The well has undergone a rig work over completed July 12, 2015 to replace the tubing and repair inner by outer annulus pressure communication. A MIT-T& MIT-IA both passed to 3500 psi on July 11, 2015. The passing tests confirm two competent barriers in the wellbore. The well is reclassified as Operable and may be brought online. Please use caution when placing the well on production as the annuli are fluid packed. Please call with any questions or concerns.

From:Josh Tempel,ODE for 07-34B Subject:Verification of Cement on 7" casing cement job Purpose:This email describes the likelihood of good cement on the 07-34B Intermediate Cement Job. On 6/23/2015 Doyon 14 cemented a 7" intermediate casing string in 8-1/2" hole. Planned cement was 1500' MD/1404'TVD of coverage above the shoe.The shoe was placed 5' into DPZ3,9220' MD,which is called TSGR (Top of Sag River) in this well.The result of the cement job was that the plugs did not bump, but lift pressures show the full column of cement was lifted using 15%open hole excess, and the rig achieved a good casing test to 3500psi. Losses included 17.3bbls prior to cement rounding the corner and 24bbls more barrels after cement started rounding the corner.Total cement volume pumped was 47.2bbls. Losses most likely were mud and spacer with a small amount of cement, and the losses most likely went to a weak formation in the CM2"8030'MD which is 1190'MD/1106'TVD above TSGR. 1 • • During the cement job the rig used Schlumberger to displace the initial 308bbIs and the rig displaced the remaining 45bbls of the job. Early in the displacement Schlumberger saw cavitation from one of their two triplex pumps which resulted in the cementing crew continuing the displacement with a single pump. Further in the displacement,approximately when the bottom plug was supposed to land,the pressure spiked to 1430psi which triggered a pressure controlled shut off on the remaining pump.The WSL and ODE decided to use rig pumps to perform a casing pressure test to 3500psi to see if more pressure would cause the blockage to come free. (Schlumberger lines were only pressure tested to 3000psi). At 2325psi the bottom plug sheared and the rig was able to continue the displacement.The rig displaced 45bbls at max 4bpm.Although the plugs had not bumped,the ETL made the decision to not displace any more fluid.As per the stroke count the full shoe track had already been pumped; however, it is likely that between the cavitation issues in one Schlumberger pump and the change between Schlumberger pumps and rig pumps that some fluid was unaccounted for or stroke volumes were over calculated. When the 7" shoetrack was drilled uncontaminated solidified cement was found 5bbls high,an FIT of 10.7 was achieved,and no u-tubing was observed.A 10.7 FIT was planned as the maximum shoe strength needed to drill the production hole section. Most Likely Scenario The fluid lost during the cement job likely went to a formation called the CM2 with a base at 8030' MD. During drilling operations and during circulation at TD breathing was confirmed. Breathing is a common phenomenon in Prudhoe Bay and is attributed to the CM2. Breathing is not known to occur in any other formations that were drilled on 07-34B. Each time the formation was cycled and breathing occurred while drilling it seemed to start at a lower ECD. During circulation at TD fluid was pushed away starting a breathing event at pump rates greater than 5bpm.The Schlumberger displacement achieved 7bpm. Considering the extra formation cycling,the higher pressures on the formation from having 11ppg spacer above the CM2,and the added 2325psi pump pressure required to shear the bottom plug, it is highly likely the CM2 would take the full 24bbls of fluid during the rig's 45bbl displacement. Additionally, further evidence that losses were occurring above or near the top of the cement column is that the lift pressures achieved match likely lift pressures using 15%open hole excess. Worst Case Scenario The worst case scenario is if the 24bbls of losses went to DPZ3.This scenario results in a 485' MD/420' ND cement column at 15%open hole excess. In summary,the most likely case is that the 07-34B intermediate cement job achieved 1190'MD/1106' ND of cement column; however, even under the worst case scenario using 15%excess,485' MD/420' ND was achieved. Considering the most likely cement column and that the shoe also tested to 10.7ppg then, in my judgement as an engineer, I think good isolation was achieved.
