TITLE 16ECONOMIC REGULATION
PART 1RAILROAD COMMISSION OF TEXAS
CHAPTER 3OIL AND GAS DIVISION
RULE §3.16Log and Completion or Plugging Report

(a) Definitions. The following words and terms, when used in this section, shall have the following meanings, unless the context clearly indicates otherwise:

  (1) Basic electric log--A density, sonic, or resistivity (except dip meter) log run over the entire wellbore.

  (2) Drilling operation--A continuous effort to drill or deepen a wellbore for which the commission has issued a permit.

  (3) Operator--A person who assumes responsibility for the regulatory compliance of a well as shown by a form the person files with the commission and the commission approves.

  (4) Well--A well drilled for any purpose related to exploration for or production or storage of oil or gas or geothermal resources, including a well drilled for injection of fluids to enhance hydrocarbon recovery, disposal of produced fluids, disposal of waste from exploration or production activity, or brine mining.

(b) Completion and plugging reports. The operator of a well shall file with the commission the appropriate completion report within 30 days after completion of the well or within 90 days after the date on which the drilling operation is completed, whichever is earlier. The operator of a well shall file with the Commission an amended completion report within 30 days of any physical changes made to the well, such as any change in perforations, or openhole or casing records. If the well is a dry hole, the operator shall file with the commission an appropriate plugging report within 30 days after the well is plugged.

(c) Basic electric logs. Except as otherwise provided in this section, not later than the 90th day after the date a drilling operation is completed, the operator shall file with the commission a legible and unaltered copy of a basic electric log, except that where a well is deepened, a legible and unaltered copy of a basic electric log shall be filed if such log is run over a deeper interval than the interval covered by a basic electric log for the well already on file with the commission. In the event a basic electric log, as defined in this section, has not been run, subject to the commission's approval, the operator shall file a lithology log or gamma ray log of the entire wellbore. In the event no log has been run over the entire wellbore, subject to the commission's approval, the operator shall file the log which is the most nearly complete of the logs run.

(d) Delayed filing based on confidentiality. Each log filed with the commission shall be considered public information and shall be available to the public during normal business hours. If the operator of a well desires a log to be confidential, on or before the 90th day after the date a drilling operation is completed, the operator must submit a written request for a delayed filing of the log. When filing such a request, the operator must retain the log and may delay filing such log for one year beginning from the date the drilling operation was completed. The operator of such well may request an additional filing delay of two years, provided the written request is filed prior to the expiration date of the initial confidentiality period. If a well is drilled on land submerged in state water, the operator may request an additional filing delay of two years so that a possible total delay of five years may be obtained. A request for the additional two year filing delay period must be in writing and be filed with the commission prior to the expiration of the first two year filing delay. Logs must be filed with the commission within 30 days after the expiration of the final confidentiality period, except that an operator who fails to timely file with the commission a written request under this subsection for an extension of the period of log confidentiality shall file the log with the commission immediately after the conclusion of the period for filing the request.

(e) Sanctions. If an operator fails to file a completion report or log in accordance with the provisions of this section, the commission may refuse to assign an allowable to a well, set the allowable for such well at zero, and/or initiate penalty action pursuant to the Texas Natural Resources Code, Title 3.
