Vaalco anticipates substantial gas output from well offshore Gabon
Following drilling, Vaalco Energy Inc has announced well results on the ETBNM-3 well and has mobilised the rig to a new slot on the SEENT platform to commence drilling operations on the ETSEM-3PH pilot hole and development well
The ETBNM-3 gas-supply well in the crestal portion of the North Tchibala structure from the Dentale D-15 reservoir is now placed for production. Reservoir properties were above pre-drill estimates, with strong porosity and permeability coupled with over 10 meters of net reservoir pay. The well will generate enough gas to cover field operations, liftings and power needs, replacing heavy dependency on high priced diesel.
The company is still evaluating the potential of the shallower pay intervals encountered in the D-9 and D-12 intervals, and has reported findings that indicate the presence of wet gas to light oil pay.
The ETSEM-3PH, on the other hand, has been planned as a pilot hole and subsequent horizontal Gamba producer near the crest of the central fault block of SE Etame. The pilot well will help to test the original field Oil Water Contact and potential of the underlying Dentale formation.
Following the pilot well, a horizontal development well is planned with a completion length of 300 meters within the Gamba sands.
George Maxwell, Vaalco’s Chief Executive Officer, said, “We continue to execute operationally across our diversified portfolio of assets. In Gabon, the newly successful gas well won’t add production or sales directly but will reduce costs associated with using higher priced diesel; this should improve field uptime and potentially add production uplift to existing wells over time. Our strategy remains unchanged with an ongoing focus on growing production, reserves and value for our shareholders.”
