Model for Kick Tolerance
(Master thesis, 2012)Kick Tolerance is an important factor in the industry, that allows drilling engineers to establish several parameters in the development phase of a well, such as casing depths, open hole lengths, etc. It can also be ... -
Model for Prediction of Cement Sheath Failure
(Master thesis, 2016)In casing design, the casing is required to withstand all loads it is exposed to during the well life. These loads are normally modeled in an industry leading software (ILS), which determines whether the casing can withstand ... -
Model of Hook Load During Tripping Operation
(Master thesis, 2013)Drilling after oil and gas becomes more challenging for every drilled well; deeper, longer, harder, higher temperature, higher pressure and more complex conditions. The equipment requirements and well integrity regulations ... -
Model-Based Gas Lift Optimization for Oil Well Networks Using Python and PROSPER Well Models
(Master thesis, 2023)In the oil industry, continuous flow gas lift is a frequently employed artificial lift technique to boost oil recovery by decreasing bottom hole pressure. By injecting high-pressure gas into the tubing, the oil column can ... -
Model-based optimization of production systems
(Master thesis, 2015)Gas lifted method is one of the artificial lift technique used in the oil and gas industry.This method is applied most in oil well to improve the oil recovery by lowering the bottomhole pressure. Normally in the field there ... -
Modeling alternatives for multiphase boosters, for field performance studies
(Master thesis, 2017)The concept selection for the development of a petroleum field critically depends upon the uncertainties involved in the field performance analysis, and any deviation in the actual field production from the originally ... -
Modeling and Analysis of Liquid Loading Phenomena and Its Impact on Crossflow in Gas Wells Using ROCX and OLGA
(Master thesis, 2023)Denne oppgaven undersøker samspillet mellom reservoar og brønn under væskeopphopning (liquid loading). Det kan oppstå kryss-strømninger mellom reservoarsoner med ulike egenskaper, og denne oppgaven undersøker om ... -
Modeling and characterizing acoustic signals from cavity clouds generated by marine seismic air-gun arrays: Implications for marine mammals
(Doctoral theses at NTNU;2018:239, Doctoral thesis, 2018)Marine seismic air-gun arrays generate not only low-frequency (<∼300 Hz) acoustic waves which benefit seismic imaging, but also high-frequencies up to tens of kilohertz. Although such high-frequencies are much weaker than ... -
Modeling and Inversion of Marine Electromagnetic Data: – with applications in hydrocarbon prospecting
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:67, Doctoral thesis, 2013)This thesis deals with modeling and inversion of electromagnetic data for geophysical applications. The main topic is modeling and inversion of marine Controlled Source Electromagnetic (mCSEM) data, but joint inversion of ... -
Modeling and Management of Scale Potential in an Oil Field Production Network
(Master thesis, 2013)Diversity and complexity of chemical treatment operations provide difficulties to evaluate an impact of chemicals used for solving different production issues. Integrated chemical management system will provide a better ... -
Modeling and Optimization of the Rich Gas-Condensate Reservoir: Upstream, Midstream and Downstream Integration
(Master thesis, 2013)Simulation and Optimization of the production assets occurs in several and various cycles.Those are: "Field Management", "Production Optimization" and "Operation Efficiency". Decisions making process obviously based on ... -
Modeling and Prediction of Borehole Collapse Pressure during Underbalanced Drilling in Shale
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:39, Doctoral thesis, 2011)Drilling with a bottomhole pressure less than the formation pore pressure (underbalanced) will usually increase the risk of borehole collapse due to yielding or failure of the rock adjacent to the borehole. Understanding ... -
Modeling burial induced changes in physical sandstone properties - A case-study of North Sea and Norwegian Sea sandstone formations
(Master thesis, 2017)The changes in physical properties of sandstones with burial depth are a result of mechanical and chemical compaction processes. These processes are affected by rock microstructure, pressure regimes and temperature history. ... -
Modeling CO2 Injection in Fractured Reservoirs Using Single Matrix Block Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:101, Doctoral thesis, 2011)In this thesis, CO2 injection in matrix/fracture systems has been studied using a finely-gridded compositional simulator representing a single matrix block. Three laboratory experiments were modeled to investigate whether ... -
Modeling compositionally-sensitive reservoirs
(Doktoravhandlinger ved NTNU, 1503-8181; 59, Doctoral thesis, 2002)This research work provides guidelines for choosing the PVT model (black-oil or EOS compositional) for full-field reservoir simulation of volatile/near-critical oil and gas condensate fluid systems produced by depletion ... -
Modeling fluid flow around an air gun bubble
(Master thesis, 2014)In marine seismic acquisition, the bandwidth of the recorded signal is limited, on both the low and high end, and it is usually accepted that by towing the source deeper the low-frequency content in the seismic data increase. ... -
Modeling interfacial tension of the hydrogen-brine system using robust machine learning techniques: Implication for underground hydrogen storage
