Paper presented at the SPE Enhanced Oil Recovery Conference, July 19–20, 2011
Paper Number: SPE-144016-MS
... under reservoir conditions, a single-well, multi-zone injection test using Log-Inject-Log (LIL) techniques was executed. The objectives of this test were to determine injectivity of ASP fluids and to estimate changes in residual oil saturation (S or ) in the near-wellbore region. This paper discusses...

.... This paper proposes a new application of the NMR log-inject-log method to improve assessment of permeability and to distinguish isolated pores from connected pores. We propose injecting manganese-bearing solution in the rock samples and simultaneously analyze NMR measurements before and after injection...
