Effective reservoir exploitation in tight-gas wells can be achieved by fracture-stimulating horizontal wells. A primary key to economic success when fracture stimulating horizontal wells is achieving the placement of propped fractures uniformly along the entire lateral section. This well completion strategy is becoming a more common method and is currently being used to effectively develop tight-gas reservoirs in northeast British Columbia, Canada.

This paper reviews different well completion and stimulation methods currently being applied in horizontal well stimulation in Northeast British Columbia, Canada. Specifically, the paper reviews horizontal well stimulation of the Montney formation that extends from northwestern Alberta into Northeastern British Columbia. Well construction and well completion strategy should be based on reservoir understanding and optimum stimulation design. This paper discusses a number of options for well construction and stimulation methods, including: packer isolation and frac sleeves, pump down bridge plugs and perforating guns, coiled tubing deployed bridge plugs and tubing conveyed perforating, and hydrajet perforating on CT with sand plug isolation. Evaluation and comparison of these different techniques include well construction, well completion including post-stimulation cleanouts, and post stimulation production analysis, including consideration of logistics, method reliability, and comparison of results.
