Patent ID: 7032663

Claim:
A method of controlling the production of particulates in a subterranean wellbore comprising the steps of: (a) preparing a permeable cement composition comprising a hydraulic cement, water, and a degradable material that comprises: (i) a degradable polymer chosen from the group consisting of chitins, chitosans, proteins, aliphatic polyesters, poly(lactides), poly(glycolides), poly(ε-caprolactones), poly(hydroxybutyrates), polyanhydrides, aliphatic polycarbonates, poly(orthoesters), poly(amino acids); poly(ethylene oxides), or polyphosphazenes; and/or (ii) a dehydrated salt which will degrade overtime as it hydrates (b) placing the permeable cement composition in an annulus between a screen and the walls of the well bore adjacent to a fluid producing zone; and (c) allowing the permeable cement composition to form a permeable cement mass in the annulus.
