Course :: Rock Mechanics Testing: From Program Design to QC (RMT0515-01)

3 – 4 Oct 2016, London, UK

With a Special Introductory Cocktail Party on the Evening of Oct 2nd

COURSE DESCRIPTION

Laboratory testing of core material provides a direct measure of the rock mechanical parameters and playes a disproportionately large role in the oil and gas industry. In addition, the test data serve as a reference for the other acquisition efforts which rely on correlating the directly measured rock parameters against other parameters. Considering the high cost of acquiring, transportation and testing core, it is of paramount importance to utilize the latest rock mechanics knowledge and state of the art technologies to maximize the amount and accuracy of data acquired from drilled core. This very informative course aims in providing a complete understanding of the high value of cored samples for field development and engineering design and how they should be treated, preserved, and prepared until being tested in the lab. The course will comprehensively discuss the steps of rock mechanics testing from core visit and selection to designing a testing program, executing the program, quality control the procedure and analyzing-interpreting the results. Several case studies and test results on different conventional and unconventional reservoirs will be presented and discuss.
