surprised steamtables by such responses. unfounded unprofessional.

you probably mean modifying the product NMR to determine the type of fluid. at Hala not remember (but probably steamtables is), at Baker - MRExplorer, in Shlyuma - MRX (MR-Scanner). tverchane still behind, but developments on this subject they have.

Acceptable results (IMHO) seen on offshore wells in China (Bohai Bay). There just sravnivalilas well with rezultatm MRIL-Prime (D) and stationary measurements CMR (Enhanced Diffusion). steamtables Sxo but is determined solely by NMR: Later calibration was done on a core (boring corer). Despite the differences in the depth measurement, the correlation of individual layers steamtables was to r = 0.85:

If Sxo - water saturation is flushed zone, I think that the relationship with Sor will be good enough. The only thing to find the function will need data on Sor c core from the same field, or at least equivalent.

Is there a difference in the reaction CMR between oil, water and mud? I have not seen such an analysis, as far as I know CMR can show if the oil is very viscous. steamtables Besides, as I see it, if it was only Sxo we would determine the residual oil from the resistance, which I also never met.

Yes, agree that things are not so simple. Otherwise steamtables would have long used these tools. Just the thought arose that there must be a connection Sxo Sor. But most likely type of parameters and the mud reservoir type, lithology, and so on. Will influence so that even if the correlation for some well and will be found, it is likely to be not applicable to other wells.

CMR can perform measurements at different fixed frequencies. In this case, it is possible to separate the signal from the oil-gas FBI and capillary water. steamtables Nazyvaletsya this technique D-T2 mapping or MRF. I had such results only in the Jurassic North Sea. But our guys Shlyuma claimed that similar results were obtained for W Siberia (I think there was a speech about "grouse" Samotlor).

With high-viscosity oil did not work, but there are a few SPWLA publications attempts to use CMR in Canada (high viscosity oil in limestone). In the few "live" examples that met T2 signal from oil always falls in the region of bound water that is less than 40 ms. "Pulled" from there it was only possible on the results of measurements on stationary or MARAN CoreSpec
