Abstract

The study is concerned with the composition of oil-free hydrophobic emulsion designed for multiple purposes, particularly for well stimulation. The study is aimed at formulation of oil-free hydrophobic emulsion composition with desired physical and chemical, rheological, structural-mechanical, and process parameters and properties required for diversion of acid compositions during matrix, selective and deep-penetrating acid treatments of near-wellbore zones in carbonate reservoirs. The authors review microscopic studies of oil-free hydrophobic emulsions with concentration of dispersed phase of 80% and higher based on state-of-the-art emulsifiers (hydrocarbon surfactant solutions). Analysis of recent Russian and foreign literature on formulation of hydrophobic emulsions for well stimulation and improved oil recovery applications suggests the current importance of intended studies and highlights the current trend towards enhanced use of chemicals for stimulation of oil production wells and complex, heterogeneous carbonate reservoirs. Furthermore, absence of crude oil in the hydrophobic emulsion composition is very beneficial in that it provides reduction of labor, economic and material costs due to optimization of repeated treatments of near wellbore zones in carbonate reservoirs and killing of difficult wells.

Key words:

carbonate reservoir, hydrophobic emulsion, diverter, emulsifier, oil-free base, basic formulation, dynamic viscosity, shear rate, structural and mechanical properties
