Jim, FWIW I think as an oil man you could have worked this out yourself
The estimated target to achieve good representative reservoir contact has moved up from the original 40% to 60%. This target has moved as more well data has been collected during the flow back/clean out phase to date.
We also know that ~40% of the total injected has been recovered from the unblocked 75% of the horizontal section. Run that through the calculator and it shows the front 75% is at ~53% frack fluid recovery after some 30 days of sustained production post the coil tubing clean out.
(Leaving the complication of the initial 10% frack fluid recovery, pre clean out aside, as its origins are unknown, but fair to say more from the heel than the toe)
Recovery of frack fluid also follows a decline curve, so recovery will taper off over the last 7% in the front 75% of fractures. As this tapers off the oil flow will be tapering up, I would expect this to take be substantially complete in 14 to 28 days of renewed flow back/clean up, after which the oil rate will begin to trend down as is normal.
Where it gets complicated is the back 25% of newly unblocked horizontal, starts from almost zero and will required a similar time frame (44 to 58 days) to reach the 60% frack fluid recovery. In this same timeframe its oil flow will also be trending up as the frack fluid is recovered.
In time, and given the different production curve timings of the front and back sections of horizontal well. These two production curves will meet as the front curves down and the back curves up. That is the first key marker on decline curve analysis, and as fortune would have it is likely by the AGM and subsequent webinar on the 20th of March
