QUATERNARY AMMONIUM SURFACTANT BASED FRACTURING FLUIDS FOR IMPROVING OIL WELL FRACTURE EFFICIENCY

摘要

The present invention relates to formulating the Viscoelastic surfactant base fracture fluid (VES) and identifying suitable chemicals. The rheological behavior of the fracture fluid (VES) is studied in varied temperature (up to 80d deg C) range with graded amounts of surfactants and counter ion. This innovation formulates a low temperature fracture fluid (up to 80 deg C) that does not require any breaker and break on contact with hydrocarbon.
