Block SC14B contains the Matinloc, Libro and Pandan fields. The three fields were developed together, with Libro and Pandan producing minor quantities of oil from a single well on each field. Libro and Pandan were shut-in, in 1988 and 1991 respectively. The Matinloc field was brought onstream in 1982. The field was shut-in in 1991 due to declining production. In July 1995, it was reactivated by working over two wells.
