Weather forces change to offshore Gabon drilling sequence

Offshore staff

HOUSTON – VAALCO Energy (NYSE: EGY) and its partners have re-sequenced a drilling and workover program in the Etame Marin block offshore Gabon

Following positive results last month from the initial North Tchibala field development well, VAALCO had planned to mobilize the jackup Transocean Constellation II to the Avouma/South Tchibala field for workover operations to replace electrical submersible pumps on three existing development wells, two of which have been off production. 

However, adverse sea state conditions at the location of the SEENT platform prevented the relocation of the rig. Rather than wait for an improvement and incur the expense of idle/standby rig time, the partners have opted instead to drill and complete the North Tchibala 2-H well, in order to produce oil from the deeper Dentale D18-19 formation. 

Drilling operations are proceeding and the well is expected to reach a depth of around 16,000 ft (4,877 m). Thereafter the rig will be mobilized to the Avouma/South Tchibala platform for the workover campaign.
