Abstract: A system may include a substrate having a tensile strength of at least 10,000 PSI at an ambient temperature. The system may also include a carbon rich layer deposited on the substrate, wherein the carbon rich layer comprises at least one of a carbide, a nitride, a boride, a silicide, an oxide, a sulfide, or a transition-metal or non-metal ceramic-forming element, wherein the carbon rich layer comprises a carbon content including sp2 carbon and sp3 carbon, wherein the carbon content has greater than 40% sp3 carbon, a sp2/sp3 ratio of the carbon content is less than 1.5, or both. The carbon-rich layer is designed to reduce or prevent the formation of adherent scales on flow system surfaces used in well production, fluid injection or gas sequestration, and includes electrically-actuated downhole components having dynamic sliding surfaces.

Abstract: A fluid system component can include a body that includes a multidimensional shape defined in orthogonal directions and layers stacked along one of the orthogonal directions, where at least one of the layers includes polymeric material and graphene nanoplatelets formed in situ from the polymeric material, and where the graphene nanoplatelets increase stiffness of the polymeric material.

Abstract: Thermally induced graphene sensing circuitry and methods for producing circuits from such thermally induced circuits are presented in conjunction with applications to hydrocarbon exploration and production, and related subterranean activities. The thermally induced graphene circuity advantageously brings electrically interconnections otherwise absent on oilfield service tools, enabling components and tools to become smart.
