MEM.
You make a good point regarding the drilling and test results, what if it’s ambiguous .
So let’s just analyse where the ambiguity may arise.
We know from the mou 1 well that the deeper reservoir horizon was over pressurised requiring a heavier mud weight which penetrated the reservoir and traditional rapid log analysis could not see gas near the well bore, but the drilling results showed high gas readings in the drilling mud. The mou 1 well has also identified a shallower gas horizon which was gas bearing and which was not immediately identified as gas bearing.
So what can be done to avoid a repeat of this situation at mou 2 well.
Firstly, well is being designed from the outset to cater for an overpressurised well, I expect this will include modifications to the logging tools to read deeper into the well bore.
As predator are also planning to flow test mou 1 well, on completion of drilling and logging of mou 2, they could suspend the well for testing and proceed to move the rig to mou1 well to prepare it for flow testing, complete the flow testing of mou 1 well and during this time have third party expert log analysts complete the analysis of mou2 well and then proceed to perforate and flow test the mou2 well.
In these circumstances, communication of the initial mou2 well results will be important and consideration should be given to holding back the well results till third party experts have completed their analysis of the well logs and flow testing can then be performed as appropriate.
At the end of the day we are ideally looking for a minimum of 10 mmcf per day and ideally 20 mmcf per day as that would satisfy the immediate local requirements and generate good cashflow for predator to finance follow on drilling.
