(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The primary objective of this thesis is to analyze and optimize drilling bits which were used to drill of an exploration offshore well in Norwegian Continental Shelf (NCS). The first part ot the thesis work reviews the ... -
Drill bits optimization in the Eldfisk overburden
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-29)Drill bits are a part of the well program. It is the major tool that does a cutting/crushing action at the end of the drillstring and highly affects the overall drilling performance. The following aspects can be improved ... -
Drill bits technology - introduction of the new kymera hybrid bit
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The early concepts of hybrid bits date back to the 1930’s but have only been a viable drilling tool with recent polycrystalline diamond compact technology. Improvements in drilling performance around the world continue to ... -
Drill string oscillations during connections when drilling from a semi-submersible platform
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)As the operational window is getting narrower, pressure control is becoming more important. Drilling from a semi-submersible platform can in this context offer new challenges as the top of the drill string will follow the ... -
