One of the challenges confronting oil and gas operators — especially those working in areas with low fracture gradients or weak formations such as the Delaware, Anadarko and Permian Basins — is ...

Ultra-high performance concrete (UHPC) is an enhanced fibrous and cementitious concrete with high compressive strength (120–250 MPa) particle packing density (0.825–0.855, tensile strength (15–20 MPa) ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

A line of low-index, high-pressure compression springs consists of 144 slender parts packed with high-load capacities, rated to pressures of 300, 400, and 500 psi. The springs, made from 17-7PH ...

Concrete is an essential construction material that is used globally. Combining coring and rebound surveys provides the most efficient and cost-effective method of assessing in situ concrete strength, ...

Carefully controlled post-sintering deformation proves key to boosting strength while preserving ductility in Cu-SiC materials used for thermal and electrical ...
