(2023031) Autonomous Stuffing Box - Recent Developments and Field Test Results

An ongoing challenge for industry is the maintenance of stuffing boxes used in rod pump wellhead applications. This important component is the primary interface between the well and the environment and the correct functioning of this system is crucial for operators. Traditionally, the maintenance and adjustment of these devices has been performed manually, with field operators visiting wellsite daily to inspect, adjust and maintain the components.

In 2021 an initiative to automate this maintenance process was initiated. Early field test data was acquired and designs for new equipment developed, along with appropriate control systems. Various new elements of the system have recently been deployed into field operations and results obtained. The data sources are from multiple fields and operations, acquired under varying environmental conditions.

This paper will present the latest data and designs, along with results from the new field test data. Analysis will be presented that gives insight into how the systems can be further developed and refined.
