Encana has completed their frac jobs on the Weyerhaeuser 60H-1 and 60H-2. From what I understand, they used over 700,000 #'s of proppant per stage. They will be testing the limits of proppant that the TMS can withstand. I understand that the levels on the Ash wells will approach 1,000,000 #/stage. At some point, the relationship with the proppant volume and the initial rate will no longer be linear. A limit will be confirmed and beyond that, investment dollars are being wasted. With that said, I've updated my estimates utilizing the algorithm that factors in the past 14 completions and correlates it to feet of pay. The resulting predicted rates are outrageously high. As stated above, these frac jobs will likely define where the "proppant curve" rolls over and the resultant initial rate is no longer linear.
In that case, these "linear" predictions will end up being higher than actual. With more datapoints, the correlation will continue to tighten. The most likely impact of the higher proppant levels will be a flattening of the decline curve.
The next few weeks should provide some exciting results.
