Field tests of electromagnetic heating of oil - PetroWiki

Below are the field cases in which applied power was reported together with the oil production increase, so that we can evaluate and compare the energy gains of the different processes tested. Comments The EG calculation assumes that the power reported is the 60 Hz power of the HF power supply. Data reported by Pizarro and Trevisan[3] Comments Test stopped after 70 days of heating because of voltage control system problems. Comments Both wells were badly sanded, and operations were suspended. There was a history of short circuits and power supply problems (casing isolation failure suspected).
