Top-Down Model Development Using Data Generated From A Complex Numerical Reservoir Simulation With Water Injection, Yvon Andrea Martinez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Numerical simulation and data-driven modeling are two current approaches in engineering reservoir modeling. Numerical reservoir simulation attempts to match past production history by modifying reservoir properties of the model. After multiple computationally intensive trial and error efforts, accurate history matches are identified. These history matches are used by project management for production forecasting purposes. Data-driven reservoir modeling utilizes measured data and is, therefore, free of assumptions that are often included in numerical reservoir simulations. Artificial intelligence and machine learning algorithms are technologies implemented in the development of a data-driven reservoir model with efforts to learn fluid flow through porous media …

A Direct Data-Cluster Analysis Method Based On Neutrosophic Set Implication, Florentin Smarandache, Sudan Jha, Gyanendra Prasad Joshi, Lewis Nkenyereya, Dae Wan Kim

Branch Mathematics and Statistics Faculty and Staff Publications

Raw data are classified using clustering techniques in a reasonable manner to create disjoint clusters. A lot of clustering algorithms based on specific parameters have been proposed to access a high volume of datasets. This paper focuses on cluster analysis based on neutrosophic set implication, i.e., a k-means algorithm with a threshold-based clustering technique. This algorithm addresses the shortcomings of the k-means clustering algorithm by overcoming the limitations of the threshold-based clustering algorithm. To evaluate the validity of the proposed method, several validity measures and validity indices are applied to the Iris dataset (from the University of California, Irvine, Machine …

Breaking Coastal Hypoxia: Destratification Of Gulf Of Mexico Deadzone To Encourage Oxygen Transport Downwards To Maintain Marine Fauna, Veda Thipparthi

LSU Master's Theses

As a consequence of seasonal eutrophication and human input, a vast hypoxic area termed The Dead Zone develops every year in the Gulf of Mexico (GOM) during summer along the Louisiana coastline characterized by vertical seawater density-stratification with oxygen concentrations less than 2 mg.l^-1 at the seafloor. It poses a threat to bottom-dwelling faunae and their environment which has negative ecological and economic consequences. This project aims to mitigate hypoxia by employing mechanical impellers placed at strategic water depths and locations in the Gulf. Enhanced transport of oxygen results by mixing oxygen-enriched seawater at the surface, downward into the …

Volcanism Role In Formation Of Burned Breeds On Brown-Coal Fields Southern Fergana Coal Basin, A.E. Vorobev, O.Sh. Shamshiev, N.T Tolobaeva

Gorniy vestnik Uzbekistana

Are shown a volcanism role in formation of burned breeds on brown-coal fields of the Southern Fergana coal basin (Kyrgyzstan). So far burned breeds traditionally were considered as products of thermal transformation clay, clay алевритовых breeds, formed as a result of the underground fires of layers of coal. However, the complex of geological factors revealed recently when studying burned breeds, allows to assume their origin not only due to the underground fires of layers of coal, but also and a vol- canogenic and sedimentary way. Field works included supervision, drawing up litologo-petrographic, mineral and geochemical, structural and lithologic cuts with …

Mechanism Of Fluid Migration In Reservoirs-Collectors, A.E. Vorobev, Z.T. Martin, K.A. Vorobev

Gorniy vestnik Uzbekistana

The mechanism of fluid migration in stratium - reservoirs is revealed. The relevance of the study of the mechanism of migration of fluids is determined by the high (up to 90%) water cut of recoverable oil. It has been established that the migration of water and oil is mainly influenced by the type, nature and parameters of their interaction with host rocks, which have different values of wettability and sorption capacity. The amount of wettability is influenced by the pH values of water and oil. It is shown that pores and capillaries often have a mixed type of wettability, depending …
