Block 7

Block 7 is located to the north of the significant gas discoveries in blocks 1, 2, 3 and 4. It was awarded to Ophir Energy’s subsidiary Dominion Petroleum in January 2007. It is operated by the company with a 80 percent working interest. In November 2013, Dominion commenced drilling of the first well in Block 7. The Mlinzi Mbali-1 well is located approx. 210km east of Dar es Salaam in a water depth of approximately 2,600m. It was drilled by the Deepsea Metro I drillship. Pre-drill estimates showed that the reservoirs had a potential of containing up to 10TcF of natural gas. In January 2014, Ophir announced that drilling operations have been concluded and that no live hydrocarbons were confirmed.

In November 2014, Ophir announced that the second well drilled in the block did not yield moveable hydrocarbons either. According to the company, gas shows were seen in the primary target at the Mkuki-1 well but moveable hydrocarbons could not be confirmed.
