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

CO2 H2SHigh temperatures Wellbore deviation

Low volume High 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

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?
