Prior to drilling out of casing strings, test BOPS, and casing to the specified pressure listed in the BOP Program section. Plot test and record volume required on the drilling report. Leak -off tests (LOT) are to be conducted as described below: • Drill 20' to 25' of new formation below the casing shoe and condition the mud to the same properties in and out. • Pull drill bit into the casing shoe and close pipe ram preventer. Line up to the choke manifold with a closed choke. • Begin slowly pumping fluid down the drill string at 1/2 bpm while recording casing and drill pipe pressures at 1/2 bbl intervals. • A running plot of pressure versus volume should be kept by the Drill Site Manager while the test is in progress. • Stop pumping when the pressure curve departs form a straight line sufficiently to indicate leakage into the formation. Record as ppg equivalent mud density in the IADC and morning reports. • Monitor and plot pressure drop and time after shut-in for 10 minutes or until the shut-in pressure stabilizes. 7 Cook Inlet Energy Geologic Information • Surface Loc: X= 187750.768 Y= 2482269.659 • 2220' FSL & 1842' FWL Sec 16 T 8N R 14 W S.M. • Kickoff Point X=192382.95 Y=2488804.78 • 1700' FNL 1025' FWL Sec 10 T 8N R 14 W S.M. • Top Hemlock X = 192082.77 Y=2489354.66 • 1175' FNL 650' FWL Sec 10 T 8 N R 14 W S.M. • Bottom Hole Loc: X=191632.19 Y=2489711.05 • 800' FNL ' FNL & 250' FWL Sec 10 T 8N R14W S.M. • Kenai Peninsula Borough, Alaska • Ground Elev: 119.5 above MSL • KB Elevation: 26' above Ground Elevation • RKB: 145.5' above MSL Critical Formation T Formation MD TVD Potential Kick Off Point 12,071' 8,380' Hemlock 13,283' 9,370' Oil (Primary Objective) West Forelands 14,052' 10,085' Marker Total Depth 14,189' 10,125' 19, l $ �13 Permitted TD should be 1_4' MD. Actual Total depth may be shortened due to mechanical hole conditions, depth of intersection of Top Hemlock and dependent on shows observed within the West Foreland's formation. Note: The above tops are estimated from seismic and offset well control isopachs. Measured depths are estimated from directional plan WMRU-#8 ST dated August 29, 2014. These depths are not refined and may be slightly modified before spud. For planning purposes, they should be close. WMRU-08A Hazard Analysis H2S has not been an issue with any of the West McArthur River Unit wells drilled to date. WMRU-08A will be sidetracked at +/- 12,070'; therefore, there is not a potential hazard for shallow gas while drilling WMRU-08A. Mill window depth is also correlated below any potential zones with kick potential from the injection well. If there is an occurrence, normal drilling and tripping practices will mitigate any well control issues. There is potential for pack off and stuck pipe while drilling through the Hemlock and West Foreland coals. When transitioning to a coal, best drilling practices will be applied to mitigate risks and hazards. It is not expected that appreciable losses will occur based on offset well data. The nearest offsets (WMRU-8) were drilled with less than 10 ppg mud weights and there are normal pressures in other West Mac wells in the Cook Inlet. The MASP is based on a .44 psi/ft gradient or 8.46 ppg assuming this well has normal pressures. Higher mud weight, good drilling practices, and well control awareness will be utilized when transitioning from 8 i _ Cook Inlet Energy the Hemlock to the West Foreland. Mud loggers will continuously monitor DeXp. Upon each connection, a flow check will be made to insure that the well is static. The major hazards to drilling this well is mechanical issues related to drilling deep Tyonek, Hemlock, and West Foreland coals. Shallow Gas As stated above, shallow gas will not be a factor on WMRU-08A, as it will be sidetracked at +/- 12,070' with all zones above behind casing. Geologic Hazards No geopressures are expected to be encountered in this wellbore. Two nearby wells drilled the section with no abnormal pressures. Coals are expected to be the only hazards encountered. The pressured zone encountered in Well No. 8 that corresponded to the injection interval is a significant distance up hole and behind pipe.

