Jaw-activated Frac Sleeve

The jaw-activated fracturing sleeve enables unlimited stage number in fracturing operations, in contrast to conventional ball-activated sleeves, the new design uses a retracted jaw and a ball to act as the ‘key’ to open the corresponding sleeve, the length of lugs on the jaw instead of ball seat ID could be used to identify different stages, thus the maximum stages is not limited to the tool ID and a larger wellbore is available for high rate sand slurry pumping.

A soluble ball could be used to ensure no restriction exists during production, no milling is required. The sliding sleeves could also be closed by intervention tools to adjust to the production results.

The activating force could be adjusted by replacing shear pins. Alloy steel is used by default and anti-corrosion materials could be selected as an option.
