Ariz. Admin. Code § 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.
