Petrophysics Training & Consultant

1. Core Analysis Freebies Conventional (Routine) Core Analysis from full core or rotary sidewalls provide a platform for the calculation of many petrophysical parameters, for each plug, via inversion of the equation to solve for the equations least certain variable. is an extremely fruitful approach to petrophysics and leads to hard answers wherever the reservoir rock type (RRT) and This ideally the borehole type (BT) are similar. core data has far greater value than the conventional limited With this approach use of grain density, porosity and permeability. approach in formation evaluation opens up countless fast solutions to problems which were previously seen as unsolvable or requiring the acquistion of more expensive log Problems which were put in the “too hard”, “too expensive” or “too slow” basket. Moving to this data. Some of the freebies on offer include: rhoga, rhofa, npmxa, npfa, dtmxa, dtfa, Rwa, ma, BQva, na, T2cuta, BFVa, aa, porcut, swcut

2. The suffix “a” denotes the value is not a direct measurement but an apparent value from the equation from which it is derived. decided to use for the petrophysical training evaluation of the output in question, e.g. Sw, for the reservoir rock type (RRT) and the data available and must be used in the subsequent evaluation The equation is the equation the petrophysicist has
