Abstract: A swage mount is provided for attaching a head suspension assembly to a head actuator arm for a hard disk drive. The swage mount has a flange body with a thickness for providing clearance from the underlying disk. The swage mount may have a tip for in-plane movement. The tip may be ‘T’ shaped. The tip has a thickness that is greater than the thickness of the flange body for withstanding out-of-plane loads and for enhancing performance of the hard disk drive, for example, during reading/writing of data using the head. Mass properties of the swage mount, the twisting/bending yield load, modal frequency responses, and other performance metrics are analyzed to design the dimensions of the swage mount having favorable in-plane compliance and superior out-of-plane robustness.

Abstract: Fracture- and stress-induced sonic anisotropy is distinguished using a combination of image and sonic logs. Borehole image and sonic logs are acquired via known techniques. Analysis of sonic data from monopole P- and S-waves, monopole Stoneley and cross-dipole shear sonic data in an anisotropic formation are used to estimate at least one compressional and two shear moduli, and the dipole fast shear direction. Fracture analysis of image logs enables determination of fracture types and geometrical properties. Geological and geomechanical analysis from image logs provide a priori discrimination of natural fractures and stress-induced fractures. A forward quantitative model of natural fracture- and stress-induced sonic anisotropy based on the knowledge of fracture properties interpreted from image logs allows the computation of the fast-shear azimuth and the difference in slowness between the fast- and slow-shear. The misfit between predicted and observed sonic measurements (i.e.

Abstract: A method of characterizing shear wave anisotropy in a formation includes obtaining crossed-dipole waveforms from a borehole penetrating the formation over a range of depths and frequencies, determining far-field slowness in a fast-shear and slow-shear direction using a low-frequency portion of the crossed-dipole waveforms, and determining near-wellbore slowness in the fast-shear and slow-shear directions using a high-frequency portion of the crossed-dipole waveforms. The method also includes marking a selected depth of the formation as having intrinsic anisotropy if at the selected depth the far-field slowness in the fast-shear direction is less than the far-field slowness in the slow-shear direction and the near-wellbore slowness in the fast-shear direction is less than the near-wellbore slowness in the slow-shear direction.
