    摘要: A method of controlling fines migration in a wellbore penetrating a subterranean formation, the method comprising: introducing into the wellbore a screen mesh in an unexpanded form disposed of a first tubular member having a body with apertures, the screen mesh comprising a degradable material; expanding the screen mesh; injecting a cement slurry into the wellbore to fill open spaces within the expanded screen mesh; allowing the cement slurry to set forming a set cement that reduces or substantially preventing the passage of formation particles from migrating from the subterranean formation into the wellbore; and removing the degradable material of the screen mesh forming a fluid pathway in the set cement, which allows a formation fluid to flow from the subterranean formation into the wellbore.

    摘要: An adaptable anchor including a frame; an arm articulated to the frame; a pad connected to the arm at a distance from the articulation with the frame; a wedge movably mounted to the frame and in wedging contact with the arm; a biasing member disposed to selectively apply a biasing energy between the frame and the wedge; and a degradable retainer preventing application of the biasing energy until degraded. An embodiment of a borehole system including a borehole in a subsurface formation; a tubular member disposed in the borehole; and an adaptable anchor as in any prior embodiment in operable contact with the tubular member. An embodiment of a method for anchoring a tool in a borehole including running the adaptable anchor as in any prior embodiment; degrading the degradable retainer; urging the wedge into contact with the arm with the biasing member; and displacing the pad.
