Abstract
In situ (subsurface) methods and devices are described for releasing gaseous hydrocarbons and steam from solution in water or brine, from captured bubbles in formation pores, and from hydrate deposits. With geopressured brines the volume of the brine is reduced so that its volume is less than the sandstone pore volume which holds the brine; at this point the reservoir creates a gas cap of methane and steam which can be produced. Gas caps are formed in natural domes, artificial domes are developed, down-hole engines and pumps are powered both by in situ forces and by surface-generated forces; all are described.
