Depositional environment and its control on mechanical stratigraphy : an integrated study of process sedimentology, composition and geomechanics
Mechanical stratigraphy describes the mechanical properties associated with various strata in the subsurface and can be used to optimize hydraulic fracture completion designs, aid in targeting and placement of lateral wells, and determine wellbore stability. In unconventional plays, such as the Bakken Formation, where lateral wells and hydraulic fracturing are key to economic oil production, understanding the mechanical stratigraphy is crucial. This study examines the geologic controls on mechanical stratigraphy using quantitative measures of sedimentology, composition and geomechanical properties ...
