Nano-based Elastomer Swelling Agent
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)With multistage hydraulic fracturing and extended reach wells becoming increasingly common, the need for effective annular zonal isolation has become paramount. In such wells, swell packers are being preferred over traditional ... -
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 ... -
New generation expandable sand screens
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-12)This thesis aims to give a general insight into sand control and various sorts of sand control measures and applications of sand control tools. Special focus will be given to expandable sand screens – a technology which ... -
New methodology for foam cement mixing to better reflect onsite mixing method
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Foamed cement has become a well established cementing method for many applications in oilwell cementing all over the world. A key factor to a successful foam cement job is an optimized cement slurry design. To achieve ... -
New technology trends for effective plug and abandonment
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-08)Plug and Abandonment (P&A) has become a major focus in the petroleum industry and especially in Norway due to the maturity of the fields. Therefore, an extensive number of wells to be abandoned just show how big the challenge ... -
Numerical Simulation and Experimental Study of Reelwell’s Heavy over Light Solution in Vertical Well Sections
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Reelwell has developed the Reelwell Drilling Method (RDM), including the Heavy Over Light (HOL) solution. The HOL solution allows drilling with simultaneously use of two different drilling fluids, i.e. a near static ... -
Numerical simulation of chemical flow-zone isolation
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Silicate gel has been mostly used for near well treatment. A field test in the Snorre reservoir on the Norwegian Continental Shelf (NCS) has been planned, where the object of the test is to technically qualify silicate gel ... -
Numerical simulation of co-current and counter-current imbibition
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Spontaneous imbibition (SI) is a very important mechanism for oil recovery in naturally fractured reservoirs. Several studies have indicated that counter-current oil production is much slower and give lower ultimate oil ... -
