A Comparison of Analytical and Experimental Procedures to Verify a Lumped Drill String Element Model
Hassan, Raz Taha (Master thesis, 2016)A study of axial vibrations in a vertical drill string is conducted using a spring-mass-damper model with n coupled elements. The main motivation behind this is to describe the axial vibrations using a simple mathematical ... -
Analysis of cuttings concentration experimental data using exploratory data analysis
Chowdhury, Dipankar; Hovda, Sigve; Lund, Bjørnar (Peer reviewed; Journal article, 2022)Cuttings transportation is a complex phenomenon involving many inter-acting variables. Experimental investigations on cuttings transport are carried out by different research groups for decades and varying findings are ... -
Analysis of Kick Detection Methods in the Light of Actual Blowout Disasters.
Lindi, Oltingey (Master thesis, 2017)Kicks or formation fluid influxes pose persistent challenges and operational costs during drilling, workover, completion and sometimes after temporary abandonment operations. Despite of presence of variety of kick detection ... -
Analysis of Stick-Slip Effects During Oil-Well Drilling
Zhao, Dapeng (Doctoral theses at NTNU;2017:127, Doctoral thesis, 2017)The drilling operation is a costly portion of the upstream petroleum industry. It is worth making efforts to reduce unwanted non-productive time (NPT), which is often induced by downhole problems during drilling. In this ... -
Applications of Equations of State in Blowout and Relief Well Kill Simulation
Nilsen, Marius Staahl (Master thesis, 2016)A blowout is the most severe consequence of a well operation, and may cause a high negative impact on the surrounding environment and human safety, and financial distress for responsible companies due to clean up costs, ... -
Automatic lithology prediction from well logging using kernel density estimation
Corina, Anisa Noor; Hovda, Sigve (Journal article; Peer reviewed, 2018)Technologies of real-time data measurement during drilling operation have kept the attention of petroleum industries in the past years, especially with the benefit of real-time formation evaluation through logging-while-drilling ... -
Automatic Lithology Prediction from Well Logging Using Kernel Density Estimation
Corina, Anisa Noor (Master thesis, 2016)This thesis presents an automatic real-time analysis of lithology interpretation through a method of statistical analysis: kernel probability density method. The goal of this thesis is to develop a method for interpreting ... -
Automatic Lithology Prediction on Well Logs Using Kernel Density Estimation Trained By Analysis of Cuttings Data
Strømslid, Simen Kristoffer Steiro (Master thesis, 2017)Lithology interpretation is a vital part of the process when drilling oil and gas wells in the petroleum industry. The ability to predict what problems and challenges can occur along the well path and which precautions ... -
Cuttings bed erosion using a selection of interstitial fluids
Mo, Hanna Imsland; Tolla, Mercy Abebe (Master thesis, 2024)I boreoperasjoner kan effektiv hullrensing være utfordrende. Borekaks har en tendens til å samle seg langs borehullsveggen, noe som kan føre til fastkjørte borerør, brudd, redusert borehastighet (ROP) og andre problemer ... -
