1509.10 Well log to be filed with division - contents - form.

(A) Any person drilling within the state shall, within sixty days after the completion of drilling operations to the proposed total depth or after a determination that a well is a dry or lost hole, file with the division of mineral resources management all wireline electric logs and an accurate well completion record on a form that is approved by the chief of the division of mineral resources management that designates:

(1) The purpose for which the well was drilled;

(2) The character, depth, and thickness of geological units encountered, including coal seams, mineral beds, associated fluids such as fresh water, brine, and crude oil , natural gas , and sour gas, if such seams, beds, fluids, or gases are known;

(3) The dates on which drilling operations were commenced and completed;

(4) The types of drilling tools used and the name of the person that drilled the well;

(5) The length in feet of the various sizes of casing and tubing used in drilling the well, the amount removed after completion, the type and setting depth of each packer, all other data relating to cementing in the annular space behind such casing or tubing, and data indicating completion as a dry, gas, oil, combination oil and gas, brine injection, or artificial brine well or a stratigraphic test;

(6) The number of perforations in the casing and the intervals of the perforations;

(7) The elevation above mean sea level of the point from which the depth measurements were made, stating also the height of the point above ground level at the well, the total depth of the well, and the deepest geological unit that was penetrated in the drilling of the well;

(8) If applicable, the type, volume, and concentration of acid, and the date on which acid was used in acidizing the well;

(9) If applicable, the type and volume of fluid used to stimulate the reservoir of the well, the reservoir breakdown pressure, the method used for the containment of fluids recovered from the fracturing of the well, the methods used for the containment of fluids when pulled from the wellbore from swabbing the well, the average pumping rate of the well, and the name of the person that performed the well stimulation. In addition, the owner shall include a copy of the log from the stimulation of the well, a copy of the invoice for each of the procedures and methods described in division (A)(9) of this section that were used on a well, and a copy of the pumping pressure and rate graphs. However, the owner may redact from the copy of each invoice that is required to be included under division (A)(9) of this section the costs of and charges for the procedures and methods described in division (A)(9) of this section that were used on a well.

(10) The name of the company that performed the logging of the well and the types of wireline electric logs performed on the well.

The well completion record shall be submitted in duplicate. The first copy shall be retained as a permanent record in the files of the division, and the second copy shall be transmitted by the chief to the division of geological survey.

(B)(1) Not later than sixty days after the completion of the drilling operations to the proposed total depth, the owner shall file all wireline electric logs with the division of mineral resources management and the chief shall transmit such logs electronically, if available, to the division of geological survey. Such logs may be retained by the owner for a period of not more than six months, or such additional time as may be granted by the chief in writing, after the completion of the well substantially to the depth shown in the application required by section 1509.06 of the Revised Code.

(2) If a well is not completed within sixty days after the completion of drilling operations, the owner shall file with the division a supplemental well completion record that includes all of the information required under this section within sixty days after the completion of the well.

(C) Upon request in writing by the chief of the division of geological survey prior to the beginning of drilling of the well, the person drilling the well shall make available a complete set of cuttings accurately identified as to depth.

(D) The form of the well completion record required by this section shall be one that has been approved by the chief of the division of mineral resources management and the chief of the division of geological survey. The filing of a log as required by this section fulfills the requirement of filing a log with the chief of the division of geological survey in section 1505.04 of the Revised Code.

(E) If there is a material listed on the invoice that is required by division (A)(9) of this section for which the division of mineral resources management does not have a material safety data sheet, the chief shall obtain a copy of the material safety data sheet for the material and post a copy of the material safety data sheet on the division’s web site.
