US Classification:

7315202, 250256

Abstract:

A method and apparatus for determining a stress field in a subterranean formation include deploying a stress measurement tool on a tubular string, opening at least three fractures in three different radial directions in the subterranean formation, and closing the at least three fractures. The at least three fractures are reopened while measuring stress and strain conditions. From the reopening, a tangential stress component for each of the at least three fractures is determined. From the tangential stress components and radial directions of the at least three fractures, the stress field of the subterranean formation is determined.

Abstract:

Novel synthetic methods to produce layers or films and flakes of pristine graphene, heteroatom-doped graphene, nanoporous graphene or heteroatom-doped nanoporous graphene using specially designed molecular precursors at temperatures as low as 160 C. using a chemical vapor deposition (CVD) system. The methods enable the realization of graphene-based electronics and technologies due to the low-temperature synthesis, large-area coverage, and scalability of the CVD method by taking advantage of the precursors tendency to polymerize and fuse once on the catalytic metal substrates.

Abstract:

A method of testing mechanical properties of an earth formation can include disposing a probe in a wellbore, impacting the probe against a wall of the wellbore, and measuring a parameter related to at least one of a displacement, displacement rate, strain, and strain rate, of at least one of the probe and the formation. Another method can include disposing a probe and a known material in a wellbore, and after the disposing, penetrating the known material with the probe. Another method can include disposing a probe in a wellbore, measuring a displacement of the probe into a wall of the wellbore while measuring a load applied to the probe, and applying fluid pressure to the formation via the probe.

Abstract:

The present disclosure relates to identifying potential fracture treatment locations in a rock formation for oil and/or gas production based on production potential. One example method includes receiving internal imaging data of a core sample of a rock formation; generating a digital core sample model of the structure of the core sample based on the internal imaging data; analyzing the core sample model to determine the density distribution of a deposit in the core sample; and determining a production potential value from the density distribution of the deposit.
