In anisotropic materials Skempton's B parameter becomes a second order tensor. It is well established from laboratory experiments that the Skempton B tensor may deviate significantly from isotropy, which will influence the pore pressure response. The anisotropy of B in essence results from the aniso...

Borehole collapse during drilling operations in shale formations is a well-known and costly problem within the petroleum industry. Recently it has become evident that shales may also form sealing barriers around the casing, reducing the need for cement jobs on new wells, and reducing costs for plugg...

Sealing of new wells, and the increasing need of plug and abandonment (P&A) of old wells, has triggered research and development of new methods for saving time at this operation. Shale has proven to seal off the annulus in longer well sections; however, the detection and qualification of the sea...

Pore pressure reduction, caused by reservoir fluid production, will alter the stresses in the vicinity of a producer. These stress alterations affect the propagation of hydraulic fractures that originate e.g. during water or polymer injection into injector wells as part of enhanced oil recovery (EOR...
