Located on a sand spit east of Mullet Island.
The F2 field is roughly 120 m x 400 m and irregular in shape. It is subdivided into the F2 north complex (F2NC), a small outlier to the northwest and the F2 base complex (F2BC). The fluids at F2 are more viscous than at F1 which has allowed the development of mud pots and mud volcanoes/gryphons to 1-2 m high.
