Abstract: Provided is a support structure and a method for manufacture thereof. The support structure, in one aspect, includes first and second expanded metal structural pillars positioned within the ground by a distance (d1), the first and second expanded metal structural pillars comprising a metal that has expanded in response to hydrolysis. In at least one other aspect, the support structure includes one or more beams spanning the first and second expanded metal structural pillars.

Abstract: In one embodiment, a method includes accessing a first document, accessing a plurality of second documents, calculating a relevance score for each of the plurality of second documents indicating a degree of relevance of the second document to the first document using an encoder of a machine-learning model, selecting a subset of the second documents based on their corresponding relevance scores, generating a target document by using the machine-learning model to process the subset of second documents and their corresponding relevance scores, and updating parameters of the machine-learning model based on a comparison between the first document and the generated target document.

Abstract: A system comprising a tubing encased conductor (TEC), a transformer inductively coupled to the TEC, and a wireless downhole device coupled to the transformer. The wireless downhole device may include a transceiver configured to receive and/or transmit, from the transformer, a digital signal encoded in a variable current in the TEC. The digital signal may correspond to a command. In some aspects, the wireless downhole device may be powered via the transformer, a battery, or a turbine.
