Beautifully designed and laid out the Geologist's Little Helper USA is a pleasure to use with built in checks and limits, email results functionality, and a shake to reset function. This app is built for the USA using imperial units for input and output.
At the press of a button you can capture the results of any page and email them from within the application. Once you are done with a page you can shake the phone and the page will reset.
Functionality includes-
Oil Zone Analysis
Gas Zone Analysis
Leak Off Test
Formation Temperature
Corrected D Exponent
The Application is fully self contained requiring only minimal input to perform complex calculations.
All Little Helper Apps have built in checks and limits to validate user input, prevent typo's and prevent erroneous answers from being returned. The checks and error message setup is such that you will not be prevented from working with values outside the built in limits, rather a warning pops up to let you know the values in question are either very high or very low for a given situation. However where the answer makes no sense at all you will be prompted to check the input. You can leave the applications, make a phone call, find a restaurant, play a game, whatever it happens to be then come back to the Little Helper and any data that you had entered will still be there.
The Oil and Gas Zone Analysis is an excellent quick look assessment of potential hydrocarbon bearing zones. It includes Shale corrections, Water Zone/Rw calculations, Archies Swa and Rwa, and Reserves and Productivity calculations.
Detailed flip side (info) views provide extra information and make some suggestions as to appropriate input.
