A feasibility study for drilling & completing ERD wells on the Brage field
(Master thesis, 2015-06-12)In this master thesis, the potential for drilling an ERD well from the Brage platform have been studied. ERD wells can help operators reach isolated reservoirs located far away from the drilling facility. For mature fields ... -
Addressing zonal isolation challenges and improving 9 5/8" production liner primary cement jobs across the Valhall field
(Masteroppgave/UIS-TN-IØRP/2014;, Master thesis, 2014-06-12)Placing cement in the annulus between a casing string and the borehole is essential to obtain compliant zonal isolation. Circumferentially bonded cement provide a hydraulic seal which prevents cross flow between permeable ... -
Calculation of forces acting on a rotary steerable liner drilling system
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)Torque and drag calculations performed on a new liner drilling design indicate that a very high grade drillpipe, up to S-135, is required in order to satisfy the requirements which both axial and torsional loading place ... -
Computational Fluid Dynamics (CFD) study to optimize simulated pressure drop across liner hangers: A field trail approach to improve well integrity by optimizing ECD simulations during well cementing.
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-06-15)Optimizing cementing parameters during the cement job is a challenging task. Accurate pre-job analysis is essential to elude breakdown of the formation to obtain a successful cement job. If the equivalent circulation density ... -
Drilling problems in depleted reservoirs
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)New oil and gas wells are becoming more challenging to drill. New technology and better understanding of new and existing reservoirs become available, pushing the envelope of what is technically possible and economically ... -
Evaluation of the primary cement operation on the production casing in the Ekofisk field and the Eldfisk field
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The foremost goal of primary cementing is to provide zonal isolation in a well. Cementing of the casing/liner set right above the reservoir on the Ekofisk and Eldfisk fields are associated with a lot of challenges. ...
