Abstract

Anisotropy is defined as the variation of the properties of a medium in different di- rections. The accurate determination of ANISOTROPY is very important in exploration geophysics studies, reservoir geophysics, the detection of appropriate drilling di- rection and the prevention of sand problems .The OSI tools measure shear waves slowness in two directions perpendicular to each other and parallel to the well axis. Anisotropic zones and the maximum in situ stress can be determined by using OSI log and mathematical method of ALFORD Rotation. The large difference between the maximum and minimum values, especially when the minimum energy is low, shows zones with significant ANISOTROPY. In this study, the ANISOTROPY of a carbonate reservoir was studied and the maximum in situ stress was determined. In the inter- val discussed, isotropic and anisotropic zones were separated. The maximum in situ stress from OSI has been determined to N30E direction, which is in agreement with the direction resulted from FMI (N19E) and the maximum stress in Zagros.
