Classification: CPC G | IPC G

Claim 5:
6. A method according to claim 4, wherein:
the parameter indicative of bound fluid volume in the porous rock sample is given as BFV and is calculated as

BFV=1/A∫T2minT2maxdT2∫Pc=Pc-cutPc=Pc-maxƒ(Pc,T2)dPc,

where A is the normalization parameter defined as

A=∫T2minT2maxdT2∫Pc-minPc-maxƒ(Pc,T2)dPc,

where ƒ(Pc,T2) is the probability distribution function of capillary pressure values as a function of transverse relaxation values,
Pc represents a dimension of the capillary pressure values,
Pc-max represents a maximum capillary pressure value,
Pc-min represents a minimum capillary pressure value,
Pc-cut represents a capillary pressure value at which fluid is considered bound,
T2 represents a dimension of the transverse relaxation values,
T2max represents a maximum T2 value, and
T2 min represents a minimum T2 value.
