1 | | established by administrative rule. |
2 | | (b) The owner or operator shall provide geological names, a |
3 | | geological description, and the depth of the formation into |
4 | | which well stimulation fluids were injected. |
5 | | (c) The owner or operator shall provide detailed |
6 | | information to the Director concerning the base stimulation |
7 | | fluid source. The owner, operator, or service company shall |
8 | | also provide to the Director, for each stage of the well |
9 | | stimulation program, the following: |
10 | | (1) each stimulation fluid identified by additive |
11 | | type; and |
12 | | (2) the chemical compound name and Chemical
Abstracts |
13 | | Service (CAS) number for each additive used. |
14 | | (d) The owner or operator shall also provide a detailed |
15 | | description of the well stimulation design, which shall |
16 | | include: |
17 | | (1) the surface treating pressure range; |
18 | | (2) the maximum injection treating pressure; and |
19 | | (3) the estimated or calculated fracture length and |
20 | | fracture height. |
21 | | (e) The Department shall post the information that it |
22 | | receives under subsections (b), (c), and (d) on its Internet |
23 | | website for a period of not less than 5 years. |
24 | | (f) The injection of volatile organic compounds, such as |
25 | | benzene, toluene, ethylbenzene, and xylene, also known as BTEX |
26 | | compounds, or any petroleum distillates, into an underground |
|
| | 09700HB2808ham001 | - 3 - | LRB097 02883 CEL 53667 a |
|
|
1 | | source of drinking water is prohibited without exception. The |
2 | | proposed use of volatile organic compounds, such as benzene, |
3 | | toluene, ethylbenzene, and xylene, also known as BTEX |
4 | | compounds, or any petroleum distillates, for shale gas |
5 | | extraction using hydraulic fracturing into hydrocarbon bearing |
6 | | zones is only authorized with prior written approval of the |
7 | | Director. Produced water containing trace amounts of naturally |
8 | | occurring petroleum distillates may be used as a stimulation |
9 | | fluid in hydrocarbon-bearing zones. Criteria for the |
10 | | authorization shall be established by the Department by rule. |
11 | | (g) In addition to any other information that it must |
12 | | provide, the owner, operator, or service company shall provide |
13 | | the Director the following post well stimulation detail: |
14 | | (1) the actual total well stimulation treatment volume |
15 | | pumped; |
16 | | (2) detail as to each fluid stage pumped, including |
17 | | actual volume by fluid stage, proppant rate or |
18 | | concentration, actual chemical additive name and type; |
19 | | (3) the actual surface pressure and rate at the end of
|
20 | | each fluid stage and the actual flush volume, rate, and |
21 | | final pump pressure; and |
22 | | (4) the instantaneous shut-in pressure, and the actual
|
23 | | 15-minute and 30-minute shut-in pressures when these |
24 | | pressure measurements are available. |
25 | | (h) During the well stimulation operation, the owner or |
26 | | operator shall monitor and record the annulus pressure at the |
|
| | 09700HB2808ham001 | - 4 - | LRB097 02883 CEL 53667 a |
|
|
1 | | bradenhead. If intermediate casing has been set on the well |
2 | | being stimulated, then the pressure in the annulus between the |
3 | | intermediate casing and the production casing shall also be |
4 | | monitored and recorded. A continuous record of the annulus |
5 | | pressure during the well stimulation shall be submitted. |
6 | | (i) If, during the stimulation, the annulus pressure
|
7 | | increases by more than 500 pounds per square inch gauge (psig) |
8 | | compared to the pressure immediately preceding the |
9 | | stimulation, then the owner or operator shall verbally notify |
10 | | the Director as soon as practical but no later than 24 hours |
11 | | following the incident and must complete in a timely manner any |
12 | | corrective action identified by the Department. The owner or |
13 | | operator shall include a report containing all details |
14 | | pertaining to the incident, including corrective actions |
15 | | taken. |
16 | | (j) The owner or operator shall provide information to the |
17 | | Director as to the amounts, handling, and, if necessary, |
18 | | disposal at an identified appropriate disposal facility, or |
19 | | reuse of the well stimulation fluid load recovered during flow |
20 | | back, swabbing, or recovery from production facility vessels. |
21 | | Storage of that fluid shall be protective of an underground |
22 | | source of drinking water as demonstrated by the use of either |
23 | | tanks or lined pits. |
24 | | (k) Nothing in this Section shall be construed to allow the |
25 | | Director to require the disclosure of trade secrets as defined |
26 | | in the Illinois Trade Secrets Act. |