A 1"=100' and 5"=100' MD and TVD log to be provided (No. of copies to be determined) after each run including both paper copies and digital data. Data in a .las format to be provided to Company man, Cook Inlet Energy Anchorage office, geologist, and State of Alaska AOGCC ASAP after logging concluded. Copy of signed transmittal form from AOGCC receipt of logs to be provided to Anchorage offices of Cook Inlet Energy. I Cook Inlet Energy Mud Logging Plan A two man mud logging crew should be on location and rigged up and logging from kickoff point estimated.to be at or near 12071' MD and logging as soon as practical following milling window for kickoff. A 2"-100' MD and TVD log to be provided twice daily no later than 4:00 am and 2:30 PM Alaska time. Logging unit should be equipped with hot wire and chromatograph equipment with 30' ditch samples being collected and sample descriptions prepared. Ten foot samples as needed, to be collected through potential pay zones. Two sets of dry cut samples are to be prepared and held until end of well. At the end of well one set is to be provided to State of Alaska AOGCC. Second set is to be provided to Cook Inlet Energy. Solids Control and Equipment Item Equipment Specifications Shakers Derrick Hy er ool Shakers Desander 3 cone desander Desilter 24 cone desilter Centrifuge TBA Drilling Waste Storage Drilling wastes will be either granular solids (cuttings), or liquids (drilling mud or water). Cuttings' and fluids will be disposed of in WMRU-D1 using the West MacArthur grind and inject facility. i Regulatory Waiver and Special Procedures Requests AOGCC Regulation 20 AAC 25.071 Geologic Information Not Applicable AOGCC Regulation 20 AAC 25.235 Gas Disposition CIE requests permission to vent or flare gas from the WMRU-08A well test for a period of 14 days according to 20 AAC 25.235 d (6). Maximum anticipated daily flaring is expected to be 10 MMSCF/D with a total expected not to exceed 20 MMSCF over the entire test. If the well is successful, it will be tied into the West McArthur production facility. AOGCC Regulation 20 AAC 25.265 Automatic shut-in equipment SSSV The WMRU-08A well has both an offshore BHL and a surface location within 660' of mean high tide, however, the expected bottom hole pressure and oil composition make it highly unlikely that 10 _ Cook Inlet Energy_ the well will flow to surface unassisted. CIE will install a jet pump completion and request a no flow certification under 20 AAC 25.265 (k) after stabilized flow is established. CIE Requests an extension of the time permitted to perform the no flow test from 5 days to 30 days after start of production. AOGCC Regulation 20 AAC 25.265 Automatic shut-in equipment SSV CIE requests permission to install the Surface Safety Valve in the WMRU-08A completion in accordance with the AOGCC approved Surface Safety Valve arrangement for the other West McArthur River Unit jet pump wells. The Surface Safety Valve will be located in the vertical run of the tree; however, the production will be taken out of the annulus. The power fluid will be automatically shut down whenever the Surface Safety Valve is closed.

The objective of the WMRU — 08A is to re-evaluate the Hemlock interval. In order to minimize the need of having large quantities of product on hand and also reduce the amount of cuttings that need to be hauled away, it is suggested that a highly inhibitive KLA-SHIELD system be used to drill the 6.125" sidetrack interval from 12,070' MD to 14,188' MD. The KLA-SHIELD system will be comprised of 4-6% KCL and sized Calcium Carbonate. Contingency products will be on hand to cover events such as mud weight increases and to combat any lost circulation problems that may occur.

Maintain mud weights as per program guidelines and or hole conditions and ensure that rheology is optimized to reduce ECD's to a manageable level while drilling. ■ Coal — In the Cook Inlet, area drilling through large coal seams have proven problematic in the past. Increasing the density of the drilling fluid has proven to be effective when any signs of hole instability due to coal are seen, Refer to the "Drilling Coal" section of the program. • Surge and Swab — Surge and Swab can increase the potential for wellbore instability, use proper drilling and tripping practices to mitigate this risk. ■ Logistics — Due to the limited amount of room for product and the effort it takes for the product to get to the drill rig, proactive measures need to be taken for logistics. Mud Engineers will take daily inventory and order product ahead of time. • pH — Keep pH in the range of 9.0-10.0 as this is essential in mitigating corrosion. ■ Tripping Pipe — Stage into the open hole in several increments breaking circulation each time and circulating for a period of time to ensure adequate fluid movement, Idle pumps when beginning circulation to minimize surge pressures. Work pipe and rotate while circulating to help break up gel strengths. Hole Cleaning Recommendations ■ Rheology and Hydraulics calculations will be run daily and the mud properties will be adjusted as needed to maximize hole cleaning. ■ Use the highest possible annular velocity to maintain good hole cleaning. Annular velocity provides the upward impact force necessary for good cuttings transport. ■ Control drill to manage difficult hole cleaning situations. Penetration rates determine the annular cuttings load. Use the PWD data (if available) to determine when it is necessary to stop drilling and circulate the hole. ■ Keep cuttings concentration less than 5% (by volume) in order to minimize drilling problems. • Virtual Hydraulics will be run through each hole section to optimize the fluid for maximun hole cleaning efficiency. Ver. 1.0 CONFIDENTIAL Page 3 of 14 M1 S1A/AC Cook Inlet Energy, LLC WMRU — 08A Sldetrack Fluids Program Sweep Recommendations • Don't recommend the use of sweeps unless hole conditions dictate. ■ Hi- Vis sweeps are recommended to use if needed. The volume should be enough to cover at least 200- 300 annular volume of the open hole. The recommended rheology of the sweep would have the Yield Point in the 35-40 range and the 6 RPM readings in the 15-20 range. • Weighted sweeps are another option, but Hi-Vis sweeps are preferred. ■ The need to pump LCM sweeps will be dictated by hole conditions. Bit/BHA Balling Recommendations • Reactive clay formations can absorb high volumes of water and can be extremely sticky and problematic regardless of the degree of inhibition. ■ The drilling rate should be controlled to keep the concentration of cuttings in the annulus below 5%. • Short trips should be made as necessary to minimize buildup of cuttings in areas of hole washout. • During trips, the BHA can accumulate cuttings that will potentially ball it. Recommend circulating for a short period to circulate up any formation that may have adhered to the BHA or bit during the trip.

