Abstract

Summary

Fracture-induced anisotropy is of moderate to large magnitude in sand reservoirs and can be examined in order to further advance our knowledge of fractures in the reservoirs. Production and increasing recovery rate of the existing oil and gas fields have shown to attract arrested attention and new emphasis. Fractured reservoirs contain an enormous amount of oil and natural gas. Fractures control in situ permeability; fluid storage and mobility; and rock strength; and thus the reservoir itself. Therefore, a clear insight into the subsurface fracture network will definitely promote optimization of well planning and production. Rock properties in a fractured reservoir indicate the amount of hydrocarbons and the convenience or inconvenience of production. Ignoring open fractures may lead to fluid flux, loss of circulation and other unsuccessful exploration and production efforts.
