IreM 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. IreM 4b: TPI (Top of Producing Interval). IreM 6: 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. IreM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). 1reM 20: True vertical thickness. IreM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Irene 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). IreM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). IreM 27: If no cores taken, indicate "None".

Drill approximately 1730' of horizontal sidetrack into Zone lA target with Resistivity logging to 12,130' MD. Bit selection size from 4.25" to 3.75". 5. Run 3-3/16" x 2-7/ '%,lid liner, TOL at 10,300' MD (8740'ss). ~' 6. Cement liner wi 23 is 15.8 ppg cement to place top of cement at TOL. 7. Cleanout liner an st to 2000 psi. 8. Log memory CNLIGR/CCL from the tubing tail to PBTD. 9. Perforate liner as per Asset instructions, approximately 1000' of perforations expected. 10. Freeze protect well and RDMO. Mud Program: • Well kill: 8.5 pp ruse • Milling/drilling:6 fpg Flo Pro or biozan for milling, new Flo Pro for drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Casing Program: • 3 3/16" x 2 7/8" fully cemented liner • A minimum of 23 bbls 15.8 ppg cement will be used for liner cementing.
