Drillstem Test (DST) Interpretation Seminar for Engineers & Geologists
NOW 3 1/2 Day Workshop
Hugh W. Reid, P.Geol.
Phil Esslinger, P.Geol.
Who Should Attend
This three and a half day practical
seminar is directed at exploration, engineering and drilling personnel
concerned with making operational decisions based on DST results or who
use DST data in general exploration/exploitation work. It is very useful
for geologists evaluating old wells with DSTs for land acquisition.
taken with class discussions of numerous field examples.
are encouraged to bring examples from their own work experience to
Emphasis is placed
on practical application rather than theoretical derivations of computations.
Method of Instruction
Course is taught
with visual aids keyed to the course manual.
All material covered
in exact order presented in the course manual (slowly, clearly, and thoroughly).
This eliminates the need for note taking which allows students to concentrate
on lectures and discussions.
Manuals / Textbooks
Course manual contains
over 60 examples of DST charts that can be used for trouble shooting problem
DSTs later. It is a permanent reference source.
To avoid the problem
of attendees forgetting procedures taught at the course, all techniques
are given in cookbook format.
The course is designed
to provide participants with information not normally encountered in routine
service company training seminars and to impart analytical and interpretive
skills gained by the instructor in over 25 years of experience.
By the end of the
course, students should be able to accomplish the following:
- diagnose damage,
depletion, and mechanical malfunctions, such as tool plugging
- determine permeability
and forecast the stable flow rate if the well is completed
- understand why
data from cores and logs often conflict with DST data
- make more sense
of DST results printed in PIX well cards and field reports
- make a decision
as to whether to complete or abandon a wildcat with only marginal DST
- appreciate where
recoveries of "oil cut mud" and gas rates of "TSTM"
may be significant from an exploration standpoint
- identify long
narrow reservoirs (such as channel sands) from DST pressure behaviour
- design DSTs which
preserve secrecy where competitors control adjacent land blocks
- estimate the time
until a well stabilizes
- fully understand
closed chamber DSTs
Comments from Past
"This course will easily pay for itself in identifying opportunities (one of which has already been identified during the course)."
Garth Stotts, Res. Engineer
E.O.G. Resources, Calgary
"Great ways to analyze wells without spending too much time or detailed work (unless it is necessary)."
Jason Collins, Exploitation Eng.
Blaze Energy, Calgary
"Course will be most helpful in evaluating land sales as well as up hole potential."
Cindy Robinson, Geologist
"This was the most practical, well prepared course I have attended in the last 10 years."
Gary Finnis, Reservoir Evaluation Eng.
