Tight oil can be commercially recovered by horizontal well multistage fracturing. With the development of multistage fracturing tools, extended reach horizontal well could be a way to enhance unconventional tight oil economical efficiency. On the base of the study on Cardium formation, fracturing fluids were analyzed and slick water fracturing fluid was optimized. Frac port multistage fracturing string was studied and applied in pilot tests. Three extended reach horizontal wells with average 40 stages and 2954m horizontal length pilot tests were applied and studied. Comparison of well costs and production between extended reach horizontal wells and offset short horizontal wells were studied, extended horizontal reach wells get much more profits after six months producing when oil price above 101 CAD/bbl, and save 50% well construction costs and producing management costs.
