Mud Engineer vs Cement Calculator

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.

Cementing Calc is an offline calculator for oilfield cementing jobs. Build the job in the order you pump it and get slurry volumes, sack counts, mixing water, displacement, expected returns, top of cement, and the pressures that matter — with the math shown so you can check every number against your own tables. Built for the field: • Works fully offline — no account, no login, no signal • Every job type — surface and production casing, liners, balanced plugs, squeezes, and multi-stage (DV tool) jobs • Any geometry — multiple previous casings, hole sections, and tapered strings, any sizes • Pump-sequence builder — spacers, cement, plugs, tool opens, and displacement in pump order • The pressures — max wellhead / frac limit, ISIP, ECD, and pulling stands for balanced plugs • Shows the work behind every result • Save jobs and export a PDF or picture to your Files Important: Cementing Calc is a comparison and estimation aid, not a source of final job figures. A competent, qualified person must independently verify every value against official tables, equipment ratings, and the approved job program before any mixing or pumping.
