    摘要: The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

    摘要: The present invention relates to gelled fluids and methods for using liquefied petroleum gas in subterranean operations. More particularly, the present invention relates to servicing fluids that comprise gelled liquefied petroleum gas or servicing fluids that comprise a conventional gelled hydrocarbon fluid with liquefied petroleum gas and methods of using such servicing fluids in subterranean formations. One embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of providing a gelled LPG fluid comprising liquefied petroleum gas and a gelling agent; and placing the gelled LPG fluid into the subterranean formation. Another embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of providing a combined LPG servicing fluid comprising liquefied petroleum gas and a conventional hydrocarbon servicing fluid; and placing the combined LPG servicing fluid into the subterranean formation.

    摘要: The present invention relates to emulsion compositions and associated methods. More particularly, the present invention relates to gelled invert emulsion compositions and their associated methods of use and preparation. In one embodiment, the present invention provides a method of treating a portion of a subterranean formation comprising the steps of: providing a gelled invert emulsion composition that comprises an oleaginous continuous phase, a discontinuous phase, and a gelling agent; and treating a portion of the subterranean formation. The present invention also provides methods of increasing the viscosity of an invert emulsion composition, methods of making gelled invert emulsion compositions, methods of providing some degree of sand control to portions of subterranean formations, methods of fracturing a portion of a subterranean formation, and gelled invert emulsion compositions.
