... of water flooding methods, are the low piezoconductivity and high heterogeneity of a reservoir that leads to relatively high rates of decline in fluid production and, in particular, to long response productivity time for production wells to injection. In this paper, we consider a multi-criteria assessment...

... Abstract The structure and composition of oil reserves deteriorate in the course of a mature oil field development due to geological and technological factors. The geological factors include vertical and lateral macro-and micro-heterogeneity of the reservoirs under development. At the same time...

... Reservoir connectivity is an important parameter that represent heterogeneity level in the oil and gas formations. It affects such significant features of the reservoirs as sweep efficiency, recovery factor and well production rates. The various variants of models for one of the typical upper...

... Abstract As a rule, the basis for engineering calculations for monitoring the productivity of wells is the model of stationary and unsteady inflow in homogeneous formations or formations with a given type of zonal heterogeneity. This is due to the presence of analytical models for these cases...

... that full tensors are needed to accurately represent fluxes at Darcy scale then upscaling from core-scale measurements or simulations, or even if using geologic/geostatistical model (with spatial heterogeneous distribution of flow properties). More specifically, our upscaled Darcy scale model parameterized...

... parameter are not directly related with flow connectivity. Cluster proportion and net to gross ratio can be used with limitations for flow connectivity estimation when stochastic heterogeneity is low. The best estimation can be done by using neighbor reservoir parameter which correlation coefficient...

Synthetic materials are used to cast sheet-like, porous test specimens that have strongly-bonded layers with different mechanical properties. The layered specimen is placed between two thick...

... in characterizing formation heterogeneity and reveal pore structure type, a dielectric multi-frequency measurement is being utilized to measure the flushed zone oil saturation relatively independent of pore fluid salinity, rock texture, and composition. The comparative analysis of well-logging and well-test...

... and after polymer flooding show that the flow system dramatically changed. The connected volumes from injector to producer as well as the flow heterogeneity were influenced and substantial incremental oil produced. A number of tracer tests were performed in the pilot area of a polymer flood at various times...

... Abstract Typical wells in the Filanovskogo field are in a multi-zone reservoir with heterogeneous production flow profiles. The use of inflow control devices (ICD) in conjunction with zonal isolation packers, though successful, continues to evolve to improve overall ICD performance. However...

.... In our case, the use of continuous high-resolution thermophysical profiling on a full-size core allowed not only to depth match the core to the logging, to identify the optimal places to take core samples, to identify heterogeneities in the formation, but also to corrected the logging data to take...

However, at the present time, a significant number of deposits are in development, the productive layers of which were formed...

... The lithological and petrophysical model was tested by several well logging methods. The analyzed carbonate reservoirs were first differentiated by lithology due to high lithological heterogeneity. Then the criterion of textural heterogeneity was used to identify different reservoir classes...

In this case, the prediction of the properties can be based on the data obtained through direct sedimentation modelling, determining the relationship between the facial heterogeneity and filtration-volumetric characteristics of the reservoir.
