Beginning January 1999 the COGCC production reporting requirements were substantially changed. Production shall be reported for each completed formation in every well. Additionally, operators shall report all oil and gas wells that exist and are not plugged and abandoned on the "Monthly Report of Operations", Form 7. A well must be reported from the month that it is spudded until it has been reported for one month as abandoned. Every formation that is completed in a well shall be reported from the time that it is completed until it has been abandoned and reported for one month. Every well is uniquely identified by its API number and each completion is identified by the COGCC Formation Code for the completed formation name. The "Monthly Report of Operations", Form 7 is due forty-five (45) days following the end of the month that is being reported, For example, the report for January 1999 is due by March 17, 1999.

An operator may submit a single report that includes as many continuation pages as is necessary to report all wells and their completions. Wells used for injection whether it is disposal of produced water or fluids used in enhanced recovery unit operations are to be reported on the Form 7. Any fluids injected other than produced water or fluids used in enhanced recovery operations are to be reported on the "Monthly Report of Fluids Injected", Form 14.

All Form 7 revisions must be submitted in the format in which they were originally submitted. Any revisions prior to January 1999 shall be submitted on the previously used Form 7 that reported production on a lease basis. Forms must be marked as a revision and all the data for the lease or well completion must be submitted.

Every operator in the state is required to register with the COGCC. Upon registration operators are assigned a unique COGCC Operator Number. This operator number is required on all COGCC reporting. A suffix designation will be assigned for any regional office(s) listed on the Form 1, Registration of Operators. This suffix may be used in conjunction with the operator number to identify where the report originates and where any correspondence pertaining to the report should be sent; it is not a mandatory item.

The API number for a well is a national standard to uniquely identify all oil and gas wells, and wells associated with oil and gas operations.

Colorado State Code         Weld County Code              Sequence Number                          Sidetrack

The API number used to report will not include the state code "05". On the report the number should be provided as a single number including leading zeros in the sequence and sidetrack numbers; for example, 1230685700.

A sidetrack is any wellbore that extends from the originally drilled wellbore. A well may have more than one actively producing sidetrack.

COGCC has implemented five character formation codes which are used to abbreviate formation names including various formation combinations. Each completed formation is to be reported separately even if it is commingled down hole. Commingled formations should have allocated volumes reported that best reflect the operator’s knowledge of the estimated production attributable to each commingled formation. However, certain formations have long been listed as a common source of supply and may be reported as a single completion.

Table of common source of supply formations:

Each line of data shall include a status code.

Oil and water production are both reported in Barrels (bbls) which is equivalent to forty two(42) U.S. gallons adjusted to sixty (60) degrees Fahrenheit.

Oil adjustments are reported in Bbls and should reflect how the volume affected the tank. In other words if the volume in the tank was dropped because of the adjustment then the value will need to be reported as a negative number (e.g. water is drained from the tank bottom). An example of a positive adjustment would be hot oil recovered, this might also be reported in a following month when the oil is sold and it should not be counted as royalty sales.

In order to establish that oil production and sales data are correct it is necessary to run a balancing equation. In order to perform this equation it is necessary for the operator to provide a Beginning of Month (BOM) and End of Month (EOM) inventory. This value should be an allocated volume based on the each contributing completion in the stock tank. The equation used by the COGCC to validate balancing will be: BOM + Produced - Sold ± Adjustment = EOM.

No inventory is allowed for gas production. Gas volumes will be balanced by this equation: Produced = Flared + Used + Shrinkage + Sold.

The quality of the products sold shall be monitored and reported on each report. For oil sales the quality value shall be its specific gravity and for gas sales the quality value shall be its BTU content per MCF. This value should be the weighted average of the oil runs made in the month or the last gas analysis value.

All produced waters shall be reported on the From 7. The method of water disposition is to be reported by a single character code.

Operators are encouraged to report using electronic methods to eliminate paper work and to greatly streamline the process of data submittal and processing for both the operator and the COGCC. Below is a table describing the data fields on the Form 7 and the order that they need to appear in the electronic data file. Each well completion shall consist of a complete line of data with each field separated by a comma. In order to maintain sequence each data field must be accounted for even if it is null. Do not insert zeros for null values, i.e. if the well is shut in then there should be null values in the production data fields. Files should be submitted with a ".csv" extension the rest of the file name is not critical. There is no cover page or submittal page requirement. Electronic submissions may be made via removable storage media, 3.5" floppy disk or cd rom, or by email; the email address is "ogcc.eforms@state.co.us".
