Mountain geophysical prospecting operations play an important role in the entire petroleum exploration field. Geophysical drill-bit is main tool for mountain operations. Its hydraulic structure directly affects downhole flow field and then chip removal efficiency drilling of bit. At present, most scholars’ research focused on Poly Diamond Crystalline bit, roller etc., less, them study based cha...

Simulation technique has been used for a feasibility study of a prospecting project for deep seated ore bodies. The simulation model is divided into three main parts; 1) The bedrock model the mathematical model of the geology in the investigated block.. 2) The ore model the mathematical model of the "economical" targets within the investigated block. 3) The drilling model the mathematical descr...

We describe a multidisciplinary and interdisciplinary method to analyse the causes of differential macroseismic effects caused by an earthquake in a historical town. We illustrate the method with a case study based on analysing the damage caused by the 1930 Irpinia earthquake (Me=6.7) in Melfi, a town in southern Italy. A damage pattern map was already available for this site. To understand the...
