Title: Methods for restoring productivity to gas wells in the Clinton sand of Ohio: a laboratory and field experiment

Abstract

A series of laboratory experiments were conducted to determine the most efficient method to remove paraffin deposits in the well bore and fracture system of gas wells in the Clinton Sand of Ohio. After experimenting with ultrasonic energy, solvent stimulation, and thermal stimulation, it was concluded that the thermal stimulation method was the most attractive for field trials. After designing a pilot project consisting of 3 wells, 2 of these wells where the paraffin problem was evident were thermally stimulated using a down-hole gas burner to create a high temperature gradient from the well to the fracture system and formation. After several days of stimulation, it was observed that the wells were indeed stimulated but not to the magnitude originally expected, mainly because of the extremely low permeability of the formation involved and because of the low pressure gradient existing in the stimulated wells.
