Abstract Preliminary results are given of solvent stimulation of two wells producing viscous oil (14-17 degrees API) in the Wilmington field, California. The solvent (coker oil) was injected into the formation, and, after a soak period, the well was returned to production. Data are given on crude oil properties, solvent properties, determination of volume of solvent in the produced oil, rate of oil production before and after stimulation, volume of additional oil produced, and volume of solvent recovered. Cyclic solvent stimulation appears to be a success. (Author)
