Ophir Reports Gas Discovery at Mkizi-1 Well

Ophir Energy plc (Ophir or the Company) announced the successful results of the Mkizi-1 well in Block 1, off Tanzania which has resulted in a new gas discovery. Ophir holds 40 percent of Blocks 1, 3 and 4. BG Group operates with 60 percent.

Successful Mkizi-1 well

The Mkizi-1 well was drilled by the Deepsea Metro I (UDW drillship) and was located in 4,268 feet (1,301 meters) water depth, between the Mzia and Jodari discoveries in Block 1. The well encountered gas pay in three reservoir intervals within a Tertiary aged stacked channel complex. Total net pay was 108 feet (33 meters) and reservoir quality was high with all three intervals exhibiting excellent porosities and permeabilities. Estimates for the mean recoverable resource from the discovery are in-line with Ophir's pre-drill expectations of 0.6 trillion cubic feet. 

The Deepsea Metro I will now move on to drill two appraisal wells, including a drill stem test (DST), on the Pweza discovery in Block 4. This will be the first DST on the series of Block 4 discoveries, following on from the successful tests in Block 1 on Mzia and Jodari.

Nick Cooper, CEO, commented:

"The successful Mkizi-1 well is our ninth discovery in Tanzania and continues our 100 percent strike rate in country, adding further resource to our existing discoveries in Block 1. Appraisal of Pweza will look to further underpin volumes in Block 4 which were upgraded with the recent success of the Ngisi drilling programme, whilst the DST is the final stage in firming up the commerciality of the resource across the Chewa-Pweza-Ngisi hub."
