20080196797 | Flow formed high strength material for safety systems and other high pressure applications - A method for making a downhole tool material for a hydrocarbon well that includes solution heat treating a precipitation hardening nickel alloy; cold working the alloy following the solution heat treating; aging the alloy following the cold working and the material made therefrom. | 08-21-2008 |
20090050314 | Surface improvement for erosion resistance - The technique of laser induced surface improvement is used for tool surfaces in downhole tools that experience erosion from slurry or high velocity flows. | 02-26-2009 |
20090101354 | Water Sensing Devices and Methods Utilizing Same to Control Flow of Subsurface Fluids - An apparatus for controlling fluid flow in a wellbore includes a reactive element that reacts when exposed to a fluid and a flow control device configured to control a flow of the fluid. The flow control device may be actuated by a reaction of the reactive element to the fluid. In embodiments, the reactive element reacts by exhibiting a change in a material property. The reaction of the reactive element may be reversible. In embodiments, the reactive element may be a shape memory polymer. The flow control device may include an actuating element operably coupled to the reactive element. The reaction of the reactive element to a given fluid releases the actuating element to actuate the flow control device. | 04-23-2009 |
20090114395 | DENSITY ACTUATABLE DOWNHOLE MEMBER AND METHODS - Disclosed herein is an actuatable downhole member. The actuatable downhole member includes, a downhole member with a selected density, the selected density being comparable to an anticipated downhole fluid density such that a difference in the density of the downhole member and the density of the downhole fluid creates a bias on the downhole member to actuate the downhole member. | 05-07-2009 |
20090145609 | Valve Responsive to Fluid Properties - A valve for downhole use has the ability to throttle between fully open and closed and is fully variable in positions in between. The valve is preferably responsive to flowing fluid viscosity and uses a three dimensional flow through restrictor in combination with a relatively movable cover. At a given flow, a higher viscosity fluid will create a greater relative movement and make it possible for flowing fluid to bypass more of the flow through member. In a particular application involving production from a zone, an array of such valves can allow more production where the viscosity is higher and less production where the viscosity drops due to, for example, water production. | 06-11-2009 |
20090173498 | Screen coupler for modular screen packs - A coupler for gravel packing completions comprising an annular member having an upper end, a lower end, at least one flange disposed along an inner wall surface of the annular member intermediate the upper and lower ends, and at least one deformable portion is disclosed. The coupler may be used to connect one or more screens to a base pipe in a gravel packing completion by deforming the deformable portion such as by passing a swage over the outer wall surface of the annular member. In a similar manner, the coupler may also be used to connect a gravel packing completion component, such as an inflow control device to the base pipe of the gravel packing completion, to contemporaneously connect a screen section and a gravel pakcing completion component to the base pipe. | 07-09-2009 |
20100011559 | Retrofit Seals and Method for Placement in an Existing Groove - A seal is retrofit to an existing seal groove and made whole after being positioned in the groove. It can be an initial coil shape to allow it to slip over a shaft to get to the groove or it can be in a plurality of sections that are joined in place. The sections can be abutting or overlapping and are preferably coated with a brazing material that will ultimately join such ends. The ends can then have a nano-engineered coating that comprises alternating layers of aluminum and nickel that when initiated with applied heat becomes reactive exothermically to join the ends using the brazing material. | 01-21-2010 |
20100012323 | BEAD PACK BRAZING WITH ENERGETICS - A method of making porous shapes from unit structures such as beads involves coating the beads with two or more layers of material deposited such that it forms an energetic material. These bi-layer energetic materials are formed from a variety of materials including, but not limited to: Ti & B, Zr & B, Hf & B, Ti & C, Zr & C, Hf & C, Ti & Si, Zr & Si, Nb & Si, Ni & Al, Zr & Al, or Pd & Al, all of which can be deposited from vapor. Pressure is applied to prevent the components from moving and the solid-state reaction between the alternating layers produces exothermic heat. Heat from the reaction alone or in conjunction of an applied brazing compound joins the beads forming a porous shape that is desired. The reaction in the materials may be activated with a small pulse of local energy that can be applied using optical, electrical, or thermal sources. Common examples include an electrical pulse, spark, hot filament, a laser beam, etc. The method reduces energy consumption and the need for specialized equipment. The reactive materials and optional brazing material are preferably applied in a fluidized CVD furnace. | 01-21-2010 |
20100294510 | DISSOLVABLE DOWNHOLE TOOL, METHOD OF MAKING AND USING - Disclosed herein is a dissolvable downhole tool. The tool includes, a dissolvable body constructed of at least two materials and at least one of the at least two materials is a reactive material, and a first material of the at least two materials being configured to substantially dissolve the dissolvable body and a second material configured to control reaction timing of the first material. | 11-25-2010 |
