2012 AAPL Annual Meeting Sponsors Platinum Gold Silver Bronze San Francisco Seminar Golf A wholly owned subsidiary of ExxonMobil
Blowout Hazards • Radiant Heat • Noise!!!! (120dB) • No Fire • Explosion • Methane Exposure • Explosion • Oxygen Deficiency • Explosion
Radiant Heat Consequences • A 50 MMscf/d Fire would: • Produce a 140’ Flame • Metal failure within 50 feet • Spontaneous ignite all wood/paper/houses within 50 ft • Burn people within 100 feet if unprotected after 1 min
Gas Hazardous Environment • Large Radius of hazardous environment from gas plume • Evacuation of All Residents within 1 to 3 miles is common • Aerial Evacuation of 2 to 3 miles w/ altitude of 4000 feet • Risk of ignition
1 Mile Radius of Gas Storage Well In Strip Center Parking Lot
When Unable to Control from Surface – options? • Wait for well to bridge • Drill a Relief Well • Mobilize Appropriate Rig • Directional & Ranging Work • Dynamic Kill • $$$$$$$ and time
Gas Storage Well • Frequently in urban environment • Cavern storage • 5 – 15 BCF • Cavern evacuated +/- 7 days • Intense thermal effects • Potential cavern collapse
Fire Pumps (4000+ GPM) & Monitors • Water Source ( 2 Million Gal/day) 6 Ac-ft • Heat Shielding • Athey Wagon & Venturi Tube • Capping Stack • Tools, hoses, pipe and connections • Heavy Equipment • D8 Dozer w/ Ripper, D8 Dozer w/ winch • 235 Cat Trackhoe • 150 ton Crawler Crane w/ 100’ boom • Rough Terrain front end loader/forklift
Typical American City FD Pumper has a 1000 GPM capacity Gas wells take 3000 to 6000 GPM for water curtain Water Storage (6 Ac-ft)1 Ac that is 6’ deep (210’ x 210’ x 6’)Or 2 MM gallons
Capping Stack on Athey Wagon Double Blind Rams
Abrasive Jet Cutter Requirements • Hydraulic Horsepower (2,000 hhp) • Pumping Iron • Sand Requirements (20/40 Ottawa preferred)
Well Just before Closing Blind Rams, Diverter Lines Open, Water flow into BOPs Stopped
Blind Rams Closed Well on Diversion
Antonov 225/124 IAH
Offshore Firefighting Considerations • In Some Areas, Marine Vessels With Substantial Firefighting Capabilities (10,000 to 20,000 gpm) are Limited.
MV Dino Chouest 18,000 gpm water cannons in use to protect platform from further damage if well ignites. Note huge amount of water coverage
