There are four abandoned oil wells and one tank located on Mountwood Park in Parkersburg, WV. These wells have been leaking into the Walker Creek which is a tributary to the Ohio River.
a. During the week of May 17, 2004, WVDEP and its contractor performed emergency containment around the wellheads. WVDEP's surveyor completed surveying activities at the wells.
b. WVDEP and its contractor began to construct access to the well locations during the week of May 24, 2004. Mobilization of equipment to the site entrance was performed.
c. The contractor completed building site access on June 2, 2004, and rigged up on well #3. The contractor pulled 490 feet of sucker rods from the wellbore. On June 3, 2004, the contractor built a plugging pit, pulled the tubing from the wellbore, and completed cementing the well to the surface. The cement depth was checked at 45 feet on June 4, 2004, the well was cemented to the surface, and the monument was set. The contractor emptied the contents of the 100-barrel tank that was present on site and disposed of the fluids. The contractor removed the tank from the site. The contractor rigged up on well #1 on June 4, 2004, and pulled sucker rods and tubing from the wellbore. The contractor set the bottom cement plug in the wellbore and shut down for the weekend.
d. During the week of June 7, 2004, the contractor recovered the 7-inch casing from the wellbore of well #1, but could not recover the 10-inch casing. The contractor cemented the wellbore to the surface and set the monument on well #1 on June 8, 2004. The contractor then rigged up on well #2 and pulled approximately 1,394 feet of tubing from the wellbore. Due to the depth of the wellbore, the parted casings, and the presence of bridges in the wellbore the contractors required three days to complete circulation and attempted casing recovery from the wellbore. A portion of the 7-inch casing (204 feet) was recovered, but none of the 10-inch casing could be recovered. The well was cemented to the surface and the monument was set on well #2 on June 11, 2004. Also during this week, the contractor worked on site construction of location #4.
e. During the week of June 14, 2004, the contractor rigged up on well #4 and pulled 310 feet of tubing from the wellbore. The contractor recovered all of the 198 feet of 7-inch casing from the wellbore. The 10-inch conductor pipe was also recovered. The contractor cemented the wellbore to the surface on June 17, 2004, and set the monument on well #4. The contractor worked on reclamation at all of the locations during this week. Heavy rains prevented completion of reclamation of the access road to the site.
f. WVDEP and its contractor completed reclamation at the site on June 21, 2004, and demobilized all equipment from the site.
g. Under the direction of OSC Kelly, START periodically visited the site in order to monitor plugging operations and correspond with WVDEP. START conducted photographic and written documentation of site activities.
Removal actions at the site have been completed.
A. Under the direction of OSC Kelly, START will complete the After Action Report for the site, including completion of a PRP investigation for the abandonment of the wells.
b. Upon completion of the After Action Report, OSC Kelly will review the documentation and submit the report to the USCG for WVDEP reimbursement.
Four wells were leaking into the Walker Creek which leads into the navagible waters of the Ohio River.
