Hourly activities:
00:00 - 01:15: Pumped 4,5bar/500 LPM, 4,5bar/1000 LPM, 12bar/1500 LPM, 26bar/2000 LPM. Tool failed to operate. Repeated pressure sequences a second time with no success. Made two pressure cycles with 26 bar/2000 LPM and 40bar/2500 LPM. Tool failed to operate.
01:15 - 02:00: Decided to change to back-up tool. Changed out primary to back-up multi cycle bypass valve.
02:00 - 03:30: Pumped 4,5bar/1000 LPM, 20bar/2500 LPM. Tool failed to operate. Repeated pressure sequences a several times with no success.
03:30 - 04:15: Ran in hole to 205,5m with multi cycle bypass tool
04:15 - 05:30: Attempted to cycle multi cycle tool with 18 bar/2500 LPM. No go. Repeated cycles with 1 min intervals between dipping pumps rather than 3 min. Observed bar pressure spike every 3 RD cycle, but tool is not closing/activating.
05:30 - 06:00: Discussed options with town. Carried out house keeping and PM projects.
06:00 - 07:00: Discussed multi cycle by-pass valve operational problems with service companies and town.
07:00 - 12:30: Attempted several times to cycle MCBV. Pulled out of hole from 207 m to surface. Broke out and laid out MCBV. Simultaneously had discussion and meeting with town regarding modified procedure and BHA configuration. Decided to take out MCBV and orient whipstock with gyro on wireline.
12:30 - 12:45: Tool box talk with crew prior to making up whipstock assembly
12:45 - 18:15: Picked up and made up 13-3/8" trackmaster whipstock assembly with 12-1/4" mill BHA. Surface to 266 m. Verified UBHO toolface offset and whipstock scribe lines.
18:15 - 19:30: Ran in hole with whipstock assembly from 266 m to final setting depth 432 m. Took 2 ton weight at 274 m but dropping off.
19:30 - 19:45: Held tool box talk with crew prior to rigging up wireline.
19:45 - 20:45: Rigged up wireline sheaves and picked up gyro tool. Ran in hole with gyro to 402 m sub). Found tool face orientation to be 178 deg. Rotated string to 190 deg. Confirmed by gyro.
20:45 - 21:30: Pulled out with wireline and confirmed tell tale OK on gyro. Moved string up/down twice to work out torque. Up/down weight 108/104 ton.
21:30 - 23:00: Ran in hole with gyro on wireline to 402m. Found tool face to be 187 deg. 190 deg 5 deg). Pulled out wireline and gyro.
23:00 - 23:45: On final position screwed in with TDS. Pressured up the string to 253 bar/10 min to set the whipstock slips. Observe hook load decrease from 106 t to 99 t. Proper setting confirm by setting down 10 t and applying over pull 10 ton. Pulled 140 ton ton overpull) to shear bolt for 12-1/4" fasttrack mill. Confirmed mill to be free.
23:45 - 00:00: Laid out 2 ea 3 m pup joints and made up one stand to string midnight depth 416 m.

24-hour summary: Due to operational problems with multicycle by-pass valve held meeting with service contractors and town to agree on a modified whipstock BHA and setting procedure. Made up and ran in hole trackmaster whipstock and 12-1/4" mill BHA to final setting depth 432 m. Made two wireline/gyro runs and confirmed final toolface to be 187 deg after having worked torque out of the string. Pressured string up to 253 bar/10 min to set the whipstock slips, confirmed correct setting and sheared bolt for 12-1/4" fasttrack tri mill with 32 ton over pull. Milled 12-1/4" sidetrack window from 421,5 m to 424 m. Note bottom window will be 428,2 m.
