A system and apparatus for providing an apparatus for use in a wellbore. The apparatus includes an apparatus body defining a volume, a propellant disposed within the volume, wherein the propellant has a first burn rate, and at least one propellant insert disposed within the propellant, wherein the propellant insert has a second burn rate, and the second burn rate is different than the first burn rate.

System and method for altering a burn rate of a propellant

A method of stabilizing one or more clays within a subterranean formation comprises forming at least one treatment fluid comprising anionic silica particles, cationic silica particles, and at least one base material. The at least one treatment fluid is provided into a subterranean formation containing clay particles to attach at least a portion of the anionic silica particles and the cationic silica particles to surfaces of the clay particles and form stabilized clay particles. A method of treating one or more clays contained within a subterranean formation, and a treatment fluid for a subterranean formation.

Treatment fluids for a subterranean formation

A hybrid article comprises a disintegrable metal comprising one or more of the following: Mg; Al; Zn; Mn; an alloy thereof; or a composite thereof; and a disintegrable polymer comprising one or more of the following: an epoxy polymer derived from an epoxy base and a curing agent having cleavable bonds; a cured cyanate ester; or a poly(hexahydrotriazine).

Hybrid disintegrable articles

A method of manufacturing an article comprises depositing a metallic powder on a substrate or a worktable; fusing the metallic powder according to a preset pattern; and adjusting a composition of the metallic powder or a condition to fuse the metallic powder or a combination thereof to additively form an article such that the article has a first portion and a second portion, wherein the first portion has one or more of the following properties different than those of the second portion: corrosion rate; tensile strength; compressive strength; modulus; or hardness.

Additive manufacturing of functionally gradient degradable tools

A downhole article comprises a polymer substrate having a surface that is configured for exposure to a well fluid; the substrate comprising a thermoplastic material, an elastomer, or a combination comprising at least one of the foregoing; and a coating disposed on the surface of the polymer substrate; the coating comprising a fluorinated poly-para-xylylene.

High temperature hydrophobic chemical resistant coating for downhole applications

An article comprises a plurality of micro-sized or nano-sized galvanic cells, wherein the article has a seamless structure encompassing a plurality of empty spaces of different sizes, geometries, distributions, or a combination thereof, and one or more of the following properties of the article vary in different directions: tensile strength; compressive strength; electrical resistance; thermal conductance; modulus; or hardness.

Methods of stabilizing clays within a subterranean formation

A sensor for detecting well conditions includes at least one transducer positioned at an end of the carrier. The carrier is positioned adjacent to and exposed to a wellbore wall and the transducer is configured to generate mechanical waves in the carrier. The carrier conveys the mechanical waves and has one or more sections initially free of a physical deformation that causes reflection of the mechanical waves. The sections physically deform to cause reflected mechanical waves when subjected to a loading from the formation. The transducer generates a signal representative of reflected mechanical waves received at the end of the carrier. The location of the loading is estimated using the received signal.

Formation collapse sensor and related methods

A downhole sealant includes a composition that includes a polymer; an absorbent material; a primary crosslink network including primary bonds between chains of the polymer; and a secondary crosslink network which is transient. A method of regulating the swell rate of the downhole sealant includes disposing a downhole sealant comprising a polymer and an absorbent material in a borehole; maintaining a primary crosslink network of the polymer; and decomposing a secondary crosslink network of the absorbent material in response to a condition to regulate the swell rate of the downhole sealant.

Self-inhibited swell packer compound

A system for separating fluids of a fluid mixture including a filter element operatively arranged for enabling a first component of a fluid mixture to flow therethrough while impeding flow of at least one other fluid component of the fluid mixture. An additive is configured to improve a first affinity of the filter element for the first component relative to a second affinity of the filter element for the at least one other fluid component of the fluid mixture. A method of separating fluids is also included.

Downhole fluid separation system and method

Methods, systems, and apparatuses for downhole sampling are presented. The sampling system includes a control unit and a housing to engage a conduit. The housing at least partially encloses at least one formation sampler to collect a formation sample. The formation sampler is stored in a sampler carousel. A sampler propulsion system forces the formation sampler into the formation. The propulsion system is in communication with the control unit.

Downhole formation sampling

An embodiment includes an apparatus that includes a sample carrier adapted to receive a sample and return it to the surface. An embodiment includes a formation tester adapted to load the sample carrier. An embodiment includes a retriever to remove the carrier from the drilling mud. The retriever also includes a device for removing the sample from the carrier.

Method and apparatus for downhole sampling

New compositions have been discovered which are useful as slurry concentrates to carry solid particles along in a fluid. A non-limiting example would be to carry proppants in a concentrate to a completion fluid being pumped downhole in a hydrocarbon recovery operation. The composition employs both a trivalent salt, such as aluminum chlorohydrate, as a viscosifying agent, and a surfactant. Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant in that less of each component is required when both are used together to suspend the same amount of solids, than if one or the other is used separately. The viscoelasticity of the concentrate may be easily broken by dilution; other mechanisms are also anticipated.
