The IP program will use its error minimization methods to ensure results are in agreement with core and petrophysical data.Complex lithology analysis. Interactive Petrophysics– A weighted-least-squares error minimization technique to evaluate formation lithology, porosity, and fluid saturations. Our Geoscientist team perform the following processing and interpretation: Finally, if there are sufficient financial stakes, new wells might be drilled, cores cut, various additional sample measurements made, and both conventional and special logs run to obtain other desired petrophysical information. The technical personnel working with these data have to review what data are available, their quality, and what additional data might be acquired from the existing wellbores and from preserved and unpreserved cores. Petrophysical data take many forms and, for many reservoirs, may not be as comprehensive as desired. An important consideration is the acquisition and handling of the various types of petrophysical data and, for each reservoir, the preparation of its unique petrophysical database. One key to arriving at an accurate petrophysical calculation is to obtain the same quantitative result with a variety of techniques. Some of the petrophysical calculations can be made in several ways. These calculations need to be made not only as overall calculations, but also so that the variation and distribution of these parameters are determined appropriately. To make accurate calculations of OOIP or OGIP and the various flow calculations, accurate foot-by-foot calculations reservoir parameters are necessary. as well as reservoir lithology determination, diagenetic descriptions both vertically and lareally, etc. For the development geoscientists (geologists, geophysicists, and geostatisticians), petrophysics means developing the detailed reservoir characteristics in terme of Porosity, Permeability, Water saturation, net pay, cut-offs etc.
In practical terms, petrophysics is used for two types of calculations: determination of original hydrocarbons in place and their distribution, and reservoir-engineering dynamic flow calculations.
