## What is Cement Calculator?

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.
