NOV launches sour service drill pipe grades to ensure pipe integrity in challenging formations

NOV’s Grant Prideco business unit recently launched a line of drill pipe grades to help mitigate sour service failures related to sulfide stress cracking (SSC) in complex wells and acid gas-bearing formations. The new H2Shield grades were designed to provide strength and durability in harsh, sour drilling environments, delivering maximum mechanical performance without sacrificing H2S resistance. Offered as a smaller portfolio, the H2Shield line will simplify customers’ drill string selection, allowing them to select the right grade to achieve optimum performance in their sour service application.
