Abstract

A liner hanger, packer, or other joint is connected to and near the top of a liner being deployed. One side of a clutch is formed on the liner hanger, packer, or other joint by fingers that protrude inwardly from and are preferably integral to a shroud. The other side of the clutch is formed on a running tool. The shroud can provide support to the fingers and limit their bending in the inward direction in cases where they are accidentally impacted. The shroud can also shield the base casing from the flow of fracking fluid and limit its erosion. The surfaces delimiting the top of the fingers and the bottom of the spaces between the fingers can be oriented so as to smoothly direct fluid flow toward the inner bore of the liner without generating significant turbulence.

Abstract

Described herein are systems and techniques for monitoring substances that are injected into an Earth formation whether that be CO2 from a carbon capture and storage (CCS) process, or water or steam injected for an enhanced oil recovery (EOR) process. Components located on an outside of a wellbore casing may be electrically isolated from components located on the inside of the wellbore casing. Data and/or power may be transferred through the wellbore casing wirelessly in order to increase the reliability of a data collection system because the need for wires to be placed on the outside surface of a wellbore casing is eliminated. The components located on the outside of the casing may receive electromagnetic (EM) or transmit EM fields as part of a system that collects data about substances that are injected into Earth formations during a CCS or EOR process.

Abstract

Typical borehole monitoring systems produce a visual component that can be used by a user to monitor borehole operations. It can be difficult for a user to monitor more than one monitoring system, where different skills are used, different output formats can be used, and where users can be distracted or miss an interpretation. A borehole operation analyzer can use as inputs the other borehole monitoring systems output visuals (such as images, graphs, charts, spreadsheets, or other types of visuals) to produce an improved monitoring and generate an analysis using two or more monitoring systems. The processes can generate messages, alerts, warnings, recommendations, or directions to other borehole systems using specified thresholds. Users can act using the results, other borehole systems can use the results as inputs into their processing systems, or borehole systems can be directed to take action using the results from the analysis.

Abstract

Aspects of the subject technology relate to systems, methods, and computer-readable media for identifying petrophysical parameters of a wellbore or wellbore derived samples. An elastomeric sensing device may be used to collect data from a surface of a sample. This may include pressing a sensing portion of the elastomeric sensing device onto a selected surface of the sample. Images of the surface of the sample may be acquired, and a combination of filtering techniques and segmentation techniques may be used to identify the sizes of pores or pore aspect ratios of the sample when the petrophysical parameters of the wellbore or the wellbore derived samples are identified.

In an example, the magnetic cleanout tool is coupled to a completion string below a well tool to magnetically attract ferromagnetic debris ahead of the well tool as the completion string advances downhole. The magnetic cleanout tool includes an annular magnet carrier defining an array of magnet receptacles that receive a corresponding plurality of magnets. Ferromagnetic debris is thereby removed ahead of the well tool as the completion string advances downhole to keep the debris away from the well tool.

Abstract

Typical borehole monitoring systems produce a visual component that can be used by a user to monitor borehole operations. It can be difficult for a user to monitor more than one monitoring system, where different skills are used, different output formats can be used, and where users can be distracted or miss an interpretation. A borehole operation analyzer can use as inputs the other borehole monitoring systems output visuals (such as images, graphs, charts, spreadsheets, or other types of visuals) to produce an improved monitoring and generate an analysis using two or more monitoring systems. The processes can generate messages, alerts, warnings, recommendations, or directions to other borehole systems using specified thresholds. Users can act using the results, other borehole systems can use the results as inputs into their processing systems, or borehole systems can be directed to take action using the results from the analysis,

A method for treating scale includes feeding a pre-flush fluid into a portion of a subterranean formation via a wellbore. The method includes feeding an inhibitor main pill fluid into the portion of the subterranean formation via the wellbore after the pre-flush fluid, wherein the inhibitor main pill fluid comprises a scale inhibitor. The method includes feeding an overflush fluid into the portion of the subterranean formation via the wellbore after the inhibitor main pill fluid, wherein the overflush fluid comprises one or more surfactant. The method includes shutting in the pre-flush fluid, the inhibitor main pill fluid, and the overflush fluid within the portion of the subterranean formation for a pre-determined period of time.

Abstract

Check valves with suction retainers and methods of using the same. A check valve has a valve housing with a flow path. A restriction in the flow path narrows the diameter of the flow path. A blocking member in the flow path moves in the flow path to block the restriction and at least partially seal the flow path. A suction retainer has a longitudinal axis. The suction retainer is in the flow path. The suction retainer has a central component disposed on the longitudinal axis with a throughbore along the longitudinal axis. The suction diverts flow to an exterior of the central component such that the fluid flows around the central component to reduce pressure in the throughbore. The reduction in pressure retains the blocking member on the retaining end.
