Chapter 14 Chemical Composition of Asphalt as Related to Asphalt Durability

Abstract: Publisher Summary This chapter examines the literature dealing with the chemical composition of asphalt and changes in composition during environmental aging that affect durability-related properties. The characterization of the chemical functional types gives a fundamental approach to the relationships between asphalt composition and asphalt properties, and the performance of asphalts and asphalt-aggregate mixtures. Differences in the quality of asphalts depend on their crude oil sources because different crude oils have different chemical compositions. A durable asphalt is defined as one that (a) possesses the physical properties necessary to produce the desired initial product performance properties, and (b) is resistant to changes in physical properties during long-term, in-service environmental aging. Durability is determined by the physical properties of the asphalt, which are determined directly by chemical composition.

Chapter 3 Geological aspects of petroleum related rock mechanics

Abstract: Publisher Summary The purpose of this chapter is to give an introduction to geological aspects, which are of particular importance in petroleum related rock mechanics. The present state of a rock and its present mechanical properties are of interest. A sedimentary basin may be exposed to sedimentary subsidence, sea-level changes and tectonic forces creating repeated cycles of elevation and depression, in addition to erosion, changes in sedimentary environment, changes in sedimentation rate, solution and precipitation of cementing material etc. All these effects will complicate the geological description of the sedimentary basin. These geological activities and events will affect not only current rock mechanical properties, but also current boundary conditions in terms of in situ stresses and pore pressure. Therefore, knowledge of geological processes is valuable in rock engineering. Although on a totally different time scale and length scale, geological processes are often comparable with events in rock mechanics laboratory testing, which means that such tests may be used to enhance our understanding of geological phenomena.

Mining and fusion of petroleum data with fuzzy logic and neural network agents

Abstract: Analyzing data from well logs and seismic is often a complex and laborious process because a physical relationship cannot be established to show how the data are correlated. In this study, we will develop the next generation of 'intelligent' software that will identify the nonlinear relationship and mapping between well logs/rock properties and seismic information and extract rock properties, relevant reservoir information, and rules (knowledge) from these databases. The software will use fuzzy logic techniques because the data and our requirements are imperfect. In addition, it will use neural network techniques, since the functional structure of the data is unknown. In particular, the software will be used to group data into important data sets; extract and classify dominant and interesting patterns that exist between these data sets; discover secondary, tertiary and higher-order data patterns; and discover expected and unexpected structural relationships between data sets.
