RAMIA, M.E; MARTIN, C.A  and  JEANDREVIN, S. Determination of liquid water content in rocks by measurements of dielectric capacity. An. AFA [online]. 2017, vol.28, n.2, pp.61-65. ISSN 0327-358X.

This work describes a non-destructive procedure for the determination of liquid water content in pores of sedimentary and shale rocks by means of measurements of the dielelectric capacity (CD). These studies concentrates on determining the water content in rocks, mainly from oil shale reservoirs, whose principal characteristic are its very low permeability, low porosity and small pore sizes. The samples provided were preserved rotated plugs from the Vaca Muerta basin (Neuquén, Argentina). The results show that this method allows precise determination of the water content which turns out relevant in order to evaluate the amount of oil from Nuclear Magnetic Resonance (NMR) measurements of the total proton content (assuming the oil hydrogen index equals to one).
