A method for isolating a horizontal tie-in pipeline of an inactive hydrocarbon-producing well from a main pipeline to prevent flow of hydrocarbons into the tie-in pipeline includes the steps of: identifying a location of a junction of the tie-in pipeline and the main pipeline and cleaning the tie-in pipeline by deploying a locating and cleaning assembly into the tie-in pipeline, withdrawing the locating and cleaning assembly, deploying a plug device having a longitudinally extending forward probe and a sealing element to the location of the junction, and remotely actuating the sealing element. The locating and cleaning device includes a pipeline junction sensing element longitudinally extending from a forward end of the locating and cleaning device. The sensing element is connected to a valve which, when open, relieves pressure in the locating and cleaning assembly as an indicator of the location of the junction.

Methods for treating fluids used in the production and/or transport of petroleum products and natural gas, and methods for the removal of acidic gases encountered in fluids used and encountered in such operations are provided. In one embodiment, the methods include introducing a treatment fluid including a polymeric swellable acid scavenger that includes at least one polymeric composition into a wellbore penetrating at least a portion of a subterranean formation in which an acidic gas, an acid-containing fluid, or both, are present.

A method may include obtaining caliper log data regarding a well. The method may further include determining, using a descaling model and the caliper log data, various predicted caliper log values for a descaled well. The descaled well may correspond to the well following a scale treatment. The method may further include determining whether the descaled well satisfies a predetermined criterion based on the predicted caliper log values. The method may further include determining, in response to determining that the descaled well fails to satisfy the predetermined criterion, a tubular replacement for the well. The method may further include transmitting, to a control system, a command that implements the tubular replacement.

A remotely operated device for inspecting and/or cleaning a subsea flexible pipe joint comprises a support assembly. In addition, the device comprises a tool positioning assembly coupled to the support assembly. The tool positioning assembly includes a rotating member disposed about a central axis. The tool positioning assembly is rotatable relative to the support assembly about the central axis. Further, the device comprises a cleaning assembly including a cleaning device adapted to clean the flexible pipe joint. The cleaning device is axially moveable relative to the rotating member. Still further, the device comprises a clamping assembly coupled to the support assembly. The clamping assembly has an open position disengaged with the section of the flexible pipe joint and a closed position engaging the section of the flexible pipe joint.

A sucker rod cleaning system includes an inductive heating device, a feed mechanism, a first support and a second support. An electromagnet of the inductive heating device includes a wire coil head that is configured to inductively heat a sucker rod positioned within a heating zone. The feed mechanism is configured to feed a sucker rod through the heating zone in a feed direction. The first support is positioned on an upstream side of the wire coil head, and is configured to support a portion of a sucker rod as it is fed through the heating zone by the feed mechanism. The second support is positioned on a downstream side of the wire coil head, and is configured to support a portion of a sucker rod as it is fed through the heating zone by the feed mechanism.
