Challenge: Determine the magnitude of in situ
stress for designing hydraulic fracturing of multiple intervals in the Antelope
Shale
Solution: Efficiently microfracture test
multiple intervals in a single run by deploying the MDT modular formation
dynamics tester to isolate the intervals between dual packers and inject fluid
to create and propagate small-scale hydraulic fractures
Results: Successfully placed hydraulic
fractures in the Antelope Shale on the basis of accurate in situ stress
measurements obtained by conducting multiple microfractures with the MDT tester
in a single run
