Abstract

Mumbai High field located in the western offshore of India, is a giant structure, established hydrocarbon in Miocene carbonates of L-III, L-II & L-I and Basal Clastics as a secondary reservoir. Commercial quantities of hydrocarbon were discovered from Basal Clastics first in 1976, subsequently 97 wells have penetrated into the Basal Clastics, out of which 59 wells proved to be hydrocarbon bearing. Presently 15 wells are producing from Basal Clastics with cumulative production of 8000 BOPD.
