DHAHRAN, Saudi Arabia – Saudi Aramco has discovered three oil and two gas fields over the last year, according to the company’s annual report.
These included the deepwater oil field Al-Haryd in the Red Sea, which followed a significant gas discovery in the Shaur structure in this region the previous year.
Also in 2013, the company executed its first deepwater drillstem test at Duba-1, in the northern Red Sea, in a water depth of 2,127 ft (648 m). Results indicated tight reservoirs for potential future development.
As for offshore development programs, the shallow-water Manifa field off eastern Saudi Arabia entered production in April 2013, three months ahead of schedule, with output reaching 500,000 b/d of oil by July.
By the time it reaches its full potential at the end of 2014, Manifa will have the capacity to produce 900,000 b/d of Arabian heavy crude, along with 90 MMcf/d (2.5 MMcm/d) of gas and 65,000 b/d of condensate. It will also deliver feedstock to Jubail and Yanbu’.
Development involved construction of 41 km (25 mi) of causeways, 3 km (1.8 mi) of bridges, 27 drilling islands, 13 offshore platforms, 15 onshore drill sites, water supply wells, injection facilities, numerous pipelines, and a 420-MW heat and electricity plant. The man-made islands and the main and lateral causeways were constructed to house shallow-water wells, viewed as a more cost-effective option than offshore rigs.
Aside from being Aramco’s first project to combine onshore, offshore, and a causeway in a single project, Manifa established two world records, the company says. One was for drilling the deepest 6⅛-in. hole section to more than 37,000 ft (11,277 m), and the other for deploying a 7-in. liner with a length of more than 18,000 ft (5,486 m) to a depth of 26,000 ft (7,925 m).
Construction of the onshore Wasit gas plant is due to be completed this year. The facilities will process 2.66 bcf/d (75 MMcm/d) of non-associated offshore Khuff gas from the Arabiyah and Hasbah fields. Along with output from Karan, this will raise the Kingdom’s gas processing capacity by around 40%.
Under normal conditions, Wasit should supply 1.7 bcf/d (48 MMcm/d) of sales gas to the Master Gas System.
