The article is devoted to development of optimization methodology for parameters of oil rims exploitation system by line drive pattern of depletion type horizontal wells. Solution for transformation of flanking oil rim to subjacent oil rim with massive gas cap has been obtained. Moreover, empirical equation which includes gas cone height under exploitation of subjacent oil rim by horizontal well has been also derived. Known analytical solution has been supplemented with derived corrections with a view to convergence of the solution in the case of flanking oil rims. The solution includes set of dimensionless parameters which depend on formation characteristics and economic features of the project. Solution of the problem allows to determine the oil rim profitability without using complicated hydrodynamic computations at the stage of estimation.

This study makes an attempt to generalize the integrated modeling tools used by the authors in practice on the basis of the following criteria: the volume of the initial data, the integration mechanism, constraints and assumptions. Various types of integrated models are compared with each other, the need for their application is analyzed, they are connected at various stages of the project development and by the tasks solved at this stage. It also describes the challenges that the authors encountered when working with integrated models of various levels of detail, approaches to their solution, and the lessons learned.

In this article the horizontal wells productivity analysis has been hold in respect of edge-typed oil rims developed with depletion recovery drive with gas breakthrough. There are several methods that may help to calculate producion rate of the wells in underlayng oil rims without gas breakthrough (so called critical rate). These methods were obtained due to the relatively simple well drainage area. Considering the of edge-typed oil rim geometry with different saturation zones we get much more complicated boundary conditions and the numerical solution is needed. Main criteria that influence on the character of filtration flows in underlaynig and edge-typed oil rim were formulated. Various simulation runs on 2D "X-Z" model were perfomed to investigate coining peculiarities especially different coning regimes and it’s influence on the oil production rate. Main results of the work are the corrleations between dimensionless oil rate and geometrical parameters of edge-typed oil rim that also may help to calculate economical efficiency of the oil rim development.
