VAALCO Energy, Inc. says that the North Tchibala 1-H well, the first development well drilled by VAALCO in the North Tchibala field, was brought online at a rate slightly in excess of 3,000 gross barrels of oil per day (approximately 750 barrels per day net revenue interest to VAALCO). The well was drilled to a measured depth of approximately 11,160 feet, targeting the undeveloped Dentale reservoir. The Dentale formation is productive in fields onshore Gabon, but this well represents the first Dentale production for the industry from that horizon in the offshore waters of Gabon.
The North Tchibala 1-H well was initially brought on production utilizing an electrical submersible pump (ESP), but was subsequently allowed to produce naturally. The well is not producing any formation water or hydrogen sulfide (H2S) and has a strong flowing tubing pressure in excess of 1,000 PSI. VAALCO plans to continue to produce the well without artificial lift while monitoring surface and downhole pressures.
