Shell Confirms Deepwater Oil Discovery Offshore French Guiana

London (ots/PRNewswire) -

As part of the Tullow-operated joint venture, Shell today
confirms an oil discovery in the Guyane Maritime permit approximately
150-kilometers offshore French Guiana.

The GM-ES-1 well is being drilled in a water depth of over 2,000
meters and to date has drilled to a depth of 5,711 meters. The well
has encountered over 70-meters of net oil pay in two objectives. The
joint venture plans to drill ahead to the planned target depth.

"We are pleased with the preliminary results of this first ever
deepwater well offshore French Guiana," said Dave Lawrence, Shells
executive vice president Exploration and Commercial. "We are early in
the evaluation, but the initial results are encouraging for this new
play. The joint venture will continue to drill ahead, evaluate the
well results, and determine next steps."

Shell acquired an initial equity interest of 33% in the joint
venture in 2009 and increased its equity interest to 45% in 2010,
subject to government approval. The joint venture is currently
operated by Tullow (27.5%) with additional equity interest held by
Total (25%) and Northpet (2.5%), a company owned 50% by Northern
Petroleum plc and 50% by Wessex Exploration plc.
