The Franklin heavy oil field, Venango county, Pennsylvania was discovered inlate 1859 but is, today, virtually abandoned. Geologic data reveal that theshallow producing formation, Devonian in age, has been productive over onlyhalf of the field area but that in excess of 60 million barrels of crude oilremain in place. The gravity of this "heavy oil" (a misnomer in light of ourpresent definition) is about 31°API, and the crude is distinguished by itsparaffinic base, naphthenic light ends and good market value. Recently it wasannounced that a steam injection pilot test was to be initiated in this field.In view of this development, a simulation of the steam injection process for anindividual pattern within this field has been made using available physicaldata and published mathematical models. A description of the field and detailsof the simulation are presented in the paper.
The Franklin heavy oil field, located in Venango County, Pennsylvania, wasdiscovered soon after the completion of the Drake well in 1859. The field wasdeveloped over a period of years, but for all practical purposes it is nowabandoned. Recently, however, it was announced that a steam injection pilotproject was to be initiated in a segment of this field. This study, performedindependently of any request or commission, was made to characterize, in anapproximate manner, the engineering parameters of this particularinjection-production system.
This field received its name soon after its discovery. In light of ourpresent concepts, however, the term "heavy oil" is a misnomer because crude oilfrom the Franklin heavy oil field has a gravity in the range of 31-32°API,anomalously low for Pennsylvania crudes. Because of the large percentageof high-grade lubricating oils contained in the crude, it commands a highmarket value. It is estimated that this field has an in-place crude oil volumein excess of 60 million barrels.
