A pile can include: an elongated member; and a grout at least partially coupled to and for anchoring the elongated member, comprising: a resin; and a boron nitride nanotube structure comprising a boron nitride nanotube having a hexagonal boron nitride structure epitaxial to the boron nitride nanotube, wherein the grout has a first volume substantially free of the boron nitride nanotube structure, and a second volume comprising the boron nitride nanotube structure.

Grout having a resin-based system for anchoring, and methods relating thereto

Methods of the present disclosure relate to tailoring cement compositions to withstand carbon dioxide injection. A method comprises predicting a depth of carbonation in a cement sheath; predicting spatially varying mechanical properties of the cement composition due to the carbonation; and determining a mechanical response of the cement sheath based on the spatially varying mechanical properties of the cement composition.

Method to tailor cement composition to withstand carbon dioxide injection loads

Methods of wellbore cementing are provided. A method of generating a wellbore treatment fluid may include: classifying a plurality of solid particulates using correlations; calculating a reactive index and/or a water requirement for at least one of the solid particulates; and selecting two or more solid particulates from the plurality of solid particulates to create a wellbore treatment fluid.

Slurry design process

Systems and methods related to preparing foamed cement for laboratory analysis are provided. A prepared cement slurry is placed in a cement reservoir cell configured to pressurize the cement slurry contained within the cement reservoir cell to a capture pressure. After pressurization, the cement slurry and a compressed gas are introduced into a foam generator. Foamed cement generated in the foam generator is introduced from the tee into a foam capture cell where it can cure prior to analysis.

System and method of producing foamed cement in a laboratory environment

Methods of wellbore cementing are provided. A method of designing a cement composition may include: selecting a target heat of hydration for a target time and temperature; selecting one or more cementitious components and a weight percent for each of the one or more cementitious components such that a sum of a heat of hydration of the one or more cementitious components is less than or equal to the target heat of hydration; preparing the cement composition; and allowing the cement composition to set.

Control heat of hydration by characterizing cementitious components

Reactivity mapping methods are provided. A method may include: analyzing each of a group of inorganic particles to generate data about physical and/or chemical properties of the inorganic particles; and generating correlations between the properties of inorganic particles based on the data.

Reactivity mapping

Methods and systems including a wellbore having a pipe string extending through a wellhead and into the wellbore, wherein an annulus is formed between the pipe string and the wellbore, an isolation device that closes the wellbore in a closed pressure loop, a choke line in fluid communication with an interior of the pipe string through an outlet port of the wellhead, a choke valve fluidly coupled to the outlet port of the wellhead, wherein the choke valve is manipulable to control fluid flow through the choke line, and a crossover tool in the wellbore to divert incoming fluid from the interior of the pipe string to the annulus.

Managed pressure reverse cementing

Various embodiments include methods and systems structured to provide an indication of the status of a cementing operation in a wellbore. Electromagnetic radiation from a source can be directed to a fluid region in or around a casing in a wellbore, where an electromagnetic response can be detected from interaction of the electromagnetic radiation in the fluid region. Presence or absence of cement in the fluid region can be determined based the electromagnetic response. Additional apparatus, systems, and methods can be implemented in a variety of applications.

Cementing indication system

A method of detecting the presence of a downhole fluid at a particular location in a wellbore including pumping an activating fluid into a wellbore; contacting a flow controlling device in a pipe string casing with the activating fluid, the flow controlling device comprising at least one swellable element; activating the at least one swellable element in the flow controlling device; blocking fluids or controlling the flow of fluids entering or leaving the casing with the activated flow controlling device; allowing the pressure to change; and detecting the pressure change. An apparatus includes a pipe string in a wellbore and a flow controlling device in the pipe string casing, wherein the flow controlling device includes at least one swellable element, wherein upon activation, the at least one swellable element swells and fully or partially seals off the flow area of the flow controlling device.

Swellable technology for downhole fluids detection

A method and system for treating a subterranean formation involves detecting the displacement and position of a downhole fluid having a pH through the fluids reaction with a pH-sensitive material, mobilizing a plug assembly comprising the material to contact one or more constrictions in a wellbore casing.

pH-sensitive chemicals for downhole fluid sensing and communication with the surface

Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

System and method for the detection and transmission of downhole fluid status

A material detection and sealing device includes a body comprising a bottom end and a top end, and configured to fit within a casing string. The device includes a valve located within the body configured to open and close an orifice formed through the body. The device also includes a density meter located on or within the body configured to continuously sense the density of a neighboring fluid. The valve is configured to close upon the density meter sensing a certain density condition.
