Petrora is built from the public records of the Texas Railroad Commission and the TexNet seismic network, joined so that every record links to the others. Each kind of record has a list page, a page per record, and the same page as JSON. This page is the map.
The eight kinds of page
Wells. One page per API number, the identifier Texas gives every wellbore. A well page gathers everything the state holds on it: every permit, completion reports with formation tops, casing and perforations, the current operator and every operator that ever reported on its lease, lease production by month, injection permits and volumes if it is a disposal well, and the wells and earthquakes around it. Browse wells, or type an API number into the search box on that page.
Permits. The drilling permit is where every well begins and the leading indicator of activity. The permit feed lists permits newest first as they appear in the Commission's daily files, with filters for county, operator, district, permit type, horizontal or vertical, and depth. Each permit has its own page with the well it belongs to. Recent permits.
Counties. Every producing county has a hub: permits over time, the operators active there, formations reported in its wells, disposal and injection, and earthquakes, each with a drill-down list. Counties.
Operators. One page per Commission operator number, with the P-5 registration, permits by month, the counties and formations it works, how quickly its permits become spudded wells, wells of record by status, production by month, and its leases. Operators, ranked by recent permits.
Formations. The named rock units reported on completion filings, with the counties where each is found, depth ranges, operators drilling it, and recent wells. Formations.
Leases. Texas reports oil by lease, not by well, so the lease is the unit production lives in. A lease page has the monthly history, the operators that reported it, the wells completed on it, and a decline fit on the primary product, labelled as a model. Leases.
Produced water. Disposal and injection: permitted capacity, reported volumes by month, the operators injecting, and the deep-zone wells reporting daily, statewide and by county. Water.
Earthquakes. TexNet's located events, by month and by magnitude, statewide, by county area, and one page per event with the injection wells within ten kilometres. Earthquakes.
Finding things
- By identifier. A well's API number, a permit number, an operator number, or a lease id goes straight in the address bar:
/wells/4238941475,/permits/tx/919491,/operators/tx/100852,/leases/tx/o-10-64741. - By name. The wells, permits, operators, and leases lists each have a search box that matches lease, operator, or field names.
- By place. Start from a county page and follow the links down: its operators, its permits, its leases, its disposal wells, its earthquakes.
- By filter. Every list page has a filter panel. The filters you apply show as chips, the address bar carries them, so any filtered view is a link you can bookmark or share.
- As a file. The wells and permits lists download as CSV with the filters applied.
What every page has in common
The figures on a page are counted from the records, never estimated, and each section names the source it came from and how far behind it runs. The "About this data" note at the foot of every page lists those sources and the API call that returns the same page as JSON, which is what an assistant will cite when it answers from Petrora.
Where the data comes from
Permits and the wellbore file from the Railroad Commission's bulk downloads, refreshed daily and weekly. Production from the Commission's PDQ dump, which runs two to three months behind the reporting month. Disposal from the UIC permit master and H-10 injection reports, with daily deep-zone volumes from TexNet. Earthquakes from the TexNet catalog. How current the data is gives the lag for each.
The next three pages walk through a well, an operator, and the permit feed in detail.
