Depending on its drilling success, Apache will have the option to continue drilling additional wells pursuant to the Agreement. In addition, Apache will commit to shooting a minimum of 45 square miles of 3D seismic over the lands and will re-enter, test and recomplete a further 10 existing wells to earn Penn West's interests, also subject to a NCGORR with no deductions.
