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
