MUBARRAZ FIELD

Commercial production in Mubarraz Field
commenced in 1973. The Field consists of the Central
Facilities Platform (CFP), located in the center of
Mubarraz Field, three production platforms, seven
well platforms, and twelve tripod well platforms.
Fluid from the production wells is treated on the
production platforms for the first stage separation
and then transported to CFP through submarine
pipelines, where the oil and gas is gathered and
transported to Mubarraz Island via pipelines for final
processing. The CFP has a living quarters platform,
control room platform and a production platform,
which are connected by bridge.

AR AND GA FIELDS

Commercial production in the AR and GA Fields
commenced in 1989 and 1995, respectively. The
AR Site Terminal (ARST) is in the center of the AR
Field and is equipped with oil processing, sweet gas
injection and sour gas injection facilities. A causeway
provides onshore access from Mubarraz Island to
the ARST. Well-head streams from the AR and GA
Fields are gathered through the pipeline network at
the ARST, where both oil and gas are then separated
using multi-staged separators. The separated oil is
then transported to Mubarraz Island and the gas is
sent to sweet and sour gas injection facilities where
it is used in reservoirs to enhance oil recovery.

RIG OPERATIONS

We use jack-up type offshore rigs that are designed
to operate in the shallow waters. The rig possesses
a barge-shaped hull with three truss legs and is
also equipped with a derrick and other devices for
drilling and work-over operations. The jack-up rig is
towed to a location with its legs positioned upwards.
Once at the site, the legs are firmly positioned on
the seabed for work-over or drilling operations.
