摘要：

Fluid loss through natural fractures in oil reservoirs can be overcome using flow induced viscoelastic surfactant (FIVES) solutions. Single phase tests show higher flow resistance in fractures compared to matrix. This reduces the fluid lost through the fracture. During decane displacement, the amount of fluid lost through the fracture is lowered due to this increased local flow resistance. Improved recovery is obtained and the pore volume injected at break-through is reduced from 2.5 PV to ca. 1.0 PV. These results translate to a prolonged economic lifespan of a fractured heterogeneous reservoir and a significant reduction in post-processing costs.
