Temsah

Temsah Oil and Gas Field Profile

Location

The Temsah Oil and Gas Field is located offshore in the Nile Delta, Egypt, specifically north-northwest of Port Said. The exact coordinates are 31.618, 32.382 (WGS 84).

Operator and Ownership

The field is operated by Petrobel, a joint venture between BP and Eni S.P.A., with each company holding a 50% stake.

Discovery and Production

• The field was discovered in 1981.
• The Final Investment Decision (FID) year is not specified, but production started in 1999.

Production and Reserves

• Production Volume: The field has been producing gas since 1999, with a reported annual gas production of 868.19 million cubic meters in 2002.
• Reserves:
  • Estimated recoverable reserves are approximately 391.5 million barrels of oil equivalent (boe).
  • Gas reserves are estimated at 66,543.96 million cubic meters (recoverable) and 127,424.61 million cubic meters (Estimated Ultimate Recovery - EUR).

Geology and Structure

• The field is part of the Nile Delta basin, a hydrocarbon-rich province with reservoirs ranging from Plio-Pleistocene to Early Cretaceous ages.
• The Temsah field is characterized by a structure dissected by strike-slip faults trending NW-SE, resulting in horst, graben, and step fault structures. These faults control the hydrocarbon accumulations.
• The main reservoirs are within the Miocene formations, specifically the Wakar Formation, which is unconformably underlain by the Sidi Salem Formation and overlies the Rosetta evaporite.

Infrastructure

• The gas produced from the Temsah field is sent to the onshore El Gamil Gas Processing Plant for treatment.
• The field includes several platforms, with significant infrastructure developments:
  • The original platform was destroyed by a fire in 2004 and has since been replaced.
  • The Temsah pipeline end manifold (PLEM) is connected to four pipelines ranging from 14 to 32 inches in diameter and is situated in deep water.
  • Contractors involved in the development include Tecon, Petrojet Marine, Seaway Heavy Lifting, TDW, Saipem, and Micoperi for various aspects such as platform design, installation, and subsea operations.

History

• 1998: Amoco (now part of BP) and Eni signed a long-term natural gas sales agreement for the Temsah natural gas field.
• 2000: First gas production began.
• 2004: The original platform was destroyed by a fire.
• 2010: A new PLEM was connected.

Additional Context

• The Temsah field is part of a larger gas province in the Nile Delta and Mediterranean Sea, which has seen significant exploration and production activities since the 1960s. This region is known for its Pliocene age reservoirs and deeper structural closures that remain largely untapped.
