Sincerely, James T. Rodgers Manager- GKA Light Oil Greater Kuparuk Area Attachment 1 Kuparuk River Unit Kuparuk River Oil Pool 2007 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project Enhanced Recovery Miscible water -alternating -gas (MWAG) continues to serve as the main enhanced oil recovery process for the Kuparuk field. The total number of MWAG drill sites that service the Kuparuk reservoir is 32 with 288 available EOR patterns. Many of these patterns are now mature in that they have received the originally designated volume of miscible gas injection. These mature patterns generally no longer receive miscible injectant (MI) but are available for use as lean gas injection wells when plant upsets occur. The field continues to manufacture miscible injectant at two of its Central Processing Facilities (CPF's). MI manufacture occurs by blending together produced lean gas and natural gas liquids (NGLs). The NGLs originate from two sources: (1) the Kuparuk field itself (known as indigenous NGLs), and (2) those NGLs imported from the Prudhoe Bay Field Central Gas Facility. Importation from Prudhoe Bay is utilized to fill any shortfall between the total NGL requirement and the available indigenous NGL production. From a flood management perspective, all available lean gas after fuel use is blended with these two NGL streams to maximize the daily volume of MI generated in the field. During 2007, the MWAG project operated in full MI production mode for most of the 32 MWAG drillsites. Three mature MWAG drillsites (drillsites 2U, 2V and 2" were chosen to conduct lean gas chase tests. Lean gas, alternating with water has been injected at an average daily rate of 32 MMSCFD into these three drillsites, starting May 2007. The purpose of this lean gas injection is to collect data to evaluate post-MWAG options. Drillsites 21.1, 2V and 2W were under MWAG from January to April 2007. During the year 2007, Kuparuk imported an average of 26,867 barrels per day of Prudhoe NGLs. Import NGLs and indigenous NGLs blended with available lean gas generated an average of 259 MMSCFD of MI. The annual average MI injection rate into the Kuparuk Field was 196 MMSCFD. The remaining was utilized for Greater Kuparuk Area satellite fields, including 47 MMSCFD as injection and 14 MMSCFD as lift gas in Tarn and Meltwater. A small amount of MI (-2MMSCFD) is used as lift gas in drillsite 3S. The estimated incremental oil sales in calendar year 2007 from the ongoing Kuparuk MWAG project was 35.3 MBO/day, The priority for gas management at the Kuparuk field during 2007 was to balance solvent injection between the A -Sand and C -Sand. This maximizes total EOR and returned NGL rates while avoiding excessive gas production rates which would cause production impacts due to gas handling limitations. Total GKA annual average gas production rate in 2007 was 312 MMSCFD, compared to 307 MMSCFD during 2006. N MWAG Small Scale EOR (SSEOR and SSEORX) Drill Sites 1A, 1Y, and 2Z continued MWAG during 2007. The 2007 average MI injection rate was 2 MMSCFD. Large Scale EOR (LSEOR) The original LSEOR Drill Sites include: 1 F, 1 G, 1 Q, 1 R, 2A, 26, 2C, 21), 2F, 2G, 2H, 2K, 2M, 2T, 2U, 2V, 2W, 2X and 3F. The total MI injection rate into these drill sites averaged 87 MMSCFD in 2007. EOR Expansions Expansions to the original LSEOR occurred over multiple phases and now include Drill Sites 1 B, 1 C, 1 E, 1 L, 313, 3G, 3H, 30, 3Q and 3S. During 2007, the average MI injection rate into these expansion drill sites was 107 MMSCFD. IWAG During 2007 operations, the Kuparuk EOR project continued to maximize the volume of available MI by blending all available lean gas with Kuparuk-sourced and imported NGL. IWAG operations were conducted in Drillsites 2U, 2V and 2W beginning May 2007 to evaluate future post-MWAG options. 3 uJ N O X 0 O � W CN co I ' C: O O N O cM O O O 00 O 00 N N T /1 � � C C N C N f� V J � " � LLj O o o rn O Q o W c c cn � Of L- —m o W W W a) WLU t6 U) O O WW 0 0 O U o U) -i OW OW W 0- �P �l U yWN� WJ P m V- t W M M M m N N M M M N N O � N..�_ ._....._.._ M M N N co M ,=—P J r W 0 N N LL N N N N N 2 N ZS IL �.

Of the total MI production in 2007, 196 MMSCFD was injected into the Kuparuk Field. Within the main Kuparuk Field, the 196 MMSCFD was allocated as: 2 MMSCFD for the SSEOR and SSEORX drill sites, 87 MMSCFD to the LSEOR drill sites and 107 MMSCFD to the LSEOR expansion drill sites. LSEOR expansion drillsites include drillsites: 1 B, 1 C, 1 E, 1 L, 3B, 3G, 3H, 30, 3Q and 3S. Further drilling activity in the Kuparuk River Oil Pool potentially provides new opportunities to maximize field recovery while preventing physical waste. Drilling opportunities, along with their associated miscible gas EOR potential, are under constant evaluation as the field matures, geologic and reservoir performance information is assimilated and as technology improves. Although no new drill site -level expansions projects are currently sanctioned, the Kuparuk EOR project may be expanded to include any new wells. MWAG expansion to drillsite 1D has been evaluated during 2007 and the project is currently under approval process. MI injection in drillsite 1 D may start late 2008 or early 2009, with an expected MI injection rate of 34 MMSCFD. Mature patterns in other part of the field will be turned to water injection in order to supply sufficient volumes of MI to drillsite 1 D. 31 ConocoPhillips March 31, 2008 Mr. Dan Seamount, Commissioner Alaska Oil and Gas Conservation Commission 333 West 7th Ave. Suite #100 Anchorage, Alaska 99501-3539 Re: GKA 365 -Day Shut-in Well Report Dear Mr. Seamount, James T.

