A method includes providing an electrical submersible pump assembly (ESP) with a pump, an intake, a gel canister, a protector, and a motor disposed in a casing. The method includes providing fluid communication between a production tubing and the ESP, the production tubing delivering well fluid containing solid particles and liquids from the ESP into a wellhead assembly through an inner bore of the production tubing. The method includes locating a pressure release conduit configured in a closed state, between a canister exterior in a hydraulic communication with a canister inner chamber of the gel canister and the inner bore. The closed state prevents the hydraulic communication between the canister inner chamber and the inner bore. The method includes delivering a canister contents to the well fluid.

System and method to prevent solids fallback in ESP-lifted wells using gel

A method that includes disposing a packer and an ESP inside a production tubing bore. The ESP includes a pump, a discharge, a shroud, and a bypass sub coupled to the shroud. The shroud includes a closed end coupled to a base of the pump. The packer, coupled to an outer surface of the shroud, is located downstream of the bypass sub. The method includes circulating liquids from the pumping base through the discharge to a shroud open end downstream of the packer thereby sealing the packer between the outer surface and the production tubing bore. The method includes pumping, using the pump device, the liquids through the production tubing using the bypass sub and performing a production operation using the wellhead assembly to obtain an amount of gas production.

Reviving a well using through-tubing cable-deployed pump

A system for navigating a downhole environment includes a tube body with a flexible material that is formed as a thin-walled tube and a pump that pumps pressured fluid through the tube body. The tube body has at least a section that extends along a horizontal section of a downhole environment by the flexible material pushing out under the pressured fluid. A method for navigating a downhole environment includes providing a tube body with a flexible material which is formed as a thin-walled tube, pumping a first pressure through the tube body to extend the tube body by the flexible material pushing out at a tip of the tube body, and controlling the flexible material to extend the tube body along a horizontal section of a downhole environment.

A system includes a solids trap disposed in a well. The system includes an inner annulus, an outer annulus, and a chamber between the inner annulus and the outer annulus. A solids accumulation zone is formed in the chamber. A pump is fluidly connected to the solids trap. A fluid stream carrying solids flows from the pump. The fluid stream carrying solids is configured to follow a path delimited by the outer annulus and the chamber until the fluid stream deposits the solids in the solids accumulation zone and departs the solids trap via the inner annulus into a tubing.

Solid trap for ESP applications

A method for mitigating water invasion to a submersible motor includes: forming an accumulation zone within an inner space of the submersible motor, wherein the accumulation zone is disposed at a bottom of the inner space below a motor shaft; measuring a conductivity of a fluid inside the accumulation zone using a sensor, wherein the fluid comprises water and dielectric oil; comparing the conductivity of the fluid with a threshold value; upon detecting that the conductivity of the fluid is greater than the threshold value, activating a solenoid pump to discharge the fluid from the accumulation zone to an outside of the submersible motor.

A system includes a solids catcher that is centered with respect to a central axis of a tubing. The system includes an inner annulus, an outer annulus, and a chamber between the inner annulus and the outer annulus. A solids accumulation zone is formed in the chamber. A pump disposed offset from the central axis of the tubing. The pump is fluidly connected to the solids catcher through the outer annulus. A fluid stream carrying solids flowing from the pump. The fluid stream carrying solids is configured to follow a path delimited by the outer annulus and the chamber until the fluid stream deposits the solids in the solids accumulation zone and departs the solids catcher via the inner annulus into a tubing.

A fluid processing system is configured for use in a wellbore in a hydrocarbon-bearing rock formation. The system includes a casing liner disposed in an open hole section of a well for providing a separation zone in a flow of materials from a first reservoir The system includes a downhole separator operatively coupled to the casing liner for separating the first material and the second material within the flow of materials. The flow of materials includes at least a first material and a second material.

Systems and methods for processing downhole fluids

A chemical injection pump is installed below an electric submersible pump. In general, the chemical injection pump is either driven by an electric motor that draws power from the electric submersible pump motor or from energized fluid leaving the electric submersible pump output port. The electric submersible pump provides electric or hydraulic power to run the chemical injection pump.

Provided is a chemical injection pump that is installed below an electric submersible pump. In general, the chemical injection pump is either driven by an electric motor that draws power from the electric submersible pump motor or from energized fluid leaving the electric submersible pump output port. The electric submersible pump provides electric or hydraulic power to run the chemical injection pump. Therefore, no surface chemical injection pump is required and hence less space is needed.
