Proppex™ Frac Sleeves
This proppant exclusion sleeve, which currently is being developed for conventional reservoirs in the international market, prevents sand from flowing into the wellbore after the stimulation resulting from the fracture. Normal, pin- point fracture operations are performed with this technology. However, as soon as the simulation operations are completed, the sleeve is shifted into a “screen” mode in which a screen is pulled across the frac ports. The inflow of sand from the production operations is prevented from entering the wellbore.
