Statoil ASA and ExxonMobil Corp. completed their first drillstem test in the Tanzania Block 2 resource. Two separate, equipment-constrained intervals flowed at a maximum of 66 MMcfd, confirming good reservoir quality and connectivity, according to Statoil.
The test was conducted in 2,400 m of water 80 km offshore the southern coast of Tanzania in the Zafarani reservoir. Statoil expects the production well rate to be higher than those obtained under the equipment constraints of the test. The company estimates the total Block 2 in-place volumes at 17-20 tcf (OGJ Online, Dec. 6, 2013).
Statoil operates the license on Block 2 on behalf of Tanzania Petroleum Development Corp. with 65% working interest. ExxonMobil owns the remaining 35% (OGJ Online, Mar. 31, 2010).
