1. Breakout Session Surface and Downhole Equipment Specs How can performance be improved by product selection? OR Can I purchase a perfect pumping system?

2. Surface and Downhole Equipment Specs Operating Challenges: CorrosionErosion SandGas CO 2 H 2 S High temperaturesWellbore deviation Low volumeHigh volume High loads Surface height restrictions

3. Surface and Downhole Equipment Specs Industry experts: –Danny Love, Weatherford –Russell Stevens, Norris Rods –Bennie Williams, Harbison-Fischer Pumps –Tom Van Akkeren, Consultant Former production company engineer

4. Surface and Downhole Equipment Specs Service companies and manufacturers CAN be your friends They are very knowledgeable about their products All their time is spent is support of their product They MAY NOT know all your problems and your company’s drivers

5. Surface and Downhole Equipment Specs Surface Pumping Units Fluid requirements are highest priority Restrictions must be considered Conventional units about 85% of total Modified geometries Long stroke Low profile and portable

6. Surface and Downhole Equipment Specs Rods Various loading capabilities No rods are corrosion resistant –You can’t afford one that would be –Need a good chemical control program 1 ¼” rods are being constructed for high load application Corod use in US limited by unit availability

7. Surface and Downhole Equipment Specs Downhole Pumps Challenges: corrosion, abrasion, high pressure differentials Solutions: metallurgy, coatings, configurations Pressure actuated pumps may create compression in the rod string JASN failures can be reduced by coatings, liners or pull tube discharge

8. Surface and Downhole Equipment Specs Discussion 2 oil patches –Well run –Look over the fence design Who designs pumping systems? –Company man or suppliers? Who looks at more options? Is enough data provided? Is it correct? Suppliers need feedback on performance Do we need surface readout downhole gauges?
