Petrobras, Ecopetrol plan subsea-shore development for Sirius gas find offshore Colombia
Ecopetrol and Petrobras International Braspetro - Colombia Branch (PIB-COL) have confirmed a major gas discovery offshore northern Colombia.
The Sirius-2 well was drilled in 830 m water depth in the GUA-OFF-0 Block, 77 km from Santa Marta.
Analysis of the results suggest in-place volume of more than 6 Tcf. If confirmed, this could increase Colombia's gas reserves by 200%, the partners said.
PIB-COL (operator, 44.44%) and Ecopetrol (55.56%) now plan to acquire meta-oceanic data for the development. This and seabed, bathymetry, geotechnical and geophysical information will support construction of the offshore pipeline that will transport production from Sirius to an onshore gas treatment plant, and also installation of production systems on the sea floor.
The partners plan to drill four production wells exporting 13 MMcm/d over a 10-year period via a subsea-beach development.
Estimated costs for the exploratory phase are $1.2 billion and $2.9 billion for the development phase, with PIB-COL’s share included in Petrobras' Business Plan 2025-2029.
Work starts now on socio-environmental and licensing procedures to transport the gas to customers onshore.
