Major facility will ensure continuous supply of gas to downstream industries in the Sultanate of Oman through total inlet gas flow of 49m standard cubic metres per day
The Omani subsidiary of Técnicas Reunida, the Spanish international general contractor, announced on Saturday that it had completed work on Petroleum Development Oman’s Saih Rawl Depletion Compression Project.
The facility was inaugurated by HH Sayyid Mansour bin Majid al Said, advisor to the Minister of Heritage and Culture, and is designed to handle a total inlet gas flow of 49m m3 per day, comprising of four compressor packages. The project was completed with the help of Técnicas Reunida Oman’s construction partner, Bahwan Engineering.
“With the inauguration of the Saih Rawl Depletion Compression facilities, TR Oman, as prime engineering, procurement and construction contractor for the project, and their construction partner, BEC, have achieved a major milestone which demonstrates their strength in successfully completing large-scale upstream oil and gas projects,” the contractor said in a statement.
Once the gas is produced from Saih Rawl, the reservoir pressure of Saih Rawl wells will decline over the remaining lifetime of the field. In order to continue processing wet gas from Saih Rawl wells and maintain its current gas export capacity, the inlet pressure of the gas conditioning trains in the Saih Rawl CPP must be maintained constant at 96 Bar(a), TR Oman explained.
“To achieve this, two stages of depletion compressors are anticipated – Phase 1 when reservoir pressure drops till 35 Bar(a) pressure, which is now implemented, and Phase II when the reservoir will drop till 15 Bar(a) pressure, currently in the tendering stage, to guarantee the inlet pressure of 96 Bar(a) at the processing plant,” it continued.
In addition to the gas compression facilities, a new power station (Saih Rawl 2 – Power Station) has been installed to supply power to the compressors. The power station comprises of a single gas turbine generator unit of 120-160MW, which uses natural gas as a single fuel, a report in the Oman Daily Observer said.
The commissioning of the SRDC project has ensured that there is a continuous gas supply to downstream industries such as Oman LNG, Sur Industrial Estate and PDO for power generation, thus maintaining Oman’s industrial growth momentum, the report added.
