PURPOSE: A history of the production of an oil or gas well is important in the evaluation of a particular well, lease or pool. Reservoir characteristics, fluid behavior and production can be used for studies and estimates of production on future pools. Use of production data and reservoir analyses included on monthly reports can be correlated with recovery techniques to promote conservation and to prevent waste in the oil industry. This rule provides for the filing of monthly status, production and water disposal reports, with certain waivers. (1) Monthly well status and production report, approved form OGC-9, shall be prepared in full and submitted to the state geologist no later than thirty (30) days after the end of each calendar month. The status of each well on a lease is requested on a monthly basis. Production data may be presented by each lease unless requested otherwise by the council.

1. (2) Monthly report of injected fluids, approved form OGC-10, shall be prepared in full and submitted to the state geologist no later than thirty (30) days after the end of each calendar month. The method of disposal of all fluids produced from oil wells, gas wells, or enhanced recovery operations must be clearly stated. Water produced from underground gas storage reservoirs that is disposed of by injection is included.
2. (3) In the event monthly data requested by form OGC-9 are available on another format as a result of machine printout, the form may be accepted in lieu of form OGC-9, provided a written request, accompanied by a sample printout, has been submitted to the state geologist for his/her approval.
3. (4) Monthly well status and production reports may be waived by the state geologist upon application in the event that gas production by an owner is for his/her sole and private use.
4. (5) If mechanical failure of an injection well should occur or if other conditions should develop that threaten or could threaten to contaminate an aquifer, the operator or an authorized representative shall notify the state geologist as soon as possible by telephone and letter. The letter shall be complete and accurate and shall contain the operator’s estimate of the nature of the problem(s).
5. (6) The operator shall be required to monitor the injection pressure and injection rate on each injection well at least on a monthly basis, with the results reported annually on form OGC-12, to the state geologist.
6. (7) All monitoring reports will be on file at the office of the state geologist and will be retained and available for at least five (5) years.
