Optimization of a smart water composition for Enhanced Oil Recovery study by wettability alteration in carbonates at high temperature.
(Master thesis, 2021)Seawater due to its wettability modifying qualities has proved to be an excellent injection fluid in chalk. At high temperature seawater alter wettability towards more water-wet conditions thus improving the overall oil ... -
Optimized Smart Water Composition at Ekofisk Conditions
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-12)Seawater has been performing as a wettability modifier in chalk reservoirs and has been used for this purpose for a long time. This wettability alteration enhances microscopic then overall displacement efficiencies. Having ... -
Origin of anticline structure in the southern Hammerfest Basin and their impact in sedimentation and coarse-grained distribution
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)This thesis shows how extensional fault-related folding holds a fundamental control on basin physiography and syn-kinematic sediments. The study has used two- and three-dimensional seismic data in combination with a ... -
Path design and optimization with obstacle avoidance via reinforcement learning
(Master thesis, 2022)For the last couple of decades, finding an optimized drilling path has been one of the key concerns for drilling engineers. It takes a couple of months to plan a well for a large number of people. The motive of this thesis ... -
Petrophysical Evaluation of the Thinly Bedded Nordmela Formation in the Johan Castberg Field, Barents Sea
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07)This study demonstrates how contrasting different distributions of shale in a reservoir determines the petrophysical properties. The Skrugard prospect (Well 7220/8-1), drilled in 2011, confirmed that the western Barents ... -
Porosity prediction from seismic data of the F3 block, offshore Netherlands, through seismic inversion and machine learning
(Master thesis, 2022)Porosity is a key rock property that influences reservoir quality and plays an important role in petroleum exploration and production. The most common sources of information for reservoir characterization are well and ... -
Predicting appointment attendance at an outpatient clinic
(Master thesis, 2021)Abstract Background and aim: No-show, refers to patients who do not show up in the scheduled appointment, which is a serious problem for many years in the hospital. Also, the no-show rates differ in countries because of ... -
Predictive Dynamic Models of the Upper Jurassic Ula Fm Aquifer Between the Ula and Oda Fields, Norwegian Central Graben, North Sea
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07-15)The Ula and Oda oil fields in the southern part of the Norwegian Central Graben have high quality Upper Jurassic sandstone reservoirs from the shallow marine Ula Fm. Pressure data from the Oda field indicates communication ... -
Preparation and characterization of Nanocomposite gels for fracture plugging in chalks
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Excessive water production is a common challenge the oil industry is faced with. The lifting, treatment and disposal of produced water can cause a financial strain on the profitability of a hydrocarbon asset or even shorten ... -
Principle Component Analysis as a Method For Error Covariance Matrix Inflation
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-07-13)An oil and gas discovery goes through a multiple-stage process to increase the understanding of the asset in hand. By increasing the understanding of the field, production plan gains extra credibility and the uncertainty ... -
Probabilistic decline curve analysis with multiple models
(Master thesis, 2022)Numerical models have been established to help understand the longevity of projects when exploring and drilling for hydrocarbons. They aid in understanding and optimizing decisions on the long-term feasibility of a project ... -
Probabilistic Machine Learning for Production Optimization Under Uncertainty
(Master thesis, 2023)This thesis investigates the application of Bayesian Optimization (BO) in the optimization of the Expected Net Present Value (ENPV) for oil field development. The objective is to maximize the ENPV while reducing the ... -
Probabilistic Time Estimation for Drilling Operations on NCS Using Monte Carlo.
(Master thesis, 2021)The purpose of this thesis is to present a probabilistic methodology for developing time estimates for drilling operations on the NCS, which can further be expanded to supplementary continental shelfs in the world, or for ... -
Production of Smart Water by Acid Flooding in Chalk Cores: Oil Recovery Effects at Intermediate Temperature
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Considering that most carbonates are of low water wetness, it is of great interest to inject a brine that can alter the wettability to enhance oil production. Smart Water injection has therefore become the most meaningful ... -
Production of Smart Water by Acid Flooding in Chalk: Temperature Limitation at Slightly Water-Wet Conditions
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Seawater has proven to be an excellent injection fluid in chalk due to its ability to alter the wettability towards more water-wet conditions at high temperatures. This chemically induced wettability alteration improves ... -
