摘要:
Compositions, apparatuses and methods for isolating target zones for hydraulic fracturing, in particular, the use of smart fluids (i.e., magnetorheological fluids) to isolate target zones for fracturing by inducing an electromagnetic field to increase the viscosity of the fluids to form packers or plugs in the annulus of the wellbore and to isolate the target zone are disclosed.
