| Abstract | In the winter of 2007, Japan Oil, Gas and Metals National Corporation, Natural Resources Canada, and Aurora College/Aurora Research Institute acquired induction, laterolog, and triaxial
induction-resistivity measurements over the gas-hydrate-bearing formations in the Aurora/JOGMEC/NRCan Mallik 2L-38 gas hydrate production research well.
The most common well-log analysis techniques for computing saturation in gas-hydrate-saturated
intervals are the Archie-based resistivity approach and the porosity deficit between the formation density and magnetic resonance. The two approaches have been considered to give similar results in gas-hydrate-saturated reservoirs when the input
Archie parameters, such as Rw, m, and n, are well known. However, conductive shale layers associated with the presence of thin sand-shale laminations have a profound effect on resistivity logs and can cause significantly lower readings than those of
the high-resistivity sand layers. This is known as resistivity anisotropy. If resistivity anisotropy is not considered, the Archie-based resistivity approach can lead to pessimistic water-saturation computations. |
