Petrobras Announces Drilling of New Wells in Colombia with Capacity for 6 Trillion Cubic Feet. Understand the Positive Impacts of Drilling New Oil Wells.
Petrobras announced on March 12 the drilling of new wells in Colombia in a large gas reserve discovered and is also evaluating the possibility of export via LNG. The data was disclosed by Petrobras’ Exploration and Production Director, Sylvia Anjos. The discovery and drilling of new oil wells can ensure Colombia’s energy self-sufficiency for at least a decade and opens new perspectives for the company’s international expansion.
Drilling New Oil Wells Can Supply the Country for 10 Years
The drilling project for new wells in Colombia utilizes a subsea to shore system, eliminating the use of production platforms. According to Anjos, formation tests showed high productivity, reinforcing the reserve’s potential, estimated at 6 trillion cubic feet (TCF). According to the director, this dry gas, pure methane, is ready for consumption and can supply the country for at least 10 years.
Petrobras is already planning new wells in the region to expand the reserve and assess the best export options. Liquefied natural gas is one of the forms discussed by the company, but the main goal is to ensure an extra reserve and analyze economic feasibility. According to her, the state-owned company has already talked to Ecopetrol about possible partnerships to make exports viable. As Sylvia reports, the reserve has been increased, Petrobras obtained the license, and is now seeking new export methods.

Petrobras Confirms Good Productivity in Well in Colombia
On March 10, before planning the drilling of new wells in Colombia, the company announced that formation tests at the Sirius-2 well, discovered last year in deep waters, confirm good productivity. This well is located in the Guajira Basin, in the Caribbean Sea, 31 kilometers from the coast and 804 meters deep. The reservoir is located 76 kilometers from the city of Santa Marta.
According to a company statement, which plans the drilling of new oil wells, the formation test evaluated an interval of approximately 100 meters of reservoir. In addition to confirming good productivity, samples were collected that are characterized through laboratory analyses.
Petrobras operates in the export and production of oil and gas in Colombia through its subsidiary Petrobras International Braspetro B.V – Colombian Branch (PIB-COL), which operates in consortium with the neighboring country’s state oil company Ecopetrol.
Colombians hold 55.56% of the consortium, while Brazilians hold 44.44%. When the consortium announced the discovery in Colombia in August, it was named Uchuva. It was only later that it came to be called Sirius.
Petrobras Also Explores Neighboring Oil Well
In addition to this reserve, where Petrobras plans to drill new oil wells, the companies also explore the Sirius-1, a neighboring well that is in the same exploratory block. According to the company, the consortium will continue to evaluate the results obtained from drilling the Sirius-1 and Sirius-2 wells, as per planning and contractual forecasts with the National Hydrocarbons Agency (ANH), according to Petrobras.
The ANH, linked to the Ministry of Mines and Energy of Colombia, is the regulatory agency for the oil and gas sector in the country, similar to the role the National Agency of Petroleum, Natural Gas and Biofuels (ANP) plays in Brazil.
According to the state-owned company in a statement, exploration in the offshore Guajira Basin block is aligned with the company’s long-term strategy, aiming to replenish oil and gas reserves through the exploration of new frontiers and partnerships.
