Method for rockwell hardness testing of tubulars post wellbore installation

Devices and methods are described for evaluating tubulars installed in a wellbore, which permit detection of wellbore construction errors. Errors in the hardness or grade of the material installed, e.g., in critical wellbores, could potentially affect the integrity of the wellbore and lead to catastrophic effects with respect to well control, pipe connection failure while running casing down-hole, or pipe body failure due to buckling or axial/triaxial failure during stimulation and production. Once tubulars are installed, the devices and methods permit testing the hardness of the steel or other material forming the tubulars. Determining the hardness of the tubulars may provide assurances or indications that remedial action may be appropriate to secure the wellbore. The devices and methods can be implemented to deliver a down-hole Rockwell hardness test in connection with logging while drilling technologies, with wireline tools, or in connection with other deployment mechanisms.

APPARATUS FOR DETECTING CHEMICALS IN A SAMPLE

An apparatus for detecting one or more chemicals in a sample, the apparatus including: a scanning unit including a light source configured to scan the sample using a light beam having a linear-shaped illumination; a dispersive element configured to receive light from the sample and disperse the received light spatially in a parallel manner; a spatial light modulator configured to receive the dispersed light and select one or more wavelength bands of the dispersed light; and a detection unit including a one-dimensional array of detectors configured to receive the selected one or more wavelength bands and detect the one or more chemicals in the sample based on the selected one or more wavelength bands, each detector of the array of detectors being a photon detector having a detection surface having a dimension below 50 m, the dimension being in a direction of the linear-shaped illumination.

INDENTATION PLASTOMETY

A method of performing indentation plastometry is provided. The method includes steps of: providing a sample of a material and an indenter having a contact surface of a predetermined shape and size; forming a first indent having a first penetration depth within the sample by applying a load to press the contact surface of the indenter into the sample; measuring a first indent profile of the first indent; on the basis of the first indent profile, and the applied load to form the first indent, obtaining a preliminary measurement of a characteristic of the material; on the basis of the obtained preliminary measurement of the characteristic of the material, determining whether a second indent having a different, second penetration depth is required to obtain a more accurate measurement of the characteristic of the material, and when the second indent is required, determining a value for the second penetration depth; forming the second indent having the second penetration depth within the sample by applying a load to press the contact surface of the indenter into the sample; measuring a second indent profile of the second indent; and on the basis of the second indent profile, the applied load to form the second indent, obtaining the more accurate measurement of the characteristic of the material.

Battery Abuse System that Facilitates In-Situ X-Ray Imaging and Multi-Modal Measurements and Methods Thereof

Systems and methods that facilitate X-ray imaging of lithium-ion (Li-ion) batteries during mechanical, thermal, and/or electrical abuse are disclosed. In addition to facilitating X-ray imaging, the system also facilitates the simultaneous collection of thermal, electrical, force, and displacement data during the abuse-testing of Li-ion batteries. Materials that are within the field of view of X-ray imaging are highly transparent to X-rays. The system also contains a mechanical indentation apparatus that facilitates high force indentation, compression, or penetration tests of batteries to induce mechanical failure or thermal runaway within the Li-ion battery.
