Section 2 CCR 404-1-1313 - OPERATIONS AND REPORTING

a.Form 7G, Deep Geothermal Operator's Monthly Report of Operations. Operators will report all existing Deep Geothermal Wells that are not Plugged and Abandoned on the Form 7G, Deep Geothermal Operator's Monthly Report of Operations within 45 days after the end of each month.

(1) Operators will report a Deep Geothermal Well every month from the month that it is spud until it has been Plugged and Abandoned and reported for one month as abandoned. In addition to their producing and injecting and Plugged and Abandoned Wells, Operators will identify and list all drilling, Shut-In Wells, Suspended Operations, Temporarily Abandoned Wells, and Waiting on Completion Wells on their Form 7G reports.

(2) Operators will report each formation that is completed in a Deep Geothermal Well every month from the time that it is completed until it has been abandoned and reported for one month as abandoned.

(3) Operators will report the volume and disposition of Geothermal Fluids produced from a Deep Geothermal Well within 45 days after the end of each month. The reported volumes will include all Fluids produced during Flowback, initial testing, Completion, and production of the Deep Geothermal Well or Geothermal Injection Well. Produced fluids include, but are not limited to, produced water and fluids recovered during drilling, casing cementing, pressure testing, Completion, workover, and formation stimulation of all Deep Geothermal Wells including production, exploration, injection, service and monitoring wells.

(4) Operators will report the volume of any Fluids injected into a Geothermal Injection Well within 45 days after the end of each month. Any added fresh or recycled water, including but not limited to "makeup water" described in Rule 1312.h.(2), will be reported separately. The Operator will also report the source(s) of such water.

(5) Operators will report surface temperature and flow rate readings of Geothermal Fluid as near as practicable to the wellhead of a Deep Geothermal Well.

(6) For any Closed-Loop Geothermal System, Operators will report volumes and percentages of Fluid lost to the subsurface.

(7) Operators will measure and report Fluids and Geothermal Fluids in accordance with Rule 431.a.

b.Form 4, Sundry Notices. Deep Geothermal Operators are subject to the provisions of Rule 404.a. and d.

(1) Deep Geothermal Operators will comply with Rule 1302.a. for any Form 4 submitted to propose a change to an approved permit for Deep Geothermal Operations.

(2) Deep Geothermal Operators will comply with Rule 1305.a. for any Form 4 submitted to propose a change to an approved Form 2G associated with a Deep Geothermal Location or Facility.

(3) When amending a Form 2A previously approved for Oil and Gas Operations to include Ancillary Heat Production of Geothermal Resources, the Operator will submit a Form 4, Sundry Notice proposing such change to the approved Oil and Gas Operations, unless the Operator proposes to deepen, re-enter, or recomplete a Well to facilitate Ancillary Heat Production, in which the Operator will comply with Rule 308.

c.Form 42, Field Operations Notice. Deep Geothermal Operators will comply with the provisions of Rules 405.a.-r. and 405.t.

d.Deep Geothermal Location Construction. Deep Geothermal Operators will comply with the provisions of Rules 406 and 407.

e.Deep Geothermal Drilling Rules. Deep Geothermal Operators will comply with the provisions of Rule 408.a.- e., 408.g. - p. and Rule 408.r.- aa.

(1)Cementing. Deep Geothermal Operators will comply with Rule 408.f; alternative cementing methods must be approved in writing by the Director or Commission.

A. To request approval of an alternative cementing method in the permit application for Deep Geothermal Operations, the Deep Geothermal Operator will describe the proposed alternative cementing method in its Form 2 required by Rule 1305.b.(2).

B. To request approval of an alternative cementing method after approval of the Form 2, the Deep Geothermal Operator will submit a Form 4 describing the proposed alternative cementing method.

C. As to both Rule 1313.e.(1).A. and B., the Director or Commission can request, and the Deep Geothermal Operator will provide, any additional information the Director or Commission consider necessary to adequately assess the proposed alternative cementing method.

f.Directional Drilling. Deep Geothermal Operators will comply with the provisions of Rule 410.a.-c.

g.Public Water System Protection. Deep Geothermal Operators will comply with the provisions of Rule 411.

h.Surface Owner Notice. Deep Geothermal Operators will comply with the provisions of Rule 412.b.

i.Form 5, Drilling Completion Reports. Deep Geothermal Operators will comply with the provisions of Rule 414.

j.Form 5A, Completed Interval Report. Deep Geothermal Operators will submit a Form 5A, Completed Interval Report for a Deep Geothermal Well within 30 days after Completion of the Deep Geothermal Well. The requirements of Rule 416.b. and c. are applicable to Form 5As submitted for Deep Geothermal Wells.

k.Mechanical Integrity Tests and Bradenhead Monitoring.

(1)Mechanical Integrity Tests for Geothermal Injection Wells.

A. Deep Geothermal Injection wells are subject to Rule 417.a.

B. All Deep Geothermal Wells are subject to Rule 417.b-g.

(2)Form 21, Mechanical Integrity Test. Deep Geothermal Operators will comply with Rule 418.

(3)Bradenhead Monitoring. Deep Geothermal Operators will comply with Rules 419 and 420.

l.Statewide Floodplain Requirements. Deep Geothermal Operators will comply with Rule 421.

m.Welfare Protection Standards. Rules 422, 423, 424, 426, and 427 apply to Deep Geothermal Operations.

n.Well Control. Deep Geothermal Operators will comply with Rule 428.

o.Measurement and Reporting of Produced, Reused, Recycled, and Injected Water. Deep Geothermal Operators will comply with Rule 431.a.-b. In the context of Deep Geothermal Operations, Rule 431.a.-b. apply to all Deep Geothermal Wells including Geothermal Injection Wells. In addition to the requirements of Rule 431.a.-b., when reporting fluid volumes on the Form 7G, Deep Geothermal Operators will also calculate volumes in gallons and acre-feet.

p.Abandonment. Deep Geothermal Operators will comply with Rules 434.a., 434.b., 434.c.(2).A.i., 434.c.(2).B., 434.c.(2).C., and 435.
