Dear Mr. Tirpack:
Enclosed is the approved application for permit to drill the above referenced
development well.
The permit is for a new wellbore segment of existing well PBU W-204, Permit No.
206-158, API No. 50-029-23333-00. Production should continue to be reported as
a function of the original API number stated above.
This permit to drill does not exempt you from obtaining additional permits or an
approval required by law from other governmental agencies and does not authorize
conducting drilling operations until all other required permits and approvals have
been issued. In addition, the Commission reserves the right to withdraw the
permit in the event it was erroneously issued.
Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter
25 of the Alaska Administrative Code unless the Commission specifically
authorizes a variance. Failure to comply with an applicable provision of AS 31.05,
Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or
the terms and conditions of this permit may result in the revocation or suspension
of the permit. When providing notice for a representative of the Commission to
witness any required test, contact the Commission's petroleum field inspector at
(907) 659-3607 (pager).

Formation pressures from surface to the Ma are calculated based on a .455 water gradient. Formation
pressures from the UG_Ma down to the SB_OA are based on W-200P61 RFT pressures taken before start
of W Pad Schrader Bluff production. Formation pressures in the SB_OBa through SB_OBd sands are
estimated and assume these sands will show moderate pressure depletion resulting from W-200 and W-201
Wellbore TD Criteria:
TD for all laterals is planned to be at end of polygon. No rathole is necessary.
No extensions beyond the end of the polygons are planned, however if extended poor rock quality is encountered
while drilling, some laterals could be ended sooner.
If structure along the laterals comes in substantially deep to prognosis, then the OBa lateral may be ended sooner
than the polygon end to avoid approaching any closer than 1500 feet to the minimum case OWC location. If O
sand structure comes in shallow to prognosis, the OBa lateral should be terminated at the point where the top OBa
marker depth is projected to reach a depth of -4970 feet TVDSS. Terminating the OBa lateral at this depth will still
leave a minimum of 1500 feet of lateral standoff to the minimum case OWC depth at -5030 feet TVDSS. O sand
structural depths along the W-204 laterals should be well established by the time the OBd lateral is drilled. Thus,
there should be between 5 and 10 days of time prior to drilling the OBa lateral to reconfigure the OBa lateral
profile, if necessary.

Surface and Anti-Collision Issues
Surface Shut-in Wells:
W-201 will require surface shut-in and well house removal in order to move over well W-204. No other wells
should require well house removal and surface shut-in.
Close Approach Shut-in Wells: All wells pass BP's major risk Anti-collision criteria scan. There are no wells that
will require subsurface isolation for this profile.

Centralizer Recommendations

a) Run (25) 10-3/4" Bow-spring centralizers attached over the collar of each joint of casing from the
casing shoe up to 1,000' MD above the shoe.
7-6/e" Casing Space Out
a) Spaceout the 7-°/s" casing to place a full joint in the window area of the OBb, OBa and OA sands.
b) Place 1 RA tag above each window exit. RA tags to be spaced out -40 - 80' above window

above the casing shoe.
Well Control
Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind/shear rams, and annular
preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon
calculations below, BOP equipment will be tested to 3,500 psi.
BOP regular test frequency will be 14 days, with a function test every 7 days.

Drilling Hazards and Contingencies
POST THIS NOTICE IN THE DOGHOUSE
I. Well Control
A. The Schrader in the target fault block is expected to be normal pressured at 8.2-8.7 ppg EMW. This
pressure is estimated based on offset well pressures and material balance.
II. Hydrates and Shallow gas
A. Gas Hydrates are possible at W-pad from the SV5 thru the SV1 sands below the base of the permafrost.
Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole
although there are previous instances of gas from the SV1 into the Ugnu on W-pad. Recommended
practices and precautions for drilling hydrates should be followed in the surface and intermediate hole
sections.
III. Fault Crossing/Lost Circulation/Breathing
A. Lost circulation is not expected on this well.
B. Fault #1, if detected, should be crossed in the SV3 formation, but should have a minimal throw at that
depth.
C. If the seismic artifact around the possible fault #2 locations does indeed turn out to be a fault then the well
bore will be sidetracked to a new BHL to the East. This new location will likely be over 500' away from our
current target and will require state approval before proceeding.
D. Breathing is not expected on this well.
E. 53 bbls with a 10.8 ppg EMW LOT, 9.2ppg mud and 8.7 ppg OBd EMW
F. Wood and associated running gravels have been caused problems on previous W-pad well surface holes.

followed at all times.
VI. Faults
A. Two faults could be crossed while drilling W-204. No losses are expected to be associated with these
faults.
B. Fault #1 -Fault is dying in throw upward. At intersection point with W-204, fault should have minimal
throw.
C. Fault #2 is a possible fault - if encountered, wellbore will be re-oriented to a more easterly postion.
D. Fault #3 will not be crossed by W-204. Fault position and standoff defines western side of target polygon.
