A New Method For The Rapid Calculation Of Finely-Gridded Reservoir Simulation Pressures, Benjamin Arik Hardy Nov 2005

A New Method For The Rapid Calculation Of Finely-Gridded Reservoir Simulation Pressures, Benjamin Arik Hardy

Theses and Dissertations

A new method for the determination of finely-gridded reservoir simulation pressures has been developed. It is estimated to be as much as hundreds to thousands of times faster than other methods for very large reservoir simulation grids. The method extends the work of Weber et al. Weber demonstrated accuracies for the pressure solution normally requiring millions of cells using traditional finite-difference equations with only hundreds of cells. This was accomplished through the use of finite-difference equations that incorporate the physics of the flow. Although these coarse-grid solutions achieve accuracies normally requiring orders of magnitude more resolution, their coarse resolution does …

Generating Data-Extraction Ontologies By Example, Yuanqiu Zhou Nov 2005

Generating Data-Extraction Ontologies By Example, Yuanqiu Zhou

Theses and Dissertations

Ontology-based data-extraction is a resilient web data-extraction approach. A major limitation of this approach is that ontology experts must manually develop and maintain data-extraction ontologies. The limitation prevents ordinary users who have little knowledge of conceptual models from making use of this resilient approach. In this thesis we have designed and implemented a general framework, OntoByE, to generate data-extraction ontologies semi-automatically through a small set of examples collected by users. With the assistance of a limited amount of prior knowledge, experimental evidence shows that OntoByE is capable of interacting with users to generate data-extraction ontologies for domains of interest to …
