Abstract: A method for obtaining hydrocarbon from a reservoir in a subterranean formation can include measuring a poromechanic pressure change due to lithostatic load sharing in the subterranean formation. The poromechanic pressure change can then be mapped to one or more locations within the subterranean formation. Once mapped, the method can identify one or more local pressure peaks in the poromechanic pressure change, wherein each of the one or more local pressure peaks are marked by a pressure escalation and subsequent pressure depletion. The method can then determine one or more regions within the reservoir exhibiting single phase hydrocarbon production.
