Sure, there you are: FMI - fullbore formation microimager (microresistivity based) with interpretation: http://vader.joemonster.org/upload/rtp/14810830dd3eaa1FMI.jpg That was a nice image, but usually it isn't so simple: http://vader.joemonster.org/upload/rtp/14810842fe9d672FMI_2.jpg And as I said i...

So... There are couple different borehole imaging tool. Most popular are acoustic and electrical imaging tools. The rule is the same - you will get a centimeter scale image of the borehole wall. It is very usefull tool for fracture and breakouts identification. How to do that? You are looking for lo...

Well, yes and no. Dean-Stark is mainly for sandstone reservoirs but of course operators don't care - Dean-Stark is the most favored technique since fluid saturations, permeability and porosity are determined on the same sample. And it is cheap. So depite the fact that it is mainly for sandy reservoi...

That shall clarify everything: When shale volume is close to zero then total porosity overalys effective porosity (see attached - lower section) and core porosity match the log porosity. If shale volume is high then total porosity is higher than effective porosity due to clay bound water closed in c...

If core porosity was done with DEAN-STARK method your log porosity will only match the data in clean zones. In shaly zones Core porosity will be always somewhere between total and effective porosity. It is because drying clays during Dean-Stark lab process - there is always some Clay Bound Water tha...

From data like that it is possible to calculate porosity from density, and apparent permeability from porosity. Unfortunately your curves look like crap. Curves were at least blocked or something. If your data was correct, try this: Density porosity: PHID = (DENSlog - DENSMATRIX) / (DENSFLUID - DENS...
