Summary
In this paper, we present a novel method for in situ estimation of two-phase
transport properties of porous media using time-lapse resistivity, pressure,
and flow rate data from permanent downhole pressure, electrode resistivity
array (ERA), and production logging tools. The objective of this fluid movement
monitoring (FMM) experiment is to develop a new downhole hardware assembly, new
measurement procedures, and associated interpretation techniques for inferring
oil recovery factor, relative permeabilities to oil and water, and other
two-phase flow properties.
An oil well in a carbonate reservoir in Saudi Arabia was dedicated to
conduct a week long extensive openhole monitoring data acquisition, enabling us
to carry out suitable a priori characterization. This approach is new to
the oil industry and is the first field experiment for direct determination of
two-phase flow properties through successful integration of the downhole
resistivity array and pressure data. Together with pressure transient
responses, the ERA measurements allowed characterization to a radial distance
of tens of meters from the wellbore.