Rodgers Manager — GKA Light Oil Greater Kuparuk Area Ibcc: Central Files ATO -3 42 11 0 0 Attachment 1 Kuparuk River Unit Meltwater Oil Pool 2007 Annual Reservoir Surveillance Report Summary of EOR Project and Reservoir Management Summary Background In 2001, CPAI received approvals for formation of the Meltwater Oil Pool in the Kuparuk River Unit, an Area Injection Order for Meltwater, expansion of the Kuparuk River Unit, and formation of the Meltwater Participating Area. The Meltwater Pool Rules and Area Injection Order were approved on August 1, 2001. The Unit Expansion and Participating area were approved effective June 1, 2001. Injection of miscible injectant (MI) began in January 2002 and the MWAG (miscible water alternating gas) process was implemented during May 2003. The Meltwater MWAG process uses Kuparuk spec MI which is injected above the minimum miscibility pressure. For compositional analysis of the Kuparuk spec MI, refer to the Kuparuk section of the annual surveillance report. During the second quarter 2004, the 2P-427 was converted from production to injection service and injection began in the well during April 2005. The Meltwater field now has 19 total wells (12 producers and 7 injectors). Progress of EOR Project Development activities in 2007 followed the plans described in the Pool Rules, Area Injection Order, Unit Expansion, and Participating Area (PA) applications. Below is a listing of the key events related to the Meltwater Pool and PA in 2007: 1. Pigging of the 2P produced oil line was successfully completed in May 2007 and came in under budget and planned time. As a result of the success, the line was pigged a second time in November 2007. 2. Continued data acquisition program to collect valuable information on production and injection wells with limited data. The bulk of this program was completed in 2007, but work still remains for 2008. 3. Perforations were added to 2P-427 injection well, which had initially been completed as a fracture stimulated producer. After its conversion to injection in late -2004, the well was still only injecting through limited -entry perfs. In 2007 the entire reservoir interval was perforated, and offset producer 2P424A received positive support from this wellwork. 4. The four Meltwater wells on jet pump as a means of artificial lift had their pumps pulled and replaced in 2007. Tubing internal caliper and tubing/casing magnetic thickness logs were run, and there did not appear to be any signs of IA corrosion caused by the jet pump power fluid (produced water). Pressures and fluid rates are actively being monitored to detect such a failure if it were to occur. Below is a listing of the most important new findings derived from the 2007 Meltwater development efforts: 43 Ir --I J �I 11 t 1. Work is ongoing to rebuild the Meltwater subsurface model. Much of the work involves reanalyzing the current seismic data in order to better interpret the reservoir architecture and communication / support between the producers and injectors. Additionally, 3D seismic data that is being acquired in winter 2008 will be processed and interpreted to provide additional clarity into the reservoir architecture. 2. Outer annuli pressures in 2P-431, 2P-432, 2P-434, 2P-438, 2P-447, 2P -448A, and 2P- 451 remained at elevated levels in 2007. One additional well, 2P-406, was added to the list of "waivered wells" with elevated OA pressures (>900 psi). The calculated pressures at the C-80 interval are still below the measured/calculated leak off (refer to table of elevated OA pressures in Meltwater -Attachment 6). 3. When phase II injection wells were drilled in 2004, cumulative Injection/withdraw for the field was approximately 0.75. I/W rates for the subsequent years was approximately 1.5 to maintain voidage replacement. In late 2004 the cumulative I1W overtook 1.0 and has been steadily climbing since. At the start of 2007, INN ratio at Meltwater was greater than 2.0, prompting a change to reduce injection rates to get more in line with production and discontinue "over injection" into the reservoir. As a result, cumulative INV for the reservoir remained nearly constant at 1.25 throughout the year. Reservoir Management Summary Meltwater came on-line in November of 2001 and has cumulatively produced 12.2 MMBO, 926 MBW, and 29.3 BCF of gas by year-end 2007. Miscible gas injection began in 2002 with water injection beginning in 2003 (MWAG cycles). Cumulative injection through year-end 2007 at Meltwater has been 21.3 MMBW and 37.2 BCF of gas (of that 33.8 BCF of MI gas and 3.4 BCF of lean gas). Performance and surveillance data from the Meltwater producers indicates that they are receiving partial to limited support from offset injection wells. Further work will be done in 2008 to assess voidage replacement (on a pattern level, not fieldwide) and support issues in the field. The interpretation of the new seismic data should prove invaluable for imaging higher - pressured injection compartments and lower -pressured production compartments and help determine a path forward for connecting the two. 44 7 L Attachment 1 Kuparuk River Unit Tabasco Oil Pool 2007 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project Tabasco produced 1063 MBO of crude, 366 MMSCF of gas, and 5681 MBW during 2007. Water injection was 7707 MBW over the same period. Cumulative oil, gas, water production, and water injection through year end 2007 were 13.7 MMBO, 2.4 BCF, 46.9 MMBW, and 53.6 MMBWI, respectively. The cumulative injection/withdrawal ratio was 0.87 on a reservoir barrel basis through year end 2007. Injector 2T -217A remained shut-in waiting for post rig work to include a cement squeeze and surface facility work. Injector 2T -217A will be the second injector at Tabasco. 