For Texas oil & gas operators

W-3 compliance, automated.

Caprock listens during the plug, drafts your W-3 + W-15, validates every cement volume against TAC §3.14, and submits to the RRC. Built on a deterministic rule engine that won't hallucinate volumes — and an LLM that knows when to ask.

$1 fully refundable. Locks your launch-tier price ($299/mo) for 12 months.

What it does

Three engines. Zero hallucinated facts.

Every fact-bearing path is deterministic, auditable Python. The LLM only routes, classifies, and narrates around the trusted core — so an inspector or operator can audit the math line by line.

Cement volume math

Cylinder + annulus volumes in ft³, bbl, sacks. TAC §3.14 general rule and the BUQW-not-covered special case encoded as deterministic functions, validated against five sample wellbore geometries.

API-keyed pre-fill

One API number pulls operator (RRC P-5), well master (RoRQ), GAU letter, and completion record. Every W-3 field carries source-of-truth metadata. Operator/RRC mismatches surface as warnings, not silent errors.

Voice-to-narrative

Operator dictation goes in; W-3 Section IX surface-restoration prose comes out. Regex-extracted facts with provenance, missing slots flagged with placeholders. Validated on 8 golden field-voice transcripts.

Architecture

Why operators trust the math.

Hallucination on cement volumes or plug placement is unacceptable — a missed plug at the base of usable-quality water is a violation. So the LLM never does arithmetic. It calls tools.
