Matrix acidizing is a common technique for carbonate reservoir stimulation. In this work, a
new two-scale continuum model is developed to study the 2D acidizing process. The Navier …

The temperature has a significant impact on acid stimulation efficiency in carbonate
reservoirs. To fully understand its effect, this study utilizes a two-scale continuum model …

Acidic fluid flow in geologic formations leads to mineral dissolution and, under certain
circumstances, to localized dissolution forming a dendritic pattern, known as wormhole …

In carbonate matrix acidizing, the critical design parameters are interstitial velocity and pore
volume to breakthrough for wormhole propagation at the optimal condition (vi, opt and …

Acidization is a widely used stimulation technique for carbonate reservoirs aimed at
removing formation damage, and if successful, can result in the creation of wormholes of …

It was recently shown that anisotropic wormhole networks might arise from the acidizing of
anisotropic carbonates. In openhole or cased and densely perforated completions, where in …

As acidic fluids flow and dissolve minerals in carbonate formations, the reaction may localize
into a dendritic pattern under certain conditions known as wormhole. Wormhole is …

The permeability in carbonate reservoirs is not the same in all directions (ie, anisotropic), a
property seldom considered in acid stimulation. The study hypothesizes that permeability …

Most numerical simulations for modeling acid reactive fluid transport and wormhole
propagation during matrix acidizing, waterflooding, and CO2 sequestration in carbonate …

Natural fractures and wormholes strongly influence the performance of acid fracturing in
naturally fractured carbonate reservoirs. This work uses an integrated model to study the …