2T-203 had a new ESP installed in December 2007. Start up of this new ESP was not completed by year end 2007. Year end 2007 Tabasco well count (all at Kuparuk River Unit Drill Site 2T) was: Producers: 10 completed 8 on line Injectors: 2 completed 1 on line The water oil ratio (WOR) was 6.2 at the end of 2007 compared to 5.5 at the end of 2006. Water breakthrough has occurred at all eight producers. Production and injection logs, coupled with the structural positions and water breakthrough histories of the producers, suggest that the water production mechanism is dominated by gravity - induced slumping. 2T -217A will be brought on line in 2008 as the second Tabasco injector. 2T -217A is premised to provide additional flow streams to displace previously unswept oil and provide reservoir pressure maintenance. The replaced ESP at 2T-203 was successfully brought on-line in January 2008. Work to develop a full field model for Tabasco is in progress and will continue through 2008. The model will be used to optimize existing water flood and evaluate alternate recovery strategies. 57 Meltwater Field — Net Pay Map 45 '-.2P-443 2P-_434 - .. - t.Rt@2A '- - idt`LIyVZTi sp 4'7 PP E ,.'P-4512f'42,G NFFtTVX'.41EF F!'• 2P 4a2 A 2 -415 2P-448 2P-4463 �� \...._- Net Pay (ft.) 29-422A, t �4\ 10 ,1-441 2P-422 20 30 40 7P 4:8.42 50 f `nCxty " •� 6d �. ,, t �s 22P-424 L _ 2i r 70 1; _t 7 80 90 0 1 110 MILES- 0 1000 2000 3000 4000 5000 ~ �\ 120 130 �E 140 TRANSVERSE MERCATOR PROJECTION 150 G.R.S. 1980 SPHEROID CENTRAL MERIDIAN 15000 00W 160 Ma psheet datum: "UnImown" 170 5856232 �_. 1580000 1585fC0 1590000 15950CC 1597659 45 Attachment 2 Meltwater Oil Pool 2007 Annual Reservoir Surveillance Report Produced Fluid Volumes Cumulatives at Dec 31, 2006 11145637 26822622 715888 WATER OIL GAS WATER CUM OIL CUM GAS CUM WATER MO YR STB MSCF STB STB MSCF STB 1 2007 88474 176596 18407 11234111 26999218 734295 2 2007 83758 285596 27803 11317869 27284814 762098 3 2007 119332 363861 19355 11437201 27648675 781453 4 2007 103623 293851 12194 11540824 27942526 793647 5 2007 104733 257475 8586 11645557 28200001 802233 6 2007 89564 204896 10418 11735121 28404897 812651 7 2007 92219 173763 21968 11827340 28578660 834619 8 2007 85892 180553 26670 11913232 28759213 861289 9 2007 71871 134372 21380 11985103 28893585 882669 10 2007 85815 149352 17312 12070918 29042937 899981 11 2007 82772 149463 16286 12153690 29192400 916267 12 2007 82646 130570 9609 12136336`; 29322970 925876 2007 TOTAL 1090699 2500348 209988 Cumulatives at Dec 31, 2006 11145637 26822622 715888 Produced Fluid Volumes (Reservoir Units) GAS WATER OIL MO YR RVB 1 2007 118113 2 2007 111817 3 2007 159308 4 2007 138337 5 2007 139819 6 2007 119568 7 2007 123112 8 2007 114666 9 2007 95948 10 2007 114563 11 2007 110501 12 2007 110332 Produced Fluid Volumes (Reservoir Units) GAS WATER CUM OIL CUM GAS CUM WATER RVB RVB RVB RVB RVB 97535 18665 14956225 19114259 738832 187067 28192 15068042 19301326 767024 232091 19626 15227351 19533417 786650 183850 12365 15365687 19717266 799015 154200 8706 15505506 19871466 807721 119636 10564 15625074 19991103 818285 93417 22276 15748186 20084520 840561 101977 27043 15862852 20186497 867604 71965 21679 15958800 20258462 889283 77055 17554 16073363 20335517 906838 78648 16514 16183863 20414165 923352 63596 9744196 2Q475t) 90 2007 TOTAL 1456083 1461037 212928 Cumulatives at Dec 31, 2006 14838113 19016724 720167 46 Attachment 3 Meltwater Oil Pool 2007 Annual Reservoir Surveillance Report Injected Fluid Volumes Cumulatives at Dec 31, 2006 17435481 3383436 31013198 WATER MO YR WATER GAS MI CUM WATER CUM GAS CUM MI MO YR STB MSCF MSCF STB MSCF MSCF 1 2007 600841 0 201011 18036322 3383436 31214209 2 2007 569355 0 254226 18605677 3383436 31468435 3 2007 529268 0 337826 19134945 3383436 31806261 4 2007 220774 0 253691 19355719 3383436 32059952 5 2007 251466 0 206939 19607185 3383436 32266891 6 2007 229585 1 117651 19836770 3383437 32384542 7 2007 262782 0 310625 20099552 3383437 32695167 8 2007 268015 36651 157639 20367567 3420088 32852806 9 2007 247371 0 335013 20614938 3420088 33187819 10 2007 260581 0 186986 20875519 3420088 33374805 11 2007 217813 0 214542 21093332 3420088 33589347 12 2007 215163 0 172337 ZT30849 4 4200836i`„ 2007 TOTAL 3873014 36652 2748486 Cumulatives at Dec 31, 2006 17435481 3383436 31013198 WATER MO YR RVB 1 2007 609253 2 2007 577326 3 2007 536678 4 2007 223865 5 2007 254987 6 2007 232799 7 2007 266461 8 2007 271767 9 2007 250834 10 2007 264229 11 2007 220862 12 2007 218175 2007 TOTAL 3927236 Injected Fluid Volumes (Reservoir Units) GAS MI CUM WATER CUM GAS CUM MI RVB RVB RVB RVB RVB 0 160809 18288831 4096217 27398875 0 203381 18866156 4096217 27602256 0 270261 19402834 4096217 27872516 0 202953 19626699 4096217 28075469 0 165551 19881686 4096217 28241020 1 94121 20114485 4096219 28335141 0 248500 20380946 4096219 28583641 40646 126111 20652713 4136865 28709752 0 268010 20903547 4136865 28977763 0 149589 21167776 4136865 29127352 0 171634 21388639 4136865 29298985 0 137870 216fN1 '36$:ir' 2436 ` 40647 2198789 Cumulatives at Dec 31, 2006 17679578 4096217 27238066 47 1 u ' Attachment 4 Meltwater Oil Pool 2007 Annual Reservoir Surveillance Report Reservoir Pressure Surveys u 0 11 1 1 48 u n �- I I I I I I I u I I O N O w O U) a 0 oWC Z W sO U) > v+ gwU) U- Z O° �a CoO Q W o (1) W J Q z Z Q M 0 W N w CM0 LL.

