The BG led partnership in Tanzania has made one more gas discovery in the deepwater Rovuma Basin off the coast of Tanzania.
Taachui-1 ST1 well, drilled by the Deepsea Metro I drillship encountered gas in a single gross column of 289m within the targeted Cretaceous reservoir interval. Net pay totalled 155m. The well was drilled to a Total Depth of 4215mMD. Taachui-1 ST1 began as Taachui-1, drilled close to the western boundary of Block 1. The well was sidetracked for operational reasons to complete as the Observed reservoir properties are in-line with those encountered at Mzia, the other Cretaceous-aged discovery on Block 1. Estimates for the mean recoverable resource from the discovery are c.1.0 TCF. The size of the gas column is such that the discovery could extend into a second compartment to the west which has the potential to be of a similar size. An appraisal well will be required to confirm this upside and is under consideration by the JV partners.
BG Group operates Block 1with 60%, Ophir holds 20% , with Pavillion holding 20%. A Drill Stem Test will now be performed on the Taachui discovery with results expected before the end of June.
