“…Therefore, it is better to apply atomic dispersion as mode of injection/addition of the dispersed phase. This is because the droplet size of the dispersed phase should be as small as possible with respect to the application, and introducing the droplets in a mist form enhances the dispersion of the discrete phase. , For emulsions with a highly viscous oil, the influence of stirring speed and time must be considered, as these require a homogenizer for mixing just like large-volume emulsions and need sufficient energy and time to synthesize a stable emulsion. Since very minute solid particles are used as pickering agents, it is more feasible to use an ultrasonic bath/mixer/homogenizer to better disperse the pickering agent in the mixture to achieve maximum solubility in the colloid system.…”

Almost 60% of oil and 40% of gas reserves worldwide are contained in carbonate reservoirs where acidizing stimulation is more challenging compared to sandstone reservoirs. Utilization of emulsified acids in matrix acidizing operations has been the most effective technique for more than half a century. This is due to the colloidal system's ability to generate deep, narrow conduits toward production zones under controlled retarded reactivity with the rock surface, along with the excellent sweep efficiency and corrosion inhibition of the well equipment. This Review attempts to review the various kinds of emulsified acids that are used for matrix acidizing of carbonate formations. The Review is trying to trace the innovations that have, gradually, been applied for enhancing the performance of emulsified acids for a variety of conditions, their limitations, and the developmental solutions such hybrid emulsifiers and pickering emulsions. In addition, the Review also discusses the parameters, characteristics, and measuring techniques required for the successful synthesis of a stable and quality emulsion while considering the environmental concerns raised toward the application of an emulsified acid system. From the reviewed publications, it can be summarized that macroemulsions are best suited for matrix acidizing applications over microemulsions due to low emulsifier concentrations and high acid volume retention; similarly, water in oil emulsions provide better retardation in a comparison to oil in water emulsions. The small droplet size of the emulsion yields high viscosity and stability. The compositional balance between each component present in the acidizing system is a crucial factor for optimum performance. Moreover, for future practice, much focus is required to design emulsified acids as ecofriendly systems that can leave the least amount of toxicity during and after implementation.

“…During the past two years, we have conducted rigorous experimental probes to research the performance of emulsified acids produced via two common types of nonionic surfactant, namely, tweet 80 and Span 80. The performance evaluations were completed by way of experimental study of stability, rheological properties, and corrosivity. , Hence, in this work, we are willing to investigate the performance of the oil in water acidic emulsion formed by the cationic surfactant cetyltrimethylammonium bromide (CTAB). The behavior of the emulsion is studied to observe the rheological properties and stability of the emulsion in different conditions and concentrations of CTAB.…”

Cetyltrimethylammonium bromide (CTAB) surfactant was proven to be a reliable emulsifier for creating stable emulsions used for drilling, well stimulation, and EOR. The presence of acids like HCl during such operations may lead to the formation of acidic emulsions. No previous comprehensive investigations have been done to study the performance of CTAB-based acidic emulsions. This paper, therefore, presents experimental investigations of the stability, rheological behavior, and pH responsiveness of a CTAB/HCl-based acidic emulsion. The effects of temperature, pH, and CTAB concentration on the emulsion stability and rheology have been investigated using a bottle test and a TA Instrument DHR1 rheometer. Viscosity and flow sweep were analyzed for the steady state at a shear range of 2.5–250 s–1. For the dynamic tests, the storage modulus (G′) and loss modulus (G″) were observed by applying the oscillation test at the range of shear frequency from 0.1 to 100 rad/s. The results revealed that the emulsion exhibits steady rheological behaviors ranging from Newtonian to shear-dependent (psedosteady), depending on the temperature and CTAB concentration. The tendency of the emulsion to exhibit a solid-like behavior is also dependent on CTAB concentration, temperature, and pH. However, the pH responsiveness of the emulsion is more significantly observed within the acidic range of the pH.
