Formula & Job Design
From a job description to quantities, recipe, and a first-pass price.
A cementer looks at a well's casing, depths, and temperature and decides the slurry, how many sacks, how much water and displacement, and what to charge.
WHO BUYS IT · Pumping and cementing services · Specialty contractors with recipe-driven work · Any trade that quotes from capacity tables
INPUTS
- Casing size and weight
- Plug interval (top and bottom depth)
- Cement class and additives
- Excess percentage
- Regulating state
THE PROPOSAL
- Balanced-plug volumes (slurry, spacer, displacement)
- Sacks, mix water, and additive quantities
- A job ticket with placeholder rates
- Rule checks against the state's minimum plug
WHAT THE EXPERT CORRECTS (CAPTURED AS RULES)
- Slurry choice by depth or temperature
- Excess by hole condition
- Standby and mileage on the ticket
WHERE THE LANGUAGE MODEL EARNS ITS PLACE
Reads a free-text well summary into structured inputs and drafts the job narrative. The volumes are arithmetic from the capacity tables and never come from the model.
