C&P Presents: Converting P&A Candidates to P1 Reserves in Vertical Tight Gas Reservoirs Tapping a Treasure Chest of Stranded Gas

Natural gas can provide true energy independence for the country for the first time in history.  The good news is that ample supplies should be available for the near future.  The bad news is the vertical tight gas industry will be severely challenged by low prices for the near term future.  Vertical tight gas well recoveries in the past have been very poor, with 40 acre drainage recoveries in the 10% range vs the 70-80% expected range in virtually all US tight gas fields.  From extensive studies in multiple tight gas reservoirs the major damage mechanism driving the low recovery factors is most likely to be capillary phase trapping from the use of water based frac fluids.  Other possible causes such as gel damage, poor mechanical completion design, and low proppant volumes per foot of pay were evaluated and dismissed as major drivers.   A case will be presented that shows that higher oil based fluids can provide economic results if an operator can target candidates with high remaining mobile gas, maximize the effective producing frac lengths with fluids that do not create massive water block damage, and then use oil based refracs to eliminate drilling, casing, and cementing costs and economically increase the P1 PD and PUD reserve base
