Sound Oil PLC. said Monday it will sidetrack the Nervesa appraisal well after the drill pipe became stuck at a depth of 3,566 feet. The well was drilling in the Upper Miocene conglomerate formation, a move that will increase the cost of the well by $1.5 million, Dow Jones Newswires reported.
After failing at several attempts to free the pipe, the operator cut the drill string at 2,904 feet, plugged the hole with cement and drilled a sidetrack.
The planned sidetrack is still expected to reach the planned bottom hole location within two weeks.
"The drilling team has reacted quickly and professionally to deal with the stuck pipe incident, having completed an assessment of its causes,” Chief Executive James Parsons said in a press release. “The company includes contingency in its budgets for such unforeseeable and uninsurable occurrences and remains committed to reaching the reservoir via the planned sidetrack.”
"The successful drilling of this flagship asset remains the first step in unlocking the significant value inherent in the Sound Oil portfolio," Parsons added.
