Petrobras confirms Colombia gas discovery

Petrobras International Braspetro BV (PIB-COL) has confirmed what it calls a significant gas discovery offshore Colombia after analyzing data from the Sirius-2 well in block GUA-OFF-0, 77 km off Santa Marta in 803 m of water.

Natural gas production could begin within 3 years after receiving all environmental licenses and if the commercial viability of the discovery is confirmed, expected by 2027, the company said in a release Dec. 5.

Sirius-2 was spudded on June 19, 2024. Well results confirmed over 6 tcf in place, possibly increasing Colombia's current reserves by 200%, Petrobras said. 

Petrobras will begin gathering oceanic metadata as a part of the discovery's production development project. The data, combined with environmental information about the bottom of the sea, bathymetry, and geotechnical-geophysical information, will help inform decisions about installation of a natural gas pipeline that will carry gas from the field to the gas treatment unit onshore, as well as for installation of subsea production systems.

The consortium is expected to invest $1.2 billion in the project's exploratory phase and another $2.9 billion in the production development phase. 

Expected production is about 13 million cu m/d for 10 years through four producing wells in a subsea-to-shore design.

PIB-COL is operator of block GUA-OFF-0 (44.44%) with partner Ecopetrol (55.56%).
