Numerical Investigation of the Osmatic Flow Impact on the Load Recovery and Early Well Performance
Abstract: The complexity of shale system coupled with the mystery of low fracturing fluid recovery has puzzled many researchers. Field reports from hydraulic fracturing operations performed on shale formation have highlighted the low recovery of the fracturing fluid. The fate of the hydraulic fracturing fluid is still controversial issue. However, literature has attributed the low load recovery to either trapping into the natural or created micro-fracture or imbibition to the matrix. …

Breathing prediction of fracture deviated wellbore through flooding mechanism
Abstract: Wellbore breathing is a common occurrence during drilling operations, but the down hole mechanism and how it manifests itself in surface and subsurface processes, is not well understood. It often result in a drilling fluid gain at surface and are misidentified as a kick, resulting in unneeded shut in periods and associated non-productive time (NPT). Further, misidentification of wellbore breathing as underbalance often results in increases in mud weight, which …
