TITLE 62: MINING
CHAPTER I: DEPARTMENT OF NATURAL RESOURCES
PART 240 THE ILLINOIS OIL AND GAS ACT
SECTION 240.780 REPORTING REQUIREMENTS FOR CLASS II UIC WELLS
Section 240.780 Reporting Requirements for Class II UIC Wells
a) Well Completion Reports
The Well Completion Report shall be completed on a form prescribed by the Department and shall contain:
A) the name and location of the well;
B) information on the construction of the well;
C) information on the injection zones and the type of completion treatment performed on each zone; and
D) injection rates, injection pressures and type of injection fluid.
2) Newly drilled or converted wells
A Well Completion Report shall be submitted to the Department within 30 days after the conclusion of initial completion activities (i.e., setting of tubing and packer) or within 30 days after the expiration of the permit if the well was not drilled or converted.
3) Existing wells
A Well Completion Report shall be completed and submitted to the Department for each recompletion of any existing injection well. Recompletion includes injection into a zone not previously used for injection in the well. The Well Completion Report shall be submitted within 30 days after the completion of any such workover or recompletion activity.
b) Well Drilling Report
1) For all wells drilled or deepened, a Well Drilling Report shall be completed by the permittee on a form prescribed by the Department.
2) The Well Drilling Report shall be submitted to the State Geological Survey within 90 days after drilling ceases and shall contain:
A) the name and location of the well;
B) drilling information;
C) the geologic names and depths of the formations encountered in drilling the well;
D) the results of all drill stem tests; and
E) a copy of the drilling time or geolograph record if a geophysical log was not run, unless the well is drilled with air rotary tools.
3) Well Drilling Reports are not required for well conversions not entailing a deepening of the well.
c) Geophysical Logs
A copy of all open hole wire line or geophysical logs run on the well shall be submitted to the State Geological Survey within 90 days after drilling ceases but, in the case of a conversion of an existing well, only if the well is deepened.
d) Drill Cuttings
1) Notification and Collection of Drill Cuttings
The Department shall notify the permittee when cuttings are required to be collected. Drill cuttings shall be collected for each run drilled in cable tool wells and each 10 feet of distance drilled in rotary or air drilled wells. The permittee shall obtain containers for the cuttings, and deliver the cuttings to the Illinois State Geological Survey in Champaign, Illinois. When cuttings are required, a Drilling Time log shall also be submitted.
2) When Drill Cuttings Required
Drill cuttings shall be submitted for each well when drill cuttings have not previously been submitted from any well within ½ mile of the newly permitted well. If the newly permitted well is drilled to a depth greater than any other well within ½ mile, drill cuttings shall be requested from the approximate previously submitted depth to the total depth in the newly permitted well.
e) Annual Well Status Report
The permittee of each Class II UIC well shall file an Annual Well Status Report on forms prescribed by the Department. The report shall be filed by May 1 of each year for the preceding calendar year for all wells which have not received Department approval for temporary abandonment or been plugged by the end of the reporting year, and shall include:
1) the name and location of the well;
2) the names of all injection intervals;
3) the setting depth of the packer; and
4) the average and maximum monthly injection rates and pressures.
f) Annual Enhanced Oil Recovery Project Report
The operator of an enhanced oil recovery project shall complete an annual project report on forms prescribed by the Department and submit the report to the State Geological Survey by May 1 of each year.
