Among the recent technological breakthroughs that have revolutionized the search for oil and its production are innova-tions realized in the field of horizontal drilling. Once dormant, this practice is fast becoming routine ...

The Huizachal-Peregrina Anticlinorium is a large NNW-trending structure in the front ranges of the Sierra Madre Oriental of Mexico (23° 45ʹ N; 99° 10ʹ W). The breached core of the anticlinorium exposes three major geologic ...

Modem methods of seismic data analysis are tending to inversion through model fitting, i.e., actually finding the best model of the Earth's subsurface which would produce the amplitude and phase variation in the observed ...

The objective of this project is to develop a sandstone acidizing model that explicitly considers the flow geometry around perforations. The effect of diverting agent upon the acid injection along the perforation boundary ...

Molecular complexation properties of several types of size-selected ions are examined in the gas phase by mass spectrometric techniques. Transition metal oxide clusters of (MoO₃)[subscript n]⁻ where n = 2-12 and (WO₃)[subscript ...

The reservoir quality of sedimentary rocks is closely related to diagenesis, a process involving post-depositional alteration of freshly deposited sediments. Present-day rock properties such as porosity, permeability, ...

The modernization of Chinese culture has been a major feature of domestic policy since the Chinese Communist Party assumed political leadership in 1949. This modernization program has had profound effects upon indigenous ...

This study investigated the beliefs about language learning and use of language learning strategies by college EFL students in Taiwan. The relationship between learners' beliefs and strategy use was also studied. A total ...

A versatile, three-dimensional finite element front tracking model is developed for thermal recovery processes The model approximates the flow domain as regions of homogeneous fluid properties separated by a sharp front ...
