Descriptive Lithology Course

Catheart Energy Inc.

Sample cuttings from the Cretaceous Ostracod Zone, Alberta, Canada

As the search for oil and gas becomes more difficult, critical data often overlooked are the cuttings and cores of existing wells. There are millions of boxes of core and cuttings unused and in storage at state geological surveys and private and federal repositories. This course teaches participants a comprehensive and consistent method to extract critical information from this material by describing the lithology and petrography of cuttings and cores using a binocular microscope and a few simple tools. Topics include lithology, accessory minerals, porosity and permeability, color, diagenesis and metasomatism, texture, grain size, framework, etc. Using these techniques these data can then be used for reservoir description, facies mapping, etc. in the search for new oil and gas resources and efficient exploitation of known resources.

Practical applications of concepts and methods for describing rocks are demonstrated through exercises to reinforce key concepts. Participants are expected to independently view and describe a sequence of samples for the final exercise.

Completion of the course should prepare participants for immediate application and utilization of all concepts and techniques for extracting the maximum information from cuttings and cores.

Who should attend:

Geologists in both exploration and production who desire to enhance their ability to get more information from existing sample datasets and describe lithology from cuttings and cores for stratigraphic interpretation, facies mapping and reservoir characterization.

The course is also available as a 2 Day Clastics Course or a 3 Day Carbonates Course.
