Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item la: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box.

Well X-19B was drilled as a rotary sidetrack in 1996. Two laterals were drilled. One accessed the Ivishak Zone 4B and the other was a test lateral drilled in the Shublik. The Zone 4B lateral was completed with 41/2" liner cemented and perforated while the Shublik lateral was completed with 41" slotted liner. A production profile run in December 1996 shortly after the well was completed showed that the Shublik lateral was not contributing to production. The initial oil rate was high, with small percentage watercut and low GOR. X-19B has had a major declined in oil rate, with an increase in both watercut GOR. Well X-19B has a history of poor tubing integrity. The well repeatedly failed TIFLs, and MIT-Ts between 1999 and 2007. During this time, the well operated under a waiver for TxIA communication. In 6/07 a LDL identified a leak in the pup joint above the Tx 4-1/2" packer at 11,181'. A patch was set from 11,163'-11,196' and a MIT-IA passed. In March 2009, the well failed a MITT. Diagnostics showed that the tree was the leak path and a Cameron tree replacement in 4/09 restored wellbore integrity. The well has been on production with no integrity issues since that date. A caliper was run 1/18/10 to inspect the 4.5" tubing and 7" liner. The caliper showed that the tubing was in good to fair condition with wall penetrations ranging from 20-30%. No significant ID restrictions were recorded. The 7" liner is in fair condition with wall penetrations ranging from 29-33%. A coil tubing sidetrack will enable this 41/2" monobore to be more effectively utilized and bring value to the field. The multilateral sidetrack, X-19B L2 & L2-01, is scheduled to be drilled by Nordic 2 starting on September 11th, 2010. This multilateral will target_Ivishak Zone 4B. Kick off is at the top of Zone 4 in existing perforations. A KB packer will be set by CTD in blank pipe below, a spacer and tray will be snap latched in and oriented to the high side for best retrievability. The first lateral will make a hard 20DLS left turn and undulate in Zone 4. A slotted liner with aluminum billet on top will be run and dropped off outside the window. The second lateral will be drilled off the aluminum billet to and make a 30DLS hard right turn. The second lateral will be completed with a slotted liner dropped off outside the window. The whipstock and packer will be recovered by the drilling rig and the 4-1/2" nipple reducer and KB patch re-run post rig. .The following describes work planned. A schematic diagram of the proposed sidetrack is attached for reference. CTD Sidetrack Summary Pre-CT Rig Work: The pre CTD work is planned to begin August 2091, 2010. 1.

Directional • See attached directional plan. Maximum planned hole angle for X-19BL2 is 92° at 13,016' MD and 97° at 12,020' MD for X-19BL2-01. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 10,135'for X-19BL2, 10,915'for X-19BL2-01 • Distance to nearest well within pool —915' from X-19BL2 to TSAD in heel X-36i. 1,165' from X-19BL2-01 to TSAD in heel X-20A. Anti-Collision • X-19BL2 o X-36 788' (ctr—ctr distance) Status: Water injector injecting. • X-19BL2-01 o X-19BL1 47' (ctr—ctr distance) Status: Slotted liner in parent well. o X-19BPB1 60' (ctr—ctr distance) Status:Abandoned. o X-20 619' (ctr—ctr distance) Status: Abandoned. o X-20A 619' (ctr—ctr distance) Status: Water injector injecting. o X-20PB1 619' (ctr—ctr distance) Status: Abandoned. Logging • MWD directional, Gamma Ray and Resistivity logs will be run over all of the open hole section. Hazards • X Pad is an H2S drill site. H2S levels have reached 100 ppm and more. • The maximum recorded H2S level on X Pad was 115 ppm on well X-02 (January 10th, 2010). High reading on X-02 is attributed to H2S in injection gas. • Most recent H2S level ON X-19B was 20 ppm on October 3rd, 2009. • The lost circulation risk in the X-19B L2 laterals is considered to be low due to the history of minimal Zone 4 lost circulation problems in the parent well X-19B and in the surrounding area. No significant fault crossings are anticipated in either the L2 or L2-01, though both laterals have one possible small (<10') fault crossing (or fracture zone). Reservoir Pressure • The reservoir pressure is estimated to be 3,340 psi at 8,971 TVDss (7.2 ppg equivalent). • • Max expected surface pressure with gas (0.10 psi/ft)to surface is 2,443 psi.
