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 is essential for the complex reservoirs and marginal fields being evaluated today. Systematic Integration often replaces the need to run expensive logs and explains 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 first by Quick Look Log Analysis then head-on by a disciplined, logical process which optimizes the interpretation of Porosity, Saturation, Permeability, Netpay, and Fluid Contacts - the basis of Reserves. Low-Contrast-Low-Resistivity pay, clastics and carbonates are evaluated by simple integration techniques which outperform log analysis with clear, direct results. LWD, wireline, NMR, image logs, routine & special core and MDTs are brought innovatively together to interpret difficult exploration wells, clarify Sw & permeability, increase reserves and improve reservoir simulation. The basic seismic "rock physics" work flow to project results into geo-models is then reviewed.
This course is a condensed packet of powerful integration techniques. It continuously evolves by natural selection over 20 years of presentations and mainstream consulting. It's manual provides comprehensive and lasting benefit to the novice and experienced student alike. Integrated Petrophysics.. was the first public, mainstream petrophysics integration course and remains THE BENCHMARK PETROPHYSICS COURSE TODAY. Do not be fooled by imitations!

The Instructor CV
Dr Mark Deakin is an experienced and innovative mainstream petrophysical consultant, author and enthusiastic tutor in petrophysics. He holds a Ph.D. in ‘Integrated Petrophysics’ from London's Imperial College, is an ex Amoco petrophysicist, and has 25 years experience, including 12 as a lecturer, independent consultant and Director of his consulting company. He has performed over 50 detailed reservoir studies, primarily in Southeast Asia’s difficult carbonates and stacked ‘low-contrast-pay’ reservoirs. Deakin chooses to work frequently in operations to keep abreast of new LWD, coring and wireline technology. His holistic approach brings each field's development uncertainties into sharp focus and then systematically reduces them by a strict, cost-benefit ranked plan of action. Innovative, appropriate integration and clear, practical recommendations result in improved simulation and increased reserves, at very low cost. Soon after his petrophysics PhD Deakin authored the first public petrophysical data integration course. He has continually evolved and chaired this and his Carbonate & Fracture course, publicly and in-house, for 20 years through OGCI, HOT and independently. Deakin is a long standing member of the SPWLA.