There were 16 pressure surveys reported for the Meltwater Oil Pool to the AOGCC in 2007. In 2008, we expect to conduct approximately six pressure surveys, including initial surveys for new wells prior to initial sustained production. If you have any questions concerning this data, please contact Paul Burtis at (907) 265-6314. Sincerely, ames T. Rodgers Manager — GKA Light Oil Greater Kuparuk Area bcc: Central Files ATO -3 50 Attachment 5 Meltwater Oil Pool 2007 Annual Reservoir Surveillance Report Production/Special Surveys • In 2007, there were no special survey logs run at Meltwater. In 2008, data gathering logs will focus on cased -hole formation resistivity logs, in both injection wells and production wells that have cut water, evaluating which zones / lobes have been swept and which might potentially remain at initial conditions. Details of these logs will be included in the 2008 surveillance report. n 1 51 r Attachment 6 Meltwater Oil Pool 2007 Annual Reservoir Surveillance Report Results of Well Allocation, Test Evaluation, and Special Monitoring Well Allocation iMeltwater DS2P facilities were fabricated with a conventional test separator. A portable test separator system has been utilized at DS 2P to handle the solids production during initial flowback (<1 week) of the fracture stimulated producers. 0 I I A minimum of two well tests per month were taken on production wells. Test separator backpressure corrections were applied to wells that experienced greater than 100 psi backpressure over header pressure. Correction to stock tank barrel conditions were made by applying Meltwater specific pressure corrections (derived from the PVT analysis of Meltwater North #1 crude oil samples) and API temperature corrections. Miscible gas is used for injection and gas lift at DS2P. For the wells that were on MI lift during a well test, the metered liquid rates were adjusted for NGLs associated with MI lift. A Peng- Robinson equation of state calculated the NGL recycle volume based on MI volume, separator temperature and pressure. Production volumes were tracked through Setcim production monitoring systems. The 2007 Meltwater allocation factors by month are listed below.

During 2006, one additional well, 2P-406, had OA pressures that increased to anomalous levels (2_900 psig). Now a total of four of the eight Phase II injection wells (2P-406, 2P-432, 2P-434, and 2P-447) have seen elevated OA pressures. The surface pressures are monitored daily via Setcim (wells have pressure transducers that transmit the real-time OA pressures). The OA fluid levels are shot once per month. Calculations are made monthly to determine the approximate pressures in the outer annuli at the C-80 interval in each of the wells that have elevated surface OA pressures. ' This data is then sent to the AOGCC. At the beginning of 2007, plans were discussed to take additional samples from the OA's to be sent off for isotopic analysis. Throughout the year most wells exhibited relatively stable OA pressures, with the exception of 2P-406 with a gradual increasing OAP, which prompted this data gathering to commence in 2008. Upon completion, the ' results of the analysis will be compared with work done during 2003 and 2005. There are also plans to perform short term bleeds (approximately 1-3 hours) that will allow CPAI to monitor the fall-off and build-up pressures of the subject wells with elevated OA pressures. A report outlining the results of these bleeds will be submitted to the AOGCC in 2008 once this work is complete. � I I I n I I r 9 N Ste. t7S ,C7 a W v a O N f" � a co Ln Om esi u�i O m V (0 m (.[) O M V' co O h O to m CD OO C m N N N R (C1 N N N <V N N CV N CV N N N J y LL Q' < o a (S5 ttS u7 (� M N CO �4 O O O O m V O m Vy M r N O N 0 rn CDF dW � a In m r- m IN O m O M C. m Y-. m _.

Development Drilling — One or two additional development well locations have been identified and tentative plans are to pursue drilling these well locations during 2009-2011 timeframe. The total well count after the final portions of the development drilling program are completed is expected to be 20-22 wells. The acquisition of additional seismic data is currently underway for the Tarn / Meltwater area. This new seismic data will help to further evaluate the potential of the peripheral edges of the Meltwater pool, help to analyze producer -injector patterns, and identify infill potential. The total well count after the final portions of the development drilling program are completed is expected to be 20-22 wells. In 2006, it was discovered that injection wells 2P-419 and 2P-420 each had fill covering the lower perforated Bermuda intervals. This fill was unable to be circulated out with coiled tubing ' during fill clean out and milling operations; furthermore, each well had damaged casing as a result of the unsuccessful fill clean outs and milling operations. Coiled tubing sidetracks were evaluated for both of these wells in order to restore injection into the entire Bermuda interval, but it appears beneficial to wait for the seismic data to be processed and interpreted before spending additional funds on development drilling. Exploration/Delineation — No further exploration work is currently planned for the Bermuda interval. However, an appraisal well is on the rig schedule to evaluate the overlying Cairn sand. This interval is believed to be gas bearing and could prove to be beneficial in supplying fuel gas to the Kuparuk facilities. 1 55 1 ConocoPhillips March 31, 2008 Mr. Dan Seamount, Commissioner Alaska Oil and Gas Conservation Commission 333 West 7t' Ave. Suite #100 Anchorage, Alaska 99501-3539 James T.

