Ophir Successfully Tests Tanzania Gas Well

Ophir Energy has successfully completed the Pweza-3 appraisal well and flow test in Block 4, Tanzania. Ophir holds 40% of Blocks 1, 3 and 4. BG Group operates with 60%.

The Pweza-3 appraisal well was drilled approx. 2km north of the original Pweza discovery well and encountered 61m of gross pay on prognosis. A Drill Stem Test (DST) was performed which achieved flow-rate of 57mmscfd.

The implied unconstrained flow-rate is expected to be in excess of 150mmscfd. The DST has confirmed that the Tertiary reservoirs in Block 4 have similar excellent characteristics to those in Block 1.

The company said that result is expected to dramatically reduce the number of development wells required in Block 4, thereby simplifying the development plan and having a positive impact on the project's economics.

The Deepsea Metro I drillship will now move to Block 1 to drill the Mzia-3 appraisal well before drilling the high-impact Mlinzi Prospect in Block 7.
