Goal of Any Production Method
Reduce the Producing Bottom Hole Pressure to
the minimum pressure, within cost constraints,
to allow the reservoir pressure to push the
fluids and gas to the wellbore.

How Do You Select the Best Artificial Lift Method?
Expected Liquid and Gas Production rates Well Completion Field Experience Field Personnel Technology Level
Best “Average” Production & “Lowest Life-Cycle Cost”Sept. 15 - 18, 2009 2009 Sucker Rod Pumping Workshop

Deciding on Artificial Lift Production Method
• Data you need to reviewHistoric production data – BOPD, BWPD, Mcf/D Production reports Decline curves & IPR/PI curves Swab reports Determine how the well was produced prior to
moving to artificial lift Talk to the Gaugers/Pumpers Production history of other wells in same
formation

Deciding on Artificial Lift Production Method
• Data you need to review (cont.)The wellbore drawing/drilling report Casing size/liners Deviation Study Packers Perforations depth PBTD/Fill depth How Much Rat Hole – RHIYF
Review the prime mover power sources – , casinghead, field gas or electricity

Rod Pump Application
Graph Illustrating the Window of Rod Pump Application
Graph Assumes:• Pumping Unit has the torque and beam to pull the
load• Tubing size is adequate for rod string required• No gas interference

Rod Pump System Design Process
Wellbore
• Casing Size/Tubing Size• Depths and Deviation Study• Packers• Completion: Frac/ Open Hole/ Liners
Production
• Historic Flowing Production – this and other wells• Swab Runs• Intermitted Production Reports• Your Best Guess as to Future Production & Decline
Predictives
• Qrod®• LoadCalC®• RodStar®• SROD®

Rod Pump System Design Process
Pump Size & Type
• Target Production > Pump Size, Stroke Length, & SPM• Pump Fit and Plunger Type• Pump Intake Above or Below the Perforations• Pump Type – Straight API, TSHVR, H-F VSP®• Gas Separator
Rod String Design
• Pumping Unit PPRL and Torque • Straight or Taper• Grade D or High Strength• Sinker Bars – “Always Keep the Rod String in Tension!”• Rod Guides
Pumping Unit
• Stroke Length• Predicted Peak Polished Rod Loads• Predicted Torque requirements• Strokes per Minute

Conclusions
• Every well is different• Understand the production and productivity
– What did it make – How did it make it
• Treat every well as if it is producing gas• Rat Hole Is Your Friend• Generally, Rod Pump will take the well from
flowing to depletion• Be Aware of today’s Schedules for supplies
