Publication number: 20230279555Abstract: A coated structure may be formed with a hydrogen-resistant coating for use in a corrosive service environment. The structure may include a ferrous base metal with sufficient structural strength, despite being susceptible to hydrogen degradation in an uncoated state. A hydrogen-resistant coating is formed on the base metal without increasing a temperature of the base metal beyond a tempering temperature of the base metal. A preferred coating method is cold spraying. The cold spraying may be performed at sufficiently high pressures to achieve a low porosity without requiring a post-coating heat treatment that may otherwise reduce the strength of the base metal.Type: ApplicationFiled: March 2, 2022Publication date: September 7, 2023Applicant: Halliburton Energy Services, Inc.Inventors: Thanh Nam Vu, Arpana Singh, Michael Linley Fripp, Shashwat Shukla

Publication number: 20230280191Abstract: HIC-resistant materials may include sensors embedded within or otherwise coupled thereto for use in a hydrogen service environment. In an example, a diagnostic system includes a first sensor embedded within a structural metal for exposure to hydrogen for generating a signal response to both the hydrogen and one or more parameter. A second sensor is embedded within the structural metal for generating another signal response to the one or more parameter. A hydrogen-suppressing layer is provided to suppress any response of the second sensor to the hydrogen. A controller in communication with the first and second sensors distinguishes the signal response of the first sensor from the signal response of the second sensor to characterize the hydrogen and the one or more other parameter.Type: ApplicationFiled: March 2, 2022Publication date: September 7, 2023Applicant: Halliburton Energy Services, Inc.Inventors: Shashwat Shukla, Arpana Singh

Publication number: 20230082733Abstract: The present disclosure provides elastomer blends comprising mixtures of partially fluorinated elastomers, such as tetrafluoroethylene propylene elastomers (FEPM or TFEP) and fluorocarbon rubbers, such as vinylidene fluoride-based elastomers (FKM or FEP). The elastomer blends can be prepared using two-roll mills, internal mixers, or other mixing technique and can be molded into seals, gaskets, o-rings or other articles using extrusion, injection molding, compression molding or the like. The resultant elastomeric articles can provide good sealing performance, including at moderate or low temperatures, and exhibit good chemical compatibility and resistance when exposed to common wellbore environments. In some cases, the elastomer blends can provide performance characteristics previously only available from perfluorinated elastomers (FFKM), but without requiring the complex processing conditions associated with preparing perfluorinated elastomers.Type: ApplicationFiled: September 14, 2021Publication date: March 16, 2023Inventors: Sandeep Thatathil, Shashwat Shukla, Arpana Singh
