Patent number: 12275889Abstract: A method of treating a fluid to reduce the level of H2S therein while inhibiting the deposition of scale on surfaces in contact with the fluid, comprising introducing into the fluid a triazine scavenger compound and a terpolymer. The fluid may be liquid or gas and may be petroleum, petroleum product, natural gas, liquefied petroleum gas or other type of oil fraction or refined oil. The triazine scavenger may be e.g. 1,3,5-tri(2-hydroxyethyl)-hexahydro-1,3,5-triazine. The terpolymer may comprise a carboxylate/sulphonate/non-ionic terpolymer. When added to a wellbore fluid, it is effective as a scavenger of H2S and also reduces the amount of scale deposition on a surface in contact with the fluid when the fluid comes into contact with or is mixed with a brine. In some aspects, the composition increases the proportion of precipitated solids held in suspension when the fluid is contacted with or mixed with a brine.Type: GrantFiled: January 20, 2022Date of Patent: April 15, 2025Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: James A.

Patent number: 12228004Abstract: A wellhead assembly with an external test port for testing a primary seal at an interface of a wellhead and a base. The assembly includes unique architecture with a secondary seal provided adjacent the primary. In this manner, testing of the primary seal from an external location may proceed without concern over a false indication of primary seal failure. That is, for circumstances where a more interior side of the seal fails under pressure testing even though an outer face of the seal might remain in sealing engagement, the secondary seal would ensure that the outer sealing engagement is detected. As a result, a practical manner of testing the wellhead seal from an external location without the need of plugging the wellbore is provided.Type: GrantFiled: December 15, 2020Date of Patent: February 18, 2025Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Edward Ganzinotti, III, Craig Cotton, Pheng Aun Soh, Juan Gonzalez
