Analytical modeling of sub-surface porous reservoir compaction
(Journal article; Peer reviewed, 2018)Fluid extraction has led to compaction, land subsidence, flooding and even earthquakes many places around the world. Although rare, the environmental costs could be overwhelming. Once compaction has been identified, possible ... -
Application of nature-inspired algorithms and artificial neural network in waterflooding well control optimization
(Peer reviewed; Journal article, 2021)With the aid of machine learning method, namely artificial neural networks, we established data-driven proxy models that could be utilized to maximize the net present value of a waterflooding process by adjusting the well ... -
Behavior of compacting reservoirs with restricted entry wells
(Journal article; Peer reviewed, 2019)We investigate the simultaneous effect of changes in thickness, permeability and porosity. These depend on changes in fluid pressure. Fluid withdrawal in stress-sensitive reservoirs may have serious environmental, technical ... -
Decision support method for early-phase design of offshore hydrocarbon fields using model-based optimization
(Journal article; Peer reviewed, 2019)This paper presents the development of a method to provide decision support in the feasibility studies and concept planning phases of oil and gas field development. The objective in developing the methodology was to provide ... -
Effect of drill pipe orbital motion on non-Newtonian fluid flow in an eccentric wellbore: a study with computational fluid dynamics
(Peer reviewed; Journal article, 2021)To ensure an effective drilling operation of an explored well, the associated hydraulics program should be established carefully based on the correct prediction of a drilling fluid’s pressure drop and velocity field. For ... -
Evaluation of surfactant flooding using interwell tracer analysis
(Journal article; Peer reviewed, 2017)Surfactant flooding is an important enhanced oil recovery (EOR) method, especially in carbonate oil reservoirs where water flooding may not have an effect on oil recovery as much as for sandstone reservoirs. This is because ... -
Experimental quantification of the performance of a horizontal multi-pipe bulk separator of water and oil with crude spiking
(Peer reviewed; Journal article, 2023)Subsea water separation with pipe separators is crucial for ensuring efficient and environmentally responsible extraction of oil and gas from the seabed. In this study, in a process called as “crude oil spiking,” two ... -
Laboratory study of plugging mechanism and seal integrity in fractured formations using a new blend of lost circulation materials
(Peer reviewed; Journal article, 2023)The problem of lost circulation occurred long during the drilling operation. Through induced and natural fractures, huge drilling fluid losses lead to higher operating expenses during the drilling. Historically, this problem ... -
Machine learning algorithm for prediction of stuck pipe incidents using statistical data: case study in middle east oil fields
(Peer reviewed; Journal article, 2022)One of the most troublesome issues in the drilling industry is stuck drill pipes. Drilling activities will be costly and time-consuming due to stuck pipe issues. As a result, predicting a stuck pipe can be more useful. ... -
Million node fracture: size matters?
(Peer reviewed; Journal article, 2021)Transmissivity of self-affine fractures was computed numerically as a function of the grid size. One-million-node fractures (1024 × 1024 nodes) with fractal dimensions of 2.2–2.6 were cut into successively smaller fractures ... -
A new approach for real-time prediction of stick–slip vibrations enhancement using model agnostic and supervised machine learning: a case study of Norwegian continental shelf
(Journal article; Peer reviewed, 2023)Efficient and safe drilling operations require real-time identification and mitigation of downhole vibrations like stick-slip, which can significantly diminish performance, reliability, and efficiency. This pioneering ... -
Optimized production profile using a coupled reservoir‑network model
(Journal article; Peer reviewed, 2019)This paper presents an integrated approach for scheduling and forecasting oil and gas production by integrating models of the entire value chain, from the reservoirs to the sales points. The methodology ensures maximum oil ... -
Performance evaluation of a multi‑branch gas–liquid pipe separator using computational fluid dynamics
(Journal article; Peer reviewed, 2019)The present paper aims to evaluate the performance of a multi-branch gas–liquid pipe separator by means of 3D computational fluid dynamics. This type of separator is attractive for deepwater subsea hydrocarbon fields due ... -
Petrophysical interpretation in shaly sand formation of a gas field in Tanzania
(Journal article; Peer reviewed, 2019)An onshore gas field (hereafter called the R field—real name not revealed) is in the southeast coast of Tanzania which includes a Tertiary aged shaly sand formation (sand–shale sequences). The formation was penetrated by ... -
Simulation study of surfactant injection in a fractured core
(Journal article; Peer reviewed, 2019)Surfactant flooding could be used to improve water flooding in fractured reservoirs due to the main mechanisms of wettability alteration and interfacial tension reduction. However, the surfactant flooding in fractured ... -
Superstructure optimization of subsea processing layouts
(Journal article; Peer reviewed, 2023)As the oil and gas industry expands the use of subsea processing, the complexity of subsea layouts increases, making manual design processes cumbersome and suboptimal. Here we propose a method to support subsea field design ... -
Using combinatorics to compute fluid routing alternatives in a hydrocarbon production network
(Journal article; Peer reviewed, 2017)Typically, hydrocarbon production networks have several fluid routing alternatives that are applied by opening and closing on–off valves. This usually sends the wells’ fluids through a specific pipeline, pump or compressor, ...
