摘要： A method of gravel packing a wellbore penetrating a subterranean formation. The wellbore has a cased section and an uncased section and contains synthetic or oil-based drilling fluids containing drilled solids. To carry out the method, fresh synthetic or oil-based displacement fluid that is free of drilled solids is introduced into the wellbore to displace the synthetic or oil-based drilling fluids from the uncased section of the wellbore. A water-based displacement fluid is introduced into the wellbore to displace fluids within the cased section of the wellbore. A sand control screen assembly is run to a selected depth within the uncased section of the wellbore. A gravel pack slurry containing gravel and a water-based carrier fluid is then introduced into the wellbore.

摘要： A method for removing drilling damage from a formation in a wellbore that has not been produced includes injecting a chemical-acting cleanup fluid and contacting it with a filtercake on a face of a formation of interest for a period of time sufficient to loosen some of the solids embedded in the filtercake. The method further includes circulating a solids removal fluid at a high rate through the wellbore across the face of the formation of interest, the solids removal fluid including a viscosifier, and positioning a second treatment fluid having a fluid loss control pill in the wellbore at the formation of interest. The method further includes degrading particles of the fluid loss control pill and degrading remaining bridging agent from the drilling fluid.

摘要： A method of installing a sand control screen assembly in a wellbore penetrating a subterranean formation is carried out in a wellbore having a cased section and an uncased section. The wellbore contains synthetic or oil-based drilling fluids containing drilled solids. A first water-based displacement fluid that contains a shale inhibitor is introduced into the wellbore to displace the synthetic or oil-based drilling fluids from the uncased section of the wellbore. A second water-based displacement fluid is introduced into the wellbore to displace fluids within the cased section of the wellbore. The sand control screen assembly is then run to a selected depth within the uncased section of the wellbore to facilitate a gravel packing operation.
