## What is Mud Engineer Pro?

Mud Engineer Pro is a fast, offline calculation toolkit built for drilling-fluid (mud) engineers — the numbers you run every tour, from routine mud checks to well-control-critical calculations, all in one clean app.

Built by a former mud engineer, every formula is checked the way you'd check it yourself: against real daily reports and published API references.

20 RIG-FLOOR CALCULATORS
- Mud Weight & ECD — hydrostatic, ECD, pore/frac margins, HPHT downhole density
- Rheology — PV, YP, n, K, gels and the Herschel-Bulkley model
- Drilling Hydraulics — TFA, jet velocity, bit pressure drop, HHP, impact force, annular pressure loss & ECD
- Hole Cleaning — annular velocity, cuttings slip velocity & transport ratio
- Solids Analysis (retort) — LGS/barite split, OWR, shaker efficiency
- Filtration / Fluid Loss — API & HPHT filtrate, cake, spurt
- Mud Alkalinity — Pf/Mf, OH/CO3/HCO3, excess lime
- Barite Sag Risk, Pilot Test, Mud Formulation & Brine mixing
- Kill Sheet, Cement Job, Wellbore Schematic, Swab & Surge, Trip Tank, LCM Pill, Well Volumes & Strokes, Unit Converter

WHY MUD ENGINEERS USE IT
- Accurate, field-proven formulas — verified against published API references
- Works fully offline — no signal needed on the rig, no data leaves your phone
- US oilfield AND Metric units — switch with one tap
- A clean, professional interface with automatic Dark & Light mode
- One-time purchase — no subscription, no ads

Mud Engineer Pro is a quick-reference aid. Always verify results against your company's approved procedures before acting on any operational, safety-critical or well-control decision.
