CADANGAN

• Perhitungan In Place pada struktur MV mengunakan persamaan 90%P1 + 50% P2

• Dalam perhitungan cadangannya, struktur MV menerapkan radius pengurasan sebesar 250 m (untuk oil) dan 750 m (untuk gas)

• Dengan jumlah In Place tersebut struktur MV dikategorikan sebagai lapangan yang tidak/belum komersil untuk dikembangkan.
