DESCRIPTION:Understanding structure/transport relations for multiphase flu
 id flow in heterogeneous reservoir rocks is critical for improved recovery
  of petroleum resources. Nuclear magnetic resonance (NMR) provides a power
 ful toolbox for exploring hydrodynamics within opaque porous materials. In
  this presentation I will highlight various ways in which NMR has enabled 
 better understanding of complex fluid flows. Over the past few years we ha
 ve explored enhanced oil recovery mechanisms\, considering the displacemen
 t of trapped oil by surfactant or polymer solution injection. NMR has allo
 wed us to monitor the transport of microemulsion phases through a real roc
 k structure and observe the effect of elastic turbulence generated by flow
 ing viscoelastic polymer solutions on trapped oil ganglia. Case studies re
 veal the importance of these mechanisms in the oilfield context. Furthermo
 re\, I will introduce future directions for low-field bench-top NMR instru
 ments and discuss some of the open questions and challenges that we are ex
 ploring presently.\n
