“…Some older models of sandstone diagenesis invoked large-scale water flow systems as the main controls on reservoir quality (Giles et al 2000); these tended to assume relatively open geochemical systems. Some invoked a vital role for organic acids derived from source rocks (e.g.…”

Abstract:The porosity and permeability of sandstone and carbonate reservoirs (known as reservoir quality) are essential inputs for successful oil and gas resource exploration and exploitation. This chapter introduces basic concepts, analytical and modelling techniques and some of the key controversies to be discussed in 20 research papers that were initially presented at a Geological Society conference in 2014 titled 'Reservoir Quality of Clastic and Carbonate Rocks: Analysis, Modelling and Prediction'. Reservoir quality in both sandstones and carbonates is studied using a wide range of techniques: log analysis and petrophysical core analysis, core description, routine petrographic tools and, ideally, less routine techniques such as stable isotope analysis, fluid inclusion analysis and other geochemical approaches. Sandstone and carbonate reservoirs both benefit from the study of modern analogues to constrain the primary character of sediment before they become a hydrocarbon reservoir. Prediction of sandstone and carbonate reservoir properties also benefits from running constrained experiments to simulate diagenetic processes during burial, compaction and heating. There are many common controls on sandstone and carbonate reservoir quality, including environment of deposition, rate of deposition and rate and magnitude of sea-level change, and many eogenetic processes. Compactional and mesogenetic processes tend to affect sandstone and carbonate somewhat differently but are both influenced by rate of burial, and the thermal and pressure history of a basin. Key differences in sandstone and carbonate reservoir quality include the specific influence of stratigraphic age on seawater composition (calcite v. aragonite oceans), the greater role of compaction in sandstones and the greater reactivity and geochemical openness of carbonate systems. Some of the key controversies in sandstone and carbonate reservoir quality focus on the role of petroleum emplacement on diagenesis and porosity loss, the role of effective stress in chemical compaction (pressure solution) and the degree of geochemical openness of reservoirs during diagenesis and cementation. This collection of papers contains case study-based examples of sandstone and carbonate reservoir quality prediction as well as modern analogue, outcrop analogue, modelling and advanced analytical approaches.Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.Porosity and permeability (reservoir quality) exert fundamental controls on the economic viability of a petroleum accumulation (Blackbourn 2012).They need to be quantified from basin access and exploration, via appraisal and field development through secondary and tertiary recovery in order to

“…Whilst this may apply to samples from very nearsource rock provenances, it would also require that the material derived from very discrete and homogeneous sedimentary layers. In part mitigation of this assumption, the scenario can exist where the diagenetic severity imparted upon a large area of sediment is uniform and the resultant diagenetic textures found on the quartz sand grains from the sample are therefore homogeneous throughout the sedimentary strata concerned [26].…”

The analyses of 738 soil and sediment samples taken during the investigation of 20 forensic cases are combined in a database for retrospective comparisons. Quartz sand grain surface textures are combined into grain types which are analysed at one of five orders of classification. This classification also provides frequency data on the number of grain types found in a sample, the individuality of the quartz grain type assemblages and quartz grain type ratios. The technique, developed primarily as an exclusion mechanism, suggests possibilities, in some circumstances, that significant interpretations can be achieved at different orders of classification. The technique provides excellent exclusionary results and, when combined with other independent lines of analysis, is a powerful tool in forensic interpretation because it uses quartz as its discriminatory mineral. The technique also highlights the potential for computer image recognition analysis.Se combinan en una base de datos, con fines de comparación retrospectiva, los análisis de 738 muestras de suelo y sedimentos tomados en la investigación de 20 casos forenses. Las texturas de superficies de arena con granos de cuarzo se combinan en tipos de grano que son analizadas como una de cinco órdenes de clasificación. Esta clasificación también prove e datos de frecuencia de los tipos de grano encontrados en una muestra, la individualidad de ensamblajes de los tipos de grano de cuarzo y los cocientes de los tipos de grano de cuarzo. La técnica, desarrollada en un principio como un mecanismo de exclusión, sugiere posibilidades en algunas circunstancias de que se pueden conseguir interpretaciones significativas en distintos órdenes de clasificación. La técnica provee resultados de exclusión excelentes y , cuando se combina con otras líneas independientes de análisis es una herramienta poderosa en interpretación forense ya que utiliza el cuarzo como mineral discriminatorio. La técnica también ensalza el potencial del análisis mediante imagen computerizada.

“…Quartz cementation is the main cause of porosity loss in the Brae Formation sandstone reservoirs of the Miller and Kingfisher Fields (Giles et al, 2000;Marchand et al, 2000Marchand et al, , 2002. The precipitation of quartz overgrowths in many sedimentary basins commonly occurs during deep burial diagenesis (>2.5 km) at elevated temperatures, typically 70 -130 jC (e.g.…”
