Course Description
This course provides an introduction to the basic skills and techniques required to generate reliable subsurface maps and volumetric estimates by hand from well and seismic data. Although subsurface interpretation work and contouring is now largely done using computers it remains essential for early career geoscientists and petroleum engineers to understand basic mapping and volumetric concepts and retain control of the critical decisions involved in the process.

A five-day classroom course, comprising lectures, worked exercises and discussions, with at least half of the time devoted to worked examples. Participants will make a variety of hand-contoured maps from both well and seismic data, and understand their significance for estimating volumes of hydrocarbons in place in both exploration and production contexts.

Participants will learn to:
•	Undertake hand-contouring of posted well and seismic data for structural horizon tops, thicknesses and 
        reservoir properties.
•	Illustrate fault geometries in section and map view and understand how faults and horizons intersect.
•	Discuss the use and abuse of statistics and geostatistics in computer mapping.
•	Appreciate that maps should look good as well as being technically good
•	Understand the principles of seismic acquisition, processing and interpretation.
•	Understand the principles of depth conversion and calculate an average velocity map from well tops and 
        seismic times.
•	Pick formation tops, correlate wireline logs and generate cross sections using good geological principles.
•	Understand the basics of 'quick look' petrophysical analysis.
•	Analyse subsurface pressure data to constrain fluid contacts and determine lateral and vertical connectivity 
        of reservoir fluids.
•	Determine volumetric estimates of hydrocarbons in-place using a variety of methods, including assessments 
        of uncertainty.

This course is offered by Nautilus (www.nautilusworld.com), a PEICE affiliated company and the world leader in Geosciences Training services.

A complete set of course materials and lunches are included.
