About this app

Petronaut is a complete toolkit for petroleum engineers and students, bringing daily engineering tools into one clean app that works fully offline. Every formula includes its authoritative source and assumptions, so you get results you understand and trust.

■ 19 ENGINEERING CALCULATORS across four domains:

Drilling:
• Annular Velocity
• Triplex Pump Output
• Wellbore Volume
• Hydrostatic Pressure
• Equivalent Circulating Density (ECD)
• Drill Pipe Capacity
• Maximum Allowable Annular Surface Pressure (MAASP)
• TVD / MD Converter (Minimum Curvature & simple method)

Reservoir:
• Original Oil In Place (OOIP)
• Archie's Water Saturation
• Boyle's Gas Law
• Darcy's Law of Flow

Production:
• Productivity Index
• Gas-Oil Ratio (GOR)
• Water Cut

Mud / Drilling Fluids:
• Barite Addition
• Water Addition
• Plastic Viscosity
• Yield Point

■ WELL CONTROL SIMULATOR:
Train interactively on realistic scenarios: kick, gas migration, and circulation losses. Adjust mud weight, pump rate, choke, and the BOP, monitor SIDPP, SICP, and BHP in real time on a live wellbore schematic, then print a kill sheet.

■ FORMULA REFERENCE:
A searchable library where every formula shows its authoritative source, assumptions, and an explanation of each variable and unit.

■ UNIT CONVERTER:
Quick conversion between pressure, temperature, density, viscosity, volume, and energy units.

■ MORE:
• Works 100% offline
• Modern Material Design 3 interface, light & dark mode
• Full Arabic & English support with RTL
• History log of your past calculations
• Export and share results

Disclaimer: the Well Control Simulator is an educational and training tool, not a field-grade certified instrument for operational decisions.
