PyResToolbox - A collection of Reservoir Engineering Utilities

Overview

pyrestoolbox

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

This is the initial public release, with improvements and additions expected over time. Apologies in advance that it is only in oilfield units with no current plans to add multi-unit support.

  • refactor oil sg equations to func and correct 141.4 -> 141.5 per standard API equation

    refactor oil sg equations to func and correct 141.4 -> 141.5 per standard API equation

    There are 4 places in the source code where the oil/condensate specific gravity is calculated from the API. So I refactored those lines with the general equation near the top of the file.

    def oil_sg(api_value: float) -> float: """ Returns oil specific gravity given API value of oil api_value: API value """ return 141.5 / (api_value+131.5)

    The original 4 places the specific gravity was calculated using 141.4 (assume a typo). Petrowiki API Reference

    Thank you for the repo and I will continue reading the source code!