Rodgers Manager - GKA Light Oil Greater Kuparuk Area bcc: Central Files ATO -3 56 iL �J u 1 11 Attachment 1 Kuparuk River Unit Tabasco Oil Pool 2007 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project Tabasco produced 1063 MBO of crude, 366 MMSCF of gas, and 5681 MBW during 2007. Water injection was 7707 MBW over the same period. Cumulative oil, gas, water production, and water injection through year end 2007 were 13.7 MMBO, 2.4 BCF, 46.9 MMBW, and 53.6 MMBWI, respectively. The cumulative injection/withdrawal ratio was 0.87 on a reservoir barrel basis through year end 2007. Injector 2T -217A remained shut-in waiting for post rig work to include a cement squeeze and surface facility work. Injector 2T -217A will be the second injector at Tabasco. 2T-203 had a new ESP installed in December 2007. Start up of this new ESP was not completed by year end 2007. Year end 2007 Tabasco well count (all at Kuparuk River Unit Drill Site 2T) was: Producers: 10 completed 8 on line Injectors: 2 completed 1 on line The water oil ratio (WOR) was 6.2 at the end of 2007 compared to 5.5 at the end of 2006. Water breakthrough has occurred at all eight producers. Production and injection logs, coupled with the structural positions and water breakthrough histories of the producers, suggest that the water production mechanism is dominated by gravity - induced slumping. 2T -217A will be brought on line in 2008 as the second Tabasco injector. 2T -217A is premised to provide additional flow streams to displace previously unswept oil and provide reservoir pressure maintenance. The replaced ESP at 2T-203 was successfully brought on-line in January 2008. Work to develop a full field model for Tabasco is in progress and will continue through 2008. The model will be used to optimize existing water flood and evaluate alternate recovery strategies. :M y Attachment 2 Tabasco Oil Pool 2007 Annual Reservoir Surveillance Report Produced Fluid Volumes Cumulatives at Dec 31, 2006 12680369 2011639 41216781 Produced Fluid Volumes (Reservoir Units) OIL GAS WATER CUM OIL CUM GAS CUM WATER MO YR STB MSCF STB STB MSCF STB 1 2007 117681 15729 602940 12798050 2027368 41819721 2 2007 129071 18467 585008 12927121 2045835 42404729 3 2007 120588 21762 589709 13047709 2067597 42994438 4 2007 122790 34269 628120 13170499 2101866 43622558 5 2007 125906 39077 639248 13296405 2140943 44261806 6 2007 98064 26243 568198 13394469 2167186 44830004 7 2007 82811 68617 438572 13477280 2235803 45268576 8 2007 50712 85446 270838 13527992 2321249 45539414 9 2007 26291 18833 113353 13554283 2340082 45652767 10 2007 30628 15709 129219 13584911 2355791 45781986 11 2007 61972 10075 487594 13646883 2365866 46269580 12 2007 96622 11787 6278083743ti8;;

Since production wells are completed with gravel pack screens and electrical submersible pumps, no production logs or special surveys are planned for 2008. 63 Attachment 6 Kuparuk River Unit Tabasco Oil Pool 2007 Annual Reservoir Surveillance Report Well Allocation and Test Evaluation Summary A minimum of two well tests per month was taken on production wells. Fluid samples were obtained on a regular basis, and water cut corrections were applied to well tests as required based on the subsequent lab analysis. Generally, very good agreement was observed between the phase dynamics and the shakeout analysis. Production volumes were tracked through the Setcim production monitoring system. In 2002, Tabasco switched from an allocation factor of 1.0 to floating production allocation factors. Tabasco 2007 production allocation factors were as follows: Tabasco Oil Pool 2007 Production Allocation Factors 64 Oil Gas Water Jan -07 0.9602 0.8471 1.0214 Feb -07 0.9800 0.8585 1.0469 Mar -07 0.9725 0.8623 1.0343 Apr -07 0.9706 0.8821 1.0405 May -07 0.9634 0.8699 1.0374 Jun -07 0.9545 0.8948 1.0230 Jul -07 0.9626 0.9184 0.9961 Aug -07 0.9419 1.0158 1.0176 Sep -07 0.9500 0.9164 1.0308 Oct -07 0.7063 0.6694 0.7703 Nov -07 0.9321 0.8914 1.0054 Dec -07 0.9653 0.9001 0.9991 64 Ll I Attachment 7 Kuparuk River Unit Tabasco Oil Pool 2007 Annual Reservoir Surveillance Report Future Development Plans Two new rig workovers were initiated in late 2007 for the Tabasco Oil Pool at Drillsite 2T. 2T-203 had a failed ESP replaced. 2T -217A is being converted from a producer to the second Tabasco water injection well. Both these rig workover projects will be completed in 2008. The installation of a 10" water injection pipeline (completed in 2007) to Drillsite 2T enables increased water injection support in both the Kuparuk and Tabasco reservoirs in 2008. Tabasco injection withdrawal ratios (INV ratio) will be monitored to maintain an instantaneous value of 1.0 or greater. Adjustments to injection and/or production rates will be made to maintain an instantaneous INV ratio of 1.0 or greater so that gas will remain in solution and pressure support maintained for the Tabasco reservoir. Work continues on the development of a full field model. The model will be used to evaluate the potential for infill locations on the peripheral edges of the field. Screening evaluations indicate that Tabasco development beyond Drill Site 2T is most prospective at Kuparuk River Unit Drill Sites 3H and 3G. Tabasco geologic and engineering studies in 1999 identified Drill Site 3H appraisal well locations which may be drilled in the future. Tabasco development beyond Drill Site 2T continues to prove challenging due to smaller accumulations, lower quality reservoir, and higher viscosity oil. 65 ConocoPhillips March 31, 2008 Mr. Dan Seamount, Commissioner Alaska Oil and Gas Conservation Commission 333 West 7t' Ave. Suite #100 Anchorage, Alaska 99501-3539 James T.

