Linear olefin monomers, and particularly alpha-olefins, having a pour point greater than -102°, a flash point greater than 10° and a boiling point greater than 121° are proposed as frac fluids in treatment of oil and gas wells by fracturing. Linear olefin monomers are injected into the well, and fracturing pressures applied to the well to fracture the well. Linear olefin monomers may be mixed with a liquified drive fluid such as CO2, preferably with the CO2 forming a miscible bank ahead of the linear olefin monomers for use in driving the load fluid from the well.
