DENIZ "King's Sea" Shah Deniz is translated as "King's Sea" The field lies between Mobil’s Oquz, Chevron ‘s Asheron and Exxon’s Nakhchiuan fields. The prospect is situated in the South Caspian Sea, offshore Azerbaijan, approximately 70 kilometres south-east of Baku. It lies beneath water depths ranging from 50 metres in the north-west to 600 metres in the south-east. The contract area covers an area of approximately 860 square kilometres. RESERVES Reserve estimates range from 1.5 to 3 billion barrels of oil (250 to 500 million tonnes) and 50 to 100 billion cubic metres of gas. Developent of these reserves in 600 metres water depths require technology developed for the Northern North Sea and Gulf of Mexico. SEISMIC AREA

EXPLORATION Two exploration wells will be drilled to fulfil the drilling obligation of the PSA. Starting the drilling programme , the well SDX-1 was spudded in July 1998 using the semisubmersible Dada Gorgud. Well SDX-1 is located 70 km south of Baku at location -E on the northeast flank of the structure in 135m water. Plans envisage drilling the top hole down to a depth of approximately 2500m before setting 13 3/8 in casing. This rig is not capable of drilling the lower sections of the Shah Deniz wells due to limitations with the derrick capacity and well control equipment. The newly re-built rig Shelf 5 will therefore continue the drilling to a depth of 6100m. Shelf 5 will then drill the second well by the third quarter of 1999 to a minimum depth of 5800m depending on the results of SDX-1. SHELF 5The Shelf 5 rebuild was carried out in the KMNF Shipyard, in less than 18 months involving the removal of 4000t of equipment. Water depth capability was increased from 280m to 700m , the variable deck load extended to 3200t, installing 9.6MW power and installing a 15,000psi BOP. FRONT END STUDIES In advance of the results of the first well, Shah Deniz is undertaking conceptual engineering studies now so as to be in a position ready to determine the most economical concept for the production of hydrocarbons. In March 1998, Caspian Resource Development, a joint venture of Amec process and Neergy, Fluor Daniel and JP Kenny as well as subcontractors Gipromorneftegas and the Caspian Drilling Company (SOCAR/Santa Fe) was awarded a contract for conceptual Engineering Services. It is envisaged that the field will be exploited in a phased development involving shallow water platforms with subsea systems in deeper waters tied back to the platforms. |
