Determine the In‐situ Stress Directions and Magnitudes and their Variation
The subsurface in‐situ stress state is an important aspect in understanding and quantifying fractured reservoirs as it directly impacts the behavior of a reservoir and its fractures prior to, and during, production. This chapter shows that the relative azimuth and magnitude of the principal in‐situ stress components and that of the dominant open‐fracture azimuth controls the distribution of fracture aperture azimuthally and, therefore, the resultant maximum permeability direction for creation of an Static Conceptual Fracture Model (SCFM). It illustrates an example of such modeling. In this figure, data of the interpreted stress variation across a portion of the Maracaibo Basin is compared with the azimuth of mapped faults in the reservoir on a grid‐square by grid‐square basis, and the resultant in‐situ stress component acting perpendicular to the fault trace resolved. Using a published algorithm from the North Sea, this was converted into fracture permeability for creating the SCFM.
