Evolution: Start
• Maersk: Dan Field, Denmark
– 14 Horizontal Wells and 126 Stages
(1989 – 1992)
– pletion time per stage = 85 hours
• Devon: First Horizontal t Shale Aug. 2002
SPE 19282
Evolution: 2010
• Multi-Stage Fracturing divided between
Open and Cased Hole
• Improvement in both Operational
Efficiencies and Cost Reduction
• Development driven by North American
Shale Plays
• Example: Bakken Formation . Sask
– Bi-lateral wells: 16 stages per leg
– pletion time
per stage = ~2 hours
