A Weighted Fracturing Fluid System for Deep Well Stimulation Treatment

Abstract:

Petroleum industry is focusing on high-pressure and high-temperature (HPHT) reservoir. The major problem facing to HPHT reservoir is to generate enough bottomhole pressure without exceeding the limitations of equipment on the ground. In order to overcome these problems, weighted fracturing fluid system has been developed whose density can reach up to 1.50 g/cm3. This paper summarizes a study on formulating sodium bromide and sodium chloride as a combined weighted agent and a delayed crosslinked fracturing fluid system which is to cater the fluid and treatment guidelines for the fracturing application. Extensive studies were also conducted to determine temperature stability and anti-shear properties and gel broken.
