The tight sandstones are characterized by low porosity, low permeability, complex pore
structure and strong heterogeneity due to the extensive diagenetic modifications they …

Diagenesis exerts a strong control on the quality and heterogeneity of most clastic
reservoirs. Variations in the distribution of diagenetic alterations usually accentuate the …

The deep high-temperature, high-pressure Lower Cretaceous Bashijiqike sandstone (buried
to depths as great as 6.5–7.1 km [21,325–23,293 ft]) is an important natural gas reservoir in …

Reservoir quality is a critical risk factor in deep to ultradeep reservoirs at depths> 4.5 km.
Analysis of Paleogene Wilcox sandstones on the upper Texas Gulf Coast provides insight …

Northeastern Egypt is one of the most important exposures in the Middle East and North
Africa to study Jurassic facies. The present study analyzes 130 thin sections from a …

Abstract The Nile Delta has become an economically important region of Egypt, because of
large-scale natural gas and oil discoveries in recent decades. The offshore Baltim East field …

Tertiary, syn-rift clastic reservoirs offer a unique opportunity to investigate the pivotal role of
depositional and early diagenetic controls on reservoir quality. The Al Wajh Formation is a …

Fluvio-deltaic strata host significant volumes of hydrocarbons in different basins across the
world, and are characterized by depositional heterogeneities and varying diagenetic …

An integrated analysis of the petrographic characteristics and types and distribution of
diagenetic alteration in the upper Paleozoic Benxi–Taiyuan, Shanxi, and **ashihezi …

The Forties Sandstone Member is an important deep-water reservoir in the Central North
Sea. The role of depositional characteristics, grain-coating clays, and diagenesis in …
