Downhole fluid analysis (DFA) is a new, rapidly growing discipline in
wireline logging and has become a keystone in reservoir evaluation.
DFA addresses the twin failed and overly optimistic assumptions that oil
reservoirs consist of "one giant tank of one homogeneous hydrocarbon." DFA
naturally finds compositional gradients and identifies compartments by simple
new methods. Morevoer, DFA offers novel ways to establish reservoir
connectivity with new data streams not previously encountered in reservoir
reconnaissance.
Chapter 1, "The Distribution of Reservoir Fluids and Their
Characterization by DFA," describes the evolving symbiotic understanding of
reservoir complexities through DFA interpretation. DFA relies on bulk optical
spectroscopy, a technology not previously used in the upstream oil business.
Chapter 2, "The Photophysics of Reservoir Fluids: The Scientific Foundation of
Optical DFA Measurements," establishes in broad context the scientific validity
of DFA measurements.
