Drilling Cost for iPad, release 2.1, submitted to the iTunes App Store

Drilling Cost for Ipad

 Link to App Store

New in this release:

– iOS5 Tested;
– Improvements with data input: now there is no need to tap [done] for each entry, only on the last text field.
– Autosave for Unit Length, Bit Cost and Rig Cost;
– Add new features: Single Calc view, Graph Options view and Datasheet View;
– Improved the feature save/load data file;

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, analize 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 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)*(LD), LD = total Length Drilled by the dril bit
2) Drilling Cost = c + b (DT) + a (DT)*(DT), DT = total drilling time by the drill bit

Multiple Files:

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

Drilling Hydraulics for Mac submitted to Mac App Store

Drilling Hydraulics for Mac (Snow Leopard)

(iMac, Macbook and Macbook Air)

DH_512x512.png

Awaiting for approval by Apple 

The Drilling Hydraulics provides the driller, tool pushers, engineers, chemists, students and other professionals in the petroleum industry a productivity tool helpful in drilling of oil wells for hydraulics calculations, optimization of the penetration rate and can help on the decision on selection of bit nozzles.

Features: 

1. 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;
2. Options outstanding: Injecting into the drill string with the return flowline or by injecting the kill line to return the choke;
3. Options wells in floating units or in drilling land rigs;
4. Use of two mud pumps in parallel;
5. Choice of rheological models (Bingham and Power);
6. Calculations of the hydraulic drill bit and the system by friction;
7. Frictional losses in all sections, also showing the length, velocity, flow regime, hydrostatic and Reynolds number in each section.
8. Calculation of the ECD on bottom hole and the casing shoe;
9. Hydrostatic calculations at the bottom hole and the casing shoe;
10. Calculation of bottoms up time;
11. Pressure x Flow Rate and scale definition. Ability to change bit depth or bit TFA for instantaneous plotting.
12. Selecting the system of units;
13. Saves the data to reload later.
14. Ability to work with multiple files;
15. Drill string sections: Drill pipe, Heavy-weight drill pipe, drill collar 1 and drill collar 2.
