Find out why we are SUPERIOR Reports ARTIFICIAL LIFT TECHNOLOGY 80 | COVER STORY Horizontal wells in ultratight oil formations are characterized by high initial production rates. But low matrix permeabilities mean they also tend to have reservoir recovery factors as low as 5-10 percent. Given the size of the resource base, a large prize is available to those who can find ways to increase recovery. One modeling study in the Bakken Shale demonstrates that injecting immiscible and miscible gas can be an effective means to increase oil recovery rates. by B.
