A client asked us this week about a variance in a PDP estimate. What we found is starting new analysis on shut ins. In the case of this operator, I found 100% of the delta was caused by offset frac related shut ins. Well after well right back on type curve. This also tells us:

That this operator, is drilling good wells, but they are pinned in their acreage. We calculated that 10% of potential production was shut in EVERY month for offset development. If they stay in development mode, we now understand the limitations of corporate cash flow.
