Time-average relation in compacted formations (porosity/transit time relationships)

Input(s)

δ\delta t: Total Travel Time (μs/ft)(\mu \mathrm{s} / \mathrm{ft})

δtf\delta \mathrm{t}_{\mathrm{f}}: Travel Time in Liquid/Fluid (μs/ft)(\mu \mathrm{s} / \mathrm{ft})

δtma\delta \mathrm{t}_{\mathrm{ma}}: Travel Time in Matrix (μs/ft)(\mu \mathrm{s} / \mathrm{ft})

Output(s)

Ø: Porosity (fraction)

Formula(s)

=δtδtmaδtfδtma\varnothing=\frac{\delta t-\delta t_{m a}}{\delta t_{f}-\delta t_{m a}}
