Breakout Session Surface and Downhole Equipment Specs How

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

Surface and Downhole Equipment Specs Operating Challenges: Corrosion Erosion Sand Gas CO 2 H 2 S High temperatures Wellbore deviation Low volume High loads Surface height restrictions

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

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

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

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

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

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?
