Effect of Chelating Agents on Tight Sandstone Formation Mineralogy During Sandstone Acidizing
Petrophysics – The SPWLA Journal of Formation Evaluation and Reservoir Description, 2023Dissolution of the wellbore damage is the main target of sandstone acidizing. The presence of minerals like clays, feldspar, zeolites, and alumino-silicates makes acidizing a challenging task because they may form undesired products (precipitates) when reacted with mud acid.

3D Tight Sandstone Digital Rock Reconstruction with Deep Learning
Journal of Petroleum Science and Engineering, 2021Tight oil and gas reservoirs have attracted many attentions and are one of the hottest research fields in recent years. Tight sandstones have complex pore structures and narrow pores and throats with pore sizes varying from nanometers to micrometers, studying flow mechanisms in tight sandstones is of significance to tight oil/gas reservoir development.

Fluid Flow Modeling in Tight Carboniferous Sandstone
Proceedings, 2013Permeability of rock samples was the object of analysis. In the standard approach permeability values are determined from the laboratory measurements using permeameters. There are distinct limitations for used equipment for such measurements. In the presented case rock permeability was calculated by Computational Fluid Dynamics (CFD).

A study on effective medium theories in tight sandstone
Global Meeting Abstracts, 2011The tight sandstone gas reservoirs in the central Sichuan basin are characterized by wide distribution and low abundance. Sandstone samples from this area usually have low porosity and poor connectivity. This paper analyzes the laboratory data of tight sandstone samples with four different inclusion models based on effective medium theory and compares ...

Acidizing Treatments for Tight Gas Sandstone Reservoirs
International Petroleum Technology Conference, 2009This 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 ...

Pervasive Tight-gas Sandstone Reservoirs: An Overview
2008The 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.

Rock-Fluid Interactions in a Tight Sandstone Reservoir
Volume 8: Offshore Geotechnics; Petroleum TechnologyAbstract In this work, we present a comprehensive and practical framework to quantify the dynamic characteristics of pore-throat structure together with wettability alterations during a waterflooding process in a tight sandstone reservoir in addition to evaluating the impact of ionic composition and salinity on its performance.
