Researchers discover new fundamental property of rocks

National Oceanography Centre

The pore network The discovery of a new fundamental rock property will improve estimates of underground resources, such as hydrocarbons and drinking water, as well as CO₂ storage reservoir capacity. This finding will improve the interpretation of geological fluid flow from geophysical surveys. Fluids and electrical currents can flow through sedimentary rock via a network of gaps in between the sediment grains, called pores. However, because the unique electrical resistivity measurement system and processing software that I developed at the NOC is so accurate, I knew that the data must be the result of a ‘real’ rock property. Anomalous electrical resistivity anisotropy in clean reservoir sandstones., 62: 1315–1326.
