MEMORANDUM
TO: Weld County Commissioners:
David Long, Glenn Vaad, Rob Madsen, William Jerke, and Mike Geile
FROM: Brian Macke and Randall Ferguson
DATE: June 4, 2004
SUBJECT: Art Eskildsen Water Well Complaint#200029460
It was a pleasure to meet and talk with you all during lunch before our recent hearing in
Greeley on May 17, 2004. Thank you for providing the newspaper article regarding the
Eskildsen water well impact. Brad Turner, the reporter for the Daily Times-Call, had
previously been in the COGCC Public Room to review the extensive file on this
complaint.
This is an active and ongoing remediation project (No. 1587). The initial complaint from
Mr. Eskildsen was on March 10, 2002. It was reported that gas was present in both the
Art Eskildsen and the Bonnie Eskildsen water wells. Both water wells are completed in
the Laramie/Fox Hills aquifer. Based on laboratory analyses, the water wells had been
impacted by"thermogenic" methane. For your information, the gas produced from oil
and gas wells is"thermogenic" methane. Thermogenic methane gas is formed by the
thermal breakdown of organic material in rocks resulting from high temperatures created
by deep burial. "Biogenic" methane gas occurs in most near-surface environments and is
a principal product of the decomposition of buried organic material. In Weld County
many of the coal zones in the Laramie/Fox Hills aquifer contain biogenic methane gas.
The closest oiUgas well to the Eskildsen water wells is the Scheidt State VV 16-13
operated by Patina Oil & Gas Corp (Patina). During workover operations in March and
April of 2002, holes in the casing were found and subsequently repaired. Based on
available information and analytical evaluations, it was determined that the source of the
gas in the Eskildsen water wells was likely the Scheidt State VV 16-13 well. A Notice of
Alleged Violation (NOAV) was issued to Patina on June 19, 2002. Corrective action
included the submittal of a Form 27— Site Investigation and Remediation Workplan. The
submitted workplan was conditionally approved by the COGCC on December 27, 2002
(see attached copy). Also attached is a partial timeline of events provided by Patina that
was required by the COGCC with the submittal of the Form 27.

The Eskildsen water wells are being sampled by Patina on a quarterly basis. Laboratory
results are then forwarded to the COGCC for review. The well water is being pumped
into a storage tank where it is "de-gassed" prior to domestic use. During the summer, the
water is pumped from the well onto the Art Eskildsen property for irrigation purposes.
Deep Rock drinking water has been provided to the Eskildsen household by Patina since
April of 2002.
I hope that this summary of the complaint answers some of your questions and/or
concerns. Should you have any additional questions, please call Randall Ferguson at

RE: Scheidt State VV 16-13 /Remediation#1587
SWSW Section 16—T1N—R67W
Weld County, Colorado
Dear Mr. Cox:
As you are aware, a Notice of Alleged Violation (NOAV) was issued to Patina Oil& Gas
Corporation (Patina) on June 19, 2002. The NOAV required Patina to submit a Form 19—
Spill/Release Report and a Form 27—Site Investigation and Remediation Workplan for the
continued monitoring and abatement of the methane gas present in the Eskildsen water
wells. Please note that the NOAV had an incorrect date of December 27, 2001 for the
alleged violation. The correct date should be the date of initial sampling at the Art
Eskildsen water well,which is March 20,2002.
Most recently, additional sampling of the Eskildsen water wells was conducted on
September 5, 2002. The Art Eskildsen water well was also sampled on March 20 and July
29,2002. The Bonnie Eskildsen water well was also sampled on July 29, 2002. The
results of the gas composition and isotopic analyses indicated mixtures of thermogenic and
biogenic gas in both water wells. However,the gas in both water wells is different. All
analytical results from both water wells and other available data were provided to Anthony
Gorody,Ph.D.with Universal Geoscience Consulting, Inc. in Houston, Texas for further
evaluation.
Mr. Gorody concluded that the methane gas present in the Bonnie Eskildsen water is most
similar to the Codell gas that is produced in the Scheidt State VV 16-13. The methane gas
present in the Art Eskildsen water well has very different characteristics and Mr. Gorody's
attempt to determine the source of the small amounts of thermogenic gas in this well is not
conclusive. A copy of his evaluation is attached.
As previously reported, casing leaks were repaired in the Scheidt State VV 16-13 during
March and April of this year. Based on this and other analytical evaluations, Colorado Oil
& Gas Conservation Commission(COGCC) staff has determined that the potential source

