I have been searching without much success on the current status of the:

Mallik Gas Hydrate Production Research Program (Placemark Pt.)

Please post "more specific text" relative to the production aspect of this project
or any other Methane Hydrate site in a "production" test mode


I located the abstract below:

Japan Oil, Gas and Metals National Corporation (JOGMEC) and Natural Resource Canada (NRCan) have embarked on a new research program to study the production potential of gas hydrates. The program is being carried out at the Mallik gas hydrate field in the Mackenzie Delta, a location where two previous scientific investigations have been carried in 1998 and 2002. In the 2002 program that was undertaken by seven partners from five countries, 468m3 of gas flow was measured during 124 hours of thermal stimulation using hot warm fluid.

The primary production test well was established during the 2007 field season with the re-entry and deepening of JAPEX/JNOC/GSC Mallik 2L-38 well, originally drilled in 1998.

Production testing was carried out in April of 2007 under a relatively low drawdown pressure condition. Flow of methane gas was measured from a 12m perforated interval of gas-hydrate-saturated sands from 1093 to 1105m.

The results establish the potential of the depressurization method and provide a basis for future prolonged testing planned in the near future

The Abstract says nothing about thermal stimulation during 2007.
i have noted brief comments in small write ups that
a combination of depressurization and thermal stimulation was used.

I am curious what form of t_stimulation was utilized,
such as soluble reagents with SO3 & HCL?

Future Trends: - Catalyst allowing conversion of natural gas hydrate and liquid CO2 to CO2 hydrate and natural gas


******
hot warm fluid noted in the abstract applies here:

Spatial and temporal variation of temperature during a gas hydrate production test (Mallik 2002)

The thermal stimulation test was successful in that the bottomhole temperature was increased and held constant in excess of 50 �C; gas from dissociated gas hydrate was produced, sampled, and flared at surface;

Note: The Thermal Recovery Method at this site does not state anything about "ACIDS" for inducing heat.

depressurization method:

Methane gas is extracted by reducing the pressure inside the well by reducing the specific gravity or amount of the drilling mud, causing the methane hydrate to decompose.



As with geological formation, methane hydrate bearing layers are subject to be pressurized by the combined overburden weight of seawater and the formation pressure. In drilling for formations subjected to such pressures, it is customary to use a drilling mud with a specific gravity higher than this pressure.

**** Note by joe: drilling mud = Chemicals ****

Conversely, the depressurization method lowering the pressure inside the well and encouraging the methane hydrate to dissociate. (Methane hydrate dissociates into methane gas and water when depressurized.)

However, depressurizing inside the well will not necessarily lead to depressurization of the entire methane hydrate-bearing layer. Research continues in an effort to find an efficient method of evenly reducing the pressure of methane hydrate-bearing layers.
