Course Overview -— Techniques for Visual Porosity-Permeability Estimates in Rocks
COURSE OVERVIEW
This two-day course is intended to introduce through lectures and exercises the concepts and techniques needed for making visual estimates of porosity and permeability in well cuttings. The session includes scientific background but emphasizes recognition criteria and their application to clastics and carbonate rocks. Practical application highlights an innovative use of Archie's and Lucia's classification. The course requires delegates bring a binocular microscope and one hundred (100) feet of cuttings. It includes a training manual.
DESIGNED FOR
Exploration, Production, and Well site Geologists
LEARNING OBJECTIVES
Upon completion of this course participants should be able to:
use the visual appearance of carbonates and clastics to estimate the total porosity in cuttings or other rock samples
establish recognition criteria for estimating the visible porosity in rock samples
estimate permeability to within an order of magnitude using Lucia's chart
describe the most important physical and chemical controls on porosity development in clastics and carbonates
describe the most important attributes that influence permeability in rock samples
classify terrigenous clastic pore types according to Schmidt
classify carbonate pore types according to both Lucia and Choquett and Pray
PREREQUISITES
Basic Carbonates for Exploration, Basic Clastics for Exploration or equivalent to all the above courses
