National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Field Study of Viscous Oil Production by Solvent Stimulation, Wilmington, California.

PB214034

Publication Date	1972
Personal Author	Lechtenberg, H. J.; Gates, G. L.; Caraway, W. H.; Baptist, O. C.
Page Count	20
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)
