“…Intrinsic anisotropy is derived primarily from the presence of shale, aligned fractures and/or thin bed layering; stress induced anisotropy comes from the application of unequal stresses around the borehole. Anisotropy alone is not enough to characterize the different dominant anisotropy mechanism in the rock, so we have to introduce dispersion analysis, which can help to identify natural fracture [4,5,6]. Environmental Protection and Resource Utilization IV There are four common dipole dispersion curve mechanisms.…”

Fracture effectiveness, extension and connectivity from borehole surface into deep formation are the key factors to control producibility of volcanic formations. A systematic and integrated fracture delineation approach was set up which integrated available measurements with multi-scale depth of investigation to cover borehole surface, near wellbore and deep formation. High resolution micro-resistivity image was used to identify fractures on the borehole surface; shear anisotropy enhanced by dispersion analysis was used to evaluate fractures away from the borehole; Borehole acoustic reflection survey technique was applied in vertical wells to assess probable fracture networks deep into formation up to maximal 10 meters. This multi-scale approach had been implemented in multiple wells drilled in volcanic formations in Junggar basin, which helped a lot on fracture evaluation and productivity estimation.
