ئەمڕۆ دووشەممە ڕێکەوتی ٢٠١٨/١١/١٢، بە ئامادەبوونی مامۆستایانی فاکەڵتییەکەمان سیمینارێک پێشکەش کرا لە لایەن مامۆستای بەشی ئەندازیاری نەوت، بەڕێز(فواد حاتەم یوسفی) بە ناونیشانی: In Situ Stress and Rock mechanics Applied to Reservoir Processes (The first subject discussed in this seminar is the
magnitude of the least principal stress, S3, as obtained by hydraulic fracturing, specifically mini-frac (or micro-frac) tests done specifically for
the purpose of measuring stress. As One can determine the magnitude of the
least principal stress from a micro-frac, a very small-scale hydraulic fracture
induced only to measure stress at a particular depth, usually at a specific
depth through perforations in cemented casing. One could also determine the
least principal stress from a mini-frac, or the relatively small-scale frac
made at the beginning of a larger hydrofrac operation intended to stimulate
production in a low-permeability formation. |
