Well Integrity & Reservoir Surveillance

Our state-of-the-art High Resolution cased-hole technology helps to deliver the best form
of diagnostics for proper Well Integrity and Reservoir Management.

Well Integrity & Reservoir Surveillance

Degeconek has evolved to be an indigenous household name in the area of well integrity and reservoir surveillance. We use unique state-of-the-art High Resolution cased-hole technology, software and interpretation techniques to deliver the best form of Well and Reservoir Management as well as Asset Optimization to clients.

We have a leading edge with the benefits our tools offer in the areas of; enhanced production, increased ultimate recovery, improved Reservoir Development strategies as well as increased efficiency of pressure maintenance solutions.

We are experts in designing and conducting integrated production optimization programmes including extensive borehole logging, comprehensive reservoir studies and simulations, production/injection pattern revision using newly drilled and converted wells and production/injection optimization for individual wells through recompletion and reservoir treatment.

The following summarize Degeconek tools with their benefits:

  • Array Noise Tool (ANT) is a noise tool (memory/SRO) used to delineate and infer:
    • Source of high annular pressure, especially due to gas percolation.
    • Gas breakthrough
    • Detect leaks in the wellbore
    • Channeling behind casing
    • Capture zones of mud circulation losses
    • Active flow units behind casing in producers
    • Active injection units behind casing.
    • Location of open perforations
  • Acoustic Leak Flow Analyzer (ALFA) is a noise tool (memory) used to verify:
    • Source of high annular pressure, especially due to gas percolation.
    • Gas breakthrough
    • Detect leaks in the wellbore
    • Channeling behind casing
    • Capture zones of mud circulation losses
    • Active flow units behind casing in producers
