The Lengowangi field, located onshore East Java, Indonesia was discovered in 2006. The main challenges in this area have been the over-pressured Lower Ngrayong and Tuban formations. The first well, L-1, was successfully drilled in 2006 and currently produces up to 10 MMCFD. The second well, L-2, was drilled up-dip in 2008, but could not reach the target because of well control issues related to high pore pressure. Well was TD'd about 2800 ft MD shorter than planned depth. * JOB Pertamina
