Numerical Optimization of Hydraulic Fracture Stage Placement in a Gas Shale Reservoir

The upstream oil and gas industry focuses increasingly on unconventional gas resources to maintain the level of its hydrocarbon reserves. To unlock the full potential of gas shale reservoirs, horizontal wells are drilled and active stimulation of the reservoirs, in the form of multi-stage hydraulic fracturing, is performed. This new technique...

A Fuzzy Decision Support System for Magnetic Component Design

In many areas of electrical engineering, magnetic components like transformers and inductors are necessary parts of an electrical circuit. Designing such a component means finding a suitable combination of a ferrite core and a copper wire, while a great variety of requirements have to be satisfied. However, finding the optimal combination is...
