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. This article deals with three-dimensional motions, and hydro-dynamically imperfect oil wells were introduced as there are several types of such defects. In the first part, this paper deals with models that describe spherical radial motion, while in the second part, deals with motion generated both by a partially penetrating oil-well, and by an imperfect oil-well according to its opening mode. In the end, inactive soleplate water cones are largely addressed. These models will be useful tools for decision makers for an optimal management of oil wells production.
