1.1.1 Incident Category

Discharging or Threatening to Discharge Abandoned Oil Production Wells

1.1.2 Site Description

In early 2009, the Oklahoma Corporation Commission (OCC) requested EPA-R6 assistance with abandoned oil production wells that were leaking crude oil in areas located near Lake Oologah and its tributaries. The wells were from leases that were initially part of Phase I of the Lake Oologah Oil Spill Project (Oologah Project) but were not addressed then because they were either part of an active lease or were secured at the time. With no viable responsible party (RP) after many years from the original project phase, EPA proceeded to address the wells by Plugging and Abandonment (P&A). After noticing the large number of wells now discharging or threatening to discharge crude oil, EPA conducted a re-assessment of all the wells that were not P&A within the previous Phases of the Oologah Project. The re-assessments were to determine if the wells were now discharging or threatening to discharge into navigable waters of the U.S. and adjoining shorelines.

During the winter of 2009-2010, EPA conducted a re-assessment of the wells within the Oologah Project database that were not P&A during previous phases and noticed that a substantial number of the wells were now discharging or threatening to discharge oil, unsecured, and potentially abandoned with no viable RP.

1.1.2.1 Location

The wells are located in the east side of Lake Oologah scattered within 21 Sections in Rogers and Nowata counties in Oklahoma. In specific, Sections 4, 5, 6, 8, 9, 16, 17, 20, 21, 28, 30, and 32 of Township (T) 24N, Range (R) 17E and Sections 23, 24, 25, and 26 of T 24N, R 16E, in Rogers County; and, Sections 16, 17, 28, 29, and 32 of T 25N, R 17E in Nowata County.

The Command Post for the project is located in Section 7 T 24N, R 17E, in specific 16510 A&B E 300 Road, Chelsea, Rogers Co., Oklahoma. The coordinates are Latitude 36.58018º N, Longitude 95.53283º W.

1.1.2.2 Description of Threat

The re-assessment revealed that most of the wells seemed to be abandoned and that equipment associated with production has been removed, leaving the wells unsecured and many of them substantially discharging oil onto the surrounding area. The wells that are not visually leaking are completely unsecured with crude oil measured inside the well within a close distance from the top of the casing. All the unsecure and/or leaking wells are located next or near to a ditch, ravine, or creek that drains directly to Lake Oologah within a short distance. Drainage throughout the project area is within 0 to 4 miles of and contiguous with the lake. Lake Oologah is a navigable waterway of the U.S. and a drinking water source for the city of Tulsa and other smaller municipalities in the area.

1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

Between November of 2009 and January of 2010, EPA conducted a comprehensive re-assessment of wells not P&A within Phases I, II, and III of the Oologah Project. After corroborating previous property access agreements, ground teams visited the sites using GPS coordinates already logged into the project database. The reassessment consisted of ground inspections of each site for visual observations, and determining the depth of fluids from the top of casing for those wells that a discharge was not apparent.

Close to 2,500 well sites within 36 Sections were visited and a substantial number of the wells are now actively discharging or threatening to discharge crude oil, unsecured, and potentially abandoned with no viable RP. Of those, 228 wells were identified to require some type of removal action (plugging or repairs). Based on observations and discussion with current owners and/or operators still producing oil in the area, about one half of those wells can be addressed by RPs. The rest appear to be abandoned with almost no possibility that a viable potential RP (PRP) could be found. As of April 2010, few smaller properties have not been reassessed yet for logistical reasons and the team decided to wait until the start of field activities (P&A) to resume the reassessment.

2. Current Activities

2.1 Operations Section

2.1.1 Narrative

From September 21 to November 19, 2010, EPA continued to address abandoned and unsecured or leaking oil wells within Rogers and Nowata Counties, Oklahoma. Oil wells without a viable RP are plugged and abandoned (P&A), which generally consists of filling well bore with cement to prevent oil from discharging onto the surface and into a navigable water body. In addition, EPA has coordinated clean-up of leaking oil wells with RPs.

2.1.2 Response Actions to Date

Between September 21 and November 19, 2010 EPA has addressed 20 abandoned oil wells within Rogers County of which 19 oil wells have been P&A and 5 oil wells required additional drilling. During this reporting period, the addressed oil wells are located in Sections 16-T24N-R17E, 30-T24N-R17E, and 7-T24N-R17E; or Project Areas (PAs) 25, 13, and 27.

Since initiation of P&A activities on April 20, 2010, EPA has addressed a total of 46 abandoned and unsecured oil wells within Rogers County. Of the 46 addressed oil wells, 41 oil wells have been plugged and abandoned and 5 oil wells that will require additional action to complete. The addressed oil wells are located within 4 Sections or PAs 5, 13, 25, and 27 (see uploaded maps for Section numbers/PA cross reference). In addition, EPA has coordinated with RPs the clean-up or remediation activities including the repair of leaking wells or securing those that are threatening to leak.

From 27 April and 07 September 2010, response activities were suspended for approximately 3 months to concentrate resources on the Deepwater Horizon Gulf Response. Also, inclement weather has caused some scheduled delays.

EPA and contractors demobilized for Thanksgiving holiday. P&A activities are planned to resume on 30 November 2010.

2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)

EPA continues to search for additional PRPs and to coordinate with active RPs to verify that their work to secure the wells within their responsibility is performed properly. As of today, seven RPs or active operators have been identified that are working to secure their wells that were identified by EPA during the reassessment.

Upon returning to the site after the break on September 7, EPA noticed that several of the identified viable RPs have secured and cleaned up most of the wells under their responsibility. OSC Bernier is in the process of coordinating with those RPs for them to provide final completion report for our records and conduct final inspection of the RP wells. As of November 19, RPs with problem wells within PAs 19, 24, 25, 26, 27, 28, 30, 31, 32, 41, and 42 have continue their efforts to correct or secure the wells and prevent a discharge of oil. Around 45 wells have been P&A or repaired and/or secured by these RP as part of the coordinating efforts with EPA.

Also, EPA has sent Notice of Federal Interest letters to a recently found PRP for unsecured and/or leaking oil wells in an oil lease within PAs 29 and 32. There is a significant number of wells within this lease that meet the project criteria to be P&A by EPA. Over the past several years, the oil lease has been owned and/or operated by several entities with no clear, official, or definitive title to own or operate the lease. A recent court order granted cost recovery to one of the PRPs. EPA is working closely with the State to determine if in fact there is a viable RP for this lease.

2.2 Planning Section

2.2.1 Planned Response Activities

Continue to address unsecured and abandoned oil wells.
Continue to coordinate clean-up activities of leaking oil wells with RPs.
Conduct assessments to locate unsecured and/or leaking oil wells within a few additional properties in 5 Sections/Project Areas.
Conduct RP research on leaking oil wells to locate viable RP, as needed.

2.2.2 Next Steps

On November 29, 2010, project personnel plan to re-mobilize back to the site after the Thanksgiving break to resume P&A activities. EPA plan to complete the remaining 5 oils wells that have been addressed and move P&A activities to PA 24 or Sec 17 T24N R17 E in Rogers County.

2.2.3 Issues

Because of inclement winter weather, it is expected for field activities to have some schedule delays due to accessibility issues for heavy equipment and for safety reasons.
