Title
Visualization of Geostress Tensor along Oil Well Trajectory
Abstract
Abstract: In this paper, a simple and efficient method is proposed to visualize symmetric second order tensor along 3-D curves. It is also applied to an oil well model in which along well trajectory the spatial distribution of geostress is visualized to predict the stability of oil wellbore. To give visual representations several forms are used: (1) with init-situs-stress picture we visually compare the magnitude of stresses to determine the mud-weight. (2) Based on a set of ellipse cross-sections along the well trajectory and the ellipticity of ellipse we predict the shear failure direction and the stability of oil wellbore. (3) From hinged curved surface, we emphasize the direction of principal stresses. (4) To give useful information we apply other skills such as magnified details, animation and interactive interface. Our method avoids the two defects in the references, that is, the visual cluster caused by discrete point tensor glyphs [1][2][3], and integration problem of hyperstreamline [6].
