Injection of acidic formulations into a carbonate reservoir is commonly used in the oil
industry to enhance or restore well productivity. The purpose of this method is to create …

Acid fracturing is applied to increase the productivity of carbonate formations. The acid
creates rough fracture surfaces and channels that keep the fractures open after closure. This …

Emulsified acid has attracted considerable attention of the oil and gas industry due to its
delayed action that allows deeper penetration of acid into the formation which essentially …

Understanding the relationship among the individual factors (ie, carbonate rock types, acid
rock reaction kinetics, deterioration of rock mechanical properties) can provide practical …

Comprehensive studies on wormhole prediction models have been performed to design
successful matrix acidizing in carbonate reservoirs. In particular, linear coreflooding …

One of the methods to improve carbonate formation productivity is acid fracturing. The acid
injection creates dissolution along the fracture, which improves fracture conductivity. This …

Abstract The Sichuan Basin's carbonate gas reservoirs require stimulation. Non-uniform
etched fractures are created as a result of the violent interaction between reservoir cores …

This study aims to investigate the propagation characteristics of an optimum wormhole to
make an efficient acid treatment in carbonate matrix acidizing based on wormhole …

For successful emulsified acid treatment, it is imperative to have emulsified acid that can
maintain a water-in-oil emulsion state for 24 h at room temperature and 4 h at high …

With the further application of aerobic granular sludge (AGS), the granules specific
morphological and structural assessment is more essential. Full-size AGS was evaluated …
