Systems and methods presented herein facilitate operation of well-related tools. In certain embodiments, a variety of data (e.g., downhole data and/or surface data) may be collected to enable optimization of operations related to the well-related tools. In certain embodiments, the collected data may be provided as advisory data (e.g., presented to human operators of the well to inform control actions performed by the human operators) and/or used to facilitate automation of downhole processes and/or surface processes (e.g., which may be automatically performed by a computer implemented surface processing system (e.g., a well control system), without intervention from human operators). In certain embodiments, the systems and methods described herein may enhance downhole operations (e.g., milling operations) by improving the efficiency and utilization of data to enable performance optimization and improved resource controls of the downhole operations.

System and methodology for determining appropriate rate of penetration in downhole applications

A technique facilitates precision fluid conveyance and placement to one or more desired locations in a borehole, e.g. a wellbore. According to an embodiment, a material container, e.g. a fluid container, and/or a fluid flow path system may be deployed downhole via coiled tubing. A release system is selectively actuatable to release a specific amount or amounts of material, e.g. treatment fluid, at the one or more desired locations along the borehole. Depending on the application, various discharge mechanisms and/or supply mechanisms may be used in cooperation with the material container and/or fluid flow path system to provide the precision fluid conveyance and placement.

System and method for controlled downhole chemical release

Flow rate pressure control during mill-out operations

System and methodology to identify milling events and performance using torque-thrust curves

A technique facilitates mechanical and electrical connection between components. The components may be coupled mechanically by a threaded engagement and electrically by first and second electrical couplers. The first and second electrical couplers may each have a plurality of electrical contacts oriented for linear engagement. The electrical contacts of the second electrical coupler are mounted on a first portion of the second electrical coupler which is rotatably received by a second portion to enable linear engagement of the electrical contacts while rotating the components relative to each other to form the mechanical connection.

Electrical connection apparatus and method

A technique facilitates an improved operation of a tool, such as a downhole tool. The tool is operated in a manner which provides a dynamic or cyclical loading. The dynamic or cyclical loading of the tool is sampled by a suitable sensing system at a frequency greater than the frequency of the dynamic or cyclical loading to collect detailed data on the dynamic or cyclical loading. The data is used to adjust the tool in a manner which improves operation of the tool. One technique for adjusting the tool is changing the dynamic or cyclical loading of the tool by adjusting the frequency of the dynamic or cyclical loading.

Intervention operations with high rate telemetry

A technique facilitates measuring loads while compensating for the effects of differential pressure. The technique utilizes a load cell comprising a chassis and a sensing element mounted on the chassis. A housing encloses the sensing element in a chamber formed between the chassis and the housing. The housing is connected to the chassis in a manner to transfer loading, e.g. compressive, tensile, and/or torque loading. A pressure compensating piston is positioned within an interior of the chassis and the housing. A plurality of seal points is located in a manner which isolates the sensing element from the effects of differential pressures between the interior and an exterior of the load cell.

Pressure balanced flow through load measurement

A technique for determining conditions downhole in a well, particularly load conditions acting on a well tool, e.g. a bottom hole assembly. The loads acting on a bottom hole assembly or other well tool during a well related operation are measured. Load data is collected and may be transmitted uphole in real time for evaluation at a surface control unit. Based on the load data and other possible data related to the downhole operation, corrective actions can be taken to improve the operation.

System and method for obtaining load measurements in a wellbore

The present invention provides a packer cup system for use inside a wellbore comprising a packer cup and a backup component coupled thereto. In one configuration, the backup component further comprises an angled support member and a rubber ring disposed between the angled support member and the packer cup. The support member is configured to facilitate uniform expansion of the rubber ring.
