摘要： A retrievable screen apparatus provides increased filtration in a retrievable screen disposed within a receptacle, the receptacle being positioned in a subterranean well. The receptacle has a lower filtration screen attached thereto for filtering larger particles, such as gravel and proppant, from fluid flow within the well. Thus, the retrievable screen may be retrieved and replaced, leaving the receptacle operatively positioned in the well.

摘要： A fluid breaking composition including an effective amount of an alkali chlorite and/or hyperchlorite is disclosed, where the composition reduces a viscosity of a polymer viscosified fluid to a desired low value at down hole conditions within a time period coincident with a formation stimulation time, generally between about 30 minutes and 195 minutes. Methods for making and using the breaking composition are also disclosed.

摘要： The present invention provides a method of stimulating a subterranean formation penetrated by a well. The formation has a water-bearing section and a hydrocarbon-bearing section. The method includes the steps of: (a) introducing into the formation an aqueous treatment fluid containing a hydrophobically-modified relative permeability modifier, and (b) introducing an acidizing treatment fluid into the formation. The hydrophobically-modified RPM can be formed and introduced into the formation in several ways. For example, the hydrophobically-modified RPM can be the reaction product of a hydrophilic polymer and a hydrophobic compound that are capable of reacting with each other. The hydrophilic polymer is a polymer containing reactive amino groups in the polymer backbone or as pendant groups, which are capable of reacting with a hydrophobic alkyl halide compound. The hydrophobically-modified RPM can include, for example, a polymer of DMAEMA quaternized with an alkyl halide, wherein the alkyl halide has an alkyl chain length of 6 to 22 carbons.
