Detection of effective porosity zones utilizing fractal modeling in an oilfield reservoir, NW Iran |
|
| چکیده انگلیسی مقاله |
An essential work for reservoir modeling specifically fractured reservoirs and development of oil and gas fields is the delineation of geological and geomechanical attributes such as rock type, e.g., effective porosity and permeability. The purpose of this investigation is delineation of effective porosity zones in an oilfield reservoir at the southern Iran for detection of fractured reservoir rocks. First, this parameter was estimated in 3D environment of the Asmari reservoir. Next, fractal number-size (N-S) and concentration-volume (C-V) models were utilized for categorization of the effective porosity zones. The C-V fractal model represents three effective porosity zones, and the N-S fractal analysis shows six zones with an index multifractal feature for the effective porosity data. The correlation between the results obtained by these fractal models presented that the obtained zones have a proper overlap together. High value porous zones based on these fractal models are commenced from 11% and 12.5%, respectively. Fractal modeling indicates that the porous zones happened in the SE and NW parts of the study oil field that presents the fractured part of the Asmari reservoir rock. Main faults from this oilfield are correlated with the porous zones derived via fractal modeling |
