Assessment of Seal Integrity and Dynamic Fault Character Using Hydrocarbon Geochemistry and PVT Analysis: Examples from the Middle East
Understanding the genesis and relationships among oil and gas accumulations is of prime importance in exploration and development programs. This will not only help better identify and delineate petroleum systems, but also aid in evaluating seals – one of the most critical elements in petroleum systems. Integrating geochemistry and pressure-volume-temperature (PVT) data of reservoir fluids offer tools for the assessment of fault and top seal integrity. Examples from fields at different levels of delineation, development and management from different Paleozoic and Mesozoic basins in the Middle East are discussed to demonstrate the role of fluid geochemistry in aiding the evaluation of top, lateral and fault seal integrity, and in providing insights into the sealing and buffering effects of reservoir heterogeneity on hydrocarbon fluid flow. Examples discussed include (1) detection of petrophysical sealing using PVT fluid composition data, (2) geochemical detection of partial sealing, (3) the development of top seal by solid reservoir bitumen immediately below a regional unconformity, (4) geochemical recognition of possible strike-slip fault seal, and (5) geochemical detection of fault-controlled reservoir compartmentalisation in a field at an appraisal stage where PVT data are limited or inconclusive.

期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
