H.W. Reid


Course Duration:

One week


Who Should Attend:

This practical seminar is directed at exploration, engineering and drilling personnel concerned with making operation decisions based on DST results of who use DST data in general exploration/exploitation work. It is also for regional geologists who use show maps and pressures in correlation work those looking for missed pay (bypassed pay) in old wells.


Objectives:

This popular course has been presented industry wide for over l6 years in Canada, USA, Scotland, Austria, Australia, India, Indonesia, Thailand, Egypt, Libya, Bolivia, Ecuador, Venezuela, Bahrain, Turkey, Vietnam and Malaysia.

This seminar emphasizes practical application rather than theoretical derivations of computations. The comprehensive course manual contains DST charts from over 60 field examples which can be used for troubleshooting problem DST's later. Participants are encouraged to bring examples from their own work experience.

  • Course is taught with visual aids keyed to the course manual.
  • All material covered in exact order presented in the manual (slowly, clearly, and thoroughly!).
  • This eliminates need for note taking allowing students to concentrate on lectures and discussions.

Content:

  • Equipment fundamentals and pretest planning
  • Basic pressure chart interpretation (qualitative) to identify permeability types - How to recognize depletion of a limited volume reservoir -Differentiation of depletion from 'supercharge'
  • Recognizing mechanical problems, e.g. tool plugging. packer and valve leaks, etc.
  • Pressure gauge and clock malfunctions
  • Quantitative reservoir analysis for Kh, skin, PI, stable AOF, reservoir geometry understanding conflicts between DST and core/log data
  • Missed pay (bypassed production) by identifying formation damage and 'deep' damage
  • Closed chamber (teleflow) tests for deep overpressure or sour gas or tight gas
  • Significance of recoveries of 'oil cut mud' and gas rates of 'tstm' to exploration
  • Making a decision to complete or abandon a wildcat with only marginal DST results
  • Interpreting poorly run old DST's where Horner Analysis & derivative type curves will not yield answers
