RE: RE: 15 bopd wells and worse. While I agree with the direction of your comments, I have a couple of modifying points:
Certainly right on the calculation of average, but it is heavily skewed by the production from new wells which begin in the 125 to 175 range. But where did you get your well count, I have a lower number?
Waterflood production gain is a two step forward one step back process. Your estimate on existing wells has to take account the ratio of injectors to producers. The 50-100% is the expectation for producers but you have to subtract the lost production of the injector. The ratio of injectors / producers is expected to be 1/3or4.
Example, four wells producing at 30 bopd, one converted loses 30, 3 increased at low estimate 50% adds 45, net gain 15 or about 12 %. High estimate, 3 increased at 100% adds 90, net gain 60 or 50%.
They have tried infilling the sections to increase the ratio of producers to injectors, but 8 proved too much and lowered initial production, they now see 6 as the ideal number; but it remains to be seen whether 1 injector can produce the higher lifts on 5 producers.
