Paper presented at the SPE Unconventional Resources Conference, April 1–3, 2014
Paper Number: SPE-168976-MS
... Abstract Induced fracture complexity maximization, in addition to the primary hydraulic fracture, to improve the recovery efficiency or productivity of gas or liquids in unconventional reservoirs has been accepted and fully implemented by the industry. As a result, stimulation fluids...

... of the second option would be that the completion cost is maintained but would potentially reduce production as significantly less of the lateral itself is stimulated. The goal of the methodology detailed is to have all perforation clusters break down and accept their equal portion of the stimulation treatment...

Rate-transient analysis (modern decline analysis) techniques are also more rigorous and have been expanded and adapted to fit the uniqueness of shale gas production. Application of each method for shale gas is discussed, including methods and limitations. These two...

... a simulation study on the optimum wettability conditions for maximum gas-condensate well productivity enhancement. Most of the work in this area focuses on reversal of wetting conditions from liquid-wetting (contact angle of 0 degree) to gas-wetting (with contact angle around 150 degrees). On the experimental...