The Tarn Pool Rules and Area Injection Order were approved on July 21St and July 20th, 1998 respectively. The Unit Expansion and Participating area were approved effective July 1, 1998. Construction of the Tarn road, pads, powerlines, and pipelines took place in the 1998/1999 winter construction season. Tarn development drilling commenced in April of 1998. Tarn production began on July 8, 1998. Injection of miscible injectant (MI) began in November 1998. Tarn switched to a miscible water alternating gas (MWAG) recovery process in July 2001. Progress of EOR Project The permanent 12" water injection line was completed and brought on-line in July 2001. This allowed Tarn to switch from strictly an MI flood to an MWAG recovery process which increases ultimate recovery from the Tarn reservoir. Water injection capacity has been good and injectivity has remained strong with no signs of formation damage. Tarn is operating at injection pressures above ' parting pressure which enables water injection to match offtake. The Tarn MWAG process uses Kuparuk spec MI which is injected above the ' minimum miscibility pressure. For compositional analysis of the Kuparuk spec MI, refer to the Kuparuk section of the annual surveillance report. ' Reservoir Management Summary In 2007, Tarn produced 5.78 MMBO, 8.11 MMBW, and 12,104 MMSCF gas. The injection totals for 2007 were 522 MMSCF Lean Gas, 13.6 BSCF of MI and 12.7 MMBW. The cumulative year-end 2007 I/W ratio for Drill Site 2N is estimated at 1.01, while the estimated cumulative INV for Drill Site 2L is 1.26. Plans are to continue maintaining reservoir pressure by balancing monthly ' injection and production rates. 1 67 Attachment 2 Tarn River Oil Pool 2007 Annual Reservoir Surveillance Report Produced Fluid Volumes Cumulatives at Dec 31, 2006 80185733 116907206 19253030 Produced Fluid Volumes (Reservoir Units) OIL GAS WATER CUM OIL CUM GAS CUM WATER MO YR STB MSCF STB STB MSCF STB 1 2007 512777 981972 800521 80698510 117889178 20053551 2 2007 472526 929764 706543 81171036 118818942 20760094 3 2007 513277 1037955 760201 81684313 119856897 21520295 4 2007 471812 962459 741854 82156125 120819356 22262149 5 2007 435615 969148 686914 82591740 121788504 22949063 6 2007 346287 814842 436207 82938027 122603346 23385270 7 2007 524205 1250569 692736 83462232 123853915 24078006 8 2007 549705 1274530 631591 84011937 125128445 24709597 9 2007 542323 1054489 569306 84554260 126182934 25278903 10 2007 511534 982539 673223 85065794 127165473 25952126 11 2007 436965 921221 677640 85502759 128086694 26629766 12 2007 459820 924970 732847 2007 TOTAL 5776846 12104458 8109583 Cumulatives at Dec 31, 2006 80185733 116907206 19253030 Produced Fluid Volumes (Reservoir Units) 2007 TOTAL 7765428 9636995 8223117 Cumulatives at Dec 31, 2006 107504914 106441166 19522572 68 OIL GAS WATER CUM OIL CUM GAS CUM WATER MO YR RVB RVB RVB RVB RVB RVB 1 2007 688047 750054 811728 108192961 107191220 20334301 2 2007 634073 721395 716435 108827034 107912615 21050735 3 2007 688837 816761 770844 109515871 108729377 21821579 4 2007 633311 759948 752240 110149183 109489324 22573819 5 2007 585001 794424 696531 110734184 110283748 23270350 6 2007 465560 681709 442314 111199744 110965457 23712664 7 2007 703498 1058875 702434 111903242 112024332 24415098 8 2007 740178 1057491 640433 112643419 113081823 25055531 9 2007 730609 808050 577276 113374029 113889873 25632807 10 2007 688998 745304 682648 114063026 114635177 26315456 11 2007 588312 728205 687127 114651339 115363383 27002583 12 2007 619004 714778 74310712{ 2007 TOTAL 7765428 9636995 8223117 Cumulatives at Dec 31, 2006 107504914 106441166 19522572 68 Attachment 3 Tarn River Oil Pool 2007 Annual Reservoir Surveillance Report Injected Fluid Volumes 2007 TOTAL 12736234 521766 13585123 Cumulatives at Dec 31, 2006 95227305 10273621 127017038 Injected Fluid Volumes (Reservoir Units) WATER GAS MI CUM WATER CUM GAS CUM MI MO YR STB MSCF MSCF STB MSCF MSCF 1 2007 1115198 0 1445481 96342503 10273621 128462519 2 2007 1040035 0 1246754 97382538 10273621 129709273 3 2007 978688 0 1639021 98361226 10273621 131348294 4 2007 816677 0 1387430 99177903 10273621 132735724 5 2007 813749 0 1608120 99991652 10273621 134343844 6 2007 751524 162434 1439234 100743176 10436055 135783078 7 2007 845391 0 1023901 101588567 10436055 136806979 8 2007 1230497 359332 459667 102819064 10795387 137266646 9 2007 1302695 0 404867 104121759 10795387 137671513 10 2007 1474537 0 145421 105596296 10795387 137816934 11 2007 1314832 0 944710 106911128 10795387 138761644 12 2007 1052411 0 184051787969 '953$1 , 4t1E2'f 2007 TOTAL 12736234 521766 13585123 Cumulatives at Dec 31, 2006 95227305 10273621 127017038 Injected Fluid Volumes (Reservoir Units) 2007 TOTAL 12914541 590957 11074612 Cumulatives at Dec 31, 2006 96560491 11643948 103814432 69 WATER GAS MI CUM WATER CUM GAS CUM MI MO YR RVB RVB RVB RVB RVB RVB 1 2007 1130811 0 1182808 97691302 11643948 104997240 2 2007 1054595 0 1011444 98745897 11643948 106008684 3 2007 992390 0 1333314 99738287 11643948 107341998 4 2007 828110 0 1134012 100566397 11643948 108476010 5 2007 825141 0 1315097 101391539 11643948 109791107 6 2007 762045 184072 1175125 102153584 11828020 110966231 7 2007 857226 0 837820 103010811 11828020 111804051 8 2007 1247724 406885 369876 104258535 12234905 112173927 9 2007 1320933 0 330775 105579467 12234905 112504703 10 2007 1495181 0 119827 107074648 12234905 112624529 11 2007 1333240 0 770603 108407888 12234905 113395132 12 2007 1067145 0 1493912'0475> 239ii 1889045 2007 TOTAL 12914541 590957 11074612 Cumulatives at Dec 31, 2006 96560491 11643948 103814432 69 n r 7 Attachment 4 Tarn Oil Pool 2007 Annual Reservoir Surveillance Report Reservoir Pressure Surveys 1 70 1 0 1 N 10 a IoUJ U Z W IfiVi gLLI �co) L.

