The first of these increments, Haradh GOSP-1 (gas-oil separation plant), went on stream in March 1996. The second increment, Haradh GOSP-2, was commissioned in April 2003. The third increment, Haradh GOSP-3, came on-stream in January 2006, five months ahead of schedule, and also added 140 million standard cubic feet per day of associated gas processing capacity.
Haradh GOSP-3 was the first plant in the Southern Area of company operations to have completely automated well control and monitoring, allowing remote operations.
The Haradh-III project benefited from successful integration of four technologies: multilateral, maximum reservoir contact (MRC) wells; Smart Well completions (using control valves for preventing premature water breakthrough); geosteering (for optimal placement of wells in the reservoir for maximum recovery); and the “intelligent field” concept, in which real-time sub-surface data transmissions enable continual monitoring of key reservoir indicators.
The integrated use of these four technologies slashed unit well development costs three-fold. If Haradh-III had been developed with conventional vertical wells, 280 producers would have been required, as opposed to the 32 MRCs which were used to develop the increment.
In 2011, multiphase pumps tested in Haradh and Shaybah fields proved their ability to revive dead or marginal wells and economically increase recovery. The Haradh multiphase pump was capable of reducing back pressure on a dead well to produce 3,000 bpd.
