AbrasiFRAC Abrasive Perforating and Fracturing
The AbrasiFRAC service perforates and stimulates multiple intervals in the well in a single field operation, offering better access in less time. The technique enables accurate placement of reservoir treatments down the CT-casing annulus. It permits the pressure required to initiate the fracture to be significantly reduced.
Slurry containing abrasive solids is pumped at high differential pressures through a specially designed jet gun conveyed on a CT workstring. The resulting high-velocity fluid stream can perforate tubulars (casing, liner, predrilled/slotted liner, and tubing) and any surrounding cement, then penetrate deep into the formation. Even in harsh environments, the jet guns will perform efficiently for several hours under downhole conditions.
For multiple-stage treatments, sand plugs or bridge plugs can be used for zonal isolation between the reservoir treatment stages. With the use of a retrievable or millable bridge plug, the AbrasiFRAC service can isolate, perforate, and fracture multiple zones in a single field operation. Jetting guns are available in various sizes and phasing configurations.