The program consisted of two producer sidetracks (2N -337B and 2N -311A), one dedicated injector (2N-310), an optional injector -producer (2L-319) and four producers (2N-342, 2N-327, 2L- 327, 2L-330). Additionally, three wells tested a deep newly recognized potential reservoir within the Tarn Pool, informally named the 'Esker' interval (2N-327, 2N-310, and 2L-330). Results of the Esker tests are under review. 2N -337B replaced the 2N -337A sidetrack, which had failed to produce due to migration of formation fines and lower than expected reservoir quality. 2N -337B encountered a pressurized water zone with a direct response to the 2N-343 offset injector and has been shut-in. The 2N -311A was a twin of the 2N-311 which had been plugged and abandoned without test based on previous log analysis. Subsequent reservoir quality calibration led to the 2N -311A, a successful producer. The 2N-342 targeted a promising seismic anomaly adjacent to the main Tarn Field with similar attributes named 'Tarn South'; flow testing was successful although production issues have resulted in this well currently being shut-in. The 2N-310 was drilled in an outboard opportunistic location allowing the first flow testing of the overlying 'Cairn' interval with later primary well function as an injector supporting the current 2N-304 producer plus three potential future offset producer locations in the Tarn (Bermuda) reservoir. Due to new structural mapping and geochemical analysis of the 2L-309PB1 showing the 2L gas cap to be smaller than previous interpretations, the 2L-327 was targeted to access potential high-quality reservoir in an under -appraised portion of the 2L area. The successful 2L-327 was the highest initial rate producer at the 2L pad. 2L-319 was drilled as an optional pre -produced injector or dedicated producer, pending well performance. The 2L-330 producer targeted a potential overlapping portion of the Tarn Field between the 2L and 2N turbidite accumulations; testing is pending. Opportunities to maximize Tarn Field recovery while preventing physical waste are under constant evaluation as the field matures, geologic and reservoir performance information is assimilated, and as technology improves. Plans for 2008 include a drilling program consisting of four new wells on Tarn drillsites, 2L and 2N. A portion of these penetrations would test the productivity of the peripheral edges of the field. An update of the geologic and full -field reservoir model together with the new 2008 3D seismic is being considered for use in development planning and flood optimization. 1 75 1 Producer to Injector Conversions — Depending on the 2L-319 short-term performance, 2L-311 might be converted to an injector in 2008. Artificial Lift — Tarn was originally designed to use miscible gas (MI) as a means of gas lifting the production wells. However, paraffin deposition in the tubing string section that runs across the permafrost occurs when the production fluid temperature falls below the cloud point of 92 degF. This is the case of longer reach wells and lower liquid rate production wells. Excessive paraffin build-up and the high frequency of required paraffin scrapes in some wells led to a change in artificial lift methodology towards surface -powered downhole jet pumps. In 2001, after successful pilot tests in 1999 and 2000, 13 of the artificial lifted wells were converted to jet pump using hot produced water ' as power fluid. This technique has proven to be very successful in mitigating paraffin deposits. Slickline scrapes and hot oil treatments have been virtually eliminated leading to production increases of about 10%. Unfortunately the untreated saline produced water injected down the inner annuli (power fluid) has accelerated Itubing and casing corrosion. Three (3) well integrity failures occurred on jet -pumped wells due to both tubing and casing corrosion in 2006-2007: 2L-321, 2N-318 and 2N-305. These wells were shut-in and secured. 2N-305 and 2N-318 are candidates to be sidetracked in 2008. A workover is planned for 2L-321 during 2008. LConsequently, completion designs and alternatives to jet pumps are being considered for new and existing wells. Capillary tubes have been installed in ' several new wells. This will enable lower productivity, lower temperature, gas - lifted wells to produce with reduced paraffin deposition problems when a chemical (paraffin inhibitor) is injected down the capillary tube to treat produced oil flowing up the tubing. After water breaks through in a producing well, the need for jet pumps and other means of paraffin inhibition or removal may not be necessary. because water has a higher heat capacity and the overall higher production rate yields higher flowing temperatures. Plans to convert wells after water break -through back to gas lift are under way. In 2007, 2L-307 was converted from jet pump back to gas lift. 76 � ConocoPhillips March 28, 2008 ' Mr. Dan Seamount, Commissioner Alaska Oil and Gas Conservation Commission 333 West 7th Ave. Suite #100 Anchorage, Alaska 99501-3539 I I Blaine M.

Campbell Supervisor — Heavy Oil Development Greater Kuparuk Area bcc: Central Files ATO — 3 77 Attachment 1 Kuparuk River Unit West Sak Oil Pool 2007 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project At the end of 2007 there were 52 active water injectors and 51 active producers in the West Sak oil pool. Of those wells, 14 injectors and 15 producers were active at Drill Site 1J at the end of 2007. This represents an increase of 6 active producers and 7 active injectors within the West Sak pool from January 2007 to December 2007. The following wells were drilled and completed in 2007 into the West Sak oil pool: Name Well Type Target Service 1J-103 Multilateral D/B/A Sand Producer 1J-105 Multilateral D/B/A Sand Injector 1J-107 Multilateral D/B/A Sand Producer 1J-118 Multilateral D/B/A Sand Injector 1J-120 Multilateral D/B/A Sand Producer 1J-122 Multilateral D/B/A Sand Injector 1J-135 Multilateral D/B Sand Producer 1J-136 Multilateral D/B Sand Injector 1J-158 Multilateral D/B Sand Producer 1 J-160 Multilateral D/B Sand Injector ' 1J-162 Multilateral D/B Sand Producer 1J-176 Multilateral D/B Sand Injector 1J-180 Multilateral D/B Sand Injector Waterflooding the reservoir with CPF-1 produced water for pressure maintenance and improved sweep continues to be the main enhanced oil recovery mechanism in the West Sak oil pool. Waterflood performance was good in the majority of the patterns; however, two additional rapid water breakthrough events occurred in 2007. These events created high conductive pathways between an injector and a producer, otherwise known as a matrix bypass event. A list of the matrix bypass events in 2007 is provided below: Injector Producer Event Date Breakthrough Zone 1C-174 1C-178 June 2007 B Sand 1J-164 1J-168 Dec. 2007 B Sand Studies to understand the mechanism of these matrix bypass events is ongoing. Yp . 