Reverse Hybrid • Initiate fracture with crosslinked fluid • 30% of job Volume • Low volume stages of small mesh high strength ceramic proppant • Maintain geometry with Slickwater • 40% of Job Volume • Pad/Prop/Sweep stages • High volume of water • High injection rate • Place proppant with Linear gel • 30% of Job Volume • Proppant ramp 1.5 – 2.0 ppg 40/70 mesh proppant • Proppant ramp 2.0 – 4.0 ppg 20/40 mesh proppant • Fracture initiation much less of a problem • Prop concentrations tend to be higher than Hybrid designs • Wellbore conductivity increased • Fluid volume less due to the crosslinked pad • Fluid requirements as low as 8,000 bbls per stage • High injection rates can be achieved
Typical Cotton Valley(Crosslink) • Fracture Initiation less of a problem due to crosslinked fluid throughout job • Highest propped concentrations achieved • Proppant stages ramped or stairstepped up to 5 ppg • Mesh size ramped up from 30/50 or 40/70 for 60-65% of schedule • Tail in with 20/40 proppant • Fluid volume requirement is diminished due to the crosslink fluid efficiency • Fluid volumes as low as 6,000 bbls • High injection rates can be achieved
