A historical development of P&A requirements on the NCS and its effects on permanently plugged and abandoned wells
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-07-13)This master thesis presents the development of the regulation in the field of permanent plug and abandonment in the Norwegian Continental Shelf (NCS). It describes how the regulations have been developed for Permanent Plug ... -
An Introduction to the Welltec Annular Barrier and its Interaction with the Open Hole Formation
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Developments in drilling have opened for the construction of extended reach wells. They can have large intermediate and reservoir sections, which may need zonal isolation. To isolate the different zones, Welltec has developed ... -
Application of thermo-mechanically treated drill cuttings as an alternative to bentonite in spud muds
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-05-22)Drill cuttings recovered after drilling with OBM today are treated and deposited at onshore facilities. The TWMA Company offers a new technology, which recovers drilled subsurface materials together with oil and water ... -
NCS Drilling Data Based ROP Modelling and its Application
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Predicting the ROP (rate of penetration) before drilling is essential to improve the overall drilling efficiency and thereby reduce the non-productive time and costs. For this, good ROP model is required. Several ROP models ... -
Uniform Corrosion and Its Effect on Tubing Simulation Study
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-07-13)The API Barlow and the Tri-axial equations cannot be applied to predict burst pressure in the case of pitting corrosion. The main reason for this is that these models are derived from continuum mechanics, but fracture ...