9 g Some early recommendations to mitigate future matrix bypass events were 78 C implemented and the pace of these events has dropped off significantly. A remediation strategy is in development for these wells, as well as others that previously have failed. During 2003, ConocoPhillips Alaska, Inc. received approval to commence a West Sak Small Scale EOR (SSEOR) Pilot Project using Kuparuk MI in a water - alternating gas (WAG) pilot. The SSEOR Pilot Project is completed. The feasibility of future gas injection into West Sak Drill sites 1E & 1 J is under ' evaluation. Request for an area injection order for parts of Drill Sites 1 E & 1 J is planned in 2008 and commencement of gas injection into these areas, pending AOGCC approval, is targeted for the 4th quarter of 2008. 79 Attachment 2 West Sak Oil Pool 2007 Annual Reservoir Surveillance Report Produced Fluid Volumes Cumulatives at Dec 31, 2006 27450187 11800304 6145353 80 OIL GAS WATER CUM OIL CUM GAS CUM WATER MO YR STB MSCF STB STB MSCF STB 1 2007 632445 483774 97626 26299185 13268551 6242979 2 2007 475246 394928 80118 26774431 13663479 6323097 3 2007 586935 443725 145657 27361366 14107204 6468754 4 2007 605602 482993 101131 27966968 14590197 6569885 5 2007 615488 430724 116859 28582456 15020921 6686744 6 2007 588119 351594 115503 29170575 15372515 6802247 7 2007 645502 424313 114521 29816077 15796828 6916768 8 2007 353321 223102 56445 30169398 16019930 6973213 9 2007 368730 209640 59028 30538128 16229570 7032241 10 2007 399262 197522 65839 30937390 16427092 7098080 11 2007 596260 250240 121321 31533650 16677332 7219401 12 2007 548406 231989 110594 32082Q ,„6114.4x$ 799 2007 TOTAL 6415316 4124544 1184642 Cumulatives at Dec 31, 2006 25666740 12784777 6145353 Produced Fluid Volumes (Reservoir Units) OIL GAS WATER CUM OIL CUM GAS CUM WATER MO YR RVB RVB RVB RVB RVB RVB 1 2007 675451 597382 97626 28125638 12397686 6242979 2 2007 507563 502425 80118 28633201 12900111 6323097 3 2007 626847 547391 145657 29260048 13447502 6468754 4 2007 646783 602659 101131 29906831 14050161 6569885 5 2007 657341 516012 116859 30564172 14566173 6686744 6 2007 628111 396792 115503 31192283 14962965 6802247 7 2007 689396 495810 114521 31881679 15458775 6916768 8 2007 377347 260036 56445 32259026 15718811 6973213 9 2007 393804 231284 59028 32652830 15950094 7032241 10 2007 426412 204012 65839 33079241 16154106 7098080 11 2007 636806 228433 121321 33716047 16382539 7219401 12 2007 585698 216351 110594 = f 2007 TOTAL 6851557 4798586 1184642 Cumulatives at Dec 31, 2006 27450187 11800304 6145353 80 Attachment 3 West Sak Oil Pool 2007 Annual Reservoir Surveillance Report Injected Fluid Volumes Cumulatives at Dec 31, 2006 39014824 0 334962 81 WATER GAS MI CUM WATER CUM GAS CUM MI MO YR STB MSCF MSCF STB MSCF MSCF 1 2007 837118 0 0 39851942 0 447212 2 2007 745948 0 0 40597890 0 447212 3 2007 819276 0 0 41417166 0 447212 4 2007 795776 0 0 42212942 0 447212 5 2007 843308 0 0 43056250 0 447212 6 2007 827147 0 0 43883397 0 447212 7 2007 990295 0 0 44873692 0 447212 8 2007 826157 0 0 45699849 0 447212 9 2007 858558 0 0 46558407 0 447212 10 2007 843906 0 0 47402313 0 447212 11 2007 791192 0 0 48193505 0 447212 12 2007 804008 0 0 2007 TOTAL 9982689 0 0 Cumulatives at Dec 31, 2006 39014824 0 447212 Injected Fluid Volumes (Reservoir Units) WATER GAS MI CUM WATER CUM GAS CUM MI MO YR RVB RVB RVB RVB RVB RVB 1 2007 837118 0 0 39851942 0 334962 2 2007 745948 0 0 40597890 0 334962 3 2007 819276 0 0 41417166 0 334962 4 2007 795776 0 0 42212942 0 334962 5 2007 843308 0 0 43056250 0 334962 6 2007 827147 0 0 43883397 0 334962 7 2007 990295 0 0 44873692 0 334962 8 2007 826157 0 0 45699849 0 334962 9 2007 858558 0 0 46558407 0 334962 10 2007 843906 0 0 47402313 0 334962 11 2007 791192 0 0 48193505 0 334962 12 2007 804008 0 0 2007 TOTAL 9982689 0 0 Cumulatives at Dec 31, 2006 39014824 0 334962 81 ' Attachment 4 West Sak Oil Pool 2007 Annual Reservoir Surveillance Report Reservoir Pressure Surveys 82 t 0 / E / N Z-- § \ / � 17 � � kk a� y t §� \ 2 Ci e 7 § kk % 6 6 6 6 6 6 6 .

West Sak wells 1J-174 (dual lateral producer), and 3K-102 (dual lateral producer) were drilled and completed with rig Doyon 15 in early 2008 and are either currently on production or in the process of being hooked up. The 1J-174 was the final well in the West Sak 1J drilling program. The Doyon 15 rig is currently drilling the 1 D -141A producer sidetrack. This sidetrack is being drilled to capture lost production/ reserves due to the junction failure on the original ID -141 well. The Doyon 15 will drill the IC -172A sidetrack following the 1D - 141A drilling operations. Offset injectors to the 3K-102 producer (3K-103 and 3K-108) will be drilled at the start of 3Q2008. The three West Sak 3K wells to be drilled in 2008 are targeting completion of the first pattern within the 3K Phase 1 development area. Two additional wells (1 producer & 1 injector) will be drilled in 1 Q2009 to complete the 3K Phase 1 development. Information regarding the expected 2008 well program is listed below: Name Well Type Target(s) Inj/Prod 1J-174 Multi -Lateral "D & B" Sands Producer 3K-102 Multi -Lateral "D & B" Sands Producer ID -141A Single -Lateral "D" Sands Producer 1C -172A Multi -Lateral "A4/ A3/ A2" Sands Producer 3K-103 Multi -Lateral "D & B" Sands Injector 3K-108* Multi -Lateral "D & B" Sands Injector *Includes two exploration sidetracks to test oil presence and quality within the two fault blocks immediately north of the 3K Phase 1 development area. • UGNU PILOTS/ STUDIES Attempts were made during 2007 to produce the 1 H-Ugnu1 well. A new downhole electric submersible progressive cavity pump (ESPCP) was installed in the well during the first half of 2007. Successful production operations were accomplished through the use of diesel "slip streaming" down the annulus to act as diluent to help lift the well. Samples were taken during production periods with little diesel contamination and have been sent to the lab for geochemical analysis, with analytical results pending. Plans for 2008 include testing an induction heater in this well, which will require a rig workover to pull the current completion and re -run the new downhole induction heater configuration. Evaluations and planning are progressing for an additional Ugnu cold production horizontal pilot well (11-1-502), which is currently anticipated to spud during the second quarter of 2009. Also, subsurface studies and facilities/ 95 well engineering are ongoing to progress conceptual design for a thermal pilot in the DS -30 area. Resource wide subsurface description (reservoir & oil quality) activities are progressing which will enable a more robust analysis of ' the resource target and required piloting design/ technologies. 11 11 J L 11 1 96
