* Measure R<sub>bt</sub> directly on core samples, then correct it to reservoir conditions using methods of the preceding section (e.g., <ref name=ch09r62>Thomas, L., K., Katz, P., L., Tek, M., R., 1968, Threshold pressure phenomena in porous media: SPE Journal, June, p. 174–184.</ref><ref name=ch09r54 />).
