OrillingEngineer: Aras Worthington, 564-4102 INSTRUCTIONS GENERAL: This form is designed for submitting a complete and correct well completion report and log on ail types of lands and leases in Alaska. ITEM 1a: Classification of Service Welis: 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 elevation in feet above mean low low water. 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: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: 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 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

On item 3, the 5-112" shoe is at 7925 which is what your drawing and text shows. The 10' difference is for the 3-1/2", but you are not going that deep. Thanks for looking in to these points. Most are not critical, but as this shows it is possible to "pass on" errors. I had a workover I was doing on M pad and the drawing indicated there was 9-5i8" in the well, but whenever I circulated it always took longer to "get bottoms up". I went to where BP kept their records and got the original file and found out that this was a well with "thermocase" in it. Essentially I should have been using 10-3/4" for my calculations. Volumes were close, but short. There often is worth going back to square 1 when there have been a lot of changes in a well.

Item 3: The 3 112" shoe is indeed 7925 ;not 3450" as in my drawing; i got that from the schematic which is incorrect in this case. - I will correct my drawing, Item #~: My drawing is not descriptive ofi the 3 112" liner top details; i# is just to give an idea of what the completion looks like as it pertains to the GTD operation {in this case -not critical for our 1 of 2 1/19/2006 3:14 PM Re: [Fwd: 3H-14B laterals] operation}. • Item #5: You are correct that the 7" window is 6227°, the completion report for 3H-14B is apparently wrong in stating 6039`. The drilling text clearly reads 6227' as T4t!!/J. - I will correct this on my drawing.

Just a couple of "points" after looking at the files. 1. I was able to confirm the shoe depth for the 5-1/2" liner. 2. There seems to be a discrepancy about the top of the 5-1/2" liner. 6039 and 6010 appear in the narrative report provided with the 3H-14B 407. 6039 is what you show on the 401 and I agree that is probably correct. I don't have any tallies to reference. 3. There maybe a 10' discrepancy on the shoe depth of the 3-1/2" liner. Your drawing shows 8450' and that is the TD tagged when the liner was run. The shoe could have been set 10' off bottom and that may be reflected in the liner tallies that are not in the file I have. 4. Your drawing doesn't show the 3-1/2" as a liner with the top at 7780 (according to the 401 for 3H-14BL1). 5. Your drawing shows a 7" shoe to be at 6039'. This is one of the possible liner top depths, but the 7" actually extends deeper. The top of the window according the the completion report is 6227'. Please give me a call if you'd like to discuss. I don't think these issues are critical here since all your coil work will be conducted inside the 3-1/2" liner well away from any other tubulars. But, as I point out, there appear to be some differences with the "text numbers" on the 401 and the drawing.

Well Control: • Two wellbore volumes (250 bbls) of KWF will be location during drilling operations. • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4500 psi. • The annular preventer will be tested to 400 psi and 2500 psi. Directional • See attached directional plans for 3H-14BL1, 3H-14BL2, & 3H-14BL3. ° • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • The neazest well to 3H-14BL1 is 3H-14, which is offset by 700'. KRU boundazy is 27,300' away. • The nearest well to 3H-14BL2 is 3I-16, which is offset by 1800'. KRU boundary is 27,300' away. • The nearest well to 3H-14BL3 is 3I-16, which is offset by 1800'.

' Hazards i • 3H is an H2S pad, the highest H2S measurement on the pad is 450 ppm. All H2S monitoring equipment will be operational. Reservoir Pressure ~ • The expected reservoir pressure of 3H-14B (Ll, L2, & L3) is 5000 psi at 6071' TVD, 15.9 ppg EMW. ~" Max. surface pressure with gas (0.1 psi/ft) to surface is 4400 psi. DOBCTD Pressure Drilling Dynamically overbalanced pressure drilling (DOBCTD) techniques will be employed to provide constant ' bottom hole pressure by using 9.9 ppg drilling fluid in combination with annular friction losses and applied surface pressure. Constant BHP will be used to reduce pressure fluctuations to help with hole stability. Applying annular friction and choke pressure also allows use of less expensive drilling fluid and minimizes fluid losses and/or fracturing at the end of the long wellbores. A hydraulic choke for regulating surface pressure will be installed between the BOPE choke manifolding and the mud pits and will be independent of the BOPE choke. Using this technique will require deployment of the BHA under trapped wellhead pressure. Pressure deployment of the BHA will be accomplished utilizing the BOP pipelslips (2 3/8" rams, see attached BOP configuration). The annular preventer will act as a secondary containment during deployment and not as a stripper. Estimated max reservoir pressure: 5000 psi at 6071' TVD, 15.9 ppg EMW. Expected annular friction losses while circulating: 720 psi. Planned mud density: 9.9 ppg equates to 3125 psi hydrostatic bottom hole pressure. While circulating 9.9 ppg fluid, bottom hole circulating pressure will be kept at an estimated 5100 psi or 16.lppg ECD. , When circulation is stopped, a minimum of 1250 psi surface pressure will be applied to maintain constant BHP. Operating parameters and fluid densities will be adjusted based on real-time bottom hole pressure measurements and shale behavior while drilling.

(2) All depths are Bit Depths unless otherwise noted. (3) All Gamma Ray data (GRAX) presented is realtime data. (4) Baker Hughes INTEQ utilized CoilTrak downhole tools and the advantage surface system to log this well. (5) Tools ran in the string included Casing Collar Locator, and Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Directional, Outer Downhole Pressure, and Downhole Weight on Bit), a and Gamma Sub, and a Hydraulic Orienting Sub with a near Bit Inclination Sensor. (6) Data presented here is final and has not been depth adjusted to a PDC (Primary Depth Control) log. The INTEQ MWD Gamma Ray is the PDC for this wellbore. (7) This well was drilled from 3H-14B through a milled window in 7" liner: Top of Window 8025.0 ft.MD (5994.9 ft.5STVD) Bottom of Window 8027.8 ft.MD (5996.9 ft.SSTVD) (8) The interval from 10743 ft.MD to 10774 ft.MD (6086.5 ft.SSTVD to 6090.0 ft.SSTVD) was not logged due to bit to sensor offset at TD.
