Abstract

Recent successful testing in some deeper Raageshwari wells from deep Volcanic reservoirs (shallow Basalt and deep Felsic zones) below the established Gas-Down-To (GDT, 3393m) have flowed light oil (API 48-50 deg) down to a depth of 3474mSS (Oil-Down-To or ODT). After the detailed study on testing data and subsurface understanding in terms of net reservoir distribution, both the technical and commercial merits were established to produce the oil rim along with existing shallow Gas leveraging the ongoing in-fill drilling campaign in the RDG field. This technical paper highlights the potential and the opportunities to produce the oil as commingle flow along with the Gas in the most costeffective way. Also, it was envisaged that future production of oil would not be possible from these wells accessing the deeper zones due to subsurface complexities and cost implication. The monetization plan increased the reserve by ~1.3mmboe with an additional average production of ~350boepd Oil.
