Some apps what I am developing for iOS (iPhone, iPad) and MAC OS X are parts of code of a drilling simulator what I have developed for 23 years for MSDOS and currently for Windows 7 to the Wellcon – Well Control School in Brazil (http://www.wellcon.com.br).
This simulator has a coiled tubing simulator for training in well control at workover operations (basic operations, hydraulics, pumping multi fluids, production).

Leak-Off Test Simulator for iPad

About the Leak-off Test on drilling operations:
A test to determine the strength or fracture pressure of the open formation, usually conducted immediately after drilling below a new casing shoe.
Initially, pumping fluid into the borehole results in volumetric compression of the drilling mud column and elastic expansion of the casing string plus rock around the borehole. As the pressure in the borehole increases, the leak-off pressure (LOP) is reached when the relationship between pressure increase and volume of fluid pumped deviates from linear. This occurs when fluid begins to diffuse into the formation at a more rapid rate as the rock begins to dilate. Generally, a LOT is a test that finishes immediately after LOP is reached.
Features:
1. Panel with the following parameters: pump pressure, choke pressure, mud pump speed, strokes totalizer, flow rate, mud weight and volume;
