Well Spacing Optimization for Tight Sandstone Gas Reservoir

Proceedings of International Oil and Gas Conference and Exhibition in China, 2010
Abstract In the past five years, tight sandstone gas reserves amounted to almost 50% of the newly proved natural gas reserves of PetroChina Co., Ltd. and will be one of the main targets of natural gas production for a long term. Means to determine the reasonable well spacing are the key topics in the development of tight ...

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

AAPG Bulletin, 2014
Abstract 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

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 ...

Effect of CO2 Content on the Natural Gas Production from Tight Gas Sandstone Reservoirs

SPE Middle East Oil & Gas Show and Conference, 2017
Abstract The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas desorption from the rock surface to the pore body. All the existing models did not consider the effect of CO2

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 ...

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.
