Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: 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 and Ground Level elevation in feet above mean sea level. 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: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: 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 27: Method of Operation: Flowing,Gas Lift, Rod Pump, Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain).

My engineering justification for not performing a new LOT is as follows: 1. Using the surface casing shoe LOT in a sidetrack correlates to the grassroots standard/regulation of drilling a well and using the surface shoe FIT/LOT.This is further correlated because there is no cement behind casing from the KOP to the surface casing shoe which would likely result in testing the integrity of over 4000'of formation. Performing a LOT at the KOP would be similar to performing a LOT part way through drilling the intermediate section of a grassroots well which is not the goal of a LOT. 2. The original surface casing LOT for R-08 is greater than the LOT requirements stated in the original PTD,and thus exceed the kick tolerance requirements to drill the intermediate section of this well. Thank you for your consideration.

Initial production rates from R-08 were about 5000 bopd and 0 %WC. It had a RWO in 1984 to install 5-1/2" tubing with gas lift mandrels. In November of 1985, perforations were added from 11222'MD— 11248' MD which brought in significant amounts of water. R-08 had an IBP set in 1988 @ 11,212' MD which successfully shut off the water production. A few months later, Sag perforations were added and the Sag was frac'd with little change in production rate. In 1991, the Sag was squeezed and R-08 had an Ivishak frac. This resulted in a small bump in oil rate, but then the oil quickly began to decline while water steadily rose. The Sag was re-perforated in December of 1992. R-08 consistently produced until 2006 when the well was SI for high watercut. In 2009 diagnostics found the IBP up hole which was determined to be the source of the water. Reason for P&A/RST: During screening for a coil sidetrack in 2012, the well was found to have TxIA communication. A LDL determined the source of leaks to be from GLM 2, 4, & 5, at the sliding sleeve, and at the packer. A RWO was deemed uneconomic at the current location, and the tubing condition made the well a poor candidate for a coil sidetrack. Due to low reserves in the current location and poor tubing condition, it was released for a rotary sidetrack.

R-08A PTD Page 6 11/25/2014 R-08A Drilling Critical Issues POST THIS NOTICE IN THE DOGHOUSE I. Well Control / Reservoir Pressures: A. Intermediate Hole: Sag River is expected to be an 5.1 ppg EMW. II. Lost Circulation A. The Sag River has a lower than average pore pressure and fracture gradient in this area of R-pad. Due to the lower frac gradient there is an increased risk of lost circulation during Drilling, Casing, and Cementing of the intermediate hole. B. Almost all Sag River wells have experienced lost circulation in the Production Hole section. Both faults to be crossed have had minor losses in offset crossings ranging from 30 bph to 5 bph. Ill. Faults A. Fault 1 will be crossed at 11,741' MD in the Ivishak Zone 4. It is estimated to be 20-40' down thrown to the north east. The offset well R-03B crossed it and had minor lost circulation of-30 bph B. Fault 2 will be crossed at -12,176' MD in the Ivishak Zone 4. It is estimated to be 70-90' down thrown to the South West. The offset well R-03B crossed it and had minor lost circulation of-30 bph IV.Integrity Testing Test Point Test Depth Test type EMW(lb/gal) 9-5/8— window 20'-50' from the 9-5/8" window LOT 12.6 ppg 7" shoe 20'-50' from the 7" shoe FIT 9.0 ppg minimum VI.

All HSE risks will be eliminated prior to drill by, and the wells will be minor risked to an appropriate value. CONSULT THE R PAD DATA SHEET AND THE WELL PLAN FOR ADDITIONAL INFORMATION.
