Drilling Cost – A new App for iPhone and iPad


A new App designed for both iPhone and iPad

Now available on the App Store


The Drilling Cost Advanced provides to the drillers, toolpushers, drilling engineers, students and other professionals in the petroleum industry a productivity tool helpful in drilling operations to calculate the drilling cost per length unit drilled, analysis of drill bit performance and to use in the planning phase of oil wells.
Drilling Cost = (BC$ + RC$ (DT + TT)) ÷ LD

BC$ = Bit Cost,$
RC$ = Rig Cost per hour, $ / h
DT = Drilling Time, h
TT = Tripping Time, h
LD = Length Drilled (foot or meter)

Quadratic Regression:

This application provides an advanced feature that is the modeling of data Drilling Cost vs. Length Drilled (or Drilling Time) using quadratic regression. The minimum point of the parable may correspond to the 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.

Drilling Cost = c + b (LD) + a (LD)ˆ2

The result is shown on graph analysis (see screenshots)
