Paradigm shift in hydrocarbon exploration and development strategies has increased utilization of seismic data many fold for reservoir characterization. Complicated and nonlinear relationship between seismic attributes and reservoir properties has been addressed recently using artificial neural network techniques for lithofaices classification and prediction of reservoir properties through unsu...

fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...

1) Composition and quality of the in situ 2) Controls on distribution and volume of petroleum, both geographically and within a given borehole, 3) Water saturation and potential for internal or external water production, 4) Rock type and mineralogical composition for log calculations, lateral location and completion optimization, 5) Natural fracture distribution and porosity types, 6) Compartme...

The purpose of this study was to build small-scale genetic models of a reservoir by comparing the small and medium scale information derived from core analyses and well logs. The examined gas field is situated in the eastern part of the Pannonian Basin System. For the numerical solution several one (univariate) and multivariable (multivariate) statistical methods were used to describeone and mu...

this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

Field measurements of conductivity, porosity, etc. have shown their are high heterogeneity, the bounds of such heterogeneity increasing as the scale of observations changes. This has led to the development of fractal models, renormgroup methods, and methods of subgrid modeling. The subgrid modeling approach, associated with problems of the subsurface hydrodynamics, is presented. We consider a s...
