About Drilling Calculator for Rigs
DERRICK is a fast, accurate drilling and well-control calculator for the rig floor. Set up your well once and every calculator pre-fills from it, so you only change what is different today. Built for drilling engineers, toolpushers, company men, mud engineers, and students who need the right number under pressure.
- Your active well pre-fills every calculation. Less typing, fewer mistakes.
- Tap show your work on any result to see the formula with your exact numbers.
- Works fully on device. No account, no sign-in, no tracking.
- Field or SI units on every input and result.
- iPhone and iPad, with a purpose-built two-pane layout on iPad.
CALCULATORS
- Pressure and gradient: hydrostatic pressure, equivalent mud weight, equivalent circulating density, bottomhole pressure.
- Well control: kill mud weight, formation pressure, MAASP, LOT and FIT to EMW, kick tolerance, gas expansion.
- Hydraulics: pump output, annular velocity, strokes and lag, bit hydraulics.
- Volumes and capacities: pipe and hole capacity, annular capacity, pipe displacement, slug volumes.
- Mud and tubulars: weight up with barite, buoyancy factor, trip margin, and more.
MUD WEIGHT WINDOW
- See pore pressure, mud weight, ECD and fracture across the whole hole.
- Tap or drag the chart to read every value and your margins at any depth.
KILL SHEET
- Enter shut-in pressures and get kill mud weight, ICP, FCP and a step schedule.
- Automatic gas influx indication from the casing to drillpipe differential.
AI CO-PILOT
- Ask questions grounded in your active well and get clear, field-ready answers.
- Explain any calculation, interpret a kick, or draft an end of tour handover.
- Decision support only. It always defers to written procedure and the on-site supervisor.
HISTORY AND EXPORT
- Save any result to your well log with a note, then filter and search the log.
- See your activity heatmap and export clean reports.
Unlimited wells, the full history, export and reports, unlimited AI, and specialist modules like casing design.
PRIVACY
- Your wells and calculations stay on your device. No analytics, no ads, no tracking.
SAFETY
- DERRICK assists calculation. It does not replace your company well-control procedures, the well program, or the judgment of the on-site supervisor. Always verify independently before acting.
