Hydraulic Fracturing Isolation Methods and Well Casing Plugs for Re-fracturing Horizontal Multizone Wellbores |
| abstract |
A method for hydraulically isolating a portion of a multizone wellbore by providing a plug proximate the portion of the wellbore. The plug may be a proppant combined with a polymer. The proppant may be an ultra-lightweight proppant and the polymer may be cross-linked. The polymer may be a superabsorbent polymer or a hydrophobically modified polysaccharide. The plug may be formed by placing a pill of proppant and polymer within the wellbore and slowing pumping fluid down to cause the pill to bridge off and form a plug. The pill may also include a lightweight filler. The plug may be used to hydraulically isolate a portion of the wellbore during a fracturing or re-fracturing process. Multiple plugs may be placed along the wellbore to hydraulically isolate portions of the wellbore during the fracturing or re-fracturing process. |
