19 Performance Polymer Flood First Polymer Injection in October 2010 Hydrating polymer concentrations: ppm Polymer trace in produced water: >900 ppm within pilot 19

20 SEAL Polymer Pilot Pilot consists of 3 injectors and 4 producers. Approval No B to downspace on the East side of the pilot. 70 meter spacing Production response has been observed since Q

21 Performance Production/Injection Profile Increased production >70 m3/day Production spike in 2010 due to 2 infill wells Maintained plateau for 1.5 years Observed that: Reduced injection rates = Reduced production rates 21

22 Performance Polymer Flood Response noticed in Q3, 2011 Increased Water cuts on all producers (<50%) Maintaining reservoir voidage at approximately 100% Volume of injected polymer to date 142,679 E3m3 Expected incremental recovery factor after polymer flood 8.8% Produced solution gas from the pilot & expansion is captured and tied in to 4-33 battery. No response has been observed in the expansion areas. 22

23 Performance Key Learning s 70m spacing more effective compared to 140m Observed reduced GOR s within the pilot area Wells need to be lined throughout the horizontal section Injectivity is a non-issue with wells on vacuum at the start of injection Higher injection pressures yield better production Water production increases before oil response Source water quality and quantity is crucial for the success of the project Higher TDS (specifically Fe & Mg) results in higher polymer concentrations to achieve required viscosity 23

24 Subsurface Background Geology Drilling & Completions Flood Performance Injection Pressures Future Plans 24

25 Injection Pressures Polymer Injection Approval Pressure (Approval # 11320) MAWHIP 3,780 kpa MABHIP 9,800 kpa Monitoring Injection Pressure At least 1 well on each pad within the polymer expansion is equipped with down hole pressure and temperature monitoring. Surface pressure recorded daily and monitored to ensure MAWHIP is not exceeded. 25

26 Injection Pressure W1330 W1050 W910 W770 Decline in pressure *April, 2012 was due to reducing injection rates to a 1:1 ratio with production volumes Injection pressures are monitored by means of pressure transducers throughout the horizontal sections of the above mentioned wells 26

27 Subsurface Background Geology Drilling & Completions Flood Performance Injection Pressures Future Plans 27

28 Future - Expansion Plans Murphy has commissioned 2 of the 3 area s of the commercial expansion. Area 3 injection is planned for December 2013 Murphy is in the process of drafting up an application for further polymer injection within Central Seal. 28

29 Future Plans- Expansion Located in Central Seal just North of existing pilot and expansion. Similar reservoir characteristics and viscosities 29

50 UWI: 1F1/ W5/0 Water Usage - Paddy Formation Murphy currently has term license with Alberta Environment for the diversion of up to 164,260 m 3 of Paddy water for injection with an expiry date of UWI: 1F1/ W5/0 *not on production No TDL necessary with TDS testing >4000 ppm 50

51 Water Usage - Notikewan Formation UWI: 1F1/ W5 *not on production UWI: 1F1/ W5 *not on production TDL s are not needed for Notikewan wells with TDS >4000 ppm 51

52 Water Usage Planning and Operation Murphy is currently developing a water management program for the entire Seal field Produced water recycling is challenging with the presence of hydrated polymer. An economic solution is needed to handle produced emulsion at lower treating temperatures In compliance with Alberta Environment regarding weekly reporting and all other terms of the License 52

53 Water Usage Injected Volumes Pilot & Area 1 Area 2 53

54 Water Usage Produced Volumes Produced volumes are reported from test tanks located at the well site (tested weekly) From the start of the polymer flood there has been a recorded 7,623 m 3 of produced water Water volumes are calculated through BS&W tests conducted simultaneously with the well test Proration factors for production volumes are calculated using standard accounting procedures which are outlined section 3 of Directive 17 and section of Directive 7. Proration factors are also included as part of Directive 76 (Theme 14) for which Murphy reviews and signs off on as part of our controls environment. Produced water is currently being injected into disposal wells 102/ W5/0, 100/ W5/0 and 100/ W5/0 Proration Factors for

58 Regulatory - Scheme Approval Murphy is not aware of any outstanding compliance issues regarding the current approvals Murphy is in compliance with other regulatory bodies (SRD, AENV, DFO) 58

59 Surface Facilities Non-Saline Water Use and Conservation Regulatory Future Plans 59

60 Future Expansion 2 Murphy is currently looking into the required infrastructure needed to expand the polymer flood within Central Seal. 60

61 Conclusion Murphy is committed to maximizing the value of the resource for both itself and the province of Alberta through it s royalty interest Results over the last year have continued to show polymer flooding in heavy oil as successful, which supports the future expansion of the polymer flood Compliance with all ERCB regulations continues to be a top priority 61
