Drilling Advantages Wei-1 vs Kawa-1
Wei-1 shallow sections maintain similar design &
operational procedures as Kawa
Increased base case casing design; adding 16" liner at
Wei equivalent to Kawa's 13-5/8" casing
Achieve Kawa-1 equivalent of 11-3/4" liner with Wei-1
14" casing string - casing off Kawa-1 Campanian
challenging section and avoid slow deep underreaming
operations
2 contingency strings (11-7/8" and 9-5/8") available to
reach main objectives in last hole section
•
Drill out in 12-1/4" hole section to TD - 2500 feet:
Improves stable well bore conditions and logging options
No deep high pressure base case objectives – Coniacian
•
•
Operational Advantages:
Actual drilling data vs drilling model
Same rig and crews - with excellent basin experience
Continuity in well services
Continuity of highly experienced CGX drilling team
