Kick Tolerance for Mac OS X Lion submitted to the Mac App Store

Kick Tolerance for Mac OS X Lion

(iMac, Macbook and Macbook Air)

KT3.png

Awaiting for approval by Apple

The Kick Tolerance provides to drilling engineers, chemists, technicians, students and others professionals in the Oil & Gas industry a productivity tool helpful in drilling operation (well control) and planning phase of oil wells.

This application deals with two concepts:

1- Kick Tolerance as Maximum Pore Gradient;
2- Kick Tolerance as Maximum Kick Volume.

Both with graphical analyzes.

For both the concepts, the calculations uses the Fracture Gradient defined in “Well Configuration -> Gradients” views.

For KT as Maximum Pore Gradient:

– Plot KT x Maximum Kick Volume

KT (Maximum Pore Gradient) = mudWeight + (casingShoe/wellDepth) * (fractGradWEq – mudWeight) – (KickLength/wellDepth) * (mudWeight – kickDensityWeq);

=> Known the Maximum Kick Volume, find the KT as the Maximum Pore Gradient;

For KT as Maximum Pit Gain Volume:

Plot KI = the difference ( Pore Gradient – Mud Weight ) versus Maximum Kick Volume (Pit Gain)

KI (Pore Gradient – Mud Weight)
= (casingShoe/wellDepth) * (fractGradWEq – mudWeight) – (KickLength/wellDepth) * (mudWeight – kickDensityWeq);

=> Known the difference (Pore Gradient – Mud Weight), find the Kick Tolerance as Maximum Kick Volume.

Others features:

1) Calculations of the Choke Line Effect;
2) Included the formulas;
3) Ability to work with multiple files (save / load data file);
4) Pop-up view to alert user about invalid values;
5) Views with calculations of capacities, volumes and more.
6) Defining the parameters of the well, drill string, drill bit, mud (fluid), mud pumps, circulation lines on surface, diameter and coefficient of choke and more;
7) Options wells in floating units or in drilling land rigs;
8) Choice of rheological models (Bingham and Power);
9) Hydrostatic calculations at the bottom hole and the casing shoe;
10) Selecting the system of units;
11) Drill string sections: Drill pipe, Heavy-weight drill pipe, drill collar 1 and drill collar 2.
12) Directional basics Hydrostatic calculations (KOP, Bottom Hole and Casing Shoe TVD and Measured Depth)

Leak-Off Test Analyzer for iPhone now available on the iTunes App Store

Leak-Off Test Analyzer for iPhone

LOT_170x170B.png

App Store

This app provides for Technicians, Drillers, Toolpushers, Drilling Engineers, Students and others professionals of the oil industry a very helpfull tool to analysis and use during the performing of the leak-off test in wellsite.

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. Intuitive graphical interface;

2. Ability to work with multiple files;

3. Set ranges for graph;

4. Graph Options:

– Choke Pressure and Volume Pumped versus Pumping Time;

–  Choke Pressure and Pumping Time versus Volume Pumped;

5. Data edition (add, edit/save, insert, remove);

6. Ability to send screenshots by email;

7. Ability to print via AirPrint

8. Tap with finger and moving it in the graph area to obtain Choke Pressure,

Equivalent Density, Equivalent Gradient, Volume Pumped and Pumping Time.
