High energy explosions and irradiation may cause that the minerals and mineraloids form glassy phase on the earth surface. We would like to determine the mechanical properties of these glassy materials. To achieve this and manufacture samples we need to measure the main technological property, the viscosity. © (2015) Trans Tech Publications, Switzerland.

Our research team has developed a new well completion and rework technology involving lasers. The system is made up of a high-power laser generator and a custom-designed directional laser drilling head. The laser head is attached to a coiled tubing unit to maximize production and to carry out special down hole tasks. In this phase of the development effort, laser technology is particularly well suited to cost-efficiently drill short laterals from existing wells in a single work phase, drilling through the casing and cement as well as the formation. The technology, which is an extended perforation solution, enables a more intensive interaction with the down hole environment and supports cutting edge subsurface engineering scenarios such as barite removal. Laser-induced heat treatment appears to be a suitable alternative to effectively remove the almost immovable deposits and scales from thermal water-well pipes. © 2015 Akadémiai Kiadó, Budapest.

A method and system for restoring flow capacity to a submerged fluid conduit comprising a laser light apparatus to generate blue laser light to be impinged on the fluid conduit. The method and system include a frequency multiplier (15) for converting infrared laser light from a laser light generator (14) to blue laser light having a higher transmissivity in seawater. The frequency multiplier may be disposed on a submergible vehicle (2). In one embodiment, a non-submerged infrared laser light generator (14) supplies, via optical conduits (21), laser light to a submerged frequency multiplier (15) on the vehicle (2). Blue laser light, at a wavelength in the range of 440-500 nm, is emitted through an optical window and through seawater to impinge on the surface of the fluid conduit.