of the gas in the Bonnie Eskildsen water well is most likely the Scheidt State VV 16-13 and
the gas in the Art Eskildsen water well also may be from this oil/gas well. Therefore,the
workplan is approved with the following conditions:
➢ Provide the COGCC with a chronology of all abatement measures and sampling
events undertaken by Patina at the Art Eskildsen and Bonnie Eskildsen water
wells.
➢ Gas meters were installed at the Eskildsen water wells by Patina as an abatement
measure to monitor the flow rate of gas from each well. Patina has periodically
monitored the meters and submitted the results to the COGCC on a bi-weekly
basis. Flow has not been recorded in either water well since July of 2002. It has
been reported that the meters may have been disconnected during well
maintenance and not properly re-connected. Patina shall confirm that both meters
are functioning properly by January 15, 2003 and report to the COGCC
accordingly. If the meters are not functioning properly, Patina shall schedule
repairs as soon as practicable and resume the periodic monitoring and submittal of
results. Should the current meters fail to adequately measure the flow rate of gas
from the Eskildsen water wells, Patina shall propose an alternative method of
monitoring.
➢ Patina shall sample for methane in water at both Eskildsen water wells. Water
samples shall be collected before entering the reserve tank and after exiting the
reserve tank to determine the general effectiveness of the de-gassing of the well
water. Laboratory results shall be submitted to the COGCC for review by January
15, 2003. Should methane concentrations not decrease appreciably after the
residence time in the reserve tank, additional abatement measures may be
required. Additionally, methane sampling shall be conducted monthly and the
results reported to the COGCC also on a monthly basis.
➢ Patina shall also sample for BTEX in water at both Eskildsen water wells. Water
samples shall be collected before entering the reserve tank. Laboratory results
shall be submitted to the COGCC for review by January 15, 2003. Additionally,
BTEX sampling shall be conducted monthly and the results reported to the
COGCC also on a monthly basis.
➢ Patina shall attempt to collect gas samples from both water wells on a quarterly
schedule. Each gas sample shall be analyzed for gas composition and isotopic
properties, including Delta C-13 of methane, Delta D of methane, DIC—
Dissolved Inorganic Carbon, and Delta C-13 of DIC. Laboratory results will be
evaluated to determine the status of biogenic and/or thermogenic characteristics.
➢ Patina shall provide adequate periodic inspections and maintenance of the
batement equipment to ensure that it is operating properly.
Mr.Mikel A. Cox
12/27/02

➢ Patina shall notify the COGCC at least 48 hours prior to each sampling event
required in this workplan approval.
Additionally, Patina submitted the Form 19 (Spill#01121148) and the Form 27
(Remediation#1587) as per the NOAV requirements. Therefore,the NOAV is hereby
resolved. Should you have any questions,please call me at(303) 894-2100 ext.118.

