Breakout SessionSurface and Downhole Equipment Specs

How can performance be improved by product selection?

OR

Can I purchase a perfect pumping system?

Operating Challenges:

Corrosion Erosion

Sand Gas

CO2 H2S

High 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

  • Servicecompanies 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 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

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

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?
