Ophir Energy reported a mixed bag of drilling results at two offshore Tanzania wells Friday, hitting a pay zone at a secondary target but drilling dry at two primary targets.
The Tende-1 well was drilled in the East Pande block by the Deepsea Metro I drillship to a total depth of 13,625 feet, targeting the Cretaceous-aged Tende prospect.
Although gas traces were encountered in the upper strata of the primary objective, wireline logs confirmed that no movable hydrocarbons were present in the prospect.
In the secondary Tikiti objective, the Tende-1 well encountered a gas bearing sandstone.
UK-based Ophir said it will evaluate the wider impact of this find as it integrates the well results into its understanding of the remaining prospects in the East Pande block.
Following the Tende-1 well, the Deepsea Metro I drillship moved to Block 7 where the Mkuki-1 well was drilled to a total depth of 10,511 feet.
The well targeted a Tertiary-aged stratigraphic prospect located in water depths of 5,406 feet.
Mkuki-1 encountered a “high quality sandstone sequence” but no hydrocarbons were present.
