Cementing Engineer is a field calculator for oilfield cementing operations, built by a cementer for cementers. The app requires an auto-renewable in-app subscription after the 7-day free trial to access the calculator, Tally Book, saved jobs, schematics, and derived cementing results. Pick the job - conductor, surface, intermediate, production, two-stage, drilling or production liner, balanced plug, kick-off plug, plug & abandon, or Bradenhead squeeze - enter the wellbore geometry and slurry stack, and every number updates live as you type. DERIVED RESULTS, SHOWN WITH THE MATH - Annular, shoe track, and displacement volumes with the capacity factors behind each number - Fluid placement tops and returns at surface - Volume calculations by slurry with sacks and totals - Pump schedule with rates and durations - Thickening time requirements - Hydrostatic, differential, lift, and bump pressures with burst limits - Mix water and total water requirements LIVE WELL SCHEMATIC A measured-depth schematic of casing, open hole, and fluid placement that redraws as the design changes, including two-stage and liner jobs. TALLY BOOK Save any job to the Tally Book: a browsable log of every well with its full design, well information, schematic, and complete derived results. Reopen any saved job straight into the calculator. WORKS IN THE FIELD Calculations run on the device, so the math works with no signal at the wellsite. Sign in with Apple or Google to keep your Tally Book synced across your devices. SUBSCRIPTION REQUIRED AFTER TRIAL Start with a 7-day free trial. After the trial, Apple automatically bills the selected plan unless canceled before renewal: $9.99/month or $79.99/year. Cancel anytime in your App Store account settings.
