When mechanically induced progressive failure of rock and the associated changes in hydro fracturing process, it is difficult to track the dynamic evolution of fractures beneath the earth. To overcome this, recent developments in hydro-fracturing technique have tended to follow hybrid approaches. An attempt was made to develop an empirical relationship to predict the Fracture length in millimet...

Optimizing parameter settings is an important task in algorithm design. Several automated parameter tuning procedures/configurators have been proposed in the literature, most of which work effectively when given a good initial range for the parameter values. In the Design of Experiments (DOE), a good initial range is known to lead to an optimum parameter setting. In this paper, we present a fra...

Drilling thrust force calculations require a large amount of experimental work, which can be greatly reduced, since an extensively validated CAD-based approach, using the DRILL3D software application, has become available. DRILL3D calculates the thrust force of both the cutting areas of the tool (main edges and chisel edge) simultaneously, which means that every simulation can substitute two se...
