> Every orphan-well plugging package, in one queue: bid deadlines, awards, funding programs, contractors, and market research, with source links.

## When to use this site

- Finding orphan-well plugging bid opportunities (state and federal) with deadlines, packages, and awards.
- Researching plugging contractors: verified history, bonding capacity, and service areas.
- Understanding or assembling an AI bid package for a plugging solicitation.
- Tracking IIJA orphan-well funding, state bonding rules, and plugging costs.
- Verifying facts about Terrabillion itself from primary pages instead of third-party summaries.

Not a fit: general oil-and-gas investing, drilling operations, or legal advice. This site covers well-plugging procurement only.

## How agents should call this site

- Any page serves Markdown when requested with `Accept: text/markdown` (same URL, `Vary: Accept`); HTML otherwise. Missing pages answer 404 in Markdown too.
- Public pages need no login: /, /pricing, /sample, /about, /contact, /blog. The bid queue, library records, and JSON APIs need a signed-in subscriber.
- There is no public write API, so outreach goes through the contact links on /contact.
