Section 312 IAC 29-22-6 - Well stimulation treatment plans for operations using 5,000 barrels or more of total fluidAuthority: IC 14-10-2-4; IC 14-37-3
Affected: IC 14-37
Sec. 6.
(a) Every well stimulation using a total of five thousand (5,000) barrels or more of stimulation fluid shall have a well stimulation plan prepared according to the requirements of this section. The plan shall be: (1) prepared and signed by an authorized representative of the well owner or operator experienced in the design and conduct of well stimulation treatment operations;(2) available on the site during well stimulation; and(3) available for inspection or copying by the division upon request for a period of twelve (12) months after the conclusion of well stimulation on the well for which the plan was prepared.(b) Before initiating well stimulation operations, all employees, agents, contractors of the owner or operator, or other persons involved with conducting the well stimulation shall receive awareness training regarding the contents of the plan.(c) The well stimulation plan required under this section shall include, at a minimum, the following information:(1) The age and specifications for surface casing, production casing, and well head equipment installed on the well.(2) Verification of the adequacy and integrity of cement behind each casing string to ensure isolation of well stimulation fluids.(3) Identifying whether well stimulation will be conducted through a frac string on packer or through the production casing. (4) Describing whether the use of a well head isolation tool or tree saver is warranted to ensure protection of well head and casing and to comply with the requirements of this rule.(5) Specifying the maximum design surface pressure and measures to be taken to protect against overpressure conditions that could result in failure of well casing strings or well head equipment.(6) Providing a plan for continuous monitoring during well stimulation of surface injection pressure, injection rate, and annuli pressures.(7) Describing the proximity, condition, and potential impact of the well stimulation on nearby existing and previously plugged oil or gas wells.(8) Identifying the intervals to be treated.(9) Disclosing the volumes and composition of well stimulation fluids and proppants, if used.(10) Confirming that sufficient storage tank capacity exists to contain anticipated frac flow-back fluids.Natural Resources Commission; 312 IAC 29-22-6; filed 12/1/2017, 10:35 a.m.: 20171227-IR-312160230FRAReadopted filed 1/17/2023, 1:53 p.m.: 20230215-IR-312220328RFA
