摘要： A method is disclosed for low damage gravel packing. The method includes combining a carrier fluid, a first amount of particulates, and a second amount of particulates into a slurry. The first amount of particulates have a first average size distribution and the second amount of particulates have a second average size distribution, and the first average size distribution is at least three times larger than the second average size distribution. The slurry includes particles which are at least partially degradable material, and with reactive solid constituents. The reactive solid reacts with the degradable material and/or a hydrolysis product of the degradable material. The method further includes positioning a screen in a wellbore, and circulating the slurry through the wellbore such that the first amount of particulates and the second amount of particulates are deposited on an outer surface of the screen.

摘要： Methods of forming gravel packs while reducing fluid loss to the surrounding subterranean formation. The methods involve suspending gravel that has been coated with a tackifying agent and degradable fines into a low viscosity carrier fluid and then placing that suspension into a subterranean formation so as to form a gravel pack wherein, as the gravel pack is placed, the degradable fines to de-adhere from the gravel and to fill at least a portion of the pore spaces within the gravel pack so as to reducing fluid loss through the gravel pack.

摘要： An efficient oil based drilling fluid is provided that includes a polymer additive effective at imparting suspension characteristics without the presence of organophilic clays, while also providing filtration control. The fluid is shear thinning and has good fluid rheology over a broad temperature range. A preferred polymer for the additive is substantially linear and comprises mostly hydrophobic monomers and some hydrophilic monomers such as, for example, an emulsion copolymer of 2-ethylhexyl acrylate and acrylic acid.
