Modification of the Dubai Petroleum Co. (DPC) Fateh Field central production facility has reduced wellhead pressures about 10% field-wide, resulting in increased oil production and incremental reserve addition. The facility reconfiguration has reduced operating and maintenance problems experienced with separators and inlet piping, while improving oil recovery.
A key challenge of the Reconfiguration Project was to devise a separation scheme which redistributed fluid between vessels, and an installation method which utilized existing equipment to the greatest extent possible, eliminated downtime during facility modifications, and minimized investment.
Several reconfiguration options were identified and evaluated. The evaluation combined computer simulation results of surface gathering and separation facilities with modelling efforts of the primary Fateh reservoirs. The preferred reconfiguration option was justified on the basis of increased oil uplift associated with the wellhead pressure reduction. The project was successfully completed in mid-January 1994.
This paper describes methods used to evaluate the identified options, project planning, and project implementation. Predicted and actual results are given, and key project execution steps are described.
The Fateh Facility Reconfiguration Project evolved from studies of the Fateh Field central separation facilities beginning in early 1992. The studies identified opportunities to optimize separation and produced fluid handling.
Increasing water cut prompted significant additions and modifications to DPC central separation and processing facilities in the late 1980's and early 1990's. Included among these changes were the addition of two three-phase high pressure (HP) separators and water disposal systems in Fateh Field, and two three-phase HP separator conversions in the Southwest (SW) Fateh Field.
Despite these changes, it was recognized that a reconfiguration of the Fateh central separation and piping could significantly reduce pressure drop through the separator inlet piping, thereby reducing wellhead back pressure and increasing oil production.
