Introducing the Mud Engineer App: Your Ultimate Drilling Calculation Companion!
Mud Engineer App – Drilling Fluids Calculator
Mud engineers play a crucial role in keeping drilling programs running smoothly. The Mud Engineer App is an essential field tool that gives you 14 drilling-fluid and well-control calculators in one place, built for rig work: fast input, clear step-by-step equations, professional PDF reports, and full offline use.
CALCULATORS
• Final Mud Weight – mix two fluids and get the resulting weight and volume
• Volume – volumes of two fluids needed to build a required volume at a target weight
• Reduce Mud Weight – barrels of a lighter fluid (water, seawater, diesel) to dilute the mud
• Weight Up – sacks, lb/bbl, total material, volume increase and final volume (barite, CaCO3, hematite)
• Hydrostatic Pressure and pressure gradient
• Equivalent Circulating Density (ECD)
• Annular Velocity
• Triplex Pump Output – bbl/stroke, bbl/min and flow rate
• Kill Sheet – Kill Mud Weight, ICP and FCP, with safety margin
• Bottoms Up – annular volume, strokes and time
• Pipe Capacity & Displacement – open-ended and closed-end
• Oil/Water Ratio – from retort readings, with oil or water to add to reach a target ratio
• Rheology – PV, YP, apparent viscosity, n and K from Fann 600/300 readings
• EMW & Pressure Gradient
BUILT FOR THE FIELD
• Step-by-step worked equation with your own numbers, plus the formula reference
• Change units right inside each field – values convert automatically
• Quick-value chips: barite, CaCO3, hematite, water, seawater, diesel, sack sizes, pump efficiency
• Smart checks catch unit slips (e.g. 35 typed into an SG field) and impossible inputs
• Values carry over between calculators: pump output feeds Bottoms Up and Annular Velocity, the new mud weight feeds Hydrostatic, ECD and Kill Sheet
WELLS & HISTORY
• Manage multiple wells (name, rig, field); each well keeps its own calculations and values
• Every calculation is saved automatically in a searchable history, filtered by well, date or calculator
• Export history to CSV (Excel) or a combined PDF
PROFESSIONAL PDF REPORTS
Input and result tables, the worked equation, the reference, the well, your name or company, the date and an app watermark – ready to share.
UNITS & SETTINGS
• Oilfield and metric units: ppg, SG, g/cm³, kg/m³, pcf, bbl, m³, gal, L, ft, m, in, mm, psi, bar, kPa, gpm, L/min, bbl/min, m³/min
• Exact unit conversions
• English and Arabic interface
• Favorites and search on the home screen
• Adjustable decimal places, light or dark theme
• Works fully offline – no account, no ads, your data stays on your device
Formulas follow standard oilfield references (Lapeyrouse, Formulas and Calculations for Drilling; IWCF kill sheet; API RP 13B) and are verified against published worked examples.
Special thanks to Eng. Mahmoud Elbeltagy for contributing to the development of these calculations.
