The well intersected some 50m of a predominantly coaly Kapuni sequence, with only relatively low levels of gas, before the drill string became stuck in the hole at 4845m. All attempts to free the drill pipe failed and finally the string was severed at 4304m, leaving a significant section of pipe in the hole.
The Joint Venture decided that hydrocarbons indications in the Kapuni Formation were not sufficiently encouraging to warrant testing or sidetracking.
