Attachments it Duplicate 0) Oil Search Pikka C ST1 Sundry Application Requirement 1. Affidavit of Notice — Attachment A 2. Plat showing well location, as well as % mile radius around well with all well penetrations, fractures, and faults within that radius —Attachments B, E, and F 3. Identification of freshwater aquifers within''/: mile radius—There are no known underground sources of drinking water within a one-half mile radius of the current proposed well bore trajectory for Pikka C and Pikka C ST1. At the Pikka C location, the Permafrost interval extends down to approximately 1000-1200ft and therefore, no shallow aquifers (typically found down to 400ft depth) are located at the Pikka C location. 4. Plan for freshwater sampling — There are no known freshwater wells proximal to the proposed operations, therefore no water sampling is planned. 5. Detailed casing and cementing information —Attachment C 6. Assessment of casing and cementing operations —Assessment of casing and cementing operations will be performed after cementing operations are complete. 7. Casing and tubing pressure test information — Pressure testing will be performed upon completion of the well's lateral section. 8. Pressure ratings for wellbore, wellhead, BOPE and treating head —Attachment D 9. a -d Lithological and geological descriptions of each zone — e. Estimated fracture pressure for each zone listed below: 10. Mechanical condition of wells transecting the confining zones —As noted in Attachment B, the Qugruk 7 (PTD 213-204) well is within 0.5 -mile radius of the Pikka C ST1 wellbore. However, this well is currently plugged & abandoned. No public data is available as this is an exploratory well. 11. Location of faults and fractures in wellbore % mile radius — Based on the seismic and well data covering the Pikka C location, there are no known faults or fracture zones interpreted to be located within a half mile radius of the Pikka C and Pikka C ST1 wellbore trajectories. Seismic interpretation of the Nanushuk 3 reservoir and internal interpretation surfaces has determined that there are no faults of seismic resolution within the half mile radius (Attachment E). Furthermore, the use of seismic attribute analysis supports the structural interpretation. The coherency attribute which identifies structural fabric that is associated with faults and fractures suggests that there are no faults located within a half mile radius of the Pikka C and Pikka C ST1 wellbore trajectories (Attachment F). Oil Search does not expect that any hydraulic fractures during the stimulation of Pikka C STI will intersect any faults near the wellbore. If there are indications that a fracture has intersected a fault during fracturing operations, Oil Search will flush and terminate the stage immediately. 12. Detailed proposed fracturing program —Attachments G & H Pump Held IA Trip Pressure IA PRV GORV Pressure (psi) si (psi) (psi) Stages 1- 6 2500 2750 5000 4500 10. Mechanical condition of wells transecting the confining zones —As noted in Attachment B, the Qugruk 7 (PTD 213-204) well is within 0.5 -mile radius of the Pikka C ST1 wellbore. However, this well is currently plugged & abandoned. No public data is available as this is an exploratory well. 11. Location of faults and fractures in wellbore % mile radius — Based on the seismic and well data covering the Pikka C location, there are no known faults or fracture zones interpreted to be located within a half mile radius of the Pikka C and Pikka C ST1 wellbore trajectories. Seismic interpretation of the Nanushuk 3 reservoir and internal interpretation surfaces has determined that there are no faults of seismic resolution within the half mile radius (Attachment E).

If there are indications that a fracture has intersected a fault during fracturing operations, Oil Search will flush and terminate the stage immediately. 12. Detailed proposed fracturing program —Attachments G & H 13. Flowback procedure—Attachment I Section (b) — We will not be treating through production or intermediate casing strings.
