VAALCO Energy Inc. discovered multiple hydrocarbon-bearing sands in the South Tchibala 1HB-ST well from the Avouma platform in Etame field, offshore Gabon. The well is expected to be online this month, the company said in a June 2 statement.
The well was completed in the Dentale D1 sand interval (18 m net hydrocarbons), which is analogous to Deep Dentale producing field in North Tchibala with similar porosity and permeability, VAALCO added.
The Dentale D9 interval (15 m net hydrocarbons) was cased for future testing and completion. A thin section of Gamba sand was penetrated but is not economically viable to complete in this wellbore, the company said.
This well follows the Avouma 3H-ST development well completed in April and adds 2P reserves (OGJ Online, Apr. 26, 2022). Upon successful completion and first production, these reserves will add to VAALCO’s 1P reserves.
VAALCO is operator in Etame Marin block (63.6%) with partners Addax Petroleum Co. (33.9%) and PetroEnergy Resources Corp. (2.5%).
