South Pars / North Dome Gas-Condensate field
From Wikipedia, the free encyclopedia
The South Pars / North Dome Gas-Condensate field is a gas condensate field located in the Persian Gulf.
The field is the biggest gas field in the world, shared between Iran and Qatar. The South Pars Field is the name of northern part, which is located in Iranian waters and the North Dome is the name of southern part, which is located in Qatari waters.
Reserves have been estimated variously at 1900 billion cubic feet (53.8 billion cubic metres) gas in place and 56 Billion barrels of condensate, and at 1200 trillion cubic feet (34 trillion cubic meters).
The field consists of two independent gas-bearing formations, Kangan and Upper Dalan. Each formation is divided into two different reservoir layers, separated by impermeable barriers. Therefore, the field consists of four independent reservoir layers K1, K2, K3, and K4.
The estimates for the Iranian section are 500 Tcf (14 Tcm) of gas in place and around 325 Tcf ( 9.2 Tcm ) of recoverable gas; the estimates for the Qatari section are 950 TCF (27 trillion cu.m).
South Pars Field was discovered in 1990 by NIOC; North Dome was discovered in 1971.
Production started from the southern extension of the field, the North Dome in 1989, at daily gas production rate of 800mmscf/d.
Gas production started from South Pars field by commissioning the development phase 2 in December 2002 to produce 1bscf/d of wet gas. Gas from the South Pars field is sent to shore via pipeline, and processed at Assaluyeh.
