Well 3N -16A has not been perforated — it was drilled to the top of the A -sand and cased/cemented in anticipation of future CTD operations. Four proposed A -sand CTD laterals will access an area that is without injection support for improved sweep efficiency and reserve recovery. Prior to drilling the 3N -16A CTD sidetracks, service coiled tubing will drill out the shoe track of the 3 production liner. Well 3N -16A has already passed an MIT -IA and MIT -T, and has had a cement bond log run confirming excellent cement. Please note that the packer placement in well 3N -16A is not as prescribed in 20 AAC 25.412(b): it is substantially more than 200' away from the planned kick -off point for the CTD laterals. Administrative approval is requested to allow water injection into the 3N -16A laterals given the existing packer placement. The 3N -16AL1 lateral will exit the 3%2" liner via a mechanical whipstock at 8170' MD. The lateral will target the A2 sand northeast of the existing well with a 1423' lateral. The hole will be completed with a 2W slotted liner to the TD of 9593' MD with a liner top aluminum billet at 8785' MD. The 3N- 16AL1 -01 lateral will kick off from the aluminum billet at 8785' MD and will target the A3 sand northeast of the existing well with a 940' lateral. The hole will be completed with a 2%" slotted liner to the TD of 9725' MD with a liner top aluminum billet at 8240' MD. The 3N- 16AL1 -02 lateral will kick off from the aluminum billet at 8240' MD will target the A2 sand southeast of the existing well with a 1099' lateral. The hole will be completed with a 2W slotted liner to the TD of 9339' MD with a liner top aluminum billet at 8440' MD. The 3N- 16AL1 -03 lateral will kick off from the aluminum billet at 8440' MD and will target the A3 sand southeast of the existing well with a 948' lateral. The hole will be completed with a 2%" slotted liner to the TD of 9388' MD with the final liner top located just inside the 3 liner at 8165' MD.

Reservoir Pressure • There have not been any pressure surveys taken in 3N -16A since it has never been perforated. Recent pressure surveys in the target fault block indicate very low bottom hole pressure. A survey in 3N -19 measured A -sand reservoir pressure of 1252 psi at 6346' SSTVD, corresponding to 3.8 ppg EMW. The last pressure survey in 3N -15 measured pressure of 1001 psi at 6400' SSTVD, corresponding to 3.0 ppg. We generally expect to encounter similar pressure as the laterals are drilled away from the mother well. Page 3 of 6 O R I I N r L August 10, 2010, FINAL • KRU 3N- 16AL1, AL1 -01, AL1 -02, AL1 -03 — Coiled Tubing Drilling Well Control: • Two well bore volumes ( -470 bbl) of KWF will be available to the rig during drilling operations. The kill weight fluid may or may not be stored onsite, but if it is stored offsite it will be in the Kuparuk Field within a short drive to the rig. • BOP diagram is attached for operations with 2" coil tubing. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. Maximum potential surface pressure in 3N -16A is 2663 psi assuming a gas gradient to surface and maximum potential formation pressure. Maximum potential formation pressure is based on the original pressure measured in well 3N -19, which is 3283 psi at 6200 SSTVD (i.e. 10.2 ppg) in February 2002. • The annular preventer will be tested to 250 psi and 2500 psi. Directional: • See attached directional plans: 1. 3N- 16AL1, plan #4 2. 3N- 16AL1 -01, plan #5 3. 3N- 16AL1 -02, plan #6 4. 3N- 16AL1 -03, plan #5 • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • 3N -16A northeastern CTD laterals (AL1 & AL1 -01): —8130' to property line, —1350' to well 3N -15 • 3N -16A southeastern CTD laterals (AL1 -02 & AL1 -03): —8800' to property line, —1600' from well 3N -19 Hazards • Lost circulation is a major concern in 3N -16A because of the very low reservoir pressure in the A -sand. Losses will be tolerated as best as is possible, but if it becomes impossible to drill ahead then we'll complete the well with slotted liner across whatever hole has been drilled. We could then return to drill the remaining laterals after the well has been on injection for a significant period of time. • Shale stability is a potential problem, particularly in the build section where the A5 shale will be encountered. Will mitigate potential sloughing problems by cutting this interval at less than 70° hole angle. • There has been no injection into the target fault block nor has the 3N drillsite ever been equipped to inject MI gas. Therefore, it is unlikely that an influx could yield significant quantities of gas. • Well 3N -16A has no measured H since it has not been perforated or produced since being sidetracked in July 2010. Prior to being sidetracked well 3N -16 had 140 ppm measured H as of 12/15/08. Well 3N -15 is located 25' to the right side and 3N -17 is 25' to the left side of the 3N -16A surface location. Well 3N -15 has 150 ppm H and 3N -17 has 120 ppm H both being measured in Nov -09. The maximum H level on the pad is 220 ppm from well 3N -01 (12/11/09). All H monitoring equipment will be operational. Page 4 of 6 Y om + R! Gir August 10, 2010, FINAL • • KRU 3N- 16AL1, AL1 -01, AL1 -02, AL1 -03 — Coiled Tubing Drilling Managed Pressure Drilling Managed pressure drilling (MPD) techniques will be employed to provide constant bottom hole pressure by using 8.6 ppg drilling fluid in combination with annular friction losses and applied surface pressure. Constant BHP will be utilized to reduce pressure fluctuations to help