Recovery of Heavy Oil From the Monterey Formation in Offshore California By Cyclic Injection of Light-Oil Diluent

摘要

This paper describes a single-well pilot in which light-oil diluent was injected through tubing to lower in-situ oil viscosity and increase production form a low-gravity oil well. The pilot well is located on the Heritage platform in the Santa Ynez Unit and pro- duces form the Monterey formation. The pilot validated laboratory data suggesting that large production-rate increases could result from high-rate diluent injection.
