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 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 remair, unchanged. The AP! number and in some instances the well name reflect the number of preexistin.( 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 ddii. The AP! number for this cancelled or expired permit is modified so the eleven and twelfth digits is 9[ The well name for a cancelled or expired permit is modified with an appended xx. These procedures are an addendum to the APl numbenng methods descnbed in AOGCC staff memoranctum "Multi-lateral (weiibore segment) Drilling Permit Procedures, revised December 29, 1995. AOGCC database has been changed to reflect these changes to this permit. Statistical Technician ~ALASKA~' rvices rilllng BP Exploration / Arco To: Alaska Oil & Gas Conservation Commission Date: March 6, 1996 From: Terrie Hubble Technical Assistant Permit #95-202, S-01B and Permit #95,203, S-01BL1 The regional structural high (targeted by the pilot hole) was confirmed. Due to the presence of 108 feet NLOC (net light oil column) versus the approximately 75 feet predicted, the decision was made to complete the pilot hole rather than risk costly plug backs and horizontal drilling. An Application for Sundry Approval was submitted and approved to complete the pilot hole (96-014). Consequently S-01BL1 was not drilled.

The permit to re-drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting re-drilling operations until all other required permitting determinations are made. The permit is for a new wellbore segment originating from well S-01B, Permit No. 95-202, APl No. 50-029-20717-02. Production should continue to be reported to the originating well identifier, 50-029-20717-02. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to ddlling a new hole. Notice may be given by contacting the Commission's petroleum field inspector on the North Slope pager at 659-3607.

As the S-lB annulus is not available for injection (cemented off), approval is hereby requested for annular injection into the following nearby wells (previously approved for injection by ADEC in 1990 and 1992, respectively).

There are no domestic or industrial use water wells located within one mile of the project area. The following design criteria were utilized in determination of maximum annular injection pressures (the attached pressure nomograph provides injection pressure vs. fluid density data): S-24 13-5/8", 68#, L-80 set and cemented at 2,668' MD (2,668' TVD) Burst (80%) = 2,760 psi 9-5/8", 47#, L-80 set and cemented at 9,843' MD Collapse (80%) = 3,800 psi S-33 10-3/4", 45.5#, NT-80 set and cemented at 2,958' MD (2,958' TVD) Burst (80%) = 2,864 psi 7-5/8", 29.7#, NT-95HS set and cemented at 9,018' MD Collapse (80%) = 4,096 psi A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 10/30/95 which demonstrates the confining layerS, porosity and permeability of the injection zone. The cement design for these wells (and the subject S-5A well) ensures that annular pumping into hydrocarbon zones will not occur. Worse case scenario calculations assume 17.0 ppg maximum fluid density and gas-filled inner casing (see attached nomograph for ppg equivalent mud weights vs. injection pressure profiles).
