Applied Petrophysics (basic)
Peter Betts
5 days
Business context
In the E&P business, integrated petroleum engineering
studies and field development plans are management tools which are
used to maximise economic recovery of hydrocarbons. Petrophysical
engineers fulfil a key role in analysing and interpreting
subsurface reservoir data, which form the basis for reservoir
models. Understanding the methods used in petrophysical analysis,
and the related uncertainty of the results and hence the derived
models is essential knowledge for all E&P technical staff.
Who should attend
Staff in the exploration and production department with no or
limited petrophysical background: petroleum engineers,
seismologists, geologists, reservoir engineers, and drilling
engineers.
Course content
Subjects that are covered are fundamental petrophysical
relations, tool principles, modern interpretation methods and core
measurements. The importance of interaction between seismology,
geology, petrophysics, reservoir engineering and other disciplines
is emphasized and illustrated. The main emphasis during the course
is on practical application rather than extensive discussion around
the theoretical background.
Shorter versions of the basic course lasting two, three or four
days are also available on request. The client can decide in
consultation with the trainer which topics covered in the full five
day version can be dropped in the shortened versions.
Learning, methods and tools
Throughout the course work sessions will be held on PCs using
customise Excel spreadsheets, which illustrate the processing
methods used by commercial petrophysical analysis software. During
the five days, several clastic and carbonate wells will have been
evaluated using quicklook visual methods, as well as fairly
detailed numerical analysis.