Production Interval Overview The sidetrack interval will be drilled to a depth of 14,9188' MD using a 6.125" bit with the highly inhibitive KLA-SHIELD system at 9.5ppg containing 4-6% KCL. Wellbore stability is crucial to the interval as several coal seams will be drilled. A well maintained mud system supplemented with good solids control equipment for maximum solids removal will minimize fluid invasion. Proper drilling practices and properly engineered fluid will minimize wellbore instability. Any new fluid that is required should be built to the below specs.

Monitor for any fluid losses and flow back closely. • If additional mud weight increases are required outside of plan, control the ROP and flow rates as needed to avoid inducing a breakdown of any formations while drilling in the lower portion of this interval. Reduce pump rates immediately if packing off occurs. Run back to bottom and establish circulation. Pump high viscosity sweeps and ream carefully to clean the hole before proceeding with further drilling. • Adjust rheology, pipe rotation speed, pipe running speeds and pump rates as needed to balance hole cleaning and ECD. Use good drilling and tripping practices. Break circulation slowly — Reduce pump speed 15 to 20% while reaming down. Back reaming should not be utilized if possible to minimize the risk of coal seam instability. ■ Upon reaching casing point, watch the bottoms -up cuttings closely. If the well does not readily cleanup or if there are any excess of torque, drag, pick-up or slack -off weights pump a high viscosity /weighted sweep and observe bottoms up again. • Minimize dilution rates as much as possible by utilizing the rigs solids control equipment. Monitor screen condition closely. Ensure centrifuge is running properly and that all de-sander/de-silter cones are "Spraying" and not "Roping". Interval pore pressures may vary. Shale stability and pore pressures could require a higher or lower mud weight. Any fluid weight adjustments should be performed in 0.1 — 0.2 ppg increments using Safe Carb-40 as a weighted "spike" fluid. Production Interval Fluid Operations: ■ Ensure all MSDS sheets are available for the rig crews and have been reviewed. ■ Run corrosion ring in the drill string per M-1 SWACO's corrosion mitigation program. ■ When building the KLA-SHIELD drilling fluids system, follow the fluid recipe and make changes as necessary to target a yield point of 15-28 (lb/100ft2). ■ The initial makeup will consist of 1 ppb of RESINEX and 1 ppb SACK BLACK. This will be increased while drilling ahead for hole stability and fluid loss. ■ Use only Busan 1060 for bacteria control. DO NOT use Myacide GA25 (Glutaraldehyde). Ver. 1.0 CONFIDENTIAL Page 6 of 14 Mi SIIA/_ Cook Inlet Energy, LLC WMRU — 08A Sidetrack Fluids Program ■ Always be aware of the condition of the cuttings as they go over the shaker. If cuttings become soft or mushy, these are signs of insufficient inhibition. Test the KLA-STOP and KCI concentrations in the system and adjust accordingly. ■ Maintain 2% v/v KLA-STOP in the system; monitor the concentration using the titration method. Add additional KLA-STOP as needed to maintain the proper concentration needed for inhibition. ■ CONQOR 404 WH additions should be made daily when drilling with KLA-SHIELD drilling fluid system in order to prevent any oxygen corrosion. Maintain a CONQOR 404 WH concentration of +l- 2000 ppm or 0.15 gal/bbl, ■ Monitor the HTHP (@165°F) and keep below 8.0 cc/30 min (using paper). Also run a modified HTHP using a 5 micron alloxite disc, keeping fluid loss below 10.0 cc and spurt loss below 2.0 cc. ■ Maintain a low API fluid loss of < 5 ml/30 min. Make the necessary additions of RESINEX, Calcium Carbonate, SACK BLACK and POLYPAC SUPREME UL. ■ Keep MBT values below 10 ppb. ■ If any high torque is seen and suspected to be initiated from the formation, add LOTOTQ. Note — Be careful not to let addition of lubes mask hole cleaning problems. Also ensure that the amount being added complies with any compliance regulations. ■ If the mud weight needs to be increased past 11.5 ppg, barite sag could become an issue. (Barite sag is a reduction in the MW out due to the dynamic and static settling of barite) If the mud density is weighed up past 11.5 ppg, avoid low pump rates and low drill string rotation. Make sure and run the VSST barite sag test. • Upon reaching TD, watch the bottoms -up cuttings closely. If the well does not readily clean up after 3 — 4 bottoms up, or if there are any excess of torque, drag, pick-up or slack -off