Case Study 2

Technical Challenge:
Collection of data with minimal pressure loss in flowing wells

Peak Solution:
5 ½” Large Bore Gauge Hanger and SIM Running Tool

Customer:
National Oil Company, Offshore Malaysia

Well Type:
5 ½” oil producer (74deg deviation, 250-330deg F)

The Challenge:
A programmed platform was scheduled, providing an ideal opportunity to conduct valuable data acquisition operations. Six wells across the field were strategically selected for pressure transient analysis.

Considerations:
The campaign offered some difficult working conditions; logistically and operationally. The following key requirements and concerns were highlighted by the Customer:

  • Pinpoint data acquisition
  • Flow through capability
  • Restricted rig-up height
  • Heightened safety concerns with use of explosives and nitrogen
  • Temperature limits on two of the six wells
  • POB capacity

Summary:

  • Six 5 ½” Large Bore Gauge Hangers set on slickline at varying depths
  • Three gauges were connected to each Gauge Hanger
  • All Gauge Hangers successfully set for approximately four weeks duration
  • All Gauge Hangers successfully recovered on standard GS
  • All data recovered from Gauges

Value to Customer:

  • Valuable data recovered for pressure transient analysis
  • Zero NPT
  • Zero harm to personnel
  • Significant cost savings
