A platform for research: civil engineering, architecture and urbanism
“Fracture Corridors” are swarms of fractures usually 10s to 100s of meters wide, often spaced at regular intervals with internal steeply dipping fractures. In addition, some corridors are related to faults of all types. As pointed out by Richard et al., tall fracture swarms are often the best‐connected fracture systems in a reservoir and, therefore, dominate fluid flow if encountered by the wells. Quantification of these swarms is very important in constructing a useful Static Conceptual Fracture Model. One of the most direct methods to determine the width of natural‐fracture corridors is by observations in horizontal wells. This can be accomplished with the observation of horizontal core taken over relatively small sections of the horizontal well, or with acquired borehole image logs and interpretations over longer portions of the well. This chapter shows how people can determine corridor widths in three horizontal wells in the Middle East.
