HOW TO READ THIS MODEL

The system, explained.

A progressing-cavity pump uses a helical rotor within a stator to move produced fluid through successive cavities. SLB describes this artificial-lift role and its connection to a drive. This original horizontal display makes the component relationship visible: an open intake boundary, complete steel housing, independently contoured stator liner, eccentric rotor, an annular discharge cue and a static rod extension. The gold rotor is a closed solid mesh; the blue liner has inner and outer surfaces. The illustrative geometry leaves a gap and does not mesh, rotate or displace fluid. The poster alone sections the facing housing and liner; the browser model retains both complete surfaces. It is a component lesson, not a depiction of a well completion.

Model scope and limits

Original 31-part static component scene. Two end plates have central and eight perimeter holes each, four display feet have actual bores, and both axial boundary sleeves are open. Horizontal display orientation is for visual reading. The stator shape, rotor path, gap, colours, material labels and component count are invented. No selected elastomer, wear or thermal allowance, drive or rod-string design, fluid properties, gas/solids response, sealed progressing cavities, actual rotation, displacement, capacity, pressure, torque, efficiency, safe operation or service qualification is demonstrated. Technical and rights review remain pending.

GUIDED COMPONENT STUDY

Trace the system.

Read each explanation, then focus its component in the explorer. This is a learning route through the model, with no operating or maintenance sequence.

  1. Find the arriving fluid boundary

    The left axial sleeve is open. It marks a possible intake location, not a selected screen or well completion.

  2. Inspect the complete housing

    The browser model retains both housing surfaces and open ends. The poster alone removes its facing half.

  3. Examine the stator liner

    The blue liner has an original contoured inner surface and separate outer wall. Its profile is not a chosen elastomer or manufactured stator.

  4. Compare the eccentric rotor

    The gold solid mesh follows a helical centreline inside the liner. It remains still and does not form tested sealed cavities.

  5. Read the empty space cautiously

    A slender open marker helps locate a space between the two teaching surfaces. It is not fluid, a measured displacement volume or a pressure stage.

  6. Look through an end plate

    One central and eight perimeter openings are real in this independent plate. Their invented pattern supplies no rated joint.

  7. Follow the opposite boundary

    The blue sleeve points to a destination beyond the stator, around the rod cue. It does not demonstrate an actual discharge or completion.

  8. Identify the drive role

    A separate static rod cue locates a possible drive connection. It has no motion, torque or surface-drive assembly.

  9. Keep the coupling conceptual

    The silver envelope is a location marker. It does not provide a compatible joint, fit or safe assembly instruction.

  10. Check a display support

    The stand and bored foot support the display. They are not downhole hardware or a structural design.
