ABSTRACT:
A process to temporarily seal an upper zone of higher permeability. Coiled tubing is used to cover a zone of lower permeability with a gel block containing rock salt. A lower density, more stable, slower yielding gel block having a gel breaker is squeezed into the upper zone. The well is shut-in and the low density gel plug becomes rigid. Water is then circulated down the coiled tubing to dissolve the high density gel block out of the wellbore and re-open lower perforations which allows the low permeability interval to be treated.
