8 Japan GTL studies Screening studies conducted between JOGMEC & VPI, potential fields identified. Agreement for Phase 2 of study was signed on 4/2011. Japan GTL is potential solution for : High CO2 gas fields development Intergrationwith CO2 EOR Project JOGMEC Techno Forum Tokyo, May 7-8,

9 Potential fields for Japan GTL Potential for developments - Block Block 117, 118, 119 (high CO2) - Block 04-3, Block 46-2 Japan GTL Demonstration Plant in Niigata

CO2 EOR studies 2008-2010 Rang Dong CO2 EOR MOU between PVN and JX-NOEX was signed on 9 th May, 2008 Phase 1

11 CO2 EOR studies Rang Dong CO2 EOR MOU between PVN and JX-NOEX was signed on 9 th May, 2008 Phase 1 Study (Source: PVN, 2008) CO2 Huff&Puff Pilot Test Hydrocarbon Gas EOR Cuu Long Basin fields CO2 Potential Study 11

CO2 EOR Pilot Test (Huff'n'Puff) in 2011 17-days

12 CO2 EOR Pilot Test (Huff'n'Puff) in days Test (May-June 2011) 111 tons of CO2 injected and flowed back (2.1 MMscf) Pumped CO2 from boat 7 hours CO2 Injection and 4-days flow back (Source: JOGMEC, 2011) 12

13 CO2 EOR Pilot Test (Huff'n'Puff) in 2011 (cont.) EOR effect is confirmed: Oil rate increased (up to 1500bpd) Water cut dropped Oil saturation changed CO2 utilization factor 9.8 Mscf/bbl (Source: JOGMEC, 2011) 13

01. CO2 Management Conventional Membrane System Two skids; Footprint = 257m 2 /ea Weight (w/elements) = 302 tons (Source: Talisman Energy, 2012) Difficulties:

15 01. CO2 Management Conventional Membrane System Two skids; Footprint = 257m 2 /ea Weight (w/elements) = 302 tons (Source: Talisman Energy, 2012) Difficulties: High CAPEX High frequency of maintenance jobs (every 6 months) Reduce production when doing maintenance Not commercial to develop very high CO2 reservoirs (70-80%) 15

16 01. CO2 Management (cont.) Current development in PM-3 CAA field shown many difficulties in CO2 management (removal): High CAPEX for CO2 removal facilities (membrane) Requires frequent maintenance (reduce prod. rate) Environment unfriendly (vent CO2 to the air) Middle Vietnam has many TCFs gas reservoirs with high CO2 content! How to develop these reservoir efficiently?! GTL/EOR/CSS? 16

17 02. EOR Big fields are mature & production declining <= the need of applying EOR to maintain production rate. EOR methods: Thermal: not applicable in Vietnam Chemical: limited studies, poor laboratory facilities. Gas injection: We have BIG CO2 sources (gas fields) + BIG potential to apply CO2 EOR (pilot test confirmed!) How to well match these two parts in one mega project?! 17

18 03. Mercury Content Treatment Difficulties: High CAPEX High frequency of maintenance jobs Reduce production when doing maintenance No technology available to remove Hg in Oil Service Companies: (Source: Talisman Energy, 2012) 18

19 03. Mercury Content Treatment (cont.) Difficulties in handling Hg content: High CAPEX for removal facilities Requires frequent maintenance (reduce prod. rate) No technology available to remove Hg in Oil Transport, Storage & Disposal of Mercury Big project (KL-AQ-CV) in development phase, is going to face with this problem! How to resolve this issue efficiently?! 19

20 04. Marginal Fields Development Traditional offshore field development schematic: WHPs + FPSO + Pipeline + Conventional wells - Heavy (topside around 2000 tons) - High CAPEX - Mostly not reusable - Not commercial for marginal fields (ie. <100 mmstbo) We have many marginal offshore oil and gas fields, with: - Strictly metocean conditions (storm, high wave) - Scatteringly distributed How to develop these field commercially?! 20

$Need more studies and new Initiatives to successful model fractured$

21 05. FracturedBasementReservoir Management The development of Halo model Many other technologies applied (Artificial Neural Network, DFN, dual porosity, ) but yet not to achieve good result. Need more studies and new Initiatives to successful model fractured basement reservoirs!

22 Summary The co-operation between PVN & JOGMEC in the past has demonstrated beneficial for both sides. Japan technologies have been successfully applied in Vietnam. In alignment with New Initiative of JOGMEC, we (PVN) would like to introduce our current focusing topics and our expectation to your technology in solving them, including: High CO2 reservoir development, application of GTL, CSS EOR utilizing CO2 Mercury content treatment Marginal fields development Fractured basement reservoir management
