Mapping fracture corridors in naturally fractured reservoirs: an example from Middle East carbonates

摘要

In many oil and gas reservoirs, natural fracture networks help drain hydrocarbons and other fluids. The role of fractures is particularly important in reservoirs having a tight matrix. In carbonate formations, for example, it is quite common to observe a permeability contrast of 1000 or more between the rock matrix and surrounding fractures. Natural fractures are a recording of the reservoir stress history. They tend to be organized in different families oriented according to particular directions.
