The 04-2-HT-01X well, which is the first exploration well of a two-well program for 1995, commenced drilling on July 12, 1995. The well was plugged and abandoned on September 21, 1995. The well reached a total depth of 4,548 meters (14,922 feet). Although gas shows were encountered over a large interval while drilling, no flow tests were conducted due to poor reservoir quality.
