RE: Lonny tweet15 Jan 2025 23:28
* The fact that Lonny is prepared to tweet positively about MOU-5 suggests to me that his parting from PRD was not the drama that some have implied, and that he still has a substantial shareholding. Interesting that the clueless OP thought that Lonny was still at PRD!
* MOU-3 is not a duster, it has clearly been stated that perforation has been successful - which means gas has come out of the holes blasted into the reservoir rock, but there are two issues.
* Firstly, there is a borehole (and possibly some of the adjoining reservoir) that is clogged with a mixture of drilling fluid, fine silt and water. The pressure exerted by this 1500m column is likely to be in the range of 2-3000psi, which is greater than the gas pressure, so preventing gas flow to surface. The first remedial action is swabbing, which we have been informally told will start in the next few days.
* If that is successful, we should have enough gas for CNG operations start up just from the sections already perforated.
* If unsuccessful, we move on to other remedial actions.
* If still unsuccessful, the second issue - shallow, high-pressure gas behind double casing - is then addressed.
* We have been told that Sandjet can penetrate two layers of casing. We know that the already-measured gas pressure will be much higher than the hydrostatic pressure of a shallow column of gunk, so it should blow naturally.
* An 11m thick highly-overpressured reservoir extending over 58km² will be more than enough to start up the CNG operation.
* So if the shallow gas is almost guaranteed, why not do that first? Because it would then be very difficult to do anything useful to release the gas lower down, even with a complex arrangement of plugs.
* I suspect the MOU-3 order of play is 1/ try to get lower-level gas flowing, investigate if it can be co-mingled with upper-level gas. 2/ If problems are anticipated comingling different pressures, only use lower-level gas from the existing borehole, and drill MOU-3a just to access shallow gas (quick & cheap). 3/ If no lower-level gas flow, perforate upper level and just use the top part of the current borehole for production.
