Adjusting experimental set-up improves relative permeability reliability
Abstract
An improved experimental set-up for relative permeability measurement and interpretation methodology has been developed. The improvement was aimed at two objectives: to modify the equipment in order to obtain more reliable experimental data and to interpret them appropriately. Special emphasis was laid upon pressure drop oscillations and uncertainties in water saturation measurements. Relative permeabilities are inferred by interpreting production data using the JBN method and verifying them by simulation.
