The Tennin gas field is located on the western end of the now relinquished East Delta Deep Block, north of the shallower North El Burg Offshore discovery.Under the exploration licence, the partners made three gas discoveries from six wells. The Taalab, Tennin and Tennin West wells discovered gas in the Pliocene El Wastani horizon. The exploration licence expired in 2007. Development licences were granted for the Tennin and Taalab areas in the same year. However, Talab was relinquished in 2013.
