RE: Giant fields through the decades11 May 2024 12:25
I believe GRH is genuine in his beliefs that prd has potential to find giant gas/oil accumulations at guercif. I understand that he has a large databank of information not available to ordinary investors. As GRH has a tendency to be cryptic I have been trying to figure out where such giant and supergiant fields could be located in predators moroccon acreage.
Firstly, if we look at the independent technical report none of the prospects listed indicate giant gas field accumulations even at the p10 probability .
So where could these giant accumulations be.?
For a start we know that from a regional perspective we have a thermogenic and biogenic source rocks, there are multiple deep seated faults to help migrate the gas to reservoirs and that there are good top seal rocks which appear highly effective as sealing rocks and may provide stratigraphic closure for some Miocene reservoirs.
So that leaves reservoir thickness and structure as the key risks.
The Miocene reservoirs are typically 10 to 50 meters thick, still very valuable,if they flow test, but unlikely to be result in giant gas fields at geurcif, potentially in the wider licence area but would need a huge amount of drilling to confirm without 3 d seismic.
That leaves the Jurassic carbonates as another potential for large accumulations, while the carbonate thickness has been reported at circa 240 meters the ITR has indicated reservoir quality of carbonates at 20 to 50 meters, nice accumulations but not super giant. Even if the reservoir is 240 meters of good reservoir it gets to a few tcf , which is very nice but not a giant accumulation.
There has been mention of drilling mou 5 through the jurrasic and into the Triassic. However, the triassic reservoir would need to sourced from jurrassic source rocks above it. It’s possible migration could occur across faults if the source is juxtaposed across faults to the jurrasic reservoir, but this gets little support in the Itr and is certainly higher risk, but might be worth a look if drilling jurrasic anyhow.
Perhaps GRH might enlighten us a little more.
