  1. PRC 421DECOMMISSIONING PROJECT JULY 2019 UPDATE CALIFORNIA STATE LANDS COMMISSION

  2. PRC 421 Piers and Wells Pier/Well #1 Pier/Well #2 2

  3. Plug & Abandonment of PRC 421-1 April 2019 • The 421#1 well was successfully plugged and abandoned to current standards. • The well served as a disposal well and that zone was plugged with cement in April by a coil tubing unit

  4. Safety Steps Prior to PRC 421-2 P&A • Prior to the actual work to P&A the wells, numerous safety measures were taken • The well cellars were replaced with fabricated steel walls • The wellhead valves were inspected, cleaned and replaced when necessary • Old wellheads and risers were cleaned and repaired

  5. PRC 421 Piers – The “Beachfront” Wells • Plugging & Abandonment • The 421#2 Well is still a work in progress • The well produced oil from the geologic Vaqueros formation from 1930 until it was shut in in the 1990’s, and that zone was plugged with cement in April 2019 as well. • In May more of the well was sealed using a small drill rig setting numerous solid cement and fluid barriers in the wellbore from the that zone up to approximately 1541 feet. • On May 28, 2019, while preparing for the surface cement plugs, there was a discharge of oil both inside and outside of the steel caisson. • The operation immediately shut down in order to respond to the discharge. A Unified Command was established.

  10. Unified Command and Collaboration • Unified Command Consisted of: • Department of Fish and Wildlife, Office of Spill Prevention and Response (OSPR) • Lt. Christian Corbo (OSPR) – State On-Scene Coordinator (SOSC) • Eric Laughlin – Public Information Officer • United States Coast Guard • CWO. Paul Ricketson – Federal On-Scene Coordinator (FOSC) • City of Goleta • Anne Wells – Advance Planning Manager, Department of Planning and Environmental Review

  11. Unified Command Cont’d • Unified Command Consisted of: • California State Lands Commission (Responsible Party) • Jeff Planck – Platform Holly/PRC 421 Project Lead • Seth Blackmon – Project Co-Lead • Jennifer Lucchesi – Executive Officer • Sheri Pemberton – Public Information Officer • Jennifer Mattox – Tribal Liaison • Beacon West Energy • Larry Huskins • Chris Peltonen • Keith Wenal • Mike Wracher

  12. Incident Response • May 28, 2019 • Krummrich Engineering notified Beacon West of the spill, initiating the emergency action / oil spill response plan • Beacon West set-up the ICS (Incident Command System) at MSRC (Marine Spill Response) • MSRC deployed a spill containment vessel to location and truck-based spill response equipment • Fire department, CSLC, and OSPR mobilized to location to complete site assessment • Representative from the City of Goleta present to assess site. • Representatives from local Tribes present to assess/observe response and protect potential cultural resources • May 29, 2019 – June 1, 2019 • Federal Fish and Wildlife Department and U.S. Coast Guard in charge of ICS • OSPR assessed 0.5 bbl of new oil over a 0.25 mile span of beach • Old oil prevalent on beach from Holly area seeps. • New oil distinguished from old oil by having slight sheen. • Beach areas further east of spill area were examined and no new oil reported • MSRC stood down on day two and returned to harbor after reporting no oil in the water. • Clean up crews using shovels and plastic bags dug up oily sand and picked up oily seaweed for three days. • Beach walk assessments completed and clean up operations discontinued on June 1.

  13. PRC 421-2 Discharge: What We Know and What We Don’t. We still have many questions as to the cause and the source of the oil, but the investigation is on-going. The oil discharged was not from the production zone which had been plugged with cement in April with the coil tubing unit (shown above re 421#1). Note: Produced oil was of a much different chemical make-up. The total discharge was estimated at 2-3 barrels (84-126 gallons) of “dead” oil (no sheen in the water, very thick and a slight sheen on the surface or in small tide pools). Lab indicated most likely oil weathered Vaqueros oil. The discharge was cleaned up quickly and efficiently in less than 5 days

  14. The Investigation Since the incident, we have investigated the inside of the caisson for oil (by coring) and have found no “free oil” (only oiled soil). Subsequent to that investigation, during a low-low tide episode, the beach was excavated next to the caisson where oil was seen during low tides. The excavation was performed under the oversight of the Unified Command and other interested parties. The investigation cleared the sand away from the caisson out to the point source of the oil. The excavation determined that the oil was not coming from under or out of the caisson but was coming through a breach in the bedrock. The bedrock here is the highly fractured Monterrey formation and it appears to be a natural conduit that may or may not be in contact with the well.

  15. Beach Excavation (7/3/19 2am-8am)

  16. 421-2 Current Well Status ?? • Vaqueros formation isolated with cement squeeze and balanced plug(in April) • 13-3/8” casing isolated below 1600’ • Cement inside 9” casing to 1541’ • 20” X 13 3/8” casing cemented by “top job” • Next steps (Unofficial): 3 100’ cement plugs inside the 9’ X 13 3/8” casing (suspected area of oil retention) • Then: Cut and recover 9” casing @430’; place CIBP on top of casing stub and cement inside 13 3/8” to surface Fresh Water

  17. Final Steps The method for the final plugging or “capping” of the well is being reviewed by DOGGR and SLC engineers and will proceed once everyone is satisfied that the activity will prevent or limit any further discharges. The Unified Command will continue to investigate. The final plug and abandonment should ensure that the well will not interact with the nearby seep in the future, but the final work may also push some oil in the seep to surface.   The Unified Command is developing mitigation measures to limit the risk and to immediately respond to any further discharge of oil to the beach.
