..., it is of paramount importance to predict horizontal in-situ stress changes during production and injection. Most often, it is assumed that a reservoir deforms uniaxially and the overburden stress is constant during production and injection. However, measured stress paths in the lab under these conditions have large...

... the weld as the weld tip propagates along the weld. When the source layer welds, salt flow from diapir pedestal into diapir stops, resulting in a hydrostatic salt pressure. This pressure is less than the overburden stress in sediments over the pedestal. In fact, the salt in the pedestal supports only part...

... Abstract We use a simple analytical model to estimate the stress field in and near density-driven, rising salt domes. We show that the salt pressure within such domes varies linearly along the dome but with a magnitude greater than the overburden stress. We also show that the salt dome...

A hydraulic fracture test conducted in a well drilled into a waterflooded portion of the reservoir showed that the effective minimum in-situ horizontal stress in the reservoir chalk is remarkably low (Teufel and Farrell, 1990).
