Well Control Optimization by Coupling Smart Proxy Models with Genetic Algorithm
(Master thesis, 2021)Generally, optimal well controls to maximize net present value (NPV) are obtained by coupling of numerical reservoir simulation with an optimization algorithm. This approach requires a significant number of numerical ... -
Well Control Optimization in Waterflooding Using Genetic Algorithm Coupled with Machine Learning Models
(Master thesis, 2020)Generally, optimum well controls to maximize net present value (NPV) in a waterflooding operation are obtained from a numerical reservoir simulation in combination with an optimization algorithm. This procedure is often ... -
Well control with Controlled Mud Pressure: Reviewing AGR’s well control procedures for the CMP system, analyzing and comparing with conventional well-control procedures, possible impact of technology.
(Master thesis, 2011)Dual Gradient Drilling (DGD) are a portfolio of drilling systems that in various ways pumpreturns from the well through a mud return line (MRL) from the seafloor, or somewhere between the seafloor and the rig floor. Two ... -
Well control with Low Riser Return System
(Master thesis, 2011)A response to the increasingly more challenging prospects to drill, due to depletion of old reservoirs and increasing water depths, is the Low Riser Return System (LRRS). The LRRS is a system designed to manage the wellbore ... -
Well Integrity Assessment: Challenges related to Human and Organizational Factors - The case study of Veslefrikk
(Master thesis, 2015)Well integrity affects safety, humans, the environment, production, reputations and assets value. The concept of well integrity in relation to human and organizational factors have gained considerable attention in the ... -
Well Integrity behind casing during well operation.Alternative sealing materials to cement
(Master thesis, 2013)Maintaining well integrity during all well operations has become a major concern for operators worldwide. The maintenance of an increasingly aging well stock and the higher cost associated with new wells makes well integrity ... -
Well Log and Seismic Data Interpretation: Rock Physics Study of Poorly Consolidated Sandstones in The North Sea
(Master thesis, 2012)We use rock physics models for poorly consolidated rocks to diagnose reservoir sandstones in the Alvheim Field, North Sea. Geological factors that will control the rock physics and seismic properties include clay content, ... -
WELL LOG ZONATION AND CORRECTION BASED ON VARIATIONS IN AMPLITUDE AND LAYER THICKNESS
(Master thesis, 2011)Well log zonation is the usual practice to carry out well log analysis. Definition of bed boundaries at a very detailed level is difficult and time-consuming, and therefore some data is frequently untapped, especially when ... -
Well Models for Production Optimization
(Master thesis, 2008)In coupled reservoir simulations a model of a reservoir and the production system are joined together to obtain realistic responses. One way of performing production optimization is to make use of a gas oil ratio (GOR) ... -
Well Path Optimization on a CO2 EOR Project
(Master thesis, 2019)Optimering er eit heller nytt emne i petroleumsindustrien, men har i det siste sett auka interesse. Innanfor EOR, eller Enhanced Oil Recovery, kan optimeringstilnærmingar bli implementert for meir fordelaktige brønnbanar. ... -
"Well Placement for maximum production in the Norwegian Sea": Case Study: Norne C-segment Oil Field
(Master thesis, 2012)In petroleum fields, the essence of well placement is to develop and maintain petroleum reservoirs in order to achieve maximum production for economic benefit. Maximum production can be achieved with more oil wells, but ... -

Well Production Decline
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:174, Doctoral thesis, 2009)Effective rate-time analysis during a declining production in an oil or gas wells is an important tool for establishing a successful management. The reasons behind the production decline include reservoir, fracture ... -
Well production forecast in Volve field: Application of rigorous machine learning techniques and metaheuristic algorithm
(Peer reviewed; Journal article, 2021)Developing a model that can accurately predict the hydrocarbon production by only employing the conventional mathematical approaches can be very challenging. This is because these methods require some underlying assumptions ... -
Well Safety. Risk Control in the Operational Phase of Offshore Wells
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:47, Doctoral thesis, 2006)The main objective of this thesis has been the development of procedures and methods for risk assessment of oil and gas wells. The work is limited to the well operational phase. The procedures and methods provide status ... -
