Abstract
An apparatus and method for wellbore and formation heating. In the method, after perforation of the well, fracturing material is pumped into the perforations to fracture the formation. This fracturing material comprises a mixture of sand and thermosetting plastic. Heat is subsequently applied to the formation and thereby to the plastic to cause the plastic to set so that flow-back of the plastic and sand is prevented while still allowing fluid flow from the formation through the sand into the well casing. The heating apparatus comprises a dual tubing string with a burner chamber attached to the lower end thereof The outer tubing of the dual tubing string is adapted for connection to an oxygen source, and the inner tubing string is adapted for connection to a fuel source. The apparatus also comprises an ignition source for providing a spark to ignite the fuel and oxygen mixture. The ignition source may be a mechanical device such as a grinding wheel rotating against a ferrous element, or an electrical device, such as a spark plug.
