Energy IP offers a permanent method to plug perforations in a well prior to a mech-iso refracturing effort. Their patented process pumps an aqueous slurry of their SwellFrac material into perf tunnel where the particles can expand and form permanent, pressure-tolerant plugs to seal the perforation.

Product Overview
Overview
Energy IP markets SwellFrac, a surface pumped method to isolate perforations in completed wells with a swellable elastomer/cellulose fiber mixture that creates permanent, pressure-stable plugs to seal undesired perforation tunnels
Key Products
- SF NANO: The smallest of the elastomeric particles, ranging from a 100-mesh equivalent to 1mm diameters
- SF CORE: Elastomeric particles ranging from 2 to 6mm in diameter when fully expanded
- SF MAX: The largest elastomeric particle size, ranging from 6 to 10 mm in size when expanded
- SF REACTIVE FIBER: An extruded swellable fiber that is cut to different lengths and used to increase bridging behavior
All products are stable to 400 F and compatible with all common completion fluids, acid treatments, and in-situ corrosive elements
Business Model
SwellFrac is sold on a volumetric basis though Energy IP is open to other contractual arrangements including sales on a per well/per pad basis.
Technology Innovations
- Tolerant of high-temperature or corrosive downhole environments
- Will effectively seal irregularly shaped or eroded perforations, unlike typical ball sealer-style diverters
- Provides 10-20 years of perforation sealing unlike the temporary seal provided by most near wellbore diverters
Applications
Key areas for SwellFrac application include:
- Isolating perforations in a horizontal lateral prior to wellbore cleanup & refrac
- Sealing areas of casing leak/deformation when slurry injection is possible
- Permanent matrix shutoff of fractures responsible for significant water ingress
