** *** Two-Phase Flow through Porous Media*
Since Fall 2001, I have been distributing copies of * Two-Phase Flow through Porous Media* as an 8.5" x 11" manuscript with a plastic spiral binding. This text emphasizes the fundamentals of two-phase flow and applications of those fundamentals to assessing quality of data from capillary pressure and relative permeability tests. It is an excellent introduction to reservoir engineering. A CD of software demos written as spreadsheets and Visual Basic modules for Excel comes with the text.
