Abstract: A subterranean screen assembly comprises a base pipe with end connections to attach to a pipe string and a portion that is perforated or slotted; and a coated screen radially outwardly disposed of the base pipe. The coated screen comprises a screen substrate and a coating disposed on a surface of the screen substrate; the coating comprising an amorphous diamond like carbon doped with about 10 to about 30 atomic percent of silicon, about 10 to about 20 atomic percent of oxygen, or a combination comprising at least one of the foregoing dopants, or a polymer comprising a fluoropolymer, a silicone, or a combination comprising at least one of the foregoing.

Abstract: Downhole hanger systems and methods for hanging a first structure from a second structure in downhole environments are described. The systems include a first structure and a second structure, with the first structure disposed within the second structure. A composite joint is arranged on an outer surface of the first structure. The composite joint is formed of a material configured to be fused to both the first structure and the second structure and form a hanger joint having a shear strength of at least 2 ksi when the material is fused to the outer surface of the first structure and an inner surface of the second structure.

Abstract: A coating having a gradient composite structure, applied to a substrate, which may be a disposable tool. The gradient composite comprises a bonding component and an erosion and/or corrosion resistant component. When applied to a disposable tool, such as a ball and seat assembly in a downhole environment, the coating enhances the performance of disintegrable materials used in such tools. The coating may be configured to expire at the end of a selected duration, allowing the underlying material to disintegrate.
Abstract translation: 具有梯度复合结构的涂层，其施加到基底，其可以是一次性工具。 梯度复合材料包括粘合组分和耐腐蚀和/或耐腐蚀组分。 当在井下环境中应用于诸如球和座椅组件的一次性工具时，涂层增强了在这些工具中使用的可崩解材料的性能。 涂层可以被配置为在所选择的持续时间结束时期满，允许下层材料分解。
