Ariz. Admin. Code § 12-7-116

Current through Register Vol. 30, No. 50, December 13, 2024

Section R12-7-116 - Multiple Zone Completions

A. Completions to include production from more than one common source of supply from a single well are prohibited except as authorized by the Commission after notice and hearing. After notice and hearing, the Commission shall maintain a list of zones or reservoirs, by fields, for which multiple completions have been authorized.

B. Operators shall file an application for multiple completion with the Commission and shall demonstrate the method to be used to keep the production streams separate. The application shall be accompanied by:

1. An electrical log or other acceptable log with tops and bottoms of formations or producing zones and perforated intervals shown and marked;

2. A diagrammatic sketch of the multiple completion installation indicating make, type, and setting depths of packer or packers;

3. A plat showing the location of the well and all offset wells and the names and addresses of operators of all leases offsetting acreage dedicated to applicant's well; and

4. Proof of mailing of application for multiple completion to all offset operators.

C. The Commission may approve subsequent applications for multiple completion of the same zones or reservoirs in a field administratively without a hearing, provided that:

1. The applicant can show that the Commission has approved and listed the zones or reservoirs as required in subsection (A);

2. The subsequent application is filed as required in subsection (B); and

3. The Commission receives no protest to the application after a 15-day holding period. A hearing shall be called if a protest is received.

D. Within 15 days of setting the final packer or packers, the operator shall file a report with the Commission identifying the well and its location showing the make, type, and depth set of each packer and the signature of the supervisor of the work. This report shall include the results of a packer leakage test and detail for each separate common source of supply, its stabilized shut-in pressure, producing pressure, and the simultaneous shut-in pressure on each other separate common source of supply. The operator shall notify the Commission at least 48 hours in advance of performing the tests required in this subsection.

E. Every operator of a multi-completed well shall operate, produce, and maintain the well to prevent commingling of production from the separate sources of supply. The Commission may require any multi-completed well to be tested at any time to demonstrate the effectiveness of the separation of sources of supply. These tests may be witnessed by representatives of the Commission and by offset operators.
