SUMMARY SIDE-TRACK PROCEDURES Pre-Rig Work: See Wellbore Diagram, 4 W' Tubing Must be cut below 8900' for side-track(Kick- off-point, KOP) operations. * Notify the field AOGCC representative with intent to plug and abandon* 1. "S" MIRU Slickline. Drift/tag liner top packer tailpipe SN "XN" @ 10524" MD. Note collapsed 5 Y2" liner @ 11,960' MD. 2. "O" Load and Kill IA and tubing. Perform injectivity test to verify ability to pump into the well. 3. "O" Plug & abandon w/15.8 ppg Class G cement. Overdisplace to perfs with seawater and diesel for freeze protect. Place 5 bbls minimum behind pipe into perf's. 4. "O" Max TOC is @ 8900' to allow tubing to be cut and sidetrack operations to be conducted. Minimum TOC is 100' above top perforation. "S" Drift/Tag Top of Cement, TOC, test, and document TOC per AOGCC requirements. "C" If TOC is higher than KOP, MIRU coil unit with 4.5" mill to clean up cement stringers. Re-test cement plug and record on chart. "O" Test the 7 5/8" casing annulus to 3500 psi against the packer. Hold 1000 psi on the tubing to prevent from collapsing the tubing. "E" MIRU E/L unit. RIH with jet cutter and sever tubing at or below anticipated side-track depth. A 7 5/8" ClBP & whip-stock will be set after the drilling rig removes production tubing. Jet cutter is acceptable as this tubing will not be fished. Note the depths of the GLM's in the tbg string. Circulate clean seawater around IA and tubing. "O" Test the FMC 7 5/8" mandrel pack-off to 5000 psi and service lock down studs by backing out and re-torquing one at a time. Test the tubing hanger pack-off to 5000 psi and service each LDS "O" Check with the Drilling Rig Supervisor regarding rig timing and determine if freeze protection to diesel will be required. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 3500 psi. Secure well with 0 psi on tubing and annulus "O" Remove the well house and flow lines. Level the pad and dig out the cellar.

Saw 200 lb weight drop, so decided not to investigate further. No problems getting through SABL-3 packer or milled out X nipple. CT PUH has 2k of pull at all depths in this liner. This is due to geometry. 5 bbls of cement mixed. 68cc FL, TT 1hr surface plus 5 hours, 46 minutes at 170deg. Circulate 1.5 well volumes to cool down. Laid 2.6 bbls in well via flexible hose from BJ unit. Well pressure steady at 500 psi. Ramped to 1500 psi. Inner annulus in direct communication so squeeze was spongy and had to build it at 1.9BPM to 1500 psi. Shut down pumps and pressure held steady for 10 minutes. Reversed out to 12500' CTMD. Made jet pass down from 12000' to 12500' and then back up to 12000'. Final reverse out to hard tag at 12500'. Cement has set up early due to insufficient well cooling (expected).
