Yes, I remember mud, just about.
Anyhow, reading the SDX competent persons report identified two issues for onshore Morocco in the rharb basin.
1. Local rock conditions can adversely interact with drilling mud to prevent logging and drilling. This has happened in the lnb 1 well in chariots new acreage and in the predator well mou 2. Predator indicated it was due to traces of natural potassium in certain clays that adversely interacted with drilling mud to form thick low viscosity mud . I believe Duncan has an eye for detail and will sample the lnb1 well cuttings to identify the issue and select the correct mud.
2. The SDX competent persons report noted that formation water samples were not available to calibrate the resistivity logs which identify hydrocarbons, so an assumption was used. Now chariot collected a huge data set offshore including 12 reservoir samples and sidewall cores, so it can recalibrate the onshore logs. In addition, chariot used seismic spectral decomposition very successfully offshore which can now be used onshore, hence the confidence of a 80 to 85% success rate.
As previously posted, the lnb 1 well encountered 300 meters of gross reservoir with seismic amplitude anomalies and flat spot above the drilled well, that group of clustered prospects were reported to have 26 bcf of reserves, however I believe that was based in 10 meters of reservoir, so if 300 gross meters have a net to gross of 60% , expect 180 net meters, which incidentally is close to the 150 meters encountered in an anchois 2. Now look at the seismic profiles in the chariot presentation showing anchois and guefrette side by side, very similar seismic profiles. We know that the average flow rate onshore rharb basin is 1.1 mmcf per day per meter, so for net reservoirs of 150 to 180 meters gives a daily flow rate of 165 to 198 mmcf per day, at a gas price of $10 to $12 mcf, very nice indeed.
The good old boys in Texas would call that a Barn Burner.
