SUMMARY. Gas presence in the pumping zone causes problems such as gas lock, gas pound, and gas interference which cost companies' time, money and resources. Reduced pump efficiencies inspired our research team in developing an innovative design for gas separation that diverts gas from entering the pump intake. Consequently, reducing pump failures maximized pump efficiency. See Video here.
Uses, Operation, Design Considerations and Load Ratings of On-Off ToolRicky Roderick, Don-Nan Pump & Supply Company

SUMMARY. The scope of this paper includes a brief introduction about On-Off tool, design and construction, their applications, operational procedures, and general load carrying capabilities. The paper discusses some advantages gained by installing an On-Of tool such as, the ability to repair or replace the rod string without unseating the pump, the ability to break the sucker rod string just above the pump eliminating stripping job and the ability to run oversized tubing pumps.

Extending Downhole Pump Life Using New TechnologyG.M. Muth, SPE, Muth Pump Company LLC, and T.M. Walker, SPE, Evans, Frey and Walker

SUMMARY. "Sand, whether formation sand or frac sand, is produced along with hydrocarbons and water from many wells. This sand can accelerate wear of the plunger and pump barrel, and can also cause the plunger to stick in the barrel. These problems may result in frequent pulling jobs and expensive pump repair costs. The Farr plunger, a newly designed pump plunger and pull rod, has been tested during this past year in numerous oil fields in California. These tests indicate that the Farr plunger has the potential to reduce the pump wear and plunger sticking problems caused by sand production. This paper describes this new design, and the initial results of the field trials." As the largest distributor of FarrPlungers, Don-Nan encourages all customers to contact us from anywhere in the world.

SUMMARY. From the selection process to installation and continued maintenance, the Tubing Anchor Catcher (TAC) is one of the most important tools in achieving efficient pumping operation. The upstream oil and gas sector continues to evolve with new methods morphed from old methods as it pertains to artificial lift systems. While the people and parts continue to change, understanding the basic, yet important, aspects of TACs with relation to their applications, operational procedures, and tubing stretch is necessary. In covering the basics and importance of the TAC, the scope of this paper will expand on tubing stretch calculations, shear values, drag spring usage, troubleshooting, and other installation techniques.
