... of 9 to 16 years. Oil recovery factors, as a percentage of oil in place, range from 2.5 to 8 percent, leaving the vast majority of oil resources unrecovered. Shale oil EOR is in its infancy, with only 49 permitted projects involving a few hundred wells. 36 of these EOR projects are in the Eagle Ford...

... Abstract Horizontal drilling technology has become an economic reality, and the result has been a dramatic upsurge in the number of horizontal wells being drilled. Horizontal wells have proven to be cost effective in optimizing hydrocarbon recovery. Although the majority of wells were drilled...
