ABSTRACT:
Method and apparatus are disclosed for recovering geopressured methane gas dissolved in ocean depths including at least a pair of spaced-apart electrodes lowered into electrical contact with the geopressured methane dissolved in the ocean salt water at a selected depth. The salt water carrying the dissolved methane gas acts as an electrolyte. The electrodes are insulated from substantially all overlying ocean above the selected depth to establish an electrical circuit composed of the spaced-apart electrodes and the salt water electrolyte at the selected depth containing the methane gas. An AC electrical current flow is then established through the electrodes and the salt water electrolyte for establishing an AC electrical field surrounding the electrodes and releasing molecules of free methane gas which rises vertically to the ocean surface. Means are provided at the ocean surface for trapping and recovering the free methane gas.
