Patent number: 11898415Abstract: Cement slurries are prepared that comprise water, a hydraulic cement and particles of an oil-absorbent material. The particles are present in an amount sufficient to alter a property of a non-aqueous drilling fluid. The cement slurry is placed in a subterranean well, whereupon the slurry contacts residual drilling fluid on casing and formation surfaces. The oil-absorbent material in the cement slurry may reduce the mobility of the drilling fluid, thereby improving zonal isolation.Type: GrantFiled: June 28, 2019Date of Patent: February 13, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Anatoly Vladimirovich Medvedev, Dominic Vincent Perroni, Laure Martin-Al-Khatib, Adam Ethan Keilers, Petr Kolchanov

Patent number: 10457848Abstract: A self-adaptive cement formulation includes cement, water and thermoplastic block-polymer particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.Type: GrantFiled: June 19, 2017Date of Patent: October 29, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Sylvaine Le Roy-Delage, Laure Martin-Al-Khatib
