Abstract
An apparatus and method for enhancing the extraction of hydrocarbons from an underground reservoir using a well is disclosed. The apparatus comprises a power source operable to supply periodic electrical power at a first frequency; at least one impulse generator unit operable to convert the periodic electrical power at the first frequency into periodic electrical power at a second frequency and to couple electromagnetic energy generated by the periodic electrical power at the second frequency into the reservoir, the second frequency being at least ten times higher than that of the first frequency; and a conducting cable being operatively coupled between the power source and the at least one impulse generator unit.
