The Circum-Gulf of Mexico and the Caribbean


Book Description

"AAPG Memoir 79, The Circum-Gulf of Mexico and the Caribbean, is the first volume in more than a decade to document such a wide range of research on the geology of this vast area. Of the total 44 papers, roughly two-thirds pertain to the Gulf of Mexico, with an emphasis on the Mexican portion of the basin, and to the petroliferous areas of the southern Caribbean, including Colombia, Venezuela, Cuba, and Trinidad and Tobago. The remaining papers relate to the Antilles and Central America, as well as a series of papers that address region-wide topics such as plate tectonic evolution. A significant number of papers were contributed by authors from national oil companies and universities from within the region." --AAPG.







Carbonate Reservoir Characterization: A Geologic-Engineering Analysis, Part II


Book Description

This second volume on carbonate reservoirs completes the two-volume treatise on this important topic for petroleum engineers and geologists. Together, the volumes form a complete, modern reference to the properties and production behaviour of carbonate petroleum reservoirs.The book contains valuable glossaries to geologic and petroleum engineering terms providing exact definitions for writers and speakers. Lecturers will find a useful appendix devoted to questions and problems that can be used for teaching assignments as well as a guide for lecture development. In addition, there is a chapter devoted to core analysis of carbonate rocks which is ideal for laboratory instruction.Managers and production engineers will find a review of the latest laboratory technology for carbonate formation evaluation in the chapter on core analysis. The modern classification of carbonate rocks is presented with petroleum production performance and overall characterization using seismic and well test analyses. Separate chapters are devoted to the important naturally fractured and chalk reservoirs.Throughout the book, the emphasis is on formation evaluation and performance.This two-volume work brings together the wide variety of approaches to the study of carbonate reservoirs and will therefore be of value to managers, engineers, geologists and lecturers.




Depositional Systems


Book Description

"Offering a solid introduction to the principles and applications of sedimentology and stratigraphy, author Richard A. Davis Jr. emphasizes the integration of these two areas and covers both modern and ancient depositional environments using modern examples and excellent illustrations. The Second Edition presents updated technical information, and offers a major reorganization of chapters to promote greater clarity and to place greater emphasis on more current topics. Additional content highlights: provides new approaches to basic analysis, including sequence stratigraphy; integrates genetically related depositional environments that share a common thread in concurrent chapters; discusses topics such as sedimentary processes and structures, the desert system, the fluvial system, the delta system, the barrier island system, reefs and the carbonate platform system, the deep ocean system, and much more." --




Carbonate Reservoirs


Book Description

The porosity of carbonates as compared to sandstones is vastly more complex with simple intergrain porosity dominates sandstones while carbonates commonly exhibit complex secondary pore systems that may evolve during burial. Initial porosity of carbonates is much greater than that seen in sandstones due to common intragranular porosity. Fractures, both natural and induced, are much more important in carbonates. Diagenesis is a major factor in the development of ultimate pore systems in carbonates. The geologically based Choquette–Pray carbonate porosity classification is the most commonly used scheme. Their 15 different pore types are based on fabric selectivity. A major feature of the classification is its recognition of the potential of porosity evolution through time and burial. Three porosity development zones are recognized: eogenetic, dealing with surface processes; mesogenetic, dealing with burial processes; and telogenetic, exhumed rocks dealing again with surface processes. This classification is best used during exploration, while other engineering-based classifications such as the one developed by Lucia should be used in reservoir characterization and as input for reservoir modeling. Examples of all 15 pore types are given.
