A flow control system includes a conduit having an interior surface, and a flow control device connected to the interior surface of the conduit and disposed along the interior surface of the conduit for a first length. The flow control device includes an expandable element that expands inwardly from the interior surface, from a retracted position to an expanded position. The expandable element defines at least a portion of a flow path configured to control a flow of fluid through the conduit.

Flow control in pipelines

A bottom hole assembly includes a production logging tool including a spinner flowmeter for determination of flow velocity within production tubing, and a downhole scale removal tool coupled to the production logging tool. The downhole scale removal tool includes an elongate body defining an internal flowpath therein, one or more openings defined on an outer surface of the elongate body, the one or more openings fluidly coupled to the internal flowpath, and a plurality of solid bristles disposed on an outer surface of the elongate body and extending radially from the elongate body.

Downhole scale removal tool

A well system includes a well extending from a surface into a formation, a Y-tool provided at an end of a tubing string extending through the well, a concentric coiled tubing string extending through the tubing string and through a bypass line of the Y-tool, and a plurality of treatment solutions provided at the surface of the well. The plurality of treatment solutions includes at least one component of a dissolvable gel, a gel dissolving solution, and at least one component of a non-dissolvable gel. A method for plugging a water zone in a hydrocarbon bearing formation and a method for reducing a concentration of produced water from a hydrocarbon bearing formation are also described.

Process of water shut off in vertical wells completed with electrical submersible pumps

A method includes conveying a straddle packer assembly into a wellbore that provides a water production zone and first and second oil production zones, the water production zone interposing the first and second oil production zones, deploying the straddle packer assembly and thereby isolating the water production zone from the first and second oil production zones, injecting an injection fluid into the water production zone from the straddle packer assembly, and preventing the influx of water from the water production zone into the wellbore with the injection fluid.

Method and system for mitigating downhole water production

A system includes a casing, a tubing within the casing, a packer, and a colloidal silica gel. The casing inner surface and the tubing outer surface define an annular space, and the packer is within the annular space. The colloidal silica gel which seals a gap. The gap can be a gap between the inner surface of the casing and a surface of the packer, a gap between the outer surface of the tubing and a surface of the packer, and/or a gap extending through the packer. A well can include such a system. A method of sealing a leak in or near a packer present in an annular space between a production casing inner surface and a tubing outer surface includes disposing a composition within the annular space, the composition comprising colloidal silica, water, and an activator. The method also includes allowing colloidal silica to precipitate from the composition to provide a colloidal silica gel within the annular space, wherein the colloidal silica seals a gap that can be a gap between the inner surface of the production casing and a surface of the packer, a gap between the outer surface of the tubing and a surface of the packer, and/or a gap extending through the packer.
