摘要： An expandable well screen has a desirable thin-wall construction together with a simplified fabrication method. In fabricating the screen, a flexible sheet of metal mesh filter media is diffusion bonded to an inner side of a perforated metal sheet which is then deformed to a tubular shape to form a filter structure having an outer perforated tubular shroud interiorly lined with the filter media. The tubular filter structure is telescoped onto a perforated base pipe and has its opposite ends sealingly secured thereto to complete the expandable well screen.

摘要： A gravel pack apparatus and associated method of completing subterranean wells provides convenient and economical gravel packing operations, permitting a sand control screen to be run into the well attached to the apparatus which is, in turn, attached to production tubing, and further permitting the tubing to be detached from the screen. In a preferred embodiment, a gravel pack apparatus has interoperable valve and tubing release portions. The valve portion may be closed after the gravel packing operation is completed. Closure of the valve portion activates the release portion, permitting the apparatus to be separated.

摘要： A formation fracturing and gravel packing tool and associated methods provide high flow rates and volumes of slurry delivery in a relatively small bore well. In a described embodiment, a formation fracturing tool has a telescoping travel joint and a washpipe within an assembly including a packer, a circulating sleeve and a screen. The packer is set in the well, the travel joint is extended, the travel joint is locked in its extended configuration, a slurry is flowed through the circulating sleeve, the extended travel joint is latched onto the washpipe, and the travel joint and washpipe are retrieved to the earth's surface.

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： In accordance with the teachings of the present invention, a system and method for forming a seal within tubing is provided. A section of tubing is installed in a borehole. The tubing has an inflatable element disposed along an inner surface of the tubing. The inflatable element is predisposed to expand inwardly under fluid pressure. A fluid pressure is applied to the inflatable element using a tool within the tubing, and the inflatable element is expanded to form a seal within the tubing.

摘要： A sand control screen assembly (60) comprises a base pipe (62) having at least one opening (64) that allows fluid flow therethrough and a filter medium (66) positioned about the exterior of the base pipe (62) that allows fluid flow therethrough and prevents particulate flow therethrough. An inflatable seal member (72) is disposed within the at least one opening (64) of the base pipe (62) and controls fluid flow through the at least one opening (64). An inflation fluid source (74) is in fluid communication with the inflatable seal member (72) and provides an inflation fluid to the inflatable seal member (72) to selectively urge the inflatable seal member (72) into sealing engagement with the at least one opening (64).
