Features:

This application uses the basic calculations of the methods to control oil wells after the occurrence of kick during drilling operations on floating platforms and land rigs.

This full version is completely interactive and allows users to define a wide variety of parameters for oil wells and unit system, save data and more.

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

Well Control Methods:

1. Driller’s Method
2. Wait and Weight
3. Dynamic Volumetric
4. Static Volumetric – Migration / Bleed
5. Static Volumetric – Lubrication / Bleed – Top Kill

Notes:

– For well control simulation, use another app “Well Control Simulator“.

– For simulation of leak-off test, use another app “Leak-Off Test Simulator“;

– For kick tolerance analysis , use another app “Kick Tolerance“;

– For drilling simulation, use another app “Drilling Simulator“;

– For hydraulic calculations, use another app “Drilling Hydraulics“;

– For kill sheets, use another app “Well Control Worksheets” (iPad and Mac only).

These tools can complement (work with) this simulator by importing /exporting data files which can be used in this application;

Kick Tolerance for Mac 3.0 available on the Mac App Store

Kick Tolerance for Mac (OS X)

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 Gradient;

2. For KT as Maximum Pit Gain Volume:

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

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 data files locally and on iCloud;
4) Sharing Data Files with iCloud and importing wells from other apps;
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: Metric, SI, Imperial and Mix;
11) Selection of units also per parameter;
12) Drill string sections: drill pipe 1, drill pipe 2, heavy weight, drill collar 1 and drill collar 2.
13) Directional basics Hydrostatic calculations (KOP, Bottom Hole and Casing Shoe TVD and Measured Depth)
14) Ability to send data file by email;

Drilling Cost for iPad 3.0 redesigned for iOS 7

Drilling Cost for iPad 3.0

Redesigned for iOS 7

Now available on the App Store !

Features:

The Drilling Cost provides to the drillers, toolpushers, drilling engineers, students and other professionals in the petroleum industry a productivity tool helpful in drilling operation to calculate the drilling cost per length unit drilled, analysis of drill bit performance and to use in planning phase of oil wells.

Formula:

Drilling Cost = (Bit Cost + Rig Cost x (Drilling Time + Trip Time)) ÷ (Length Drilled)

Drilling Cost => drilling cost $ per length unit ($/ft, $/m)

Bit Cost => bit cost, $

Rig Cost => rig cost per hour, $ / hour

Drilling Time => total drilling time, hour

Trip Time => trip time, hour

Length Drilled => total length drilled by drill bit, ft or m

The Advanced Feature:

This application provides an advanced feature that is the modeling of data Drilling Cost vs. Drilling Time and also vs. Length Drilled using quadratic regression. The minimum point of the parable may correspond to the operation time of the drill bit, where will occur the minimum cost. The more the R squared is close to 1, the result will be better.

Quadratic regressions:

1) Drilling Cost = c + b (LD) + a (LD)^2, LD = total Length Drilled by the dril bit

2) Drilling Cost = c + b (DT) + a (DT)^2, DT = total Drilling Time by the drill bit

Data Files:

The user can work with data files that must correspond to the drill bits used in each phase of drilling.
