Well Control Worksheets for iPad

WCWS_170_ic.png

Awaiting for Approval by Apple

Others apps for iPhone and iPad by Carlos Moura on 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.

It can be applied on the field and also help in the understanding of the methods of well control.

Well Control Worksheets for Methods:

– Driller’s Method
– Wait and Weight Method

– Option to select “Subsea Stack” or “Surface Stack”
– Option to Select Unit Systems: METRIC, SI, FIELD1 (Imperial) and FIELD2.

Leak-Off Test Simulator for iPad 1.0 now available on the iTunes App Store

Leak-Off Test Simulator for iPad

LOTSim_512_1.png

App Store

This app provides a graphical very useful tool for training of Technicians, Drillers, Toolpushers, Drilling Engineers, Students and others professionals of the oil & gas industry to simulate leak-off test and more: hydraulics, hydrostatic, capacities and volumes, ability to select unit systems: Metric, Si, Imperial and Field (mix), very useful for filling well control worksheets.

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.

Kick Tolerance for Mac OS X Lion 1.0 now available on the Mac App Store

Kick Tolerance for Mac OS X Lion

KT3.png

On the Mac App Store

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 version is completely interactive and allows users to define a wide variety of parameters for oil wells, save data to files.

This application deals with two concepts:

1- Kick Tolerance as Maximum Pore Equivalent Weight;
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.

1. For KT as Maximum Pore Equiv Weight

– Plot KT x Maximum Kick Volume

KT (Maximum Pore Equiv Weight) = mudWeight + (casingShoe/wellDepth) * (Fract Equiv Weight – mudWeight) – (KickLength/wellDepth) * (mudWeight – kickDensity);

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

2. For KT as Maximum Pit Gain Volume:

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

KI (Pore Equiv Weight – Mud Weight)
= (casingShoe/wellDepth) * (Fract Equiv Weight – mudWeight) – (KickLength/wellDepth) * (mudWeight – kickDensity);

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

Calculation of the Kick Tolerance by this App:

1. Hmax below the casing shoe = (MaxSICP – SIDPP) / (0.052 x (ρmud-ρkick));
– MaxSICP = 0.052 x (ρfracture – ρmud) x CasingShoeTVD
– SIDPP = 0.052 x KI x Well TVD
2. Calculate V1 = Maximum Volume annulus bellow the casing shoe;
3. Calculate V2 at bottom = (V1 x Pfracture) / Ppore;
4. Calculate V3 = Volume annulus at bottom using Hmax;

The kick tolerance is the smaller of the two volumes between V2 and V3.
This KT is showed in the Graph: KI versus KT 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)
