Abstract
A method includes identifying one or more stress regime types along at least a portion of a borehole, where the stress regime types are selected from a normal stress regime, a thrust stress regime and a strike-slip stress regime, and selecting reservoir access locations along the borehole based on the type of stress regime identified along the borehole.
Claims20
A method, comprising:
- identifying one or more stress regime types along at least a portion of a borehole, where the stress regime types are selected from a normal stress regime, a thrust stress regime and a strike-slip stress regime;
- and
- selecting reservoir access locations along the borehole based on the type of stress regime identified along the borehole.
A method, comprising:
- collecting data characterizing a formation around at least a portion of a borehole;
- locating at least one localized normal stress regime based on the collected data;
- and
- altering a trajectory of the borehole to extend through the at least one located localized normal stress regime.

A method, comprising:
- calculating a differential stress along at least a portion of a borehole, where the differential stress is the difference between the magnitude of two principle stresses acting on the borehole, the principle stresses selected from vertical stress, minimum horizontal stress, and maximum horizontal stress;
- determining locations along the borehole having a relatively higher differential stress when compared with the remaining calculated differential stresses;
- and
- perforating the borehole at a reservoir access location selected from at least one of the locations.