weights, pump a high viscosity / weighted sweep and observe bottoms up again. Continue pumping while rotating and reciprocating until the wellbore is clean. ■ Run casing to TD and do not alter the YP. After casing is landed, isolate on one pit and condition fluid in preparation for cementing per the cementing program with additions of water and CF Desco II. Be sure to isolate on one pit so only the necessary amount of fluid is being treated. ■ Keep track of water and whole mud additions and record daily in One-Trax. Ver. 1.0 CONFIDENTIAL Page 7 of 14 Cook Inlet Energy, LLC WMRU — 08A Sidetrack Fluids Program Drilling Coals: Introduction Coal is commonly encountered in gas -bearing Carboniferous. The associated drilling problems include tight hole, wash outs, stuck pipe, lost circulation, sloughing and pack off and gas influxes. Most of the problems occur when the coal is encountered at depth (i.e., is present as primarily anthracite rather than lignite). Coal formations have low density and are typically brittle, with low compressive strength, and often highly fractured. They can collapse into the borehole in areas of high tectonic stress resulting to stuck pipe. Other drilling problems in the Carboniferous include slow ROP, high torque, drag and BHA shock severity (especially if using water -based fluids) and stick -slip. These are due to the hard, abrasive nature of the sands. In some areas, both the inter- bedded shales and sands can be fractured, leading to lost circulation. Recommendations for Drilling Coal The use of Oil Based Mud (OBM) is generally preferred although water -based fluids have been used. In both cases the addition of wellbore plastering agents such as Gilsonite / Soltex/Asphasol Supreme/ Resinex is recommended. The fluid rheology should also be considered. It is essential to maintain adequate hole cleaning especially in high -angle wells. If the hole is not being properly cleaned, the larger coal particles may have a tendency to pack off. Coal has a low density (range 1.1-1.5 with pure anthracite = 1.5) and weighted sweeps may be very effective due to the buoyancy effect. Mud Weight Adequate mud weight should be maintained to ensure stability of the formation. The coals in the Cook Inlet area have a very `Plastic" characteristic and coal stability can be enhanced by increasing the drilling fluid weight. Care must be taken when using high mud weights to avoid exceeding the fracture gradient. Most importantly, good drilling practices should be employed together with the suggested drilling fluid solutions to achieve optimum results. The first sign of coal is normally a significant drilling break. If this occurs, the driller must pull off bottom with the pumps on and perform a flow check. Swab and surge pressures should be minimized as should the amount of time the drill string is kept static. Coal seams are notorious for washing out and this can lead to ledges developing. Care is required when tripping to avoid kicking off a new hole from the ledges. If a pack -off does occur, running back into the hole and circulating will normally clear it, Operations As with any unstable formation, it will be beneficial to minimize trips, reaming and back reaming if possible. Drilling with low WOB and high RPM and with the minimum number of stabilizers may help. Control the drilling rate to prevent overloading of the annulus if the coal is tending to break out. In extreme cases, it may be necessary to drill the coal seam in short intervals, reaming each new hole section before progressing. Experience shows that it is best to avoid sliding through coal seams and also best to maximize the angle at which the wellbore penetrates the coal seam. However the solubility of lignite is much reduced in saline fluids and no problems are seen in KCl/polymer of salt/polymer systems. Ver. 1.0 CONFIDENTIAL Page 8 of 14 Mi S%A 4A C Minimum Time to Circulate Prior To POOH Cook Inlet Energy, LLC WMRU — 08A Sldetrack Fluids Program This model simply predicts the minimum flow rate required for adequate cuttings transport. No predictions are available for the rate at which cuttings are removed. Because the cuttings move more slowly than the circulating mud, it is essential that sufficient bottoms -up are circulated prior to tripping. A SINGLE BOTTOMS -UP IS NEVER ENOUGH! The minimum on bottom circulation time prior to tripping will be influenced by hole size, inclination and flow history (i.e. mud properties and flow rate). These factors will affect the height of any residual cuttings beds. Recent work by Exxon