-----------------------------A collection of Reservoir Engineering Utilities -----------------------------

This set of functions focuses on those that the author uses often while crafting programming solutions. These are the scripts that are often copy/pasted from previous work - sometimes slightly modified - resulting in a trail of slightly different versions over the years. Some attempt has been made here to make this implementation flexible enough such that it can be relied on as-is going forward.

Includes functions to perform simple calculations including;

• Inflow for oil and gas
• PVT Calculations for oil
• PVT calculation for gas
• Creation of Black Oil Table information
• Creation of layered permeability distribution consistent with a Lorenze heterogeneity factor
• Extract problem cells information from Intesect (IX) print files
• Generation of AQUTAB include file influence functions for use in ECLIPSE
• Creation of Corey and LET relative permeability tables in Eclipse format

Apologies in advance that it is only in oilfield units with no current plans to add multi-unit support.