Eskildsen Project
March 10,2002—Roger Lowe met with Art Eskildsen to talk about flowline repair work
and past surface damages. It was brought to Roger's attention that Art had been
experiencing gas and or water bubbles in their water. Roger immediately notified John
Nussbaumer and Scott Reasoner.
March 10,2002 - Art Eskildsen's original complaint to the COGCC.
March 18,2002—Letter from the COGCC (Colorado Oil & Gas Conservation
Commission). The letter specified the Scheidt State VV 16-13 had a possible casing leak
and a water well in the area has possibly been contaminated as a result of the leak
March 20, 2002—John Nussbaumer met Randall Ferguson of the COGCC at the
wellsite. They took gas and water samples of the Scheidt State VV 16-13 and both
Eskildsen's water wells located in Township 1N, Range 67 W, Section 16 SWSW.
March 27,2002 —Moved in rigged upon the Scheidt State VV 16-13, found holes in
casing at 1,300'. Repaired holes in casing by doing an annular fill. 620 sacks of cement
pumped from 1593' to surface.
March 27, 2002—Patina obtained gas sample from Scheidt State VV 16-13 and sent to
Empact Analytical for compositional analysis
April 4, 2002—Cement was drilled out and a bond log was run showing good integrity of
cement. The 3 'A" casing was pressure tested to 500# for fifteen minutes. This pressure
test was witnessed by COGCC.
April 5,2002—Patina coordinated Deep Rock for drinking water for both Eskildsens.
April 12,2002—Patina contracted Boulder Water Well Service to set up fresh water
systems for both contaminated water wells.
April 22,2002—Gas meters were installed on wellheads so the gas production could be
monitored and recorded.
April 30,2002 —Patina obtained water samples from both wells and analyzed for BTEX
and TDS.
May 16, 2002—Patina paid $400 to Art Eskildsen for damages due to the casing repair
on the Scheidt State VV 16-13.
May 17, 2002 —Cleaned water tanks.
May 18, 2002—Problem with Art's fresh water pump. Boulder Water Well Service
changed out packing on centrifugal pump. Patina paid for repairs.
May 23, 2002 - Patina obtained water samples from both wells and analyzed for BTEX
and TVH.
May 28,2002—Patina received a copy of a letter from Randall Ferguson of the COGCC
to Art Eskildsen, which was a reply to Art's original complaint and an update of the
status of the tests.
June 4,2002 —Patina received a copy of a letter from Randall Ferguson of the COGCC
to Art Eskildsen with gas test results. The gas samples were analyzed for gas
compositional properties, isotopic properties, carbon 12 and 13, and hydrogen/deuterium.
Composition analysis from both water wells and the Scheidt State 16-13 were overlays.
Organic and inorganic analyses were conducted on water from the Eskildsen well.
Inorganic results were within normal ranges and BTEX results were non-detect.
Biological Activity Reaction Tests were also conducted. Iron related bacteria, sulfate
reducing bacteria, and slime forming bacteria were all present in the well.
June 11, 2002 —Cleaned water tanks
June 13,2002 —Patina paid $700 to Art Eskildsen for two ewes, 2 lambs, a calf and
garden hose.
June 19, 2002—Boulder Water Well Service diagnosed bad pressure tank from Art
Eskildson's original fresh water system. Tank was replaced along with additional float
switches. Patina paid for repairs.
June 19,2002 —COGCC issued NOAV.
June 20,2002 —Cleaned water tanks
June 24, 2002 —Mikel Cox and Randall Ferguson(COGCC)collected gas sample from
Scheidt State VV 16-13. The gas samples were analyzed for gas compositional
properties, isotopic properties, carbon 12 and 13, and hydrogen/deuterium.
June 30, 2002 —Float switch malfunction causing water to enter electrical system on
Bonnie Eskildsen's property. Dave Lillo arrived at 4:30 p.m. and made a call to Boulder
Water Well Service. Boulder Water Well Service arrived at 6:00 p.m. and found the float
not anchored properly, reanchored float and tested complete system. At 11:30 p.m. Dave
Lillo received a phone call from Bonnie's boyfriend. He stated they didn't have water to
the house and that none of the other problems from earlier had been resolved. He was
belligerent and appeared to be intoxicated. Dave Lillo met Boulder Water Well Service
back at the site at 1:00 a.m. and found system working properly. The only concern found
was slightly reduced water flow to the house. Dirty filters were changed out and it
appeared that the filters had not been changed for a very long time. Patina paid for
repairs.
July 10, 2002—File Spill/Release (Form 19) and Site Investigation and Remediation
Workplan (Form 27) with COGCC.
July 16, 2002—Bonnie Eskildsen called Dave Lillo and stated her and her boyfriend
would like to purchase a house in Loveland. After speaking with a real estate agent, it
was concluded she would not be able to get fair market value for her current residence
due to no potable water. Bonnie asked how long it would take to get water on the
property. Dave Lillo responded that it could take 3 months to 3 years at this point.
Bonnie stated that fair market value for her property is $253,000 and that she had a
person lined up to rent it for$1,500 per month, but declined after finding out about the
water problems. Dave Lillo told her that he would speak to his supervisors about the
situation and ended the conversation.
July 23, 2002 —Cleaned the Tanks and had conversation with Bonnie Eskildsen. Dave
Lillo told Bonnie Patina was looking into several options to get water to her property
including drilling a replacement water well on the northwest corner of her property. She
stated that a well could not be drilled in that area due to the septic system. That area of
the property is the leech field. She stated the only place to drill a well on her property is
the place it is right now. She continued to state she wants out of the whole situation, and
she has consulted an attorney. Bonnie stated she would rather not sue Patina at this point
due to the time constraints and Patina could settle out of court with her for$700,000.
July 26, 2002- Met w/Randall Ferguson
July 29, 2002 - Mikel Cox and Randall Ferguson(COGCC) collected gas sample from
both(Art& Bonne) water wells. The gas samples were analyzed for gas compositional
properties, isotopic properties, carbon 12 and 13, and hydrogen/deuterium.
