Sammanfattning : .... LÄS MER
2. Geophysical studies of the upper crust of the central Swedish Caledonides in relation to the COSC scientific drilling project
Sammanfattning : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. LÄS MER
3. Parameters optimization of oil well drilling operation
Sammanfattning : In the beginning of 2005, the ministry of natural resources in the Kurdistan region of Iraq dividedits territory into more than 50 oil blocks based on geological setting. These oil blocks were awardedlater to different international oil companies for oil investments based on Production SharingContracts (PSCs). LÄS MER
4. Positional Accuracy of Drilled Holes
Sammanfattning : When selecting hole-making sequences, the positional accuracy mainly is determined during the first drilling operation. This dissertation consists of three papers which consider the influence of various factors on hole positional accuracy when drilling in inclined workpieces using high-speed steel twist drills with conventional point geometry.

5. On the Nature of Cemented Carbide Wear in Rock Drilling
Sammanfattning : WC/Co cemented carbide is a composite material for highly demanding wear applications. The unique combination of hardness (from the WC-phase) and toughness (from the binder Co) gives a material especially suitable for rock drilling. LÄS MER
