The hydric resource coming from groundwater has a strategic nature at global scale, within context of overpopulation and over exploitation the climate change. Chile doesn’t scape to it, where models predict drought for most country, including partially, agriculture region Central Valley between Santiago Puerto Montt. adaption process change demands exploration new sources provisions this resour...

The main subject of the research reported in this paper is to understand how the complexity of the earth’s subsurface is transferred to the wavefield. It will be shown that the apparent complexity can be captured by means of a scaling medium representation. In this multiscale representation the Hölder exponents and the singularity spectrum constitute useful order of magnitude estimates mathemat...

Gas storage and flow behavior in the shale gas rocks are complex and hard to identify by conventional core analysis. This study integrates clustering analysis techniques from material science, petrophysics, and petrology to characterize North American shale gas samples from Utica, Haynesville, and Fayetteville shale gas plays. High pressure (up to 60,000 psi) mercury porosimetry analysis (MICP)...

The Middle Jurassic Brent Group sediments and their correlatives on the Norwegian shelf are, in economic terms, the most important hydrocarbon reservoir in NW Europe. In 1971 the Brent Field was discovered by Shell/Esso and tested in 1972 with 1.8 billion barrels of recoverable oil; nine major Brent sandstone fields were discovered by the end of 1973 (Brennand et al. 1990). In 1980 the northern...

Триасовые отложения Скифско-Туранской платформы, с которыми связаны основные перспективы открытия новых скоплений углеводородов, претерпели значительные постседиментационные преобразования. Их результатом явилась существенная утрата осадочными породами первичных емкостно-фильтрационных свойств. Современные коллекторы, содержащие скопления нефти и газа, имеют, как правило, эпигенетичный характер...

The aim of the study is to condition stochastic generated realizations on well test data in order to improve simulation of facies and petrophysics in fluvial reservoirs. First we have used the pressure data to estimate the shortest distance from the well to a possible channel boundary and thereby simulate the channel structures. The well test also provides the permeability average in the part o...

The major results of research in the United States for 1971-1974 in the areas of static, high-pressure X ray, ultrasonic and shock wave measurements, and progress in theoretical equations of state are summarized. This 4-year period has seen the massive accumulation of new data pertinent to describing the properties, and to some extent geodynamic processes, of the upper mantle as well as exposin...

In this paper, we present a combined geological, geophysical and rock mechanics approach to natural fractured reservoir characterization. The local structure entropy analysis on 3D seismic data is used to detect distributions of fault and subfault systems. The curvature attribute along with modeled strain and stress field, constrained with the log data measuring Pand S-wave velocities and rock ...

The use of Artificial Neural Network (ANN) especially Backpropagation Neural Network (BPNN) has been a promising tool for well log analysis in predicting permeability. However, due to the range of permeability data, it is normally converted using logarithmic transform before being used for data analysis by the BPNN. This has an impact on the accuracy of the permeability prediction. This paper s...
