The phrase "acid fluid" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing substances that are acidic in nature, such as certain chemicals or bodily fluids.
Example: "The laboratory analysis revealed that the sample contained a highly corrosive acid fluid that required careful handling."
Alternatives: "acidic solution" or "corrosive liquid".
Analysis of this unique oil shows that it is a waxy secretion of the proventriculus (the first chamber of the stomach), rich in vitamins A and D. In most birds the walls of the proventriculus produce an acid fluid that rapidly breaks down raw food entering from the esophagus.
Large amount of acid fluid was brought into the reservoir due to the hydrocarbon generation of the mature of organic matters which had dissolved the soluble components.
Both Domelon et al. (1992) and Xiong and Holditch (1994) introduced robust rule-based systems for acid fluid selection that are damage-type specific, and depend primarily on the formation mineralogy and the produced fluid composition.
The better the sediment particle sorting is, and the lower the shale content is, the more the intergranular porosity can be maintained, to provide a channel for the migration of acid fluid in a later period.
In all of these systems, however, the acid fluid selection follows guidelines that do not reflect the recent technological advances in acidizing blends formulations, such as phosphonic acid blends and acid chelating blends.
In middle diagenetic stage A, a large amount of intragranular dissolved pores and intergranular dissolved pores are developed due to the dissolution of feldspar and volcanic rock fragments caused by the erosion of organic acid and inorganic acid fluid originated from the maturation of organic matter.
The initial viscosity of the acid fluids was low.
Overall, the interaction with acid fluids causes a severe mineralogical alteration of the cement and the development of a carbonated, low-porosity layer near the reservoir interface.
SDVA acid is one kind of In Situ Self-Diverting acid fluids that are widely used for diverting acid into a low-permeability zone in carbonate reservoir treatment, thus stimulating the production of the heterogeneous reservoir effectively.
Acid fluids in volcanic-hydrothermal systems dissolve volcanic host rocks.
The upper part most likely represents clayey sediments containing hydrothermal acid fluids, whereas the lower part is probably associated with the presence of rather resistive volcanic gases.
