Imam from Indonesia Asks PERM: Is it necessary to determine T2 cut off to obtain permeability with NMR logging? If we don't have any NMR lab measurement data, how to adjust T2 cut off and justification for that? I am worried when I used default T2 cut off (let's say 33 ms for clastic). I got low correlation [...]
Mudar Asks PERM: Dear Sir/Madam, I am thinking that to simulate saturation properly in the reservoir by SHF via Pc, it is more relevant to use vertical plugs rather than horizontal as common, because water is sucked up by capillarity force mainly vertically. Please provide your view with explanation. Thanks Mudar Senior Petrophysicist Dr. Jonathan [...]
Castor from UAE Asks PERM: Hello, We will be drilling & coring with a “KPG (KCL-PHPA-Glycol) Low salinity” fluid, with a pH of 9.5-10. We will use D20 tracers to assess the core invasion of the fluid. However, from the literature I have read the following: “PHPA mud contamination strengthens the wettability of water-wet reservoir [...]
