Acidizing Treatments for Tight Gas Sandstone Reservoirs

International Petroleum Technology Conference, 2009
This reference is for an abstract only. A full paper was not submitted for this conference. Abstract Stimulation of tight gas sandstone reservoirs is a challenge due to many variables contributed into acidizing efficiency such acids type, concentration, volume, stages, injection rate, reservoir ...

Pore structure and reservoir physical properties for effective development of tight sandstone gas: A case study from the Central Sichuan Basin, China

Geological Journal, 2022
Several large gas fields have been found in the Central Sichuan Basin in recent years, with proven reserves of more than 100 × 10 9 m3. Among these, the tight sandstone gas in the Late Triassic Xujiahe Formation is a key target in the Sichuan Basin.

Multisynchrosqueezing Generalized S-Transform and Its Application in Tight Sandstone Gas Reservoir Identification

IEEE Geoscience and Remote Sensing Letters, 2022
Synchrosqueezing transform (SST) is a high-resolution time-frequency (TF) analysis (TFA) approach for seismic spectral anomaly detection. Here, a novel method called multisynchrosqueezing generalized S-transform (GST) is proposed and applied for the ...

Gas recovery potential of sandstones from tight gas reservoirs

International Journal of Rock Mechanics and Mining Sciences, 2014
Abstract The aim of our experimental study is to characterize experimentally the petro-physical properties of a set of sandstones originating from different depths from a single tight gas field, in order to improve our knowledge on their gas recovery potential. The initial characterization of these sandstones is performed in the dry state, and in the

Microcrack Permeability in Tight Gas Sandstone

Society of Petroleum Engineers Journal, 1983
Abstract A model of stress-dependent permeability was developed on the basis of flow through cracks. The compliance of the cracks is controlled by elastic deformation of a Gaussian distribution of surface asperities, indented into the opposing crack face.

Experimental study on critical sand production pressure gradient at different production stages of high temperature and high pressure tight sandstone gas reservoir

Energy Storage
Sand production is a common issue in sandstone gas reservoir development, severely impacting the productivity of sandstone gas wells. In order to thoroughly investigate the sand production characteristics of high‐temperature and high‐pressure tight ...

Acidizing flowback optimization for tight sandstone gas reservoirs

Journal of Natural Gas Science and Engineering, 2015
Abstract The physical properties of Sichuan tight sandstone formations include low porosity and low permeability. Fortunately, micro-fractures are well developed in this area, and the development of a reservoir is thus possible. Acidification can repair reservoir damage and improve single-well production; however, gas well production can change after

Pervasive Tight-gas Sandstone Reservoirs: An Overview

2008
The objectives of this chapter are threefold: (1) to provide a historical perspective on considerations of pervasive tight-gas accumulations, (2) to provide some observations on the present understanding of these accumulations, and (3) to anticipate where the industry is headed in the future.

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
