Petronas To Implement EOR Technology On 14 Maturing Oilfields

National oil company, Petronas, is looking at implementing Enhance Oil Recovery (EOR) technology to enhance the production on 14 of its maturing oil fields in the future.

Its Vice President for Petroleum Management Unit (PMU) Ramlan Malek said the maturing oil fields were identified for possible EOR technology based on the screening study conducted by Petronas.

"Yes, certainly we are looking into other fields as well and based on our screening study, we have identified 14 oilfields where we can implement EOR in the future.

"Tapis is the first, the other fields we are going to implement it progressively," he told a media conference today.

He said this after attending the EOR Technology: Tapis-R Topsides Onshore Fabrication Celebration at the Malaysia Marine and Heavy Engineering (MMHE) Yard in Pasir Gudang here.

Also present were Petronas President and Group Chief Executive Officer Tan Sri Shamsul Azhar Abbas, President of ExxonMobil Exploration and Production Malaysia Inc. J. Hunter Ferris and Petronas Executive Vice President Exploration and Production Wee Yiaw Hin.

According to Ramlan, five of the maturing oil fields that would be enhanced with EOR technology are located offshore Sarawak and four offshore Sabah.

The rest of the oilfields are located in Peninsular Malaysia.

The 14 oilfields include Baram in Sarawak, St Joseph in Sabah and Tapis as well as the Dulang oilfields in Peninsular Malaysia.

Meanwhile, in an earlier briefing, Petronas head of EOR Programme Dr Nasir Darman said the date for final installation of Tapis-R topsides was expected in the first quarter of next year.

With the EOR technology, the current production on Tapis oilfield, which stands at between 4,000 and 6,000 barrels per day (bpd), could be enhanced to reach between 25,000 and 35,000 bpd in 2016-2017.

"With EOR technology, we can extend the lifespan of the maturing Tapis oilfield to 30 to 40 years more," he said, adding without EOR, the present production rate of Tapis would dwindle to only 3,000 bpd.

Nasir said with the introduction of EOR technology, Petronas could potentially recover between 750 million and one billion barrels of oil from those maturing oilfields scattered all over Malaysian waters.

Earlier in his speech, Nasir said Tapis is one of the largest offshore EOR projects of its kind in Southeast Asia and Malaysia's first large-scale full field offshore implementation of water alternating gas injection.

The Tapis EOR project is one of the 19 entry point projects and operated by Exxonmobil Exploration and Production Malaysia under the 2008 production sharing contract with Petronas Carigali and Petronas.

The total development cost of the project is estimated to be RM10 billion. The Tapis oilfield is located about 200km offshore Terengganu.
