The importance of core drilling to the exploration and exploitation of the earth's natural resources and to the integrity of engineering structures is highlighted. An investigation of the slim hole continuous core drilling system and its application in the oil and gas exploration is analysed.A Computational Investigation of the Laser Bonding of Balloon Catheters By Enda Ryan A thesis submitted to the National University of Ireland as fulfilment of the requirements for the Degree of Doctor of Philosophy Department of Mechanical and Biomedical Engineering National University of Ireland, Galway November 2014.PhD Thesis. Geometric Processing Techniques for Urban Aerial Laser Scan Data. My PhD studies focused on the acquisition and processing of high resolution Aerial Laser Scanning (ALS) data sets. In particular, processing task such as building extraction and modeling for urban areas were studied.

II DEDICATION This work is dedicated to my parents and my elder brother to whom I owe so much for my achievements.

LASER MACHINING OF CARBON FIBRE REINFORCED POLYMER COMPOSITE A thesis submitted to The University of Manchester for the degree of Doctor of Philosophy (PhD) in the Faculty of Engineering and Physical Sciences 2016 Adel Salama School of Mechanical, Aerospace and Civil Engineering.

Hole tapering is one of the inherent manufacturing problems associated with laser percussion drilling (multiple pulse drilling) whereby material is ejected in the form of molten droplets when a series of laser pulses are delivered to a point on a workpiece.

New thesis on drilling technology. Milad Khatibi defended his doctorate on 14 November. His PhD thesis sheds new light on particle transportation in petroleum wells. Del artikkel: Hole-cleaning operations are of major concern while drilling petroleum wells. During drilling, particles from the reservoir are transported with the drilling liquid.

In this thesis, some new features were proposed into the femtosecond laser drilling area in order to overcome these problems. In this study, the effect of six alcohol liquids on the fs laser drilling process was evaluated and compared. The relation between the volatility of the liquids and the material removal rate of laser drilling was found.

A PhD is a Doctorate of Philosophy, a prestigious qualification that demonstrates talent, academic excellence and a thirst for knowledge. It usually culminates in a thesis based on research carried out over the course of 3-4 years.

The idea of cutting with light has appealed to many from the first time they burnt paper on a sunny day with the help of a magnifying glass. Cutting centimetre-thick steel (Figure 3.1) with a laser.

At the present moment, what is the best subject for a MSc thesis in Petroleum Engineering? Something related with Production, Drilling and Reservoir Engineering. Thanks.

The laser interferometer can measure decay induced contraction or expansion of stones on the nanometre scale. Salt crystallisation in porous systems can be examined with very high precision under any temperature and humidity condition that enable salt growth.

Thus, cladding-pumped Raman fibre laser sources are a kind of brightness enhancers. In the beginning of this thesis, I theoretically analyse various factors that limit the brightness enhancement of such devices. One of the limits is unwanted 2nd-Stokes generation, which restricts the area ratio between the inner cladding and core.

Overview. The PhD programme in Petroleum Engineering is connected with research within each of these specialist areas. Within the area of reservoir engineering, research includes modelling and measuring physicochemical processes from pore-scale and upwards with a view to increase the amount of extraction from rocks containing oil.
