Abstract Chlorite, an Fe-and Mg-rich aluminosilicate clay, may be either detrital or authigenic
in sandstones. Detrital chlorite includes mineral grains, components of lithic grain, matrix …

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 …

Porosity and permeability generally decrease with increasing depth (thermal exposure and
effective pressure); however, a significant number of deep (> 4 km [approximately 13,000 ft]) …

Models and concepts of sandstone diagenesis developed over the past two decades are
currently employed with variable success to predict Previous Hit reservoir Next Hit quality in …

The spatial and temporal distribution of diagenetic alterations in siliciclastic sequences is
controlled by a complex array of interrelated parameters that prevail during eodiagenesis …

This paper addresses the origin, distribution pattern and burial diagenetic evolution of clay
minerals in sandstone: kaolin, smectite, illite, chlorite, berthierine, glauconite and mixed …

Plots are presented comparing average porosity vs. depth for 30,122 siliciclastic petroleum
reservoirs and 10,481 carbonate petroleum reservoirs covering all petroleum-producing …

The microstructure and petrophysical properties of fault rocks from siliciclastic hydrocarbon
reservoirs of the North Sea are closely related to the effective stress, temperature and …

Tight gas reservoirs have become popular targets in petroleum exploration in recent years,
due largely to the increasing market demand for gas and also to technology advances used …

Fault-zone composition, estimated using the shale gouge ratio (SGR) algorithm, can be
empirically calibrated with pressure data to define depth-dependent seal-failure envelopes …
