Cancelled or Expired Permit Action
EXAMPLE' Point Mclntyre P2-36AXX AP1 # 029-22801-95
This memo will remain at the front of the subject well file.
Our adopted conventions for assigning AP! numbers, permit numbers and well names did not
specifically address expired or cancelled permits. This omission has caused some inconsistencies in
the treatment of these kinds of applications for permit to ddll. Operators have asked us to adopt
formal procedures for this class of permit application in order to prevent future database disparities.
If a permit expires or is cancelled by an operator, the permit number of the subject permit will remain
unchanged. The APl number and in some instances the well name reflect the number of preexisting
reddils and or muitilaterais in a well. In order to prevent confusing a cancelled or expired permit with
an active well or multilateral these case sensitive well identifiers will be changed for expired and
cancelled applications for permits to ddll.
The APl number for this cancelled or expired permit is modified so the eleven and twelfth digits is 95.
The well name for a cancelled or expired permit is modified with an appended xx.
These procedures are an addendum to the AP! numbering methods described in AOGCC staff
memorandum "Multi-lateral (weiibore segment) Drilling Permit Procedures, revised December 29,
1995.
AOGCC database has been changed to reflect these changes to this permit.

Subject: Cancellation of Approved Permits to Drill for Undrilled Wells
Dear Mr. McMains:
Per our discussion last week, I am writing to request that you cancel several
approved Permits to Drill for the Kupmmk River Unit. The wells wore permi~ for
different expansion and infill projects duzing the last two years. Due to information
gained from other new wells or to changes in the drilling schedule, the wells I'd like
to cancel were dropped from the program. While we will reuse the well names, by
the time the wells are actually ch-il]ed the information will be significantly different
than is on the current approved permits. Since this change requires re-submission of
a Form 401 anyway, I think it would be easier on both of us to cancel the current
permits. _
rd like m cancel the Permits to Drill for the following we!ls:
c~3- { ~ 8 KRU 2E-04
q~-- l']5 KRU2E-18
KRU ZA-18 (Permit ~93-166, issue date 11/9/93)

KKU 3M-27
KRU 3H-24
KRU 3H-29 '
KRU 3H-30
00<3
2A-18 and 2A-22 inadvertently have two Permits to Drill, each; please cancel only
the permit noted above.
Thank you for calling our attention to this matter. If you have any questions on the
above wells please call me,
Sincerely, " _ ,. , ,

Drilling fluid practices will be in accordance with the appropriate regulations stated in 20
AAC 25.O33.
Maximum anticipated surface pressure is calculated using a surface casing leak-off of 13.5
ppg EMW and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would
occur before a surface pressure of 1835 psi could be reached. Therefore, ARCO Alaska,
Inc. will test the BOP equipment to 3000 psi.
The nearest well to 3H-24 is 3H-16. As designed, the minimum distance between the two
wells would be 12.0' @ 200' MD.
Incidental fluids developed from drilling operations will be hauled to the nearest permitted
disposal well or will be pumped down the surface/production casing annulus of the last well
drilled. That annulus will be left with a non-freezing fluid during any extended shut down
(> 4hr) in pumping operations. The annulus will be sealed with 225 sx of cement followed
by arctic pack upon completion of fluid pumping.
*Spud mud should be adjusted to a FV between 50-80 sec/qt to drill gravel beds.

Dear Mr. McBride:
Enclosed is the approved application for permit to drill the above
referenced well.
The permit to drill does not exempt you from obtaining additional
permits required by law from other governmental agencies, and does not
authorize conducting drilling operations until all other required
permitting determinations are made.
Blowout prevention equipment (BOPE) must be tested in accordance with
20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE
test performed before drilling below the surface casing shoe must be
given so that a representative of the Commission may witness the test.
Notice may be given by contacting the Commission petroleum field
inspector on the North Slope pager at 659-3607.

Drilling fluid practices will be in accordance with the appropriate regulations stated in 20
AAC 25.O33.
Maximum anticipated surface pressure is calculated using a surface casing leak-off of 13.5
ppg EMW and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would
occur before a surface pressure of 1769 psi could be reached. Therefore, ARCO Alaska,
Inc. will test the BOP equipment to 3000 psi.
The nearest well to 3H-24 is 3H-16. As designed, the minimum distance between the two
wells would be 12.0' @ 200' MD.
Incidental fluids developed from drilling operations will be hauled to the nearest permitted
disposal well or will be pumped down the surface/production casing annulus of the last well
drilled. That annulus will be left with a non-freezing fluid during any extended shut down
(> 4hr) in pumping operations. The annulus will be sealed with 225 sx of cement followed
by arctic pack upon completion of fluid pumping.
*Spud mud should be adjusted to a FV between 50-80 sec/qt to drill gravel beds.
