Everything a mud engineer needs in the field — rheology, hydraulics, well capacity, kill sheets and unit conversion. 50+ calculators, fully offline, in your pocket.
Every module speaks the language of the daily report — Fann readings, Pf/Mf, ECD, pit volumes — so logging in the field takes seconds, not spreadsheets.
PV, YP, gel strength, Power Law index & consistency from your Fann readings — with a live rheogram.
Annular velocity, hydrostatic pressure and ECD, calculated the way you run them on the rig.
Full wellbore profile — casing, liner, open hole, drill string — with accurate volume & stroke figures.
Fluid mixture formulas, barite loading and mud weight adjustments without the back-of-envelope math.
Salinity weight %, NaCl load and final density for brine and salt-saturated systems.
Diagnose carbonate, bicarbonate and other contamination from your titrations — flagged automatically.
LGS, CaCO₃, HGS, ASGS and more — full solids breakdown from routine measurements.
Balanced plug, heavy pill / slug spotting and other advanced jobs, driven by your real well profile.
Frictionless conversion across ppg, SG, psi, bar, bbl, m³ and every unit the field actually uses.
Built-in wait & weight method with pre-recorded well data, formation strength & MAASP, kill fluid density and a full circulating plan — then exported as a standard kill sheet in one tap.
MudFlow is free during closed testing. Feedback from real wells shapes what ships next.
Join the MudFlow closed testing group with the Google account you use on your Android device.
Once opted in, install MudFlow (Early Access) from the Play Store like any other app.
Use it on an actual well if you can — then leave feedback from the app listing so it reaches the developer.
Know your mud — before it costs you the well.
