Though Tullow Oil has encountered hydrocarbons with its Okure-1 exploration probe drilled on the Deepwater Tano Block offshore Ghana to a total depth of 4,511m (14,800ft), the drill-bit encountered low net to gross oil-bearing reservoir in a secondary objective, having penetrated non-reservoir quality formations at the main objective levels below the so-called “TEN cluster”.
However, Tullow said that it recovered light 40Deg API oil from Okure-1. The next exploration well is Sapele-1, which is adjacent to the company’s Jubilee field.
