecopetrol subsidiary.</p>

<h2>Operator and Ownership</h2>
<p>The project is operated by Sierracol Energy Arauca. Ownership is held by SierraCol Energy (45%) and Ecopetrol SA (54%). Parent‑company interests are Ecopetrol SA and Carlyle Group. SierraCol Energy was formed after Carlyle acquired Occidental Petroleum’s onshore Colombian assets and describes Caño Limón as a world‑class reservoir and core asset. Ecopetrol’s involvement dates to the field’s discovery and remains central to the project’s long‑term operation.</p>

<h2>Development History</h2>
<p>Caño Limón was discovered in 1983. Initial production began in December 1985 from two wells at about 30,000 bbl/d,with full output following completion of the pipeline to the Caribbean coast. Ecopetrol states that Colombia started exporting oil again in 1986 because of this field. SierraCol Energy reports that the wider Caño Limón area has cumulative historical production exceeding 1.5 billion barrels. Development has been shaped by mature‑field operations rather than greenfield expansion.</p>

<h2>Production and Reserves</h2>
<p>Ecopetrol’s corporate history estimates the reservoir held about 1.1 billion barrels of oil at discovery. SierraCol Energy states that the Caño Limón area has cumulative historical production of more than 1.5 billion barrels. Current project‑level production figures are not available in public sources. As a mature field,production is influenced by depletion,water cut,workovers,and pipeline availability.</p>

<h2>Recent Developments</h2>
<p>The project is classified as operating in 2024 data. Pipeline security remains the most significant recent issue. Reuters reported that the Caño Limón‑Coveñas pipeline was forced to suspend pumping after explosive attacks in Arauca in July 2025,with 17 attacks by late July 2025 and 32 attacks in 2024. These disruptions directly affect crude evacuation from the field.</p>
