Cuttings Transport With Oil- and Water-Based Drilling Fluids
Journal of Energy Resources Technology, 2021 Abstract Deviated well sections are common in most modern offshore well construction designs. In the North Sea region, which is a good example of mature areas, practically all producer or injector wells have highly deviated well sections. These wells must be constructed in an optimal manner with respect to functionality, drill time, risk,
