Collection of data with minimal pressure loss in flowing wells

 

Technical Challenge:

Collection of data with minimal pressure loss in flowing wells

Peak Solution:

5 ½-in large bore gauge hanger and SIM running tool

Customer:

National oil company, offshore Malaysia

Well Type:

5 ½-in oil producer (74 degree deviation, 250-330 deg 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-in 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
