Abstract:
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.
