I. Plug and Perf
Perforate several clusters, isolate with drillable bridge plugs
II. Sliding Sleeves
Annular isolation using ECPs (ie: Swell Packers, etc)

Plug and Perf Method vs. PinPoint Stimulation
A typical Haynesville Plug and Perf frac:
5 clusters per 50m interval 5 shots per cluster 80bpm 19,600 HHP @ 10,000 psi Rate per perf: 3.2 BPM/perf 2 frac intervals per day
Pinpoint stimulation requires less equipment and a smaller footprint
A typical PinPointStimulation job with CTU:
1 cluster of perforations per job 3 hydrajetted perforations per interval 30bpm 6,250 HHP @ 8,500 psi Rate per perf: 10 BPM/perf Multiple intervals per day Aggressive frac designs
