• Discovery holds between 5 and 12 trillion cubic feet of gas
  • Gas was struck at depth of 4,630 metres
  • Kosmos planning appraisal programme to delineate Tortue West discovery

The US’ Kosmos Energy has said its Tortue West discovery in Mauritania holds between 5 and 12 trillion cubic feet of gas, potentially making it the biggest gas discovery in offshore West Africa.

Currently, the largest confirmed gas discovery in the area is the Bosi gas field off the coast of Nigeria, which holds an estimated 5-7 trillion cubic feet of gas.

“Tortue… [is] without a doubt a world-class discovery and the first test of the outboard petroleum system in Mauritania,” said Brian Maxted, Kosmos’ chief exploration officer, on a conference call with investors on 4 May.

Kosmos’ latest discovery was initially announced in late April
