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.
