Abstract
Experience in development of oil deposits testifies that filtration parameters of bottom-hole formation zone are gradually declining due to killing and exploitation of wells. The main cause of this is utilization of water-based technological fluids which are currently widely used in the oil industry. A significant attention is paid nowadays to increasing the reservoir penetration area by use of active acids to stimulate oil and gas wells. Hydrocarbon-based compositions, particularly invert emulsions, are alternative systems to solve these problems.
