New Fluid Technology Improves Well Productivity in the Western 31S Stevens Oil Zone in the Elk Hills Field

摘要

This paper presents a comparative well study performed in the central California Elk Hills field,Western 31S(W31S) Stevens Oil Zone.Stimulation of the W31S Stevens Oil Zone using hydraulic fracturing with conventional polymer fluids is compared with the use of a new viscoelastic high performance fracturing fluid(HPF).
