Comments

The Kepiting Field was first developed in 1985 with two (2) subsea systems. This effort was followed up with three (3) wells on Ikan Pari and one (1) well on SA-1 in 1989. The Ikan Pari and SA-1 trees were designed for subsea flowline layaway installation. In 1994, the three (3) systems from the Ikan Pari Field were recovered, refurbished and deployed on the Belida Field.