with hole stability. Applying annular friction and choke pressure also allow use of less expensive drilling fluid and minimizes fluid losses and /or fracturing at the end of the long well bores. A hydraulic choke for regulating surface pressure is installed between the BOPE choke manifold and the mud pits, and is independent of the BOPE choke. Using this technique will require deployment of the BHA under trapped wellhead pressure. Pressure deployment of the 2%" BHA will be accomplished utilizing the 2%" pipe rams and slip rams. The annular preventer will act as a secondary isolation during deployment and not as a stripper. The SCSSV in well 3N -16A will enable us to deploy slotted liner without having to kill the well. Operating parameters and fluid densities will be adjusted based on real -time bottom hole pressure measurements while drilling and shale behavior. The following scenario is expected at TD: • Expected reservoir pressure is 1200 psi at 8170' MD (6403' SSTVD), or 3.6 ppg EMW. • Expected annular friction losses while circulating: 819 psi (assuming annular friction of 100 psi /1000 ft due to the 31/2" tubing) • Planned mud density of 8.6 ppg equates to 2870 psi hydrostatic bottom hole pressure at 6403' SSTVD • While circulating 8.6 ppg mud, bottom hole circulating pressure is estimated to be 3689 psi or 11.1 ppg EMW without holding any additional surface pressure. This is sufficient to overbalance expected formation pressure in 3N -16A. If increased formation pressure is encountered, mud weight or choke pressure will be increased to maintain overbalance. Additional choke pressure or increased mud weight may also be employed for improved borehole stability, but not necessarily for well control. • When circulation is stopped, —820 psi of surface pressure would have to be applied to maintain the same borehole pressure as during drilling operations. Quarter -Mile Injection Review The following wells lie within one - quarter mile of the proposed 3N -16A CTD laterals. • 3N -16 (plugged & sidetracked) — Plugged A -sand and C -sand perfs in April/May 2010 in anticipation of a rotary sidetrack. Placed a total of 30 bbl of class `G' cement and achieved 1500 psi squeeze pressure. • 3N -16A (suspended injector and motherbore of the CTD laterals). This well was recently TD'd and cased down to 8190' MD, 6478' TVD which is in the B -sand above the target horizon of these CTD laterals. The cement bond log of 7/22/2010 shows generally excellent cement across the 31/2" liner up to 5564' MD. A liner -top packer at 4666' MD ties the 31/2" liner into the 7" casing. The well has already passed a MIT -IA (7/11/10) and State - witnessed MIT -T (8/7/10). The passing MIT -T confirms liner integrity between the top of cement at 5564' and the liner -top packer at 4666'. Please note that - ConocoPhillips requests administrative approval to allow waterflood injection into 3N -16A even though the packer is more than 200' away from the kick -off point as per 20 AAC 25.412(b). • 3N-16A-PB1 — Drilled from 4950' to 8260' MD (6478' TVD). It was TD'd in the B -sand above the target injection horizon of these CTD laterals. The borehole was abandoned due to shales falling apart. Ultimately stuck 5'/2" liner in this borehole from 5328' — 7528'. A cement retainer was set inside the 51/2" liner at 5360' MD. It is highly likely that sloughing shales will have packed off against the 51/2" liner, preventing fluid migration uphole to other hydrocarbon bearing intervals. Page 5 of 6 t I t' A August 10, 2010, FINAL • • KRU 3N- 16AL1, AL1 -01, AL1 -02, AL1 -03 — Coiled Tubing Drilling • 3N- 16A -PB2 — Accidentally sidetracked from the 3N- 16A -PB1 wellbore at 7740' MD and drilled to 7833' MD (6249' TVD) before confirming accidental departure. It was TD'd in the D -shale above the target injection horizon of these CTD laterals. The 5 liner that got stuck in the 3N- 15A -PB1 borehole straddled the sidetrack point of this plugback, so likewise it should provide isolation to uphole intervals. Also, since this plugback was TD'd 214' vertically above the proposed kickoff depth of the 3N -16A CTD laterals there should be no opportunity for direct communication with the CTD laterals. • 3N- 16A -PB3 — Sidetracked from the 3N- 16A -PB1 borehole from 5195' to 8180' MD (6472' TVD). It was TD'd in the B -sand above the target injection horizon of these CTD laterals. Abandoned due to shales falling apart. Placed a 36 bbl cement plug from 6600' — 7600' MD. Also set a cement retainer inside the 7" casing at 4900' MD, and squeeze 51 bbl of cement through this retainer. • 3N -14A — Sidetracked from the 3N -14 wellbore in October/November 2007 and drilled to 8220' MD (6647' TVD). This well is a producing single completion in the Kuparuk A -sand. The Kuparuk sands are isolated by cemented 3'/2" liner. • 3N-14A-PB1 — Hole was drilled to 7768' MD, 6232' TVD in October 2007. The 5 liner became stuck at 4310' to 7274'. A stinger was used to spot a 21.4 bbl cement plug on top of the stuck liner in order to isolate the plugback and kickoff the 3N -14A borehole. Since this plugback was TD'd 231' vertically above the proposed kickoff depth of the 3N -16A CTD laterals there should be no opportunity for direct communication with the CTD laterals. • 3N -15 — This well is a producing single completion in the Kuparuk A -sand. It is isolated by cemented 7" casing across the Kuparuk sands. Page 6 of 6 ORIGINAL August 10, 2010, FINAL r .. • KU P • 3N -16A ConocoPhillips 1 Well At rigutes Max Angle & MD TO A{ f",4k13 F.'
