Effect of pore structure on the producibility of tight-gas sandstones

AAPG Bulletin, 2014
The estimated ultimate recovery (EUR) is one of the most significant properties of tight-gas sandstone reservoirs, but it remains difficult to predict. Estimated ultimate recovery is dependent on the success of stimulation by hydraulic fracturing, the existence and connectivity of natural fractures, and as illustrated in this article, the pore ...

Imaging tight gas sandstones in the East Texas Basin

First Break, 2008
Low porosity (tight) gas sands contain important commercial reserves but, unfortunately, are difficult to image seismically with the quality needed to drive an effective drilling programme. These reservoirs typically have a small contrast in acoustic impedance relative to the encasing shales which results in a subtle seismic signature.

Acoustic measures of partial gas saturation in tight sandstones

Journal of Geophysical Research: Solid Earth, 1984
The acoustic properties of tight sandstones are very sensitive to partial gas/water saturation. Measurements at 5 kHz show that compressional velocity drops sharply with undersaturation. Extensional and shear losses at 5 kHz are large in both fully and partially saturated sands. The shear loss Qs−1 declines linearly with increasing gas content.

Wavelet Transform for Fracture Diagnostics in Tight Gas Sandstone

SPE Conference at Oman Petroleum & Energy Show
Abstract Accurately determining fracture closure pressure is essential for optimizing hydraulic fracture treatments in gas reservoirs, especially in tight sandstone formations with low permeability. Traditional methods, like the G-function, estimate closure pressure from pressure decline during flowback, but they often rely on ...

Dynamic Instability Characteristics of Sandstone-Mudstone Combinations During Gas Drilling in Tight Sandstone Gas Reservoirs

SPE Journal
Summary Gas drilling utilizes compressed nitrogen rather than mud as the drilling fluid to fundamentally eliminate reservoir damage, making it a highly promising technology for tight sandstone gas reservoir development. However, wellbore instability remains a significant challenge, particularly in interbedded sandstone-mudstone ...

Reservoir Properties and Gas Productivity of the Corcoran and Cozzette Tight Sandstones, Colorado

Proceedings of SPE/DOE Low Permeability Gas Reservoirs Symposium, 1985
Abstract The Upper Cretaceous Corcoran and Cozzette Sandstones are fine to very fine grained blanket-geometry, low-permeability barrier and strandplain sandstones that trend northeast across the southern Piceance Creek Basin of Colorado. Development of these tight gas Piceance Creek Basin of Colorado. Development of
