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 …
