OML 55

OML 55 is about 40km west of Bonney Terminal and located in the mangrove swamp to shallow water offshore in the south-eastern part of the Niger Delta and covers an area of 852km² approximately. It is situated in the coastal depobelt of the Niger Delta of Nigeria.

It was previously operated by NNPC/Chevron Joint Venture (JV) but handed over to Belemaoil Producing Limited in joint partnership with NNPC in February 2015. The block extends 65 kilometres from East to West. Contagious blocks to OML 55 include OMLs 11, 18, 19, 23, 24, 25, 29, 52, 72, and 74. The current producing Fields are Robertkiri, Idama, Jokka, Inda and Belema North. The Belema North is unitized with OML 25 south-west of the concession. The current production figures range from 9,000 – 14,000 bopd and more than 70 MMscfd recoverable volume of gas.


OML 55 has an estimated hydrocarbon reserve of circa 350 mmboe. In order to grow output, Belemaoil has embarked on an aggressive exploration and development activities. A seismic contract has been signed with the IDSL/BGP JV and mobilized a seismic crew with a 3D configuration to acquire data over the entire acreage from the swamp to the shallow water south of the block deploying state-of-the-art technologies in seismic surveys and field development optimization methods to evaluate deeper prospectivity, improved fault-shadow imaging, improved imaging of the cretaceous and other opportunities. The massive seismic campaign is planned to deliver quality seismic products within 3 years of continuous operation. The exploration strategy is focused on the optimization of previous parameters with a view to improving on previous seismic data sets acquired from 1964 to 1995 by workers that deployed different seismic exploration configuration, parameters and equipment.   The current acquisition design with a high aspect ratio is aimed at using long offset parameters and wide azimuths with record length to 12 seconds for deeper penetration far beyond the data sets previously acquired in the Niger Delta. Apart from imaging deeper stratigraphic structures, the new set of seismic data would be used as monitor survey for reservoir surveillance, prospects maturation, produce better illumination of the fault-shadow images and to validate new leads for future opportunities with a view to increasing the hydro-carbon reserves and maximally utilize the existing ullage of current in-field infrastructure in Robertkiri, Idama and Inda production facilities.
