Artificial Lift Technologies for Production Optimisation Projects, Facilities and Construction

Bill Lane

Course Outline

Overview

  • The life of the well: natural flow, leveraging well energy, adding energy
  • When is artificial lift needed?
  • Physical choices for how to lift liquids to surface
  • Lift technologies characteristics: plunger lift, foam lift, gas lift, rod lift, PCP, ESP, hydraulic lift
  • Production optimisation as a process

Reciprocating Rod Lift

  • Operating principles
  • Application limits
  • Components: rod pumps, rod strings (sucker rods, continuous rods), pumping units, VSDs, dynamometer cards, gas anchors

Progressing Cavity Pumps

  • Operating principles
  • Application limits
  • Components: pumps; drive-heads
    • Special configurations: charge/recirculation pumps, bottom-drive pumps (ESPCP), elastomerless (metal-to-metal)

Gas Lift

  • Operating principles: continuous flow and intermittent flow
  • Application limits
  • Components: mandrels; valves; running/retrieving tools
  • Optimizing gas lift

Electric Submersible Pumps

  • Operating principles
  • Application limits
  • Components: pumps (radial flow, mixed flow, multiphase), gas separators, motor seals, motors, power cable, surface equipment, complex configurations

Hydraulic Lift

  • Jet pumps
    • Operating principles
    • Application limits
    • Special applications: frac flow-back, formation powered pumps
  • Hydraulic piston pumps
    • Operating principles
    • Application limits

Plunger lift

  • Operating principles
  • Application limits
  • Components: plungers (pad, brush, solid ring, bypass), downhole assembly, surface lubricator, controllers
  • Special configurations: progressive (multiple) plunger systems

Gas Well Deliquification

  • Flow regimes
  • Velocity strings and dead strings
  • Surfactant/foam
  • Capillary systems
    • Special applications: long producing intervals, extended reach gas lift (beyond a packer)

Class exercise: 3 application examples for the class to select appropriate lift systems

Emerging Technologies: technologies on the horizon
