Ceiba Field
The Ceiba Field
was discovered in October 1999 and first production was achieved
in November 2000, less than 14 months from discovery. Initial production
during 2001 was from 5 wells into the Sendje Berge FPSO (Floating
Production, Storage, and Offloading vessel). In January 2002, this
vessel was replaced by the Sendje Ceiba which has a total liquids processing
capacity of 160,000 bpd and facilities to inject up to 135,000 bwpd
into the Ceiba reservoir to maintain field pressure and optimise
oil recovery. Field development will then comprise 10 producing
wells and 4 water injector wells. Oil production is expected to
average 36,000 bpd in 2009. |

The Zafiro Field Complex
The Zafiro Field
complex produces around 140,000 bopd and 120 mmcfd of gas via the
Zafiro Producer, the Jade Platform, and the Serpentina FPSO facilities. Zafiro was discovered
in 1995 and was brought on stream within eighteen months of discovery.
Facilities have been expanded each year since production commenced.
In 2000, the Zafiro Producer FPSO was converted to an FPU (Floating
Production Unit) with crude oil being stored in the MT Magnolia
FSO (Floating Storage and Offloading vessel), which has a storage
capacity of 1.8 million bbls. Gas is separated from the oil on board
the FPU and the oil is sent to the FSO where it is stored until
it can be exported to tankers via a Single Point Mooring (SPM) system.
In December 1999 a 60,000 bopd fixed platform facility (Jade) was
installed. By May 2001 production from Jade had reached capacity
at 50,000 bopd. Gas is separated from the crude on the platform
and the oil exported via pipeline to the Zafiro FPU. In 2002,
the Serpentina FPSO was added to the southern part of the field, leading to peak rates of over 300,000 bopd. |

Alba Field
Alba is a gas condensate field with total
reserves expected to exceed 5 Tcf. The Alba Field was discovered in
1983 but was not placed on production until 1991 when it was developed
solely for its condensate production by Walter International Inc..
By 1995, when Nomeco acquired Walter, Alba was producing at a rate
of around 65mmcfd to yield over 6000 bpd of condensate with all
the gas being flared. During 2000 CMS (who had acquired Nomeco)
drilled the Alba -6, -7 and -8 development wells and by mid 2001
Alba was producing over 195 mmcfd, to generate 14,000 bcpd and 2,000
bbls LPG/day. The processed gas supplies a new methanol plant which
is designed to produce at a rate of 19,000 bpd from with minimal
gas flaring. In January 2002, Marathon Oil acquired the CMS interests
in Equatorial Guinea.
Following the commissioning of the LNG plant in 2007, the gas offtake from the field has risen to 900 mmcfd. This gas provides feedgas to the LNG and Methanol plants, is used in local power generation, and yields some 70,000 bpd of LPG and Condensate.

Okume Complex
The Okume Complex was discovered in 2001 and celebrated first production in December 2006, less than 3 years after approval of the Plan of Development. The Okume Complex is comprised of the Okume, Oveng, Ebano and Elon fields which have been developed using a combination of two tension leg platforms and four fixed platforms. Production from the fields is gathered at a central processing facility (CPF) located at the shallow water Elon field. From there, a fifteen mile subsea pipeline connects the CPF to the Sendje Ceiba floating production, storage and offloading vessel (FPSO) for storage and offloading of crude production. By the end of 2009, there are 20 oil production wells and 9 injection wells water on stream. The average production in 2009 is expected to be some 72,000 bopd. The Okume Complex is anticipated to reach a peak production rate of 80,000 bopd in early 2011. |
