... is valid when fractures are uniformly distributed in space. However, the fracture distribution is commonly observed to have different scales. We propose to use our new double-beam ( db ) method to invert for spatially dependent fracture network information, in terms of fracture orientation, spacing...

... determined by an inversion, varying differential stress orientations and magnitudes to maximize slip and dilation tendency of the observed fractures. Only fault reactivation models in a strike-slip regime (σ 1 ~ 80°) predicted fracture orientations and mode consistent with observation. Proxy values...

... of subsurface stresses, they allow for the flow of gas and oil. However, when they are closed, as when the dominant stress is perpendicular to the fracture orientation, this flow is impeded. Optimal production is therefore obtained when well bores are drilled perpendicular to the path of the open fractures...

... a northwest-southeast or northeast-southwest strike. The orientations are generally aligned with the overall strike of the structure, and consistent with the expected maximum horizontal stress direction. Fracture orientation showed vertical and lateral variation in fracture strike across the field...

... that isolated fractures do not become imbibed spontaneously with fracture liquid, but their presence considerably increases the front displacement and width. Furthermore, isolated fracture orientation has negligible impact on front displacement and trapped wetting phase subsequent to drainage. Given...

... response to stimulation as well as the effectiveness of the treatment design. For instance, the orientation and magnitude of the maximum horizontal stress (SHmax) strongly affects the stimulated range of fracture orientations and in turn the geometry of the stimulated zone (i.e. localized versus...

... A and B). Both areas have the same high shale QI but have different fracture sets characteristics. Area A has a broad range of fractures orientation and Area B has a uniform orientation. A sensitivity analysis highlighted the importance of shear fractures for deriving stress variability. Fractures...

... Summary An integrated study of the well Zhao-104 and surrounding wide-azimuth 3D seismic volume within the shale gas reservoir in South China has been conducted with the objective of generating shale formation properties related to fracture orientation and intensity in the area and deriving...

Fractures observed within these three wells display similar characteristics and trends to those observed within the Cline in both horizontal and pilot wells across Sterling, Mitchell, and Coke counties. Similar fracture orientations have been observed...
