Horizontal Wellbore Hydraulics Issues:
• Extensive data showing limited drainage performance in many horizontal well completions
• Often 30 to 70% of wellbore has never flowed oil or gas
Drainage Area
Frac Fluid / Drilling Mud
Horizontal Wellbore Hydraulics Issues:
Drainage Area
• Method Required to Increase Drainage Area:• Land pump in lateral section (?)

• Issues for landing pump in lateral section:• High gas rates “up stream” of the jet pump can cause flow interference
• Sweeping of fluid into casing & vertical
• Liquid hold-up & increased BHP
