“…These polymers are used to fabricate asymmetric membranes, in which the selective and support layers are made of the same polymeric material. 54 The third class consists of low permeable highly cross-linked polymers such as polyaniline and polydicyclopentadiene membranes. These polymers are highly crosslinked, and membranes fabricated using these polymers are nanoporous when swelled in organic solvents.…”

Macroscopic, hollow thimbles were synthesized from dicyclopentadiene with the Grubbs second generation catalyst at a monomer:catalyst loading of 10,000:1. A series of Buchwald-Hartwig and Sonogashira coupling reactions were completed on the interior of the thimbles followed by extraction of the product to the exterior using hexane. In all examples, palladium was retained by the membranes at ≥99.9% levels. Both polar and apolar molecules with molecular weights from 101 to 583 g mol-1 permeated these thimbles with values for flux of 10-5 to 10-6 mol cm-2 h-1 , but selected molecules did not permeate them and had flux values 10 4 to 10 5 times slower. The difference in flux was large between molecules that permeated and those that did not permeate, but no trend was observed that correlated flux with molecular weight or hydrophobicity. Rather, molecules that did not permeate the membranes had large cross-sectional areas that led to low rates of diffusion within the highly cross-linked polydicyclopentadiene membranes. Membranes were fabricated from the ring opening metathesis polymerization of dicyclopentadiene with the Grubbs first generation catalyst at a monomer:catalyst loading of 5,000:1. Mixtures of fatty acid salts were separated using polydicyclopentadiene membranes. Mixtures of fatty acids could not be separated by the membranes, but when triisobutylamine was added to the fatty acids, cis-fatty acid salts had slower permeation though the membranes than saturated and trans-fatty acid salts. Oleic, petroselinic, vaccenic, linoleic, and linolenic acid salts with triisobutylamine had slower permeation relative to the permeation of stearic and elaidic acid salts. Organic catalysts were retained from organic molecules using nanoporous polydicyclopentadiene membranes. Acid or base was added to organic catalysts that increased the critical areas of the organic catalysts to the size range (>0.5 nm 2) where PDCPD membranes could retain them. The catalysts by themselves were too small to be v TABLE OF CONTENTS LIST OF TABLES ……………………………………………………………………….ix LIST OF FIGURES .

Considered is application of passive seismic monitoring technology SLEC (Seismic Location of Emission Centers) to survey the heterogeneity of oil saturation of reservoir in one of the fields of Orenburg region (Volga-Ural area, Russia). Presented is a brief description of SLEC technology designed for surface-based passive monitoring of seismic emission of geological formations and estimation of characteristics of reservoirs, particularly, reservoir fluid saturation type. Among benefits of SLEC technology are its surface based observation system and the use of Slionkin Focusing Transformation algorithms allowing to focus SLEC locator to any points of a geological formation (within the range of a few kilometers), thus allowing distinguish between useful and interference sources of emission signals. Presented are results of long-term SLEC monitoring. A comparison of SLEC processing results map of oil saturation index versus production data acquired in operating wells and well test data supports the reliability of SLEC-based maps of reservoir oil saturation heterogeneity. These heterogeneity maps can be used to improve the efficiency of oil production and for post-exploration of the field.
