Surface and Downhole Equipment Specs
  • 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 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

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?
