ESP Operations – the need for change?
What’s the problem?
− Rigs needed for installation and replacement;
− Replacement delayed due to rig availability;
− High rig cost and lost / deferred production;
− Opportunity cost for using rigs to work-over
failed ESP wells;
− Risk of reduced PI due to kill fluid;
A better way: Slim-line, through tubing, cable
deployed pumps, installed using established
spooling methods and conventional PCE

SpeedDrive - A slim-line centrifugal pump system
made possible by using
Permanent Magnet Motors
Applications:
✓ Contingency ESP(over failed conventional)
✓ Primary ESP
✓ Temporary install:-✓ well kick-starting
✓ for appraisal wells
(operating through w/l PCE)
Delivering:
✓ Rigless, retrofit intervention
✓ Live well workover
✓ Rapid replacement
✓ Improved safety

First (cable) Deployment Test in 2016
Presentation video removed
This first trial was conduced at a
drilling training centre in Oklahoma
The objective was to demonstrate:
• Anchor / latch setting;
• BHA free spools from lubricator;
• RIH
• BHA latching / unlatching
• POOH
Completed under simulated live
well conditions
Exercise completed 5 times
without incident
Trials were a complete success

5 trials completed under live well
conditions with full pressure control:
− No safety incidents, no damage to equipment;
− System self spooled to depth;
− System successfully landed out in anchor
packer;
− Surface termination successfully completed;
− System powered up and fluid confirmed on
surface and;
− Successfully re-connected to the deployment
cable and retrieve to surface under live well
conditions.
− Fully horizontal deployment demonstrated
The full operational life cycle:
Run. Operate. Retrieve.
