Petrophysical properties define facies?
Are there special petrophysical property cut-offs that define facies or depositional environments. Co certain porosity cut-offs for instance relate to beach-sands while other indicate fluvial strate or turbidites. I would like to train my well logs on a regional scale, much like is done on denser datasets in single prospects and reservoirs. No we're working with GDE's (General Depositional Environments) interpreted by a host of different people from different companies that all have looked at the data. I want to end up with a consistent singular interpretation. (it doesn't need to be absolutely correct, bt does need to be consistent throughout the log dataset. I'm working in Petrel btw...
Hope this is clear...
thanks
