The HDMAAL framework offers several benefits, including:
Standard sonic logs measure compressional and shear wave slowness (∆t) along the borehole axis, assuming a homogenous formation. However, in fractured, stressed, or anisotropic formations (e.g., shales, tight carbonates), acoustic properties vary significantly with direction. HDMA AL work addresses this limitation by employing multi-receiver arrays and azimuthal transmitters to map these directional variations. The “High Density” aspect refers to both the spatial sampling along the borehole and the dense azimuthal coverage (typically 12 to 16 sectors around the 360° circumference). the hdmaal work
Slow down. Make things. Be proud.
