Ophir Gets Positive Results from Tanzania Gas Well

Ophir Energy has received positive results from its Ngisi drilling programme, Block 4 Tanzania and has upgraded recoverable resource across the Chewa-Pweza-Ngisi hub in Block 4 to 4.5 TCF. 

Ngisi-1 was drilled approx. 5km to the North East of the Chewa-1 well. The well was designed to appraise the Chewa gas discovery drilled in 2010 and to penetrate the Ngisi exploration prospect.

On completion of the initial well, two sidetracks were undertaken to further delineate both Chewa and Ngisi. Gas pay was encountered in the Ngisi prospect within a high net to gross reservoir interval.

The penetrations into the Chewa reservoir also encountered gas pay as prognosed and confirmed widespread, excellent reservoir characteristics. As a result, these wells have increased the mean recoverable resource of the Chewa-Pweza-Ngisi hub from 3.7 TCF to 4.5 TCF. 

Ophir holds 40% of Blocks 1, 3 and 4 while BG Group operates with 60% share.
