HOUSTON, Apr. 5 -- Artumas Group Inc., Calgary, expects its Msimbati-1X exploration well to become the second hydrocarbon discovery in the Mnazi Bay concession, Rovuma basin, in southern Tanzania.
The well, 2.5 km southeast of the Mnazi Bay-3 well site, went to TD 6,570 ft and penetrated the primary objective Middle Miocene sands (Msimbati Prospect) at 4,800 ft. These sands represent a high-amplitude fairway separate from Mnazi Bay gas field.
At 6,000 ft, the well encountered the classic Miocene/Oligocene sandstone formations of Mnazi Bay gas field, which the MB-2 and MB-3 wells appraised. Drillstem test results are expected in mid-April. The field was discovered in 1982 and began delivering gas in January through a 27-km pipeline to the 12-Mw Mtwara electric power station (OGJ Online, Sept. 27, 2006).
Artumas approved 60 line-km of 2D seismic surveys that will focus on highgrading a deeper exploration prospect for an Eocene/Cretaceous oil test on the Mwambo Prospect. The company expects to drill a well in the third quarter.
