ABSTRACT:
Hydrocarbon stimulation fluids are often used to increase the permeability and productivity of oil and gas reservoirs. The fluid itself is made up of a mixture of hydrocarbons and various chemicals designed to induce gel formation and gel breaking. The successful removal of these chemicals from the fluid has been achieved, through a process of acid-washing, mixing with a settling agent, centrifugation and filtration. This will allow the fluid to be re-used many times for further fracturing processes.
