Title: San Ardo, A Stratigraphic Analysis: ABSTRACT

Author(s): Thomas A. Baldwin

Article Type: Meeting abstract

Abstract:

The San Ardo oil field occurs in a stratigraphic trap at the updip shale edge of the Lombardi sand (upper Miocene). The water table of the field was warped synclinally during early Pleistocene time. The San Ardo field accumulated therefore during the Pliocene. Pliocene sediments of the area are described and termed the "San Ardo group," including three partly interbedded and time equivalent facies, Pancho Rico, Etchegoin, and Paso Robles.

It is shown that the shorelines or buttressed edges of sands occurring in the Salinas area have not been favorable for accumulation. It is suggested that Pleistocene structures should be discounted during future exploration in the Paso Robles-Salinas area.
