Case Studies
RETINA Stimulation™
The three aforementioned stimulation methods, namely, "dynamic underbalance" , "propellant gas fracturing” and "hydraulic fracturing” are evaluated in a case study to determine the most efficient method for a well drilled in a carbonate reservoir. The well has been perforated by a 3-3/8 inch, 22.5 HMX SDP gun with phasing of 60 degrees and shot density of 6 shot/ft. The productivity and skin reports have been presented here for all the methods:
| Method | Skin Factor | Productivity Ratio | Comment |
|---|---|---|---|
| Conventional Perforation | 11.00 | 0.42 | - |
| Dynamic Underbalance Perforation | 6.06 | 0.57 | DUP Ratio: 0.3 |
| Propellant Gas Fracturing | 4.46 | 0.65 | Propellant Loading Ratio: 0.25 |
| Hydraulic Fracturing | -3.68 | 1.84 | Pump Power: 2500 hp |
