On the afternoon of September 9, 1999, while coiled tubing was being snubbed into Well A-2, it encountered an unknown obstruction that caused it to stop abruptly. Upon coming to a stop or shortly thereafter,the coiled tubing buckled and parted between the stripper assembly and the injector head resulting in the release of hydrocarbons to the atmosphere.
