Prolific amounts of oil and gas have been produced from the San Joaquin Basin in many different oil and gas fields. In many cases, the petroleum system is easily identifiable, and the path hydrocarbons take from source area to trap are known. This study aims to identify secondary migration pathways of hydrocarbons from the source to the trap in an oil field near Fresno, California, where the source is about 35 miles from the trap. To create an accurate subsurface interpretation of the study area, 3D seismic data and more than 300 well logs were used. From subsurface structure maps, net sand maps, an Allan profile, and regional research, it was found that there are two possible migration scenarios that reasonably describe the secondary migration of hydrocarbons into the study area. Six normal faults within the field play large roles as seals and/or migration pathways, and to better understand hydrocarbon migration in the study area, further work must be done on the sealing/leaking behavior of the faults within the field.
