  1. Welcome! CAVU Energy Services Presents The FILO SWD #1 Commercial Disposal Well Presented by: Mr. Billy Robinson Dr. Marian SmithDr. Bruce Langhus

  2. CAVU Energy Industries Founded in Tulsa, Oklahoma Innovative Management of Oil and Gas Waste Water FILO SWD #1 Well will inject produced salt water from area oil wells into the deep Arbuckle Formation on a vacuum

  3. Garvin County Oil and Gas BusinessTotal producing wells in Oklahoma: 84,000 Total injection wells in Oklahoma: 31,000 Total wells in Garvin County: 6,026 Total injection wells in Garvin County: 1,044 Total commercial disposal wells: 13 Disposal depth range: 1850’ to 7255’ Permitted disposal rate per day: 86,500 bbls Actual daily disposal rate in 2010: 5,300 bbls Max. actual inj. press. ranges from 1,800 psi to 0 psi Date of oil and gas drilling: 1938 to now

  4. Waste Water Injection and Oklahoma’s Oil Industry Oklahoma produces 22 times as much water as oil – there is no alternative. To maintain the state’s oil and gas industry, produced water must be managed safely and economically. Produced salt water is toxic to plants and must be removed from the environment.

  7. Arbuckle Injection Zone Regionally the Arbuckle contains a thick zone of fractured, vugular, occasionally cavernous porosity. This zone is widely connected over large areas, leading to massive, interconnected salt water reservoirs. Conservative estimates give the Arbuckle huge capacity to hold water:

  8. Class II (Oil & Gas Wastes) Injection Wells Highly regulated by OCC and EPA Include water-flood, private, and commercial disposal wells Commercial wells most highly regulated Eligible wastes are closely monitored

  9. Wastes Eligible for Disposal into Oklahoma’s Commercial Class II Wells • Water and solids produced from oil and gas wells • Spent chemicals used to treat wells that have been flowed back to the surface • Wastes taken from tanks or pipelines at the well • De-hy and de-sulfur treatment wastes at the well • Soil and surface water at the well-site contaminated by produced material such as salt water and/or crude oil

  10. Wastes Eligible for Disposal into Oklahoma’s Commercial Class II Wells: Naturally Occurring Radioactive Material • Regulated by the Oklahoma Department of Environmental Quality and enforced by the Oklahoma Corporation Commission. • NORM Liquids and slurries are eligible for disposal down Class II wells, regardless of concentration,if the wastes came from an oil and gas well.

  11. CAVU FILO SWD #1 – Geology Located in the East-Central portion of Garvin County, the proposed well will inject into the deep Arbuckle Formation. Several higher zones produce hydrocarbons in the area. Seismicity has not been an issue in the county with USGS hazard map showing Garvin to be quiet.

  12. CAVU FILO SWD #1 Inherent Safeguards Double layers of steel pipe and cement to protect ground water. Injection zone almost 4,000 feet beneath ground water supply. Cement, double layers of steel pipe, and monitoring annulus prevent leaks and spills. Geological sealing zones and intercept zones above injection zone prevent vertical migration of waste water away from well.

  13. CAVU FILO SWD #1 No evidence of faulting at the surface in Garvin County OKLAHOMA SURFACE GEOLOGY with FAULTS http://mrdata.usgs.gov/sgmc/ok.html

  14. Seismic RiskFILO SWD #1 will be one of many disposal wells in the US; the great majority are not associated with earthquake activity. State of Ohio has recently addressed induced seismicity from injection wells and has established eight rules to mitigate risk. The FILO SWD #1 well satisfies all eight.

  15. Summary • FILO SWD #1 will be one of the most protective injection wells in Oklahoma. • Arbuckle Formation has inherent safety as a disposal zone. • Trucks will discharge only to secure pipe connectors, not dump to open pits. • Well equipped with full-time fluid conductivity and density sensors with automatic shut-off valves to prevent dumping of illegal, hazardous waste. • Well is the first SWD well in Oklahoma with a dedicated seismic monitoring network.
