Determining optimal well placements and controls are two important tasks in oil field development. These problems are computationally expensive, nonconvex, and contain multiple optima. The practical solution of these problems require efficient and robust algorithms. In this paper, the multilevel coordinate search (MCS) algorithm is applied for well placement and control optimization problems. M...

Well placement planning is one of the challenging issues in any field development plan. Reservoir engineers always confront problem that which point should be drilled to achieve highest recovery factor and/or maximum sweep efficiency. In this paper, we use Opportunity Index (ROI) as a spatial measure productivity potential for greenfields, hybridizes reservoir static properties, and brownfields...

in distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. in this paper, the hybrid shuffled frog leaping algorithm (hsfla) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. high accuracy and ...

This thesis considers the placement problem in VLSI layout, which deals with layout optimization of integrated circuits. Most practical formulations of this problem are NP-hard. The most widely used formulations of this problem consider placement of rectangles within a rectangular container. The rectangles represent logical components and are called modules. Modules are connected by wires and a...

We propose two distributed optimization heurisitics for object placement in a distributed environment, and evaluate the communication cost incurred by several object placement strategies in the context of distributed First Person Shooter multiplayer games. We show that our heurisitics do as well or better than placement strategies that place objects statically or partition objects based on game...

This work presents methods for interconnect optimization while performing register optimization and placement of registers in memory. It has been shown that the port assignment problem is similar to the register optimization problem that also considers interconnect optimization. The basic formulation of the register-interconnect optimization problem has been posed as that of finding a clique co...

Compared to vertical or lowinclination wells, horizontal wells can deliver higher production rates, higher recovery factors, and more efficient use of steam in thermally enhanced recovery projects for heavy oil. However, the shallow, thin, and friable sand reservoirs in Columbia’s Girasol field present several challenges to the accurate placement of horizontal wells. Schlumberger was contracted...

The problem we consider in this article is motivated by data placement in particular data replication in video on demand systems. We are given a set V of n servers and b files (data, documents). Each file is replicated on exactly k servers. The problem is to determine the placement that minimizes the variance of the number of unavailable datas. To do that, we consider the problem of determining...
