Three-dimensional eolian bounding surface architecture of the Entrada sandstone, Utah: expanding our understanding of reservoir heterogeneity in wet eolian systems
… Eolian deposits form noteworthy petroleum reservoirs (e.g., Norphlet Formation, Rotliegend Group, and the Tensleep Sandstone), but bounding surface architecture imparts significant reservoir heterogeneity. In order to understand dune morphodynamics, reconstruct ancient erg evolution, and …

Reservoir Characterization and Outcrop Analogs to the Navajo Sandstone in the Central Utah Thrust Belt Exploration Play
Reservoir heterogeneity plays an important role in oil field economics and completion strategies. We herein characterize the reservoir heterogeneity of the Early Jurassic Navajo Sandstone in the Justensen Flat/Devils Canyon area of the San Rafael Swell, Utah. These outcrops are located …

Application of Dynamic Upscaling for Thermal Reservoir Simulation
Reservoir simulation is inherently an imperfect tool for forecasting. However, given sufficient analysis and post-processing, the areas of uncertainty can be quantified and effort can be made to mitigate their impact and improve the confidence in the prediction. The focus of the research documented …

Analytical Modeling of Multi-Fractured Horizontal Wells in Heterogeneous Unconventional Reservoirs
… horizontal wells (MFHW) generally neglect reservoir heterogeneity, typical seepage characters of unconventional reservoir, partially penetrating fracture and various fracture damage mechanisms. In this thesis, three linear flow models have been developed to facilitate pressure and rate …

Identification of technical barriers and preferred practices for oil production in the Appalachian Basin
… water production, poor understanding of reservoir heterogeneity, limited availability of compatible water for water injection, lack of sufficient reservoir data such as permeability, porosity, and primary production data for reservoir characterization, and paraffin and asphaltene causing …

Rate Optimization for Polymer and CO2 Flooding Under Geologic Uncertainty
With the depletion of the existing reservoirs and the decline in oil discoveries during the last few decades, enhanced oil recovery (EOR) methods have gained a lot of attention. Among the various improved recovery methods, waterflooding is by far the most widely used. However, the presence of …

Semantic model and updated screening criteria for polymer flooding
… interfacial forces, heavy oil viscosity, and reservoir heterogeneity make it difficult to produce. Many EOR methods are available but usually cannot be used at the same time for a candidate reservoir. Therefore, it is important to select the most appropriate EOR process from among the possible …

A novel approach to upscaling reservoir simulation modelling for polymer processes
… that involves injecting polymer solutions into reservoirs to improve recovery efficiency. Key mechanisms such as mobility control, polymer-rock interaction, gravity segregation, viscous crossflow, and reservoir heterogeneity govern fluid displacement and sweep efficiency. While detailed grid …

Interwell Connectivity Evaluation from Wellrate Fluctuations: A Waterflooding Managment Tool
… data for these purposes. Early studies involving reservoir simulation have shown CM to be a valuable tool but also have revealed several shortcomings. Many of these deficiencies have become more transparent in analyzing field data. This work consists of two parts: in the first part, we investigate …

A geo-cellular model of a multiphase hydrocarbon field incorporating fault-seal analysis : Bredasdorp Basin, South Africa
… The 3D model becomes the basis upon which reservoir heterogeneity and characterisation are understood, hydrocarbon volumetrics are calculated and field development plans are designed. Reservoir compartmentalisation and fault-seal analysis is also an industry topic which has drawn much …

Sediment Heterogeneity and Sand Production in Gas Hydrate Extraction: Daini-Atsumi Knoll, Nankai Trough, Japan
… the failure mechanism is not the same for all reservoirs and the location of reservoir porosity and pressure on the normal compression line for sands could be a controlling factor. Sand production in reservoirs at shallow depths and low confining stresses (less than 10 MPa) are likely to be …
