Abstract
Clathrate reservoirs of Class II are modified in order to improve the ability to produce hydrocarbons from them. Specifically a method for improving producibility of subsurface clathrate formation underlain by a mobile aquifer includes drilling a borehole to a depth providing access to the mobile aquifer and injecting a material into the mobile aquifer such that the material passes through pore spaces and forms a barrier underlying the clathrate formation and substantially impeding fluid flow from the mobile aquifer into contact with the clathrate formation.
Claims11
A method of improving producibility of a subsurface clathrate formation underlain by a mobile aquifer, comprising:
- identifying a subsurface clathrate formation underlain by a mobile aquifer;
- drilling a borehole to a depth providing access to the mobile aquifer;
- and
- injecting a material into the mobile aquifer, wherein the material is selected and an amount injected is selected such that the material passes through pore spaces and forms a barrier underlying the clathrate formation and substantially impeding fluid flow from the mobile aquifer into contact with the clathrate formation.
