Petroleum Related Rock Mechanics, 2nd Edition

This is a list of most of the symbols used in this book. General mathematical symbols, some basic symbols such as x, r, etc., and a few symbols used only where they are defined are not included.
The order is alphabetical, in the order symbols, script letters, Greek letters and Latin letters. Capital letters precede lowercase letters. Where applicable, the list shows the number of the first equation where a symbol is used.
