Hyperdynamics Corporation today announced the Sabu-1 exploration well offshore Republic of Guinea was drilled to a total subsea depth of 2,224 meters, putting the well near the top of Cretaceous age sediments, and that the next string of 13-3/8 inch casing was successfully set.
Following retesting of the blowout preventer, the well was drilled to a depth of 2,304 meters. Drilling equipment problems were encountered, and drilling has been suspended while repairs are made. The delay is estimated to be approximately one week.
The Houston based company expects to test prospective upper Cretaceous sandstone reservoirs while it drills the Sabu-1 well to a total subsea depth of about 3,600 meters.
Ocean Endeavor completes seismic survey
Hyperdynamics also announced that the CGGVeritas Ocean Endeavor has completed acquisition of the 4,000-square-kilometer 3D seismic program in the deeper water portion of its concession offshore Guinea. Processing of the 3D data set is in progress, with the first preliminary time section results expected in March 2012.
Hyperdynamics operates the Guinea concession with a 77 percent participating interest, with the remaining 23 percent held by Aberdeen-based Dana Petroleum, a wholly owned subsidiary of the Korean National Oil Company. The well is operated through AGR, a well management company.
