Maximising oil recovery from maturing oil fields

August 3, 2013

Dateline 2013-07-05, Sin Chew:

Malaysia is set to enhance its crude oil recovery from its maturing oil fields through the Enhanced Oil Recovery (EOR) technology using its own expertise in petroleum engineering.

Works are already underway to implement EOR at the Tapis oil field located about 200 kilometres off Terengganu that produces extra-light and low-sulphur crude oil.

Tapis is one of seven mature offshore fields that ExxonMobil Exploration and Production Malaysia Inc. (EMEPMI) and PETRONAS Carigali Sdn Bhd (PCSB) have agreed to develop as part of a 25-year production-sharing contract that was finalized in 2009.

The EOR is a major engineering milestone for the country as local companies like SapuraKencana Petroleum Bhd and Malaysia Marine and Heavy Engineering Holdings Bhd (MMHE) are involved in fabricating the jacket and deck respectively.

Petronas And Shell Sign Oil Recovery Deal

Someone asked me about definitions, IOR, EOR, secondary oil recovery, tertiary etc. I say, look at Schlumberger Oilfield Glossary.

Malaysia plans to launch the world’s biggest offshore enhanced oil recovery (EOR) project that will have a positive impact on the country’s oil reserves, Prime Minister Najib Razak said Monday.

The RM38 billion (S$15.5 billion) project is a joint-venture between national oil company Petronas and Shell Malaysia that will last 30 years.

“I am confident that this landmark undertaking will prove another significant milestone, not only for Petronas but for Malaysia’s development as well,” Mr Najib said at the signing of two new production-sharing contracts between Petronas and Shell.

The EOR technology, which will be employed in the Baram Delta and North Sabah fields, will help to boost the recovery efficiency of the oil fields to about 50 per cent and extend the fields’ life to beyond 2040.

If the project is successful, it could lead to the world’s first offshore Alkaline Surfactant Polymer EOR project using horizontal wells. It will also provide additional supplies for the country’s power and industrial needs, and promote organic growth in the oil, gas and energy sector, reported The New Straits Times.


From Bernama – MMHE Secures RM1.4 Billion Contract From EMEPMI

Malaysia Marine and Heavy Engineering Holdings Bhd (MMHE) has secured the RM1.4 billion Tapis Enhanced Oil Recovery (EOR) project from ExxonMobil Exploration and Production Malaysia Inc (EMEPMI).

The contract from the subsidiary of Exxon Mobil Corporation is for the construction and installation of the main structure for the Tapis R topside, which is the main structure of the Tapis EOR project.

EMEPMI chairman and president, Hugh W Thompson said the contract was part of the company’s long-term commitment to work closely with PETRONAS and their co-venture partner PETRONAS Carigali to develop Malaysia’s full energy potential.”

Taken from AOG – PETRONAS and EOR

March 6, 2009

Taking the article from the Asian Oil & Gas magazine,

Malaysia has set itself an ambitious target to add an additional 520 million barrels of oil to its reserve by 2010 by applying EOR technologies to its offshore oilfields.

According to Dr. Nasir Hj. Darman of …

Hopefully, the spill off will allow us small specialist engineering companies to soldier through these trying times. Even though most of the work is downhole, the PSCs must need to design additional topsides facilities (im thinking water injection here) to pursue their EOR of choice.

Enhanced Oil Recovery – the Malaysian Experience

May 30, 2008

I’ve found the Schlumberger Oilfield Glossary to be a useful source of info, helping me figure out where Enhanced Oil Recovery is used in Malaysia.

  • Water Alternating Gas (WAG) is a EOR method which has been looked at. I believe PRSS was looking at it when they still existed.
  • Chemical EOR is being tested as a pilot project at PCSB’s Angsi asset. Akaline surfactant is injected into the reservoir to reduce water flood residual oil saturation.  
  • I believe EMEPMI is looking at WAG, though I don’t know whether it’s a table top exercise, or they have moved to field trials.

At USD 129 / barrel, EOR is definitely more profitable.

If you know more, please write in, esp. as to what is happening in East Malaysia.

ExxonMobil – extension of PSCs

April 3, 2008

I earlier reported that TCOT / OSC were being handed over to PCSB. Now I can note that ExxonMobil Exploration and Production Malaysia Inc’s (EMEPMI) Production Sharing Contracts (PSC) were extended.

At 3:00 p.m. on Wednesday, March 26, EMEPMI signed with PETRONAS and PETRONAS Carigali the Main Principles Agreement that will lead to the execution of a new Production Sharing Contract (PSC).

In summary, the new PSC will enable EMEPMI to continue production of the existing reserves in the seven fields currently under the 1995 PSC until 2033.  It will also be pursuing additional oil development and will have the opportunity to pursue Enhanced Oil Recovery (EOR) activities. 

As part of the arrangement, EMEPMI will retain operatorship of all the existing offshore fields, and will extend this to 2033.  Operatorship of the onshore assets, and in particular the Terengganu Crude Oil Terminal (TCOT), will be transferred earlier than initially planned, and will be accelerated from 2012 to no later than June 2009 along with the gas and condensate facilities (i.e. OSC).  This transfer is strategic to PETRONAS due to national interest considerations.

Other aspects of EMEPM’s current onshore operations at Kemaman Supply Base will
remain as is.
