ITEM 1a: 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 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".

E-37A Permit to Drill Version 1.0 Page 3 The proposed £-37 A well lies in a moderate risk province of the field for lost circulation at faults as documented by the WURO team and the risk of loss circulation events should be lower than average. Nine loss circulation events were encountered in the Ivishak section in 5 of the surrounding 30 wells as detailed below. No faults are expected to be encountered by the well. Additionally, loss circulation risk for any unmapped fault should be low if it is encountered in the low net/gross Zone 1 A section. A fault is present southeast of the planned well in the build section. The intermediate target (above the landing pt) is a hard point to maintain the wellbore 130 ft away from this fault. Six additional faults are present ranging from 130- 240 feet north and south of the planned well. The polygon lines are hardlines to the north and south but the well can be extended to the west up to 600 feet if necessary.

Issues and Potential Hazards ~ No wells will require shut-in for the rig move off E-37A. However, E-19 is about 35' to the North. There are no wells on the surface to the South of E-37. E-19 is the closest surface neighboring well. E-19 is a current producer and has been flowing intermittently for the last few months. Care should be taken while moving off the well. Spotters should be employed at all times. .:. There has been a small ice pad connected to the South side of E-pad to allow maneuverability for the truck spotting the pits. Spotters should be utilized while the truck is on this pad. ~ Note on Barriers during the ND BOP I NU Tree procedures: · Tubing - Kill weight fluid and a TWC. · IA - Kill weight fluid, tested annulus and annular valve. ,,/ · OA - Kill weight fluid, tested annulus and annular valve. ~ Note on Barriers during the RDMO procedures: · Tubing - Kill weight fluid and a BPV. · IA - Kill weight fluid, tested annulus and annular valve. / · OA - Kill weight fluid, tested annulus and annular valve.
