CWLS07SC Using Ancient Logs To Find By-Passed Pay


This semi-quantitative course covers topics needed to calculate shale volume, porosity, water saturation, and permeability from older (pre 1962) open and cased hole well logs. Integration and calibration to modern logs, cores, tests, and production data are stressed. The best place to find by-passed pay is on older logs - find out how to do it here.

  • Basic tool theory – ES logs (64"/16" normal), laterologs, induction, SP, micrologs, sonic, density, neutron, GR.  
  • Focusing, or lack of it, on older log suites. 
  • Common displays of older logs and how to identify each curve.
  • How to read older logs (e.g. bed boundaries, which log curve is best to use).
  • How do the older measurements compare to current measurements, how have these measurements evolved over time – direct comparisons.
  • How much information can be read from older logs (porosity, perm. hydrocarbon  indicators, bypassed pay),
  • Limitations, common pitfalls of older logs (borehole condition. mud system, invasion, mud cake effects).
  • Quality control and troubleshooting on older logs.
  • “Rule of Thumb” analysis techniques to help identify hydrocarbons – carbonates and clastics..
  • Using core data, local knowledge, modern logs in offset wells to calibrate results.

Beginner to Intermediate, calculator required.

BENEFITS:

  • understand what older logs really measured
    understand uses and limitations of older logs
    understand the rock/fluid model for log analysis
  • provides step-by-step procedures for analysis of older logs
  • provides "computer ready" mathematics
  • gives insight into rock quality versus well performance
  • answer oriented results, with quality control guidelines
  • client specific examples can be added
  • permanent reference material
