WebThe measured contact angle usually indicates the degree of wetting. A contact angle of less than 90° indicates a greater wetting of the surface (higher wettability), and the liquid … WebJul 9, 2024 · The contact angle is the angle at the interface where water, air and solid meet, and its value is a measure of how likely the surface is to be wetted by the water. Methods for determining initial fluid contacts are listed in Table 1 and are discussed by Bradley. These include fluid sampling methods, saturation estimation from wireline logs, estimation from conventional and sidewall cores, and pressure methods. Once initial fluid contact elevations in control wells are determined, the … See more The transition zones calculated for homogeneous reservoirs may be relatively thin, particularly in coarse-grained reservoirs. However, thick transition zones are observed in many fields due to reservoir … See more bright colored baby boy clothes
