Sucker Rod Pump

For decades sucker rod pump artificially lifted wells have used devices called pump off controllers (POC) to match the pumping unit’s runtime to the available reservoir production by idling the well for a set time where variable frequencies drives are not available. In doing this the POC allows the well to enter a set period of downtime when the downhole pump fillage is incomplete to avoid...

Production performance monitoring has existed in Rod Lift Artificial Lift for decades, however there has lacked any action based on performance parameters. The Total Production Real Time (TPRT) Monitoring System incorporates data acquisition with artificial intelligence and automation to provide safer production operations for personnel and environment. TPRT collects live production data at...

Black Mamba Rod Lift’s helical centralizer stabilizes the rod string during pumping chaos. Chaos is understood as sucker rod buckling and negative loading (compression), which is impossible to eliminate in beam lift wells. The source of compression is often from nature (gas interference, fluid pound, gas pound) but can be operator induced (seating the pump, pump tagging), or compression as part of...

With the increase in the number of horizontal wells drilled in the past 15 years, the technology for predicting downhole conditions and troubleshooting problem wells has not kept up with the increased complexity of these deeper and deviated wellbores. The systems in use are no longer accurate or sensitive enough to determine what is causing the problem(s) resulting in shorter meantime between...

Surface coatings are commonly used in many industries including oil and gas; with the aim of hardening the part surfaces to improve wear resistance without compromising the corrosion resistance -or even improve when applicable. Sucker rod pumps employ several parts with coated surfaces as well, including the pump barrels. Both standardized surface modifications and specialty applications for pump...

The use of martensitic alloys in sucker rod applications has several significant advantages over ferritic-pearlitic alloys. Processing differences in making the different microstructures will be discussed, along with the resulting property and performance differences. An evaluation of the guidelines for optimal strength in various corrosive environments will be provided. Studies on the fatigue...

A revolutionary packer-type gas separator was designed to improve gas separation efficiency downhole. A deep analysis of gas separation methods was done to better understand the nature of the process and to design a tool that could generate enhanced conditions for the gas separation phenomenon. During the research stages where data from Permian fields were analyzed to develop this new design of...

In a reciprocating rod lift application, production tubing failure due to metal-to-metal contact with sucker rod couplings is a common problem in the highly deviated sections of the tubing string. The coupling is forced to be the point of contact against the tubing wall, which causes high friction and excessive tubing wear during the reciprocating motion. This excessive tubing wear typically leads...

Data from fluid level, dynamometer, pressure, and motor power measurements were acquired by a standalone programmable monitoring system that uses internet and cellphone communication with the Cloud for remote monitoring of well performance. The system named Remote Asset Monitoring or RAM is described in detail in this paper that presents results from the tests that lasted several weeks, beginning...

Data from acoustic fluid level and surface pressure measurements were acquired by a standalone programmable monitoring system that uses internet and cellphone communication with the Cloud for remote monitoring of pressure transient well performance. The system named Remote Asset Monitoring or RAM is described in detail in this paper that presents results from tests that lasted several weeks...
