Mud Engineer Lite

Rig Floor Tech

About this app

Mud Engineer Lite is a fast, offline calculation toolkit built for drilling-fluid (mud) engineers — the everyday rig-floor numbers, in one clean app. This free version gives you 3 essential calculators; upgrade to Mud Engineer Pro to unlock all 20.

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.

3 FREE 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
- Hole Cleaning — annular velocity, cuttings slip velocity & transport ratio

UNLOCK ALL 20 CALCULATORS WITH PRO
Upgrade to Mud Engineer Pro to add:
- Drilling Hydraulics — TFA, jet velocity, bit pressure drop, HHP, impact force, annular pressure loss & ECD
- 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
