Abstract
The study investigated the impact of ion composition in technological fluids on the re-agglomeration of hydraulic fracturing (HF) fluids after their destruction. The findings underscored the importance of considering "re-agglomeration" during the planning and execution of HF operations, as well as the necessity of conducting compatibility studies on the fluids. Experimental observations revealed that kill fluids based on mineralized water exhibited a reduction in dynamic viscosity when HF fluids were added. However, the addition of specific components posed a risk of re-agglomeration, particularly in wells with high corrosion rates. Further investigations involving higher concentrations of trivalent iron ions are warranted to assess these risks under such conditions.
