The existing parent well is R-21. After we set the whipstock to sidetrack, there will be ~0' of parent welt perforations above the whipstock. We plan to set the whipstock., P&A the parent wall with cement, then wash cement out down to the whipstock. The perf©rations above the whipstock will be exposed to cement, and possibly P&A'd. After drilling a sidetrack, the new lateral will be completed with slotted liner. !t is possbfe that if the cement in the parent well perforations breaks down they could flow, along with the new sidetrack lateral, My question for y©u is "Should the Sidetrack be called the R-29A lateral because the parent well perforations have been P&A'd, or should it be called the R-21 L 1 lateral because the P&A might not be effective, car could break down with time?" Let me know what you think.

Prudhoe Bay R-21 L1, L1-01 CTD Sidetrack March 3, 2009 Permit to Drill approval is requested to drill two coiled tubing sidetracks from well R-21 starting on May 15, 2009. R-21 was originally a Z4 Ivishak well that is currently a long term shut in for low oil production. This PTD request is needed in order to relocate the bottom hole location into 2 different parts of the Sag River Sand. R-21 has a long production history with declining production since it was originally put on production in 1983. The water cut has been steadily increasing. Cement squeezes have been attempted to shut off water production with little success. The last well test in November of 2005 resulted in 28 bopd along with 6500 bwpd. There are little remaining production opportunities for the existing Z4 Ivishak perforations in the parent well, and the well has been shut in since 2005. The sidetrack plan calls for a workover to change the production tubing from 5-1/2" L-80 to 4-1/2" 13Cr80. This will be followed by a partial abandonment of the perforations in the parent well below the whipstock depth of 10,200'. Parent well perforations above ~n ~nn° will be preserved. Following the P&A, 2 big hole sidetrack laterals will be drilled and completed with a slotted - finer in a ag River sand.

Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind 8~ Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 3.75"x4-1/8" (bi-center bits used) Casing Program: Slotted Liner on both laterals R-21 L1 Lateral -~ • 2-7/8", L-80 6.16# STL Slotted Liner 10,400' and -12,542' and R-21L1-01 Lateral • 3-1/2", 13Cr80 9.3# STL Solid Liner 9,700' and - 10,190' and • 2-7/8", L-80 6.16# STL Slotted Liner 10,190' and -12,050' and • The second lateral drilled, the R-21 L1-01 lateral, will be completed with slotted 2-7/8" liner in the open hole section and solid 3-1/2" liner in the 7" interval to maximize production hydraulics and minimize the well slugging during production. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plans. There are 2 directional plans attached. One for R-21 L1 which is the eastern lateral, and one for the R-21 L1-01 sidetrack which is the western/southern lateral. ~--~ • Max. planned hole angle in R-21 L1 is 120 deg @ 10,412'. • Max. planned hole angle in R-21 L1-01 is 114 deg @ 10,490'. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property -12,145 ft. • Distance to nearest well within pool - 640 ft. (R-31 at the top of the Sag River) togging • MWD directional, Gamma Ray, Resistivity will be run over all of the open hole section. • Cased hole logs will not be run. Hazards • The maximum recorded H2S level on R Pad is 2200 ppm on well R-19 on 8/21/1996. • The maximum recorded ~ level on R-21 was 85 ppm on 10/28/200 • Lost circulation risk is low. • There is one significant close approach for these 2 sidetrack laterals; o R-21 L1 fails against R-09A. The 2 wellbores cross at 11,902' in the R-21 L1 lateral. The crossing occurs with a separation of 190'. R-09A is completed in the Ivishak. and R- ----~' 21 L1 is in the Sag River sand at that crossing o~ For these reasons, the hazard of a wellbore intersection is low. Reservoir Pressure • The max reservoir pressure was measured at 3,204 psi at 8800'ss on 6-22-2005. (7.0 ppg EMW). • Max. surface pressure with gas (0.10 psi/ft) to surface is 2,324 psi.
