| Abstract | In order to evaluate the productivity of gas hydrate by the depressurization method, Japan Oil, Gas and Metals National Corporation and Natural Resources Canada carried out a full-scale production test
in the Mallik field, Mackenzie Delta in April 2007 and March 2008. An extensive wireline-logging program was conducted in 2007 to evaluate physical reservoir properties of gas-hydrate-bearing sediments, to determine production-test and
water-injection intervals, to evaluate cement bonding, and to interpret gas hydrate-dissociation behaviour throughout the production test.
New open-hole wireline-logging tools, such as the Magnetic Resonance ScannerTM, True Resistivity ScannerTM,
Sonic ScannerTM, and other advanced logging tools, such as Elemental Capture SpectroscopyTM, were deployed to obtain precise data on the occurrence of gas hydrate, lithology, gas hydrate pore saturation, porosity, and permeability. Perforation
interval of the production-test and water-injection zones was determined through a multidisciplinary approach, using geological-petrophysical analysis and interpretation of open-hole logging data, construction of layered reservoir models, quick
reservoir numerical simulations for several perforation scenarios, and operational constraints. A gas-hydrate-bearing formation from 1093 to 1105 m KB was selected for the 2007-2008 production test, and three zones (1224-1230, 1238-1256, and
1270-1274 m KB) were selected for the injection of produced water.
Cased-hole logging measurements with the Reservoir Saturation ToolTM, Accelerator Porosity SondeTM, and Sonic ScannerTM were also conducted to evaluate physical-property changes of
the gas-hydrate-bearing intervals before and after the production test (time-lapse analysis). Analysis of these cased-hole logging data provided important knowledge about gas hydrate-dissociation behaviour. |
