Petroleum-Engineer-Toolbox

Useful tools that can be used to solve different kind of problems faced by the production or petroleum engineer.

Inside the toolbox:

temperature.py

This module define the class temperature. Easy engineer approach about how to deal with a temperature. Instead of always converting the values, you just need to call the unit which is an attribute. Set available:

• 'c': Celsius
• 'f': Fahrenheit
• 'r': Rankine
• 'k': Kelvin

Example:

t = temperature(15,'c')  # (str) 'c' standing for celsius
t.f()                    # (float) return the value converted into Fahrenheit.

pressure.py

This module define the class pressure. Easy engineer approach about how to deal with a pressure and different scale changes. Instead of always converting the values, you just need to call the unit which is an attribute. Set available: ['psi','bar','pa','atm','hPa','inchW','inchM'] in absolut and gage.

Example:

p = pressure(14.5,'psi') # the builder considers the value in gage 'g' if not specified, you can also write:
p = pressure(14.5,'psi','g')

p.psia()
p.atma()
p.atmg()
p.inchWa()
p.inchWg()

gasProperties.py

Functions avaible:

• zfactorBeggsBrill / calculation of the z factor using Beggs and Brill correlation. Explicit approach.
• zfactorDAK / calculation of the z factor using DAK correlation. Implicit approach.
• SGgas / calculate the specific gravity of a gas at given P and T with air reference at 60°F and 1 atm.
• rhoGas / calculate the density in lbs/tf of a gas at given P and T.
• volumeStd / calculate the desired volume in standard conditions: 60°F and 1 atm.
• fluidPressure / calculate the pressure at the bottom of a fluid column.

abacus.py

Function that produces abacus of a function that has 1 or 2 parameters.
