Nuclear Magnetic Resonance

Nuclear Magnetic Resonance (NMR) is a non-invasive and non-destructive measurement for pore fluid characterization used in lab settings to evaluate total fluid porosity, fluid typing and rock texture.

Imbibition Testing

Samples are introduced to water through humidification and hydrocarbons through immersion in the produced fluid to allow the samples to return to its native saturation through spontaneou imbition. Plugs are run through alternating cycles of exposure to different fluids with different initial fluids to minimize preferential imbibition.

Wettability Partitioning

NMR scans at 12 MHz frequency are performed as samples are exposed to alternating water-hydrocarbon cycles. The changes observed in the T1-T2 maps indicates pore spaces of varying wettabilities.

Relative Permeability

Spatial T2 scans on plugs during injection of fluids allows for more accurate saturation monitoring compared to traditional relative permeability testing and can be performed on low permeabilty samples using our high resolution flow meters and pumps.
