Abstract
Embodiments disclose methods of estimating porosity from a pore volume and bulk density. The porosity is obtained by multiplying the pore volume and bulk density. Methods disclosed in the subject disclosure are minimally affected by errors in the bulk density measurement.
Claims17
A method of calculating porosity of a rock sample from an unconventional hydrocarbon reservoir comprising:
- measuring a pore volume of the rock sample from the unconventional hydrocarbon reservoir using a device selected from the group consisting of gas sorption, pycnometry or mercury intrusion porosimetry, or combinations thereof;
- measuring a bulk density of the rock sample from the unconventional hydrocarbon reservoir using a density measuring device;
- and
- using a processor to compute a porosity of the rock sample wherein the porosity is obtained by multiplying the measured bulk density by the measured pore volume.
A computer program comprising non-transitory machine readable instructions stored on machine readable media, the instructions for calculating porosity of a rock sample from an unconventional hydrocarbon reservoir comprising:
- receiving input data comprising a pore volume and a bulk density;
- and
- computing a porosity of the rock sample by multiplying the bulk density by the measured pore volume.
