Abstract:

As we have previously stated, this paper is part of a larger research aiming to build up econometric models applicable in oil industry that may be useful for managers working in this industry. In the first part, this paper deals with models that describe flat radial motions in porous environment with zonal constant permeability, namely flat radial motion in the case of the common contour both perpendicular to the direction of the motion and collinear with the direction of motion; also we introduce the Skin effect due to the existence of a modified permeability zone. In the second part, the article deals with three-dimensional motions generated by hydro-dynamically imperfect oil wells. These models will be useful tools for decision makers for an optimal management of oil wells production.
