    Abstract: A downhole tool includes a compact heat source including an inner housing having thermal insulation. The compact heat source includes an electrically activated heat source disposed in the inner housing and configured to receive electrical energy to generate first thermal energy. Additionally, the compact heat source includes active metal exothermic materials disposed in the inner housing and configured to receive the first thermal energy from the electrically activated heat source to initiate a first exothermic reaction in the active metal exothermic materials that generates second thermal energy. Further, the compact heat source includes a thermite material disposed in the inner housing. The thermite material is configured to receive the second thermal energy from the first exothermic reaction and ignite a second exothermic reaction of the thermite material to generate third thermal energy. Additionally, the compact heat source is configured to output the third thermal energy out of the inner housing.

    Abstract: A method of making a degradable alloy includes adding one or more alloying products to an aluminum or aluminum alloy melt; dissolving the alloying products in the aluminum or aluminum alloy melt, thereby forming a degradable alloy melt; and solidifying the degradable alloy melt to form the degradable alloy. A method for manufacturing a product made of a degradable alloy includes adding one or more alloying products to an aluminum or aluminum alloy melt in a mould; dissolving the one or more alloying products in the aluminum or aluminum alloy melt to form a degradable alloy melt; and solidifying the degradable alloy melt to form the product. A method for manufacturing a product made of a degradable alloy includes placing powders of a base metal or a base alloy and powders of one or more alloying products in a mould; and pressing and sintering the powders to form the product.

    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: The present disclosure relates to a method. The method includes receiving, via one or more processors, colorimetric data corresponding to a portion or integrality of a surface of a field component. The method also includes determining, via the one or more processors, a color value associated with the surface. Further, the method includes retrieving, via the one or more processors, trend data indicating relationships between a plurality of color values and a plurality of conditions corresponding to the field component. Further still, the method includes determining, via the one or more processors, a condition of the plurality of conditions correspond to the field component based on the trend data and the color value. Even further, the method includes generating, via the one or more processors, a condition output based on the determined condition.
