Measurement of gas fraction in gas-liquid flow using a buoyancy sensor
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-07-13)In this thesis, an innovative new method for measuring in-situ gas fraction in vertical flowing pipes is proposed as an alternative to using differential pressure. The new method has been tested by developing an experimental ... -
Mitigating Stick-Slip Vibrations Using Surface Control Software - A Validation of SoftSpeed II™ Using High-Speed Along-String Dynamics Measurements in a Norwegian Offshore Field
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-05-30)Stick-slip is a well known drilling related problem that causes damage and delays, often resulting in an overall more expensive well. These problems have traditionally been remedied by reducingWOB or increasing RPM ... -
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 ... -
