Artificial Lift

With the data collected over many years, we can show how we have improved the gas lift valve tear down process, and how that data collected from this process has increased longevity of wells in each, individual area. While following the API Standards of gas lift valve expectancies, both in initial installs as well as reporting once valves are pulled, data is paramount. The ability to provide...

Unconventional reservoirs bring new challenges for Electrical Submersible Pump (ESP) Systems, such as rapid decline and high gas production. As these conditions can add obstacles to the operators to efficiently produce the wells, the industry is always looking for opportunities to improve ESP performance. This study analyzes the performance of some successful ESP Applications installed to produce...

The efficiency of most artificial lift systems is reduced significantly whenever the tubing and the annulus are in communication due to the presence of unwanted holes or leaks developed in some of the hardware used in the installation. Detection of the problem from analysis production records must be followed with field tests that verify the diagnostic before proceeding with repair operations.

There is a need in the industry for a predictive program that can mimic the vast combinations of downhole pump conditions that are found in sucker rod pumped wells. In this paper, we introduce a software that is capable of showing the all of the basic downhole pump conditions, as well as combinations of these conditions in both vertical and deviated wells. The software can show the ideal downhole...

Black Mamba Rod Lift debuted in 2019, shipping its first Complete Rod Control sucker rods in Fall of 2020. Its use has expanded across the globe in a variety of wells and drill styles, meeting various needs of operators. In 2022, Chevron began piloting Black Mamba’s Complete Rod Control designs and product in complex, problematic wells. Alternate solutions were also deployed simultaneously in...

When operating rod pumps, it is important to match the volume displaced by the pump to the inflow from the reservoir. By doing so, downhole pressure is minimized, thus maximizing production, while keeping mechanical damage and power consumption to a minimum. Various devices such as time clocks, pump-off controllers or variable frequency drives have been adopted in the industry to achieve this goal...

Production engineers rely upon a variety of data streams from the field to optimize production and maintain safe, environmentally responsible operations; without the reliable collection of this information, we cannot do our jobs. Given the challenges of operating assets spread over vast areas and the inadequacies of workflows relying upon manual measurements and communication, automated data...

This paper presents new research methods, designs, and field testing of a new type of mechanical gas separator for electric submersible pumping (ESP) systems that increases the operating flow range and separation efficiency performance, while decreasing erosion problems and improving reliability. 

A state-of-the-art test system for measuring and understanding the internal workings of two-phase...

The objective of this paper is to present oil and gas industry the advancement and improvement of the Baker Hughes ESP phase system on wells with relatively high GLR, moderate water cut, and suggest considering the presented design system in comparable wells for an extended run-life. Paper presents run-life analysis and comparison of a conventional design versus the phase system in terms of power...

Continuous sucker rod had been used for many years in sucker rod pump applications. However, several challenges have limited its acceptance in the past. The availability of service equipment, welding methodology, and selection of metallurgy all contributed to premature failures and operator frustration with the timeliness of installation and repairs.

A new approach to implementing continuous rod...
