Abstract: In some aspects, a target net treating pressure for an injection treatment of a subterranean region is determined. Fracture growth orientation in a subterranean region is modeled by a computer system. In the model, the fracture growth is a response to fluid pressure acting on the subterranean region. A target net treating pressure for fluid acting on the subterranean region during an injection treatment of the subterranean region is determined based on the modeled fracture growth orientations.

Abstract: A well bore in a subterranean formation includes a signaling subsystem communicably coupled to injection tools installed in the well bore. Each injection tool controls a flow of fluid into an interval of the formation based on a state of the injection tool. Stresses in the subterranean formation are altered by creating fractures in the formation. Control signals are sent from the well bore surface through the signaling subsystem to the injection tools to modify the states of one or more of the injection tools. Fluid is injected into the stress-altered subterranean formation through the injection tools to create a fracture network in the subterranean formation. In some implementations, the state of each injection tool can be selectively and repeatedly manipulated based on signals transmitted from the well bore surface. In some implementations, stresses are modified and/or the fracture network is created along a substantial portion and/or the entire length of a horizontal well bore.

Abstract: A sand control screen assembly (100) positionable within a wellbore (26) for filtering particulate matter out of production fluids. The sand control screen assembly (100) includes a perforated base pipe (102) that allows fluid flow therethrough and a filter medium (124) disposed exteriorly about the base pipe (102). A surface-modified agent is disposed on at least a portion of the filter medium (124). The surface-modified agent is operable to enhance the surface filter characteristics of the filter medium (124), thereby reducing particulate infiltration into the filter medium (124).

Abstract: A sand control screen assembly (40) includes a base pipe (44) having a plurality of openings (45) in a sidewall portion thereof and a swellable material layer (46) disposed exteriorly of the base pipe (44) and having a plurality of openings (47) that correspond to the openings (45) of the base pipe (44). A plurality of telescoping perforations (48) are operably associated with the openings (45) of the base pipe (44) and at least partially disposed within the corresponding openings (47) of the swellable material layer (46). A filter medium (56) is disposed within each of the telescoping perforations (48). In operation, radial expansion of the swellable material layer (46), in response to contact with an activating fluid, causes the telescoping perforations (48) to radially outwardly extend.

Abstract: A sand control screen (40) includes a perforated base pipe (42) and a filter layer (50) that has micro-perforations (52) therein. The filter layer (50) is attached to the base pipe (42) along the entire length of the filter layer (50). Channels (46) are formed between the base pipe (42) and the filter layer (50) to allow fluid to flow therebetween. The sand control screen (40) is formed by micro-perforating a length of material, such as sheet metal, to form the filter layer (50), creating channels (46) that will allow fluids to flow between the base pipe (42) and filter layer (50), wrapping the filter layer (50) around the base pipe (42), attaching the filter layer (50) to the base pipe (42) along the length of the filter layer (50) and creating a seam between the two edges of the filter layer (50).

Abstract: 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.

Abstract: A method and apparatus for fracturing a formation or gravel packing a borehole extending through an unconsolidated subterranean zone in a formation includes a screen assembly having a length adapted for disposal adjacent the unconsolidated subterranean zone and includes a plurality of screens mounted on a base member with adjacent base members being connected by a sub having an aperture in the wall thereof. A flow-control service assembly is disposed within the bore of 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. The apertures in the screen assembly are disposed along the length of screen assembly at predetermined intervals. The inner tubular member and outer tubular member form an inner annulus, the outer tubular member and screen assembly form a medial annulus, and the screen assembly forms an outer annulus with the wall of the borehole.
