The past 10-years have been characterised by the increasing importance of hydrocarbon production from unconventional reservoirs, including tight sand and shale plays. The well in this case is a horizontal, tight-sand, gas-condensate producer. It is in one of Saudi’s largest unconventional reservoirs, and was completed using a uncemented, multistage, ball-activated sleeve system. The seven stages are separated by hydraulically activated dual packers. The first stage has one pressure-activated sleeve. The other six stages include three fracture sleeves each. The annulus volume between the sleeves contains short, swellable slip-on packers. The challenge was to assess the production contribution across all ports and then to confirm the effectiveness of the hydraulic fracturing operations.
