Precision Stimulation Tool

PRECISION PRODUCT PLACEMENT

The Precision Stimulation Tool (PST) is a straddle packer tool that utilizes upper and lower packer elements to isolate intervals, and selectively inject acid or other treatments, throughout the wellbore. During operation, the packer elements are set independently to ensure 100% zonal isolation and enable optimized treatment pressure while inhibiting fluid leak off.

SINGLE TRIP SUCCESS

Cup isolation technologies risk damage while tripping within scale and debris laden wellbores. In contrast, the PST packer elements, when unset, have no contact with the casing thereby prolonging the life of the tool and mitigating wear. Operators can deliver several treatments (50+) in a single run without having to trip to surface to replace damaged cups, preventing non-productive time (NPT).

NO BARRELS LEFT BEHIND

On a single assembly, the PST combined with the industry proven Sandhawk BHA enables operators to locate, open and close Kobold’s Sandport sleeves to perform pressure tests and treat anywhere in the casing string. The PST is also fully compatible with perforated casing, milled out ball drop completions, and competitors’ CT shifted sleeves.

The Precision Stimulation Tool achieved a 99.33% isolation and treat success rate over field trials
