Refracing to Maintain Production

The newest strategy to maintain production may be refracing producing wells instead of drilling new wells. Shale wells have a steep decline rate, and unconventional resource recovery averages only 4-8%. The strategy in the past 10 years has been to increase the number of frac stages, use more proppant, decrease well spacing and drill more wells. However, new wells cost more per barrel to produce, and may produce less oil. Halliburton’s ACTIVATE refracturing service pilot is stressing the value of refracing existing wells to go for the bypasses oil. Refracturing is a means to reconnect existing fractures to the wellbore and create new fractures to increase production in existing wells.
