WebApr 10, 2024 · We assume that the borehole is inclined to the X-Y-Z far-field principal stress axes. The Cartesian coordinate system coincides with the principal axes of the in-situ far-field stress, which are designated as σ x, σ y, σ z. The borehole coordinate is defined by a local coordinate system x-y-z, with the borehole axes coinciding with the z-axis. WebJul 9, 2024 · Due to only one free surface underground.

Anisotropic Wellbore Stability Analysis: Impact on Failure

WebIn rotary drilling, the principal functions performed by the drilling fluid are to: 1. Carry cuttings from beneath the bit, transport them up the annulus, and permit their separation at the surface. 2. Cool and clean the bit. 3. Reduce friction between the drilling string and the sides of the hole. 4. WebIn an inclined configuration, the addition of fibers to hole-cleaning sweeps substantially improves cuttings removal, but only when the pipe is rotated. When the annulus is horizontal or the pipe is not rotated, addition of fiber has only a small effect on cuttings bed removal [ 29 ]. View chapter Purchase book Gaseated Fluids (Gas-Liquid Mixtures)
