The major petroleum services provider said the RHIP facility will include sour gas processing facilities and associated gathering and injection systems and export pipelines.

"It will handle the production of oil and gas from the Harweel oil reservoirs via miscible gas injection and the production of gas with condensate from the Rabab reservoir through partial recycling of sour gas," Petrofac said.

"The facility will deliver peak export of 4.9 million standard cubic metres per day of sweet gas and 9700 cubic metres per day of condensate in addition to approximately 16 million standard cubic metres per day of high pressure sour injection."

Awarded by Petroleum Development Oman, the contract will last 4.5 years.

"We have a strong track record in Oman with PDO as well as direct engineering, procurement and construction experience on the previous Harweel development," Petrofac engineering and consulting services managing director Craig Muir said.

"This award also underpins Petrofac's strategy to enhance service capability in the Middle East, providing added value to our regional customers as well as our onshore and offshore EPC business."
