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 summarizes Degeconek tools with their benefits:

Stationary Noise Tool (SNT) is a passive acoustic tool (real-time SRO) embedded with carefully designed set of sensor elements to achieve a wideband frequency response which is highly sensitive from 40Hz and 60kHz and high resolution temperature sensor which is a valuable compliment to the spectral noise measurements used to delineate and infer:

  • Detect leaks in the wellbore
  • Crossflow and flow behind pipe/casing evaluation
  • Flow profiling combined with PL tools
  • Fracture and matrix bypass detection
  • Active flow units behind casing in producers
  • Location of open perforations
  • Diagnose gas breakthrough

 

Acoustic Leak Flow Analyzer (ALFA) is a passive acoustic tool (memory) embedded with high precision temperature tool used to carry out various well diagnostic studies including Well Integrity Evaluation, Production Performance and Reservoir Monitoring.

  • Detect the source of sustained annular pressure / leaks in the wellbore
  • Diagnose gas or water breakthrough
  • Reservoir Characterization and Formation Evaluation
  • Borehole and Reservoir Performance
  • Location of open perforations
  • Identification of active flow zones behind pipes
  • Identification of channeling behind pipes

 

Magnetic Thickness Detector (MTD) is an electromagnetic corrosion measuring instrument primarily run through tubing with the unique ability to simultaneously inspect tubing and the casings behind (memory / SRO) used to;

  • Investigate casing/tubing integrity due to metal losses (both internal & external)
  • Evaluate tubing and casing thickness
  • Can be correlated with PLT to explain poor productivity or injectivity.

 

Multi-Finger Caliper (MFC) is used for the following

  • Investigate any change in casing/tubing internal diameter
  • Evaluate any internal tubing and casing corrosion, erosion, wear, bending, buckling, holes and other defects with high accuracy
  • Can be correlated with PLT to explain poor productivity or injectivity

 

Radial Bond Log (RBL) used for the following:

  • Investigate hydraulic isolation between producing and non-producing zones
  • Evaluate quality of cement bonding
  • Identification of top of cement
  • Identification of channels and intervals

 

PLT Tool

  • Evaluate borehole multiphase profile
  • Evaluate flow contribution from the open perforation
