PowerTrac® PRIMETM conveyance technology reduces tractor conveyance time by 50% on a North Sea P&A operation

 

  • Total tractored distance – 12,218ft (3,724m)
  • Tractor speeds reached up to 111ft/min (34m/min)

CHALLENGE

In preparation for a permanent Plug and Abandonment operation the client first required to secure the well using a deep-set plug, followed by cutting the tubing above the production packer to enable tubing retrieval. The well had a maximum deviation of 90 degrees. With P&A cost reductions a focus for the client, operational time saving was a key priority.

 

solution

Altus Intervention recommended its new electrohydraulic PowerTrac® PRIMETM tractor to execute the tractor conveyance required for these eline operations. With over 12,000ft (3700m) of total tractoring required, the high conveyance speeds and intelligent in-well speed/force optimization capabilities provided by the PowerTrac® PRIMETM tractor, offered material time savings.

 

RESULTS

On the first run the PowerTrac® PRIMETM tractor conveyed the plug a distance of 7,266ft (2,215m) achieving a maximum tractor speed of 107ft/min (32m/min) with an average of 91ft/min (28m/min).  This was followed by the cutter run, for which similarly impressive maximum and average tractor speeds were achieved. The average conveyance speed resulted in a 50% reduction of tractor conveyance time when compared to conventional tractor conveyance technology.
