This is a case study designed to confirm that high frequency, high resolution pressure data measured at the wellhead of a pump jack well can be used to evaluate and optimize the performance of the downhole pump.
Project Goal and Overview – Gather true measured data in both deviated & horizontal rod-pumped wells, Plot actual downhole load & position: dynagraph cards, Provide that measured downhole data to industry for use in developing new algorithms, Improve our understanding of side loads, bending, friction, damping, and other factors resulting from well deviation.
Gas interference in downhole oilfield pumps is an old and well-known problem. Horizontal wellbore topology and construction exasperates this problem. Artificially lifting an oil and gas well involves two discrete state-variable spaces: the pumping system and backside multiphase flow. While positive strides have been made around optimizing the pumping system state-space, optimization of that system […]
Sucker rod pumping commonly requires the tubing string assembly to be secured to the casing downhole near the pump to prevent tubing movement. Tubing movement can undesirably reduce downhole pump efficiency and result in premature failure of the tubing string, casing or sucker rods due to mechanical wear/fatigue. Downhole tubing anchors are used for this […]
As many as 10% of Laramie Energy, LLC’s wells were non‐producing or under‐producing due to deep‐set tubing or mechanical restrictions in tubing or casing. A program of evaluating existing completions followed by tubing perforation and reestablishment of plunger lift was undertaken to restore economically viability to these wells.
One of the benefits of utilizing a Sucker Rod Pump for artificially lifted oil and gas wells is that they can achieve total drawdown of the casing fluid above the downhole pump. This allows for the pump to maximize the production of the well by minimizing the back pressure on the reservoir caused by the […]
Today an upstream engineer has to understand the running condition of every well he is in charge of in order to optimize production, usually by adjusting various setpoints. Typically he will use data recorded by a pump-off controller (POC), fluid level shots, etc. as well as often coupling this wellhead-level data with intermittent information from […]
Artificial lift digitization generates large amounts of data used by operators for surveillance and for improving the function and health of lift equipment, surface facilities, wellbore, and possibly reservoir. As oil and gas companies move towards digital transformation, ML/AI application in artificial lift space is considered a ‘low-hanging’ fruit. However, there is a considerable FUD […]
There’s been a dilemma in the oil industry for years concerning the sharing of data, knowledge and expertise. Should we share or keep it close and possibly have an advantage over our competitors? Is it worth the time and effort required for presentations and related approvals or is it a waste of time personally and […]
