IN THE NEWS / Lost Hills Workers Set Up Shop At Site Of Well Blowout Filed: December 17, 1998 By BOB CHRISTIE Californian staff writer LOST HILLS - A small industrial site has sprung up here where a wildcat gas well blew out and caught fire more than three weeks ago. Hundreds of workers are toiling to run a small oil/water/natural gas separator operation, clean up oil-doused areas, prepare for further well control operations and ready a new drilling site. The well, which blew out Nov. 23 and burned for two weeks, still is spouting a continuous stream of water, oil and condensed natural gas liquids and a large amount of natural gas. That gas is being burned off, creating a huge flare and a plume of steam, because the well's operators are using the fire to burn off about half of the water flowing from the well. The amount of gas being produced by the wildcat well is a matter of intense interest. Observations by three different sources that have knowledge of the well's operations put the amount of gas being flared as high as 40 million cubic feet per day, an amount equal to more than 7,000 barrels of oil. However, the president of the company that is operating the site, Aidan Walsh of Elk Point Resources Inc. of Calgary, cautioned that he does not have consistent and accurate measurements of the amount of gas coming from the well and any estimates could be wildly inaccurate. "The volume estimates of hydrocarbon and water being produced at this time are not reliable due to very high temperatures and fluctuating operating conditions," Walsh said. "It's a unique situation - because of the very high temperatures, a lot of the hydrocarbon that would normally be liquid is being flashed off and flared and consumed. They are very high temperatures; that's why the volume estimates of hydrocarbons and water are not reliable." Regardless of the lack of accurate production numbers, the well appears to be putting out a great deal of gas - a flaring device burns consistently with a flame more than 50 feet long and roiling up to 75 feet in the air. A new valve placed on the well head last week by a team from Boots & Coots International Well Control of Houston is sending the water and hydrocarbons flowing from the well into two 7-inch diverter pipes, which lead to a mini-refinery designed to separate oil, water and natural gas. About 9,000 barrels of water are being trucked away to disposal wells each day; the rest is mixed in the gas flare and vaporized. A new Nabors Drilling USA well drilling rig has been erected about 1,500 yards away from the site of the original well, and was expected to begin the minimum six-week job of drilling a relief well late Thursday. That well will be sunk to depths between 13,500 and 14,000 feet before being sidetracked to intercept the blown well. If the well hasn't been controlled by above-ground efforts by the time the relief well reaches that depth, it will likely be sealed by pumping cement into the bore from the relief well. A snubbing unit is being brought in to try to control the well from above ground. According to Boots & Coots lead firefighter James Tuppen, the snubbing unit is designed to be able to enter a well even in the presence of very high pressures, through an elaborate series of blowout preventer valves. Many operations are possible if the well can be entered with the snubbing unit, including retrieving part of the drilling string lost when the well blew and testing the well's casing for failures. At the well site Thursday, teams of hazardous materials specialists wearing protective garments steam cleaned the concrete banks of the California Aqueduct, removing a residue of light oil and natural gas liquids that rained down on the area for the four days the uncapped well was not ablaze. Dozens of acres of nearby farmland also has been coated in a thin film of light brown liquid. The breeze carries the light smell of oil. Walsh said local specialists are working to clean the area and assess the extent of operations necessary. The oil tainting the soil of nearby farmland could be consumed by naturally occurring bacteria, he added. Officials with the state Department of Water Resources, which operates the aqueduct, said there is no contamination of water supplies and any oil that has gotten into the water has been skimmed off. Booms and absorbent materials are slung in the waterway to collect any residue from the steam cleaning operations. Testing has been done regularly and shows no discernible oil. "We've had oil spills before; we know how to deal with it," said Dee Bankston, operations chief with the local field division of the Water Resources Department. "We're trained in it. We do all the notifications and handle it. "If there was any danger at all we would be shutting the system down and taking care of it," he added.
