A numerical modelling and simulation of core-scale sandstone acidizing process: a study on the effect of temperature

Abstract: A wide and comprehensive understanding of the chemical reactions and mechanisms of HBF 4 is crucial as it significantly influences its performance in stimulating a sandstone formation. In general, it is well-known that HBF 4 is able to provide a deeper penetration into the sandstone matrix before being spent due to its uniquely slow hydrolysis ability to produce HF. In the present study, a 3D numerical modelling and simulation were conducted to examine the capability of HBF 4 in enhancing the porosity and perm… Show more

“…Acidizing is one of the common stimulation measures in oilfield, which means treating oil and gas reservoir with acidizing fluid to restore or increase the permeability of oil and gas reservoir and thus improve oil and gas recovery (Leong et al , 2018; Robert and Hill, 2019). At present, the most frequently used acidizing fluids are hydrochloric acid (12%–28% HCl) and soil acid (HCl + HF) solutions, etc., which usually come into contact with underground tubing and casing to accelerate the corrosion of these pipes.…”

“…Li et al [12] built a radial acidizing model and considered the effect of the temperature field on the reaction, but they did not consider the effect of the heterogeneities. Leong et al [13,14] did a modeling of the acidizing of HBF 4 in linear cores with COMSOL.…”
