Abstract: A downhole assembly comprises a disintegrable article comprising a metal, a metal alloy, a metal composite, or a combination comprising at least one of the foregoing; the disintegrable article being corrodible in a downhole fluid; a current source configured to supply electrons to the disintegrable article and to delay or reduce the corrosion of the disintegrable article in the downhole fluid; and a controller configured to control the supply of electrons to the disintegrable article.

Abstract: A downhole tool for controlling the flow of a fluid in a wellbore includes a component that comprises: a cementitious material; an aggregate; and a ductility modifying agent comprising one or more of the following: an ionomer; a functionalized filler; the functionalized filler comprising one or more of the following: functionalized carbon; functionalized clay; functionalized silica; functionalized alumina; functionalized zirconia; functionalized titanium dioxide; functionalized silsesquioxane; functionalized halloysite; or functionalized boron nitride; a metallic fiber; or a polymeric fiber.

Abstract: A method of cementing a wellbore penetrating a subterranean formation comprises: injecting into the wellbore a cementing composition comprising: a ductility modifying agent comprising one or more of the following: an ionomer; a functionalized carbon; a metallic fiber; or a polymeric fiber; a cementitious material; an aggregate; and an aqueous carrier.

Abstract: A device, system, and method for locating collars along a casing string. The device includes a casing collar locator (CCL) and a valve in communication with the CCL connected to a work string. Fluid is pumped down the work string as the device is used to locate collars along a string. Upon detection of a collar, the CCL sends a signal to the valve, which causes the actuation of the valve to decreases a flow area within a work string. The decrease in flow area causes a pressure increase within the work string, which may be detected at the surface to indicate the detection of a collar. The device may include an amplifier and power source to amplify the signal from the CCL to the valve. The CCL may detect collars by a change in magnetic flux or by the detection of a signal emitted by individual collars.

Abstract: A downhole treatment tool including a housing having one or more openings and one or more ports. A sleeve disposed in movable relationship to the housing. The sleeve having one or more apertures that upon movement of the sleeve are selectively positionable among positions of unaligned, aligned with the one or more openings or aligned with the one or more ports. A method for treating a downhole location.

Abstract: An intelligent dart or ball or other shape is dropped or pumped into a borehole that has multiple valves for access to the formation through which fractures are initiated. The intelligent object engages with the valves as it passes with retractable engagement dogs that are outwardly biased but not to the degree needed to find support unless the valve in question is the one that needs to be operated. In that event the dogs become supported and pressure is applied to the object to shift the valve to the open position. The object can be released at a later time remotely or can be milled out. Subsequent objects can be landed in the same sleeve after the initial object is released to close it or to close the open port by moving a second sleeve against a first sleeve. Fracturing in any order is envisioned.

Abstract: A first sleeve is shifted with a ball landed on a seat to open treating ports. At the conclusion of the treating such as fracturing, another ball is dropped on a seat in an adjacent sleeve. The adjacent sleeve shifts to contact the initial sleeve that was shifted earlier. When the sleeves abut the treating ports are closed by the second sleeve and the production ports that are preferably screened are also opened by the shifting of the second sleeve against the first sleeve. The first sleeve hits a travel stop in the housing to produce the full open position for the treating ports. The balls can be progressively larger in a bottom up direction for the procedure or the balls can all be the same size as the landing of a ball on the first sleeve reconfigures the sleeve above for the same sized ball.

Abstract: A sand control sleeve includes a body; a port extending through the body; and a filtration material disposed relative the port and configured to attain a first condition where relatively less of the port is occupied. A second condition where relatively more of the port is occupied by the material. A method for producing fluid.
