This course will teach you how to evaluate reservoirs and quickly identify flawed results. Robust, minimum error reserves are achieved by a logical, systematic integration of all relevant data. Interpretation is cost-effective compared with data acquisition or development mistakes and essential for the complex reservoirs and marginal fields being re-evaluated today. Systematic Integration will often replace the need to run expensive logs and explain apparent data conflicts. It provides the right answer faster, minimizes uncertainty and strengthens your position as an operator. By contrast stand-alone log analysis often results in bad economic decisions and bad personal reputations.
This course demonstrates through an experienced consultant how robust answers are achieved by the integration of diverse data. Basic economic questions are addressed head-on by a disciplined, logical process which optimizes the interpretation of Porosity, Permeability, Saturation, Net pay, and Fluid Contacts - the basis of Reserves. Low-Contrast-Low-Resistively pay, clastics and carbonates are evaluated by simple integration techniques which surpass stand-alone log analysis. LWD, wire line, NMR, image logs, routine & special core and MDTs are brought innovatively together to interpret difficult exploration wells, increase reserves and improve reservoir simulation. The Seismic Petrophysics work flow to project results into the geo.model is reviewed. This course is a condensed packet of powerful integration techniques. It continues to evolve through natural selection over 17years of presentations and mainstream consulting. Its manual is a comprehensive and lasting benefit to the novice and experienced student alike. Integrated Petrophysics first public, mainstream petrophysics integration course and remains THE BENCHMARK PETROPHYSICS COURSE TODAY.
