Mike Subject: RE: UIC disposal well data for Illinois

Lisa,

Sorry for the delay, we have 1054 active(A) and 44 temporally abandoned(TA) wells classified as Salt Water Disposal. We also have 6635 A and 326 TA wells classified as Enhanced Recovery. Each year we

collect the OG

- 18 “Annual Class II Well Report” which identifies the Average Daily Injection Rate and Maximum Injection Pressure. These forms are due by June of each year and are reviewed for pressure and rate compared to the permitted maximums. If the Max is not exceeded the form is recorded as received, If the well exceeds either condition a notice of non

- compliance or notice of violation is issued.

We do not record any data from the forms, they are imaged and forwarded to the Illinois Geologic Survey (IGS).

There is a second form that is collected annually is the OG

- 17 “Secondary/Tertiary Oil Recovery Project Annual Report For the Year Ending ____” . This Form is collected by the IGS and collects info on the Enhanced Recovery only. If you are interested in water used in the enhanced recovery operations I would suggest contacting Bryan Huff at huff@isgs.uiuc.ed u 

### or at 217 244

- 2430.

If you are only looking for Disposal Operations, the information is held in our imaged records, but not in

an accessible database.

Hi Doug, I am following up to the voice message I left you this afternoon (my original email is below for reference). As I mentioned on the voice mail, we are looking for some data on the total number of Class II disposal wells in Illinois. Where available, we would be interested in the following data for Class II disposal wells in IL:

**•** Total number of active disposal wells,

**•** Historical daily dispos al well rates (bpd/well), and/or

**•** State daily disposal volumes (MGD).

Thanks again for your help,Lisa

Hi Doug, I work for the U.S. EPA’s Office of Water. I got your contact information from Tim Elkins and Krista McKim in EPA Region 5. Krista is part of our workgroup where we are working on developing a
pretreatment stan dard for unconventional oil and gas extraction wastewater. As part of the regulatory development process we are compiling background information on how oil and gas wastewater is managed in many states. We’ve obtained this information from various sources i ncluding state sources and publications, data purchased from a company that compiles information on wells (Drilling Info), and the literature. In compiling this information we identified a few gaps in our data. The gap we believe you could help with is dat a related to UIC disposal wells within the state of Illinois. Specifically what we are looking for are counts of the total inventory of Class II disposal wells in Illinois. Where available, we would also be interested in the following data for disposal we lls in IL: total number of active disposal wells, historical daily disposal well rates (bpd/well), and state daily disposal volumes (MGD). Would you be able to help us with this data need? Or direct us to someone who can?

Thank you,

Lisa
