... on the predetermined shape of the trajectory using the minimum curvature method. Wellbore undulation (geometrical tortuosity) is determined using geometrical measurements such as inclination, azimuth, and calculated displacement; however, much of this wellbore undulation vanishes after the casing is run, and thus...

... that provide an averaged assessment of wettability. The first uses fundamental principles in topology to relate the contact angle to the integral of the Gaussian curvature over the fluid-fluid meniscus. The advantage of this approach is that it replaces the uncertain determination of an angle at a point...

... to monitor fluid configuration in the pore space and obtain fluid saturations and occupancy maps. Wettability was characterized by measurements of in situ contact angles and curvatures. The results show that the pore-scale mechanisms of improved recovery in LSW are consistent with the development of water...
