The most complete, flexible and versatile petroleum calculator for professionals in the oil and gas industry!
Now also available for desktop!
IMPORTANT NOTE: for users who have problems with the keyboard (dot or comma not showing): some of the newer Android devices seem to have a bug in the soft keyboard, that results in the absence of dot / comma on the number keypad. The solution is to install an alternative keyboard (such as the Google keyboard).
Oil Calculator Pro is the Pro version of Calculator for Oil enhanced, the indispensable companion for cargo and bunker surveyors, expeditors, chief officers on oil and gas tankers, and other professionals in the oil and gas industry.
The app uses the ASTM tables / formulas to calculate weights and volumes based on entered density or API, obs volume, pressure and temperature, and calculates the following:
- VCF
- MTons (vac)
- MTons (air)
- GSV (M3 @15)
- BBLS (@60)
- LTons
- Gallons
Contains a blending tool for viscosity, flash point, pour point, and temp/viscosity calculation.
Contains an export utility so the user can copy calculator screen data into a database for future reference.
The app has both ASTM 1980 and 2004 tables (including updates 2007 and 2009), and users can select which table to use for the calculator in the settings screen. Users can also select whether they want to calculate using SI Metric or Imperial units.
Oil Calculator Pro gives you direct access to the following ASTM tables for calculations concerning Crude Oil, Products, Lubrication Oils and Special Applications:
- table 5 A/B/D, 6 A/B/C/D, 23 A/B/D, 24 A/B/C/D, 53 A/B/D, 54 A/B/C/D, 59 A/B/D, 60 A/B/C/D
In addition to that, the following NGL/LPG tables are directly accessible (version 2004):
- table 23E / 53E / 59E
Furthermore, the calculator makes use of the following tables for conversions and calculation of CTL/CPL:
- table 24E / 54E / 60E
Precision can be changed using the settings screen. Settings are saved in the app so that when you use the app next time it will calculate with your chosen settings. The precision setting for VCF is also set automatically when the user selects 1980 or 2004 tables, but this can be overridden.
Densities can be entered in the following formats which are automatically recognized:
e.g 0.9664 / 966.4 / 9664
The app can calculate for crude oil, black and white products, lubrication oils and special applications, and input can be changed between density in vacuum at 15 and 20 deg C/ API / relative density / observed density, and degrees Celsius / Fahrenheit by touching the applicable buttons. Also when using 2004 tables, the input of pressure is enabled and can be switched between psi, kPa and Bar.
The user has the choice to calculate using observed M3 / M3 at 15 / observed Barrels / Barrels 60 / Metric tons air/Metric tons vac / Ltons / Gallons. All other parameters are then calculated accordingly using the entered temperature, density (and pressure if 2004 version table is used).
The user can also calculate weights of LPG / NGL, using either density @ 15C, relative density @60F, observed density or density @ 20C.
Aside from the conversion screen with conversions between API, observed density, density 15, density 20 and relative density for petroleum products/Crude Oil and Lubrication Oil, there is also a screen with conversions used in LPG / NGL, as well as an LPG density calculator.
For products, lube oils and crude there are two tools for calculating final density when blending two components: one tool that calculates the blend after loading the 2nd component, and another tool that lets the user choose the two components and advises which component to load first, based on density 15C or API 60F and actual temperature of the components. The blending tools also apply volumetric shrinkage as per API MPMS Chapter 12.3
