Dresser-Rand will supply advanced turbomachinery for the SBM Offshore (SBM) FPSO to be used offshore Equatorial Guinea on the Aseng field. The Aseng field is operated by US independent Noble Energy.
Dresser-Rand will supply gas compression and power generation packages including four DATUM® centrifugal compression trains driven by electric motors and three DR-61G (LM2500) gas turbine generator sets. The compressor trains will be manufactured in Olean, NY, and the gas turbines will be engineered by Dresser-Rand Kongsberg and packaged at Samsung Techwin’s facilities in Changwon, South Korea. As previously reported, Dresser-Rand booked the order in October 2009.
“We are very pleased that SBM has selected Dresser-Rand to supply the critical rotating equipment for this important project. Our team worked closely with SBM on selecting the best technology to meet application requirements and offer a single-source solution for compression and power generation,” said Jesus Pacheco, Dresser-Rand’s executive vice president, New Equipment Worldwide.
SBM Offshore signed a contract with Noble Energy for the provision, lease and operation of the FPSO, which will operate in 3,281 feet of water. The FPSO will have capacity to handle 120,000 barrels of liquid per day, including processing of 80,000 bpd of oil, injection of up to 150,000 bpd of water, as well as handling 170 Mmcf/d of gas. The unit will have storage capacity for 1.6 million bpd of oil including up to 500,000 bpd of condensate.
The Aseng field, formerly known as the Benita, was originally discovered in 2007 as a gas-condensate field on Block I. Subsequently, two appraisal wells were drilled in the structure with the first well identifying the oil resources and the second well determining reservoir limits. A development plan was submitted to the country’s Ministry of Mines, Industry and Energy in late 2008 and the plan has now been sanctioned.
Noble serves as the technical operator of the development which includes five subsea wells flowing to the FPSO. The natural gas and water produced will be re-injected back into the reservoir to maintain pressure and maximize oil recoveries. Total cost of development, excluding the cost of the FPSO is estimated at $1.3 billion. The majority of this capital is to be invested in 2010 and 2011. First production from the field is estimated to start at 50,000 bpd of oil in 2012.
