Abstract
This paper describes a single-well pilot in which light-oil diluent was inj ected through tubing to lower in-situ oil viscosity and increase production from a low-gravity oil well. The pilot well is located on the Heritage pla tform in the Santa Ynez Unit and produces from the Monterey formation. The pilot validated laboratory data suggesting that large production-rate incre ases could result from high-rate diluent injection.
