The Concession

The Emirate of Abu Dhabi, the largest of the seven Emirates of the United Arab Emirates, lies along the southern coast of the Arabian Gulf. Commercial quantities of oil in Abu Dhabi were first discovered offshore in September 1958, at the Umm Shaif oil field some 150 kilometers from the capital. Discovery of oil in commercial quantities onshore followed in August 1959 at Murban oil field (now known as Bab oil field), which lies in the desert some 100 kilometers to the southwest of the capital. Since that time numerous oil fields, large and small, have been discovered both onshore and offshore. JODCO's involvement in the petroleum industry in Abu Dhabi started in 1973 with its participation in ADMA Ltd.
Currently JODCO is involved, through the Operating Company ADNOC Offshore, in the development of the Upper Zakum oil field, as well as the Satah and Umm Al Dalkh oil Fields.

Upper Zakum oil field

Crude produced from the Upper Zakum oil field is gathered at the Zakum Central Complex through 3 satellite platforms. After being degassed, the oil is then pumped 60 kilometers to the Zirku Island Terminal for stabilization, storage and shipping. To maintain the reservoir pressure, water injection has been applied to the field since 1984. Currently, JODCO and its partners are engaged in development work using artificial islands with a view to increasing the production capacity of the field.

Satah oil field

Satah Crude is gathered at the Production Manifold Platform in the Satah oil field and flows directly under its own pressure via a 60 kilometer-long pipeline to Zirku Island, where it is treated and degassed prior to loading on tankers. Crestal gas injection has been introduced in 1988, and has been augmented by water injection since 1998. Gas injection is currently under temporary suspension due to well integrity issues, but JODCO and its partners are planning to restart it.

Umm Al Dalkh oil field

Crude oil from the Umm Al Dalk oil field is gathered at the Central Production Complex and then pumped via the Zakum Central Complex at the Upper Zakum oil field to Zirku Island. To maintain the reservoir pressure, water injection has been applied to the field since 1986. Some oil producing wells at the Umm Al Dalk oil field are equipped with electric subsea pumps (ESP).
