A downhole tool comprising a body and a sealing element, wherein the sealing element is composed of a composite material comprising a rubber and a degradable acrylate-based polymer, and wherein at least a portion of the degradable acrylate-based polymer degrades when exposed to an aqueous fluid in a wellbore environment.

Downhole tools comprising composite sealing elements

The present invention relates to downhole tools and methods of removing such tools from wellbores. More particularly, the present invention relates to downhole tools designed to be comprised of dissolvable materials or frangible materials and methods for dissolving or fragmenting such downhole tools in situ.

Downhole plug apparatus

A well tool including swellable material and integrated fluid for initiating swelling. A well tool includes a swellable material and a reservoir for containing a fluid of a type which causes the swellable material to swell. A method of swelling a swellable material included in a well tool includes the steps of: positioning the well tool in a well; and then activating a fluid to cause swelling of the swellable material. A method of swelling a swellable material includes the steps of: providing the swellable material which is capable of swelling when contacted by a fluid; positioning the swellable material in an environment in which the swellable material is contacted by another fluid which does not cause the material to swell; and swelling the swellable material by contacting the swellable material with the first fluid while the swellable material remains in contact with the other fluid.

Well tool including swellable material and integrated fluid for initiating swelling

A wellbore servicing tool comprising a housing comprising ports, a triggering system, a first sliding sleeve transitional from a first position to a second position, and a second sliding sleeve transitional from a first position to a second position, wherein, when in the first position, the first sliding sleeve retains the second sliding sleeve in the first position, wherein, when in the first position, the second sliding sleeve prevents a route of fluid communication via the one or more ports of the housing and, when is in the second position, the second sliding sleeve allows fluid communication via the ports, and wherein the triggering system is configured to allow the first sliding sleeve to transition from the first position to the second position responsive to recognition of a predetermined signal comprising a predetermined pressure signal, a predetermined temperature signal, a predetermined flow-rate signal, or combinations thereof.

Method of completing a multi-zone fracture stimulation treatment of a wellbore

A mechanism for use in a wellbore servicing tool includes a continuously rotating ring within a servicing tool, and a limiting mechanism configured to engage the ring and lock the ring upon a predetermined degree of rotation of the ring. The mechanism may comprise a portion of an actuation assembly for use in a wellbore.

Method to restrict the number of cycles in a continuous j-slot in a downhole tool

Methods and apparatuses for releasing a chemical in a well bore are disclosed. One apparatus includes a curved member configured for coupling to a casing, and a hollow member is connected to the curved member. A chemical container is disposed, at least in part, within the hollow space, and the hollow member extends at least partially around a hollow space.

Methods and apparatuses for releasing a chemical into a well bore upon command

High temperature imaging devices are disclosed. In one embodiment, the imaging device comprises an array of photosensitive elements fabricated on an insulator substrate, and an information storage component coupled to the array. The information storage component stores data representing one or more light patterns detected by the array. The light patterns may be images or spectral patterns. The insulator substrate may be a sapphire or spinel substrate. Alternatively, the substrate may be silicon carbide or an insulated silicon substrate. In at least some embodiments, a processor is integrated on the same substrate as the array.

High temperature imaging device

A system and method for determining load on a downhole tool according to which one or more sensors are embedded in one or more components of the tool or in a material on one or more of the components. The sensors are adapted to sense load on the components.

System and method for sensing load on a downhole tool

A method of treating a subterranean formation penetrated by a wellbore, according to which a tool is fabricated of a material that breaks up or dissolves in the presence of a fluid and is inserted in the wellbore for performing a function in the wellbore. The fluid is then introduced to the tool to break up or dissolve portions of the tool and the remaining portions of the tool fall to the bottom of the well.

Method for removing a tool from a well

A method of treating a subterranean formation surrounding a wellbore, according to which a tool inserted into the wellbore for performing a function in the wellbore is fabricated of a material that breaks up upon detonation of an explosive mounted on the tool, thus allowing the pieces of the tool to fall to the bottom of the wellbore.

The present invention provides a method for drilling, analyzing, and stabilizing subsurface formations. The system is generally formed around a reusable bottomhole assembly (BHA) that provides an anchoring and thrust mechanism, furnishing the necessary downward force needed to provide comminution of geological material in a borehole. The BHA is conveyed into the borehole via a communications link wireline equiped with internal power and data telemetry lines. The BHA permits the use of multiple comminution sampling and analysis tools via a coupling device. The BHA and communications link wireline are mounted so as to couple with different tools. The main drilling mechanism is a torque drive assembly powered coring tool. A borehole televiewer and/or logging analysis tool may follow each coring period. The final step in each coring period is a wellbore consolidation technique. This series of steps is then repeated, each time coring the wellbore to a deeper depth.

Method of drilling, analyzing and stabilizing a terrestrial or other planetary subsurface formation

An apparatus ( ) and method for sequentially packing an interval of a wellbore ( ) is disclosed. The apparatus ( ) comprises a cross-over assembly ( ) having first and second exit ports ( ). The cross-over assembly ( ) has a fracturing configuration wherein the first exit port ( ) is open and the second exit port ( ) is closed and a gravel packing configuration wherein the first exit port ( ) is closed and the second exit port ( ) is open. The apparatus ( ) also includes a gravel packing assembly ( ) that has an inlet that receives the gravel packing slurry from the second exit port ( ) and a plurality of outlets ( ) that allow for the delivery the gravel slurry to a plurality of locations along the length of a sand control screen ( ).

Apparatus and method for sequentially packing an interval of a wellbore

An apparatus and method for removing a frangible rupture disc or other frangible device from a wellbore casing. The casing has a special casing section defining a plurality of holes therethrough. Rupturable glass ceramic discs or inserts are disposed in the holes and retained therein. The glass ceramic discs or inserts are adapted to withstand fluid differential pressure normally present in the wellbore but are rupturable in response to impingement by a pressure wave thereon. The pressure wave is provided by a pressure wave generating device positionable in the casing string adjacent to the holes in the special casing section. The pressure generative device may generate a pressure pulse or an acoustical wave. Methods of perforating a well casing using a pressure pulse or an acoustical wave are also disclosed.
