... the depletion in a 3D heterogeneous reservoir model to that of an equivalent 1D model. In this paper, a practical approach to handle highly heterogeneous matrix properties for dual porosity FMM simulation is established. Various averaging methods for the heterogeneous matrix properties are examined through...

... show that reservoir management is the main driver behind the well performance control in this high heterogeneity water flood system. The use of proper production surveillance management techniques, allows selecting technologies which will bring a project to success when heterogeneities play...

... heterogeneity. We use dynamic models on scales from field to plug combined with economic evaluation to improve the selection and to support decision-making. Identification of the most sensitive parameters such as reservoir connectivity, current oil saturation, production allocation and polymer retention...

... the on-going execution of the EOR pilot project. Several static/dynamic models are built at different scales (from 10 km to 100 m) to capture depositional trends and model stratigraphic and sedimentary heterogeneities. We evaluate different physical aspects of the polymer injection process with specifically...

... Abstract This paper discusses the successful, fully integrated petrophysical and geological modeling of the Hollin formation in the Sacha field of Ecuador. The goal of the modeling project was to unravel aquifer heterogeneities and hydrodynamic effects; it focuses on suitable petrophysical rock...

... Abstract This paper discusses the successful, fully integrated, three-dimensional (3D) earth modeling (EM) and dynamic reservoir simulation of the Hollin formation in the Lago Agrio field within an operator's first producer field in Ecuador. Early feedback of reservoir heterogeneity helped...

... was evaluated from coreflooding at two different pressures, above and below the MMP of 1563 psig The MMP was experimentally determined using a fast version of the slim tube procedure with a shorter column. The influence of reservoir heterogeneity was observed by conducting corefloodings in homogeneous...

... Abstract A correlation between Computed Tomography (CT) number, matrix porosity, and permeability is presented that enables the petrophysical characterization of highly heterogeneous reservoir rocks with a level of detail that is not achievable by direct laboratory measurements. A total of 143...

... rocks with high heterogeneity in several scales of investigation. The representative elementary length plays a major role to characterize such reservoirs. The present work describes a quantitative approach to determine the size of a representative elementary area (REA) using both numerical...

... Abstract Improved oil recovery is more sensitive to sub-log scale heterogeneity than primary recovery processes. Determination of porosity, net-to-gross, saturation and permeability, both magnitude and direction, at scales below log resolution is often required in secondary and tertiary...

... and heterogeneities defining the steam injectivity and the effective heat transfer within the reservoir. The well design parameters are typically optimized with thermal reservoir simulators constructed considering that both injector and producer wells are parallel to themselves, to the formation boundaries...

... Abstract A mathematical model was proposed to predict production in rock by spontaneous imbibition. Heterogeneity of rock represented by fractal dimension was considered. This fractal model predicts a power law relationship between spontaneous imbibition rate and time. Experimental data...

... Abstract Shale gas and other unconventional gas plays have become an important factor in the United States energy market, and are often referred to as statistical plays due to their high heterogeneity. They present real engineering challenges for characterization and exploitation...
