Taught by George B. Asquith, this course has been designed to benefit geologists, engineers and technical support professionals who are involved in oil and gas exploration and production in carbonate reservoirs. Part of the Winter Education Conference this course will take place Friday February 14, 2014 in Houston, Texas. For more details: http://www.aapg.org/education/wec/details.cfm?ID=106
At the conclusion of this course participants should be able to accomplish the following:
–Scan a well log to determine zones that potentially could be hydrocarbon productive.
–Examine pre-processed and calculated well log data and be able to answer the following questions.
1. What is the carbonate pore type or types?
2. Is the reservoir water-wet or oil-wet?
3. Is the reservoir hydrocarbon productive?
4. If hydrocarbon productive will the production be oil or gas? Do you expect a water-cut?
–Use a cross plot method to help verify the answers to the four questions.
–Once the above four questions are answered the participants should be able to determine a strategy to improve the calculations of the reservoir’s water and hydrocarbon saturation.
As the title states, this is a quick guide that concentrates on methods used to analyze carbonate reservoirs. It is an advanced course and assumes the course participants are already well informed about basic will logging principles.The course begins with a short review of the basic principles of carbonate well logging. Next are a series of lectures on the different carbonate pore types and the logging methods used to differentiate the various pore types and to determine their hydrocarbon productive potential. A flow chart is provided that will aid the participants’ understanding of the sequence used in analyzing carbonate reservoirs. At conclusion, seventeen problems will be presented that will be analyzed by the participants. In six of the problems, they will be required to do some of the calculations. They will then answer the four question outlined above for each of the seventeen problems. Next, they use a cross plot to help verify their pore type, wettability, and hydrocarbon productive potential conclusions determined in the seventeen problems.
