| Well placement decisions must be made in the face of geological, engineering and economic constraints. Some of these constraints include (1) maximum intersection of connected volumes of high quality reservoir, (2) avoidance of fluid contacts that could cause early breakthrough and reduce productivity, (3) maximum pore volume that could be drained, (4) compliance with existing wells as well as physical drilling constraints.;A fast and efficient iterative algorithm based on simulated annealing is proposed for well planning subject to multiple constraints and uncertainty in the reservoir model. Connected volume and pore volume are used as the main criteria in our examples. Several examples from simple to real reservoir models for placement of different number of wells and well types are tested and presented. |
