FORAMINIFERAL ZONATION OF SVOC FAIRE
NO. 1 WELL, CAGAYAN, LUZON

ABSTRACT



Studies made on ditch samples from Faire #1 well drilled by Standard Vacuum Oil Co. in the Cagayan Valley revealed seven (7) foraminiferal zones established on the basis of limited age ranges of small Foraminifera association and (or) marker species. Three sedimentary rock units ranging in age from middle Miocene to Pleistocene were penetrated by the drill hole. Formational contacts based on paleontological evidences were delimited and found to roughly coincide with the same contacts established by electric logs, micrologs, and estimated thicknesses of the three formations. Repetition of beds occurs at 8,530 feet as indicated by the recurrence of late Miocene (Tert. f3) species below that depth.
