Feasibility studies of combining drilling with casing and expandable casing
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)Nowadays, the biggest challenges in the oil business are the cost of operations versus the sizes of the prospect. We are drilling smaller targets and over the last few years, rig cost, service company rates and materials ... -
Feasibility study to perform coiled tubing drilling on Gullfaks-A
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-13)This report is carried out as part of Decision gate1 (DG1) feasibility study conducted for the possibility of commencing coiled tubing drilling to drill slim holes simultaneously with other drilling activities on Gullfaks ... -
Field-scale simulation modeling of disproportional permeability reduction impact on oil recovery
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Excessive water production in hydrocarbon exploration is a worldwide problem. The water produced is considered to be the largest waste stream by volume in during hydrocarbon production. Gelant/polymers have been known to ... -
Final field permanent plug and abandonment - methodology development, time and cost estimation, risk evaluation
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Quote from Douglas C. Nester, COO Prime Offshore LLC: “P&A obligation is like death; you can try to delay it for as long as possible, but sooner or later it will occur.”[1] Many wells on the NCS (Norwegian Continental ... -
