Solid results from latest deepwater well offshore Tanzania

Offshore staff

LONDON – The drillship Deepsea Metro I has completed BG/Ophir’s latest appraisal well offshore Tanzania.

Pweza-2 was drilled 2 km (1.2 mi) south of the Pweza-1 gas discovery well in block 4. The downdip location was chosen to improve understanding of the distribution and quality of the reservoir sands across the field.

The well intersected 20 m (65.6 ft) of net pay, and confirmed pressure communication with Pweza-1. Ophir now assesses recoverable resources for Pweza at 1.7 tcf (49.02 bcm).

The drillship has moved 5 km (3.1 mi) to the west to spud the Pweza-3 well, which is scheduled to include a drillstem test. The partners aim to confirm reservoir deliverability from the cluster of block 4 discoveries that will provide a second hub for an LNG development onshore Tanzania.