has indicated that the volume of cuttings left behind during normal drilling operations can be considerable. They recommend selection of bits/BHAs with large bypass areas to facilitate tripping out of the hole. Before tripping, monitor the shakers to ensure the cuttings return rate is reduced to an acceptable background level. The figures in the table below are guidelines based on simple slip velocity considerations and field experience: WELL INCLINATION RANGE SECTION LENGTH FACTOR 17.1/2 inch HOLE 12-1/4 inch HOLE 8.1/2 inch HOLE 00 -100 1.5 1.3 1.3 100 - 300 1.7 1.4 1.4 300 - 600 2.5 1.8 1.6 600 + 3.0 2.0 1.7 Procedure 1. Effective length = Section length x section length factor. 2. Circulation time = E Effective Length x B/U Measured depth at Bit Example Since in practice not all of the section back to surface will be deviated at the same angle, the overall minimum circulation time prior to tripping should be apportioned in direct relation to the relative lengths of section at each angle.

Recommended shaker screens sizes are as follows: Interval I Recommended Screen Sizes 12,070'-14,188' (Production) 1200 — 230 mesh ■ Run all solids control equipment when drilling ahead. ■ Monitor LGS and sand content closely. ■ Screen up as much as possible. • Monitor screens for holes and wear. Replace screens if holes occur. Lost Circulation / Seepage Action plan • Have sufficient sized LCM on rig to begin loss interval. It takes 40 ppb of sized calcium carbonate to make a filter cake with this plugging material. Use in combination with 5 ppb SACK BLACK and MIX II at 5 ppb. • Recommend hourly addition of LCM to keep a concentration in the system at all times. The addition of SAFE-CARB (40,250,500), MIX II (cellulosic fiber), SACK BLACK (treated Gilsonite) and G-SEAL (sized graphite) can be adjusted as needed to combat losses. • The particle size of the LCM is important. If the expected loss zone particulars are known, then plan to have LCM to offer a particle size distribution so the majority of the LCM has a D50 to cover 1/3 the expected pore throat size and a D90 of cover the pore throat size. The D90 material should make up 10% of the total LCM ppb pumped. • Coordinate spotting and wait time for LCM pills if losses are over 60 bph. ■ The majority of losses can happen when running casing, circulating before cementing and while cementing which should be monitored closely. The use of Virtual Hydraulics Surge Calculations is recommended to establish safe casing running speeds. The use of open -float and M-1 SWACO WELL COMMANDER should be considered to help minimize surge pressures to formation. ■ OPTIBRIDGE Software will be run while on location to develop the specific particle size distribution for the LCM materials to be used for any formations with the known tendancies for lost circulation.

It is widely used as a weighting material in cement spacers and occasionally in cement slurries. It can yield a slurry density in excess of 19 Ibs/gal. C D-32 A patented, free -flowing, water soluble polymer that is an efficient and effective dispersant for primary and remedial cementing. Class G Cement Intended for use as a basic cement from surface to 8000 ft as manufactured, or can be used with accelerators and retarders to cover a wide range of well depths and temperatures. EC-1 A proprietary product that provides expansive properties and improves bonding at low to moderate temperatures. FL-62 A patented dry blend of water soluble polymers that are formulated to control the loss of fluid during cementing operations. A dispersant and bonding additive are proportioned to deliver consistent performance and control fluid loss in primary and squeeze cementing applications at low to moderate temperatures. FP-6L A clear liquid that decreases foaming in slurries during mixing. R-3 A low temperature retarder used in a wide range of slurry formulations to extend the slurry thickening time. SealBond Spacer (w/ 451b bag) SealBondTM spacer systems combines the unique quality of a cement spacer system with the added advantage of curing lost circulation and wellbore strengthening properties. The viscosity as well as lost circulation and strengthening properties can be adjusted using the SealBond 25, 50 and 100. In severe lost circulation cases Sodium Metasilicate An extender used to produce an economical, low density cement slurry. Static Free An anti -static additive used to prevent air entrainment due to agglomerated particles. Can be used in Cementing and Fracturing operations to aid in the flow of dry materials.
