Full description

MudMan is the oilfield calculator and digital tally book built for mud engineers, derrickmen, and fluid service technicians running the rig. Get instant downhole, pump, volume, and pressure calculations without pulling out a paper tally book, annular capacity, hydrostatic pressure, barite increase, ECD, and more, all pulled from your active well. Built by a mud man, for mud men, not a generic oilfield toolkit. WHAT IT DOES Enter your rig and well specs once. MudMan carries them through every calculation: pump output, strokes, volumes, pressures, weight ups, so you're not re-keying the same numbers on every card. Six core calculators are free, no account needed: Surface to Surface Strokes to Bit Bottoms Up Annular Capacity Pipe Capacity Barite / CaCO3 / Hematite Weight Up MUDMAN PRO unlocks the rest: well profiles (Operator → Pad → Rig → Well), drilling update logs, BHA and bit tracking, tank farm volumes, the full calculator library with auto-prefill from your active well, calculation history, and the digital tally book with PDF export sized for standard sleeves. OFFLINE FIRST, ALWAYS Every well profile, calculation, and tally card lives on your device. No signal required on location, MudMan works the same in the doghouse or three miles from the nearest tower. TALLY BOOK, DIGITIZED Reference cards for VIS cup flow rate, hydrostatic pressure, barite increase, alligation math, and more live on your phone, or exported to PDF and printed to fit your existing tally book sleeves. PRICING Free — 6 core calculators, manual entry. Try it for a hitch — 14 day full access trial. Monthly — $12.99, cancel anytime. Annual — $99.99 (~$8.33/mo). Built in the field, tested in the field. MudMan is in active development, and beta feedback shapes what ships next.
