  • A folded wedge model for determination of true stratigraphic thickness in directional wells

    For exploration and development the geologists and engineers try to know the true stratigraphic thickness (t). The monoclinal and folded bed models are published methods for t calculation. Both models assume parallel beds which can lead to significant deviations. In order to calculate the values of t considering the effects of both folding and stratigraphic variation we propose the 'folded wedge ...
