In defocusing detection system based on dual-quadrant detector, the defocusing curve would be affected if the light spot moves but not along the direction of the boundary between two quadrants.
The generalized Weng's model, dual logarithm production decline curve model and water drive curve model are popular to use in reservoir engineering study.
