Reservoir rocks are hollow below the surface that capable of storing and flowing groundwater can be utilized by community. The limestone facies is a good reservoir rock. characteristics in Ombulo Region, Gorontalo Regency, which reach 3.42 km2, very interesting to study. This study aims analyze porosity value each area. research method used consisted field geological surveys petrographic labora...

the reservoir’s diff erential pressure. Most samples are initially humidifi ed to avoid the softening matrix eff ect of initial introduction of moisture in the pore space. Small amounts of water (less than 1% of the pore volume) can reduce the bulk and shear moduli of the rock signifi cantly. Th e data in this paper are the estimated mean properties (markers in the plots) and one standard devia...

differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. a numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. reservoir is modeled using the eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. dynamic equilibr...

We used a Hierarchical Neuro-Fuzzy Class Method based on binary space partitioning NFHBClass Method for macroscopic rock texture classification. The relevance of this study is in helping Geologists in the diagnosis and planning of oil reservoir exploration. The proposed method is capable of generating its own decision structure, with automatic extraction of fuzzy rules. These rules are linguist...

Advanced seismic techniques such as prestack inversion or azimuthal analysis are now routinely adopted for quantitative reservoir characterization of rock properties and fracture indicators, however the quality of the input seismic data is critical to such advanced analyses. Frequency content, random and coherent noise, amplitude-preserving processing and gather flatness must be addressed at th...

Bibi Hakimeh oilfield consists of more than 145 oil producing wells. Its Oligomiocene Asmari reservoir is dominantly made of limestone. The act of a reverse fault on the north flank of Bibi-Hakimeh Field caused a significant thickness reduction in Gachsaran formation in the way that in some drilled wells, members No. 2, 3, 4, 5 and 6 of Gachsaran cap rock have been totally eliminated. This caus...
