Firms submit bids for PDO gas project


Petroleum Development Oman (PDO) has received bids from local and international engineering construction firms for the second phase of its Saih Rawl Depletion Compression (SRDC) project in central Oman

Firms have already submitted financial and technical bids for phase two of the project, which will involve the construction of four parallel compression trains with a total capacity of 30 million standard cubic metres of gas per day (MMSCMD), said a report in the Oman Observer.

The next phase of construction has been scheduled for completion in the first quarter of 2015 and will enable the reduction of the Central Processing Plant (CPP) inlet pressure from 35 to 13 bar. In addition, the selected contractor will also install 76MW of gas compression capacity, as well as carry out some modifications to the condensate handling system at the CPP.

The issuing of tenders for the second phase comes soon after the inauguration last month of the first phase of the SRDC project, which was completed and commissioned last year. The new plant now has a capacity to handle 48 million standard cubic metres of gas per day.

Saih Rawl is the largest gas field in Oman, but after 20 years of continuous production the field was maturing and the reservoir pressure had started to decline. This is why PDO went ahead with its depletion compression project and has managed to boost inlet pressure from 36 bar to 96 bar.

Gas and condensates from the Saih Rawl field are collected and processed at the CPP where the depletion compression is located. The treated gas is then sent to customers such as Oman Liquefied Natural Gas (OLNG), Qalhat LNG and South Oman Gas Line via a pipeline known as the Interconnector.
