The question. Which record answers which question about a well or a unit, and which questions does it leave open?
What a Texas well file holds
The Railroad Commission of Texas (RRC) lists the contents of its oil and gas well records. The table follows that list, adds the coverage dates the agency states, and adds rule text and the RRC geothermal page where marked. It says nothing about any one well, and the list does not say a record exists for any given well.
| Record | What the agency says |
|---|---|
| Application to drill (Form W-1) and plat | Part of the well records. Applications submitted after May 2005 are electronic only. Commission rule 3.5 covers applications to drill, deepen, plug back or reenter any oil well, gas well, brine production well or geothermal resource well. |
| Completion report (G-1 or W-2) | Part of the well records, with attachments. |
| Well logs | Images received since July 2004 are online in the Imaged Records Query and Public GIS Viewer. Logs from September 1985 forward also exist on paper and microfiche, with the paper logs stored off-site. |
| Plugging report (W-3) | Part of the well records, with attachments. Commission rule 3.14 requires an operator to give the Commission notice of its intention to plug any well drilled for oil, gas or geothermal resources or for any other purpose over which the Commission has jurisdiction, except those the rule excludes, such as seismic holes and core holes. |
| Production data | 1993 to the present is online. 1992 and earlier is on microformat. |
| Geothermal production wells | The RRC geothermal page lists Forms W-1, W-2/G-1, GT-1 and GT-2 for geothermal energy production wells. Commission rule 3.58(b) requires producers of geothermal resources to file monthly reports on Form GT-2. |
The well records page is written about oil and gas, and its production section does not mention Form GT-2. This guide does not say where geothermal filings are published.

Operator and well status
Source: 16 Texas Administrative Code Chapter 3, sections 3.15 and 3.58, Transferring Wells to New Operators and Geothermal, Railroad Commission of Texas; Texas Natural Resources Code, Chapter 89, section 89.047, Texas Legislature. Read October 4, 2026.
Operator of record. The Commission's rule says the Form P-4 establishes the operator of an oil lease, gas well or other well and certifies responsibility for regulatory compliance, including plugging, and that the Commission may require evidence that the transferee has the right to operate when a P-4 changes the operator. An applicant who cannot get the previous operator's signature can file a P-4 with an explanatory letter and legal documentation of the applicant's right to operate the property. Before approval, the rule says the Commission notifies the last known operator of record, if that operator's address is available, and gives the operator an opportunity to protest. The rule text above does not describe a P-4 as a title or lease instrument. On the part of its Geothermal page about injection wells for geothermal energy, the Commission says a geothermal energy operator must have an active Form P-5 (Organization Report) and must be the Form P-4 (leaseholder) of an on-schedule well. The page does not say what on-schedule means. This guide does not say how the page's word leaseholder relates to the rule's wording.
Inactive wells. The rule defines an inactive well as an unplugged well that has been spudded (drilling has started) or equipped with cemented casing and has had no reported production, disposal, injection or other permitted activity for more than 12 months. The rule's definitions are written for oil and gas operations, and this guide does not say how it applies to a geothermal well. The Commission says that once it approves a P-4 transferring operatorship, the prior operator is no longer responsible for the inactive well provisions and the acquiring operator has six months from the date of approval to bring inactive wells into compliance with the rule.
Orphaned wells. This is a different status. For the orphaned well program, Natural Resources Code section 89.047 defines an orphaned well as a well with a Commission permit that has no reported production or other Commission-jurisdiction activity for the preceding 12 months and whose operator's organization report has lapsed. The same section says the Commission shall designate a person as operator of such a well if the person files, among other things, a factually supported claim, based on a recognized legal theory, to a continuing possessory right in one of three things accessed by the well: the mineral estate; the "geothermal energy and associated resources estate"; or the geologic space, for the purpose of a geothermal energy conservation well. For the geothermal estate, the text says the claim is established by a current geothermal lease, a recorded deed conveying a fee interest in the geothermal estate, or any other documentation of an interest in it. A land desk reads those documents. It does not decide the claim.
Louisiana wells and units
The Office of Conservation says all engineering documents and issued permit documents it received since 2000 are imaged by serial number, and that older well files may have documents that are not imaged, available on microfiche, reel or paper. The state's SONRIS (Strategic Online Natural Resources Information System) guides list tutorials on well searches by serial number, organization name, permit date and section-township-range. A 2025 act requires reporting of oil, gas and condensate production on an individual well basis; the digest does not say what SONRIS publishes or from what date.
Two Louisiana unit records are described here. Field orders reflect unitization (the pooling of tracts) matters, among other things, and the agency says all of them are imaged by order number in SONRIS Document Access. The agency describes unit survey plats as plats depicting the mineral ownership of a pooled unit, required only for units that produced, with most of the plats it received imaged and indexed by field order. The same guide also lists dockets, the hearing transcripts and exhibits associated with unitization matters, and says most dockets have not been imaged but are available for public review at the LaSalle Building, 9th floor.
This guide gives no agency coverage statement for Texas unit designations, because none was read for it. In the made-up area below, the unit outline is read from the unit designation on file.

A made-up area, well by well
Plate 1 is the made-up area from guide 1. This time the question is what each record says about each well. If the area were in Texas, the table would read like this.
Where each line is read
- Survey section linecounty records and plats
- Tract linedeeds in the county records
- Lease boundarythe lease itself, and any release
- Unit outlinethe unit designation on file
- Wellagency well records
- Pipeline easementthe easement instrument
The lines do not match. W2 sits inside the unit but outside the lease. W3 sits inside both. Each fact is read from its own record.
| Well | Lease and unit position | Records that speak to it |
|---|---|---|
| W1 | On the edge of unit U1 as drawn, outside lease L1 | The unit designation's own description of the unit, read against the well location in the agency well file. The drawing cannot settle it. |
| W2 | Inside unit U1, outside lease L1 | The unit designation on file; the agency well file. |
| W3 | Inside both U1 and L1 | The lease and any release; the unit designation; the agency well file; the Form P-4 for the operator of record. |
| W4 | Inside L1, outside U1 | The lease and any release; the agency well file; production data. |
What stays open
Some questions no well or unit record answers on its own. Who holds the minerals at a given depth is read from deeds and reservations. Whether a lease is still in force is read from the lease and its releases, together with facts such as production that the lease makes relevant. The Railroad Commission says it has no authority over lease and royalty matters or property rights matters. A well file does not settle either question.
A land package shows these open items as a list, next to the wells they belong to, rather than filling them in by inference. Guide 4 shows what that list looks like.
