A method of treating a subterranean formation to protect against solid deposition and corrosion attack includes flowing a pre-flush fluid to a specified downhole location within the subterranean formation. A main treatment fluid is flowed to the specified downhole location. The main treatment fluid includes a scale inhibitor configured to inhibit formation of scale within the subterranean formation. At a subsurface level, an overflush foam is generated. The overflush foam includes an aqueous fluid and a gas. The overflush foam is shear thinning and non-Newtonian. The overflush foam is flowed to the specified downhole location.

Foamed squeeze treatment in wells

A method, system, and non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for determining remediation categories for a plurality of wells include: obtaining, by a computer processor, a plurality of attributions for the plurality of wells; obtaining, by the computer processor, a set of weightages for each of the plurality of attributes for the plurality of wells; generating, by the computer processor, a first Well Health Index (WHI) set for a well among the plurality of wells; generating, by the computer processor, a second WHI set for the well; determining, by the computer processor, a sum of weightages of the second WHI set for the well; determining, by the computer processor, a remediation category among a plurality of remediation categories for the well based on the sum of weightages; and generating, by the computer processor, tracking notifications and action reports for the well.

System and method for identifying productive health of wells while ensuring safe operating conditions

A valve capsule assembly for a well includes a body including a first end, a second end, a cavity, and an exterior surface. The body is sized for positioning inside a bore of a casing. A sealing element is coupled to the exterior surface of the body and is configured for sealing with an interior surface of the casing. A cone is movably disposed in the cavity of the body between the sealing element and the second end of the body. A slip coupled to the exterior surface of the body and is movable between a deactivated configuration and an activated configuration, in which the slip is configured to expand and engage with the interior surface of the casing. When the cone is in a first position, the slip is in the deactivated configuration and when the cone is in a second position, the slip is in the activated configuration.

A method for determining a cathodic current (such as from a cathodic protection system) in a tubular disposed within a wellbore drilled in a subterranean zone. A electromagnetic tool disposed within the tubular includes an electromagnetic transmitter, an electromagnetic receiver, a helical transmitter coil, and a helical receiver coil. An axis of the helical transmitter coil and an axis of the helical receiver coil are substantially parallel to an axis of the tubular. An electromagnetic field is transmitted by flowing a first electrical current to the helical transmitter coil. During the transmitting, an electromagnetic signal is received by the electromagnetic receiver via the helical receiver coil. A second electrical current is calculated based on the electromagnetic signal received by the electromagnetic receiver. A magnitude of the cathodic current flowing through the tubular is calculated based on a difference between the first electrical current and the second electrical current.

Cathodic current measurement of outer casings or tubulars using electro-magnetic radiation

A method includes monitoring fluid production at a passive ICD installed in a base pipe in a wellbore. Responsive to monitored fluid production meeting one or more predetermined criteria, a remedial sleeve component is installed for the passive ICD. The remedial sleeve component includes: one or more ports which permit throughput of fluid into the base pipe; a closing portion which selectively opens and closes the one or more ports; and one or more sealing portions, which prevent a flow of fluid into the base pipe when the one or more ports are closed. The one or more ports are selectively opened or closed responsive to one or more additional predetermined criteria. A related system includes an actuation tool which deploys into the wellbore to actuate the closing portion to selectively open and close the one or more ports.

A system for acquiring data in a well may have a tubing placed therein. The system may include a pass-through device. The pass-through device may include a cylindrical housing having a central aperture extending through the cylindrical housing along a central axis thereof. The pass-through device may include a first sensor mounted on the cylindrical housing. The pass-through device may include a first communication device mounted on the cylindrical housing and operatively connected to the first sensor. The system may include a tubing mounting structure secured to the tubing and configured to hold the pass-through device at a desired location within the tubing. The system may include a control device. The control device may include a second communication device configured to communicate with the first communication device. The control device includes a processor operatively connected to the second communication device.
