Paper Number: SPE-192904-MS
..., such as permeability, fluid typing, capillary pressure, and the estimation of movable fluid volume, etc. One of the most important Petrophysical property NMR data can provide is the determination of potentially producible porosity which is called bulk volume of movable fluids (BVM) or free fluid index (FFI...

Figure 26 The BVI-FFI cut-off for the MRIL log is at the minimum of the sum of the differences squared between the amount of bound fluid (BVI) in the core plugs and the MRIL T 1 / T 2 spectra at the depth of the plugs, integrated up to relaxation time T(i). More

.... Then, the NMR log data were used to calculate the ratio of free fluid index (FFI) to bulk volume irreducible (BVI). A large FFI-to-BVI ratio indicates better rock quality. Combining rock quality from the Bouma sequence and FFI-to-BVI ratio eliminates the poor-quality rocks in pressure-testing point selection...

... permeability equation an equivalent classification of water saturated core plug samples can be obtained. This means that port size, and the ratio of free fluid index over bound fluid index, FFI/BFI, are equivalent. The described NMR method has been applied to 60 core plugs samples of a clastic sedimentary...

... Determining reliable core T2 cut-off using desaturated oil over conventional gas is an important step while applying in NMR T2 distribution in the wireline log domain, in order to reduce an uncertainty related to BVI, FFI and irreducible water saturation (Swirr) across the field. Although a T2...

... moments, the precession generates an alternating voltage in the coil of the logging sonde. The amplitude of this voltage, at the instant precession starts, is proportional to the hydrogen nuclei concentration in the formation and is translated to free fluid index (FFI). Normally, the FFI is a measure...
