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:
- Intuitive graphical interface;
- Ability to work with data files locally and on iCloud;
- Set ranges for graph;
- Graph Options:
- – Surface Pressure and Volume Pumped versus Pumping Time;
- – Surface Pressure and Pumping Time versus Volume Pumped;
- Data edition (add, edit/save, insert, remove);
- Ability to print report with data and graph;
- Click and move mouse in the graph area to obtain Surface Pressure, Equivalent Density, Equivalent Gradient, Volume Pumped and Pumping Time.
- Option to select unit systems: Metric, SI, Field1 (Imperial) and Field2 (mix);
- Selection of units also per parameter;
- Option to select time unit: sec or min;
- Autosave for Description, Unit System, Time Unit (sec/min)
New in this update 1.4 (Mac version only):
– Fix calculation factor for volume unit on the Metric and SI unit Systems.

Oil & Gas Apps for Mac OS X
Oil & Gas Apps for Mac OS X
A few years ago, we searched for applications in the area of oil and gas for Mac OS X and not found. Then, we develop these applications and we would like to share with friends.
We would like to share our portfolio with very low cost applications to drillers, tool pushers, engineers, chemists, students and other professionals in the petroleum industry. These are productivity tools helpful in drilling of oil wells.
These apps are completely interactive and allow users to define a wide variety of parameters for oil wells and unit system, save data, share them with friends.
These Apps are available on the Mac App Store, only.

Well Control Worksheets for iPad 1.5
*** Now available on the App Store ***
This application uses the worksheets based on standardized worksheets of the methods to control oil wells after the occurrence of kick during drilling operations on floating rigs with subsea stack and rigs with surface stack.
This app is great for use in the offices: Toolpusher, drilling engineer, company man, technicians, superintendent and OIM.
It can be used on the rig (offices) by drilling staff and also help in the understanding of the methods of well control.
Well Control Worksheets for Methods:
