BG Group and Ophir Energy have completed the Pweza-2 appraisal well on Block 4 offshore Tanzania. The well was drilled to the south and downdip of the original discovery well, the Pweza-1, to better understand the wider distribution and quality of the reservoir sands across the Pweza field.
The well intersected 20 meters of net pay with excellent reservoir quality which was confirmed to be in pressure communication with Pweza-1. This result has firmed up Ophir’s resource estimates for the Pweza field which stand at 1.7 Tcf of gross recoverable resource.
The Deepsea Metro I drillship has been moved to the Pweza-3 location to the southwest of the Pweza-2. The Pweza-3 is designed to further appraise the field, including the collection of cores and a drill stem test. These are to confirm reservoir deliverability from the cluster of Block 4 discoveries that will provide a second hub for the LNG development. These activities are expected to be complete in early-October.
Nick Cooper CEO of Ophir commented: “The Pweza-2 results have confirmed our expectations for recoverable resource estimates in the Pweza field and we look forward to Pweza-3 both further delineating the discovery and underpinning its commerciality with the planned flow-test.”
