FIELD: physics.
SUBSTANCE: methods and systems for gathering, deriving and displaying the azimuthal brittleness index of a borehole are disclosed. Certain embodiments include various methods for calculating and displaying borehole measurements in real-time for geosteering and drilling operations. One embodiment of the disclosed method for calculating and displaying azimuthal brittleness includes a step of taking measurements of compressional and shear wave velocities as a function of position and orientation from inside the borehole. These velocity measurements are taken by an azimuthal acoustic device. Azimuthal brittleness is then derived based on the compressional and shear wave velocities.
EFFECT: high reliability of data of planning geological survey operations.
