摘要： Disclosed are improved methods and apparatus for improving the production of hydrocarbons from wells having gravel pack in a production zone. The methods and apparatus basically comprise the steps of entering a gravel packed well and perforating the gravel pack screen and fracture packing the formation through the screen perforations. At least the last portion of the particulate is preferably coated with a consolidator that will form a proppant pack. Installing a second screen in the well to overlap the perforations in the gravel pack screen to prevent the particulate from reentering the well.

摘要： An apparatus (38) and method for progressively gravel packing an interval of a wellbore (32) is disclosed. The apparatus (38) comprises a sand control screen (52) that is positioned within the wellbore (32) and a tubular member (42) that is disposed within the wellbore (32) forming a first annulus (56) with the sand control screen (52) and a second annulus (58) with the wellbore (32). The tubular member (42) initially prevents fluid communication between the first annulus (56) and the second annulus (58). Once the gravel packing operation begins, however, the tubular member (42) selectively allows fluid communication from the first annulus (56) to the second annulus (58) by progressively establishing fluid communication between the first annulus (56) and the second annulus (58) from a first end of the interval (48) to a second end of the interval (48).

摘要： A method for fracturing a formation or gravel packing a borehole using a screen assembly having a plurality of screens mounted on a base member and a plurality of apertures disposed at predetermined intervals along the screen assembly. A flow-control service assembly is disposed within the screen assembly and includes an outer tubular member and an inner tubular member. The outer tubular member includes a plurality of ports that communicate with the apertures in the screen assembly. Barriers are placed around the ports on the outer tubular member to prevent the formation of gravel bridges across the inner annulus between the inner tubular member and outer tubular member. The inner annulus provides alternative flow paths around the ports upon the ports becoming closed to fluid flow such as by bridges.

摘要： An apparatus (60) and method for gravel packing an interval of a wellbore is disclosed. The apparatus (60) comprises a sand control screen (78) that is positioned within the wellbore and a tube and manifold system (62) positioned between the sand control screen (78) and the wellbore. The tube and manifold system (62) delivers a fluid slurry to a plurality of levels within the interval when the apparatus (60) is in an operable position. The tubes (64, 70, 76) of the tube and manifold system (62) have first and second ends which are open such that the fluid slurry may enter one end, travel through the entire length of the tube (64, 70, 76) and exit the other end. The manifolds (66, 72) of the tube and manifold system (62) each have at least one exit port (68, 74) for the discharge of the fluid slurry from the tube and manifold system (62).

摘要： A method and well tool for using a low-viscosity slurry to gravel pack a completion interval. The well tool is comprised of a screen and at least one alternate flowpath which is initially closed to flow by a valve means. Once a sand bridge is formed in the completion interval, the pressure of the pumped slurry increases which, in turn, opens the valve means to allow flow through the alternate flowpath. Preferably, a plurality of flowpaths of different lengths are provided, all of which include valve means which are adapted to open at different pressures.

摘要： Improved methods and apparatus for completing an unconsolidated subterranean zone penetrated by a well bore are provided. The methods basically comprise the steps of placing a slotted liner having an internal sand screen disposed therein with dividers extending between the screen and liner, isolating the slotted liner and the well bore in the zone and injecting particulate material into flow paths formed by the dividers between the sand screen and the slotted liner and into the annulus between the slotted liner and the well bore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids.
