Subsurface connection methods for subsurface heaters

Patent Vinegar, Harold J [Bellaire, TX]; Bass, Ronald Marshall [Houston, TX]; Kim, Dong Sub [Sugar Land, TX]; ...

A system for heating a subsurface formation is described. The system includes a first elongated heater in a first opening in the formation. The first elongated heater includes an exposed metal section in a portion of the first opening. The portion is below a layer of the formation to be heated. The exposed metal section is exposed to the formation. A second elongated heater is in a second opening in the formation. The second opening connects to the first opening at or near the portion of the first opening below the layer to be heated. At least a portion ofmore »« less

Method and an apparatus to control the lateral motion of a long metal bar being formed by a mechanical process such as rolling or drawing

Patent Chang, Tzyy-Shuh [Ann Arbor, MI]; Huang, Hsun-Hau [Ann Arbor, MI]; Lin, Chang-Hung [Ann Arbor, MI]

An adjustable guide, includes two or more mechanisms each having a rotatable retaining element containing a retaining groove with a variable radius in its perimeter surface. The grooves form a guidance path to control the lateral, i.e. non-axial, motion of a long bar moving along a longitudinal axis during a production process.The diameter of the guidance path varies according to the variable radii of the grooves. The guidance path increases in size at a predetermined rate, from a point of origin to an end point on the retaining groove. Rotating the retaining elements causes the diameter of the retaining groovesmore »« less

Patent Chang, Tzyy-Shuh [Ann Arbor, MI]; Huang, Hsun-Hau [Ann Arbor, MI]; Lin, Chang-Hung [Ypsilanti, MI]

An apparatus to control lateral motion of a bar moving along a guidance path includes a pair of rotatable hubs each having at least first and second rollers at locations around the perimeter of the hub. The first roller has a first retaining groove of a first radius and the second roller has a second groove of a second radius smaller than the first radius. Each hub further includes at least one guiding element located between the rollers with a guide channel extending in the outer surface. A mounting system allows the hubs to be rotated between first and secondmore »« less

Subsurface heaters with low sulfidation rates

Patent John, Randy Carl; Vinegar, Harold J

A system for heating a hydrocarbon containing formation includes a heater having an elongated ferromagnetic metal heater section. The heater is located in an opening in a formation. The heater section is configured to heat the hydrocarbon containing formation. The exposed ferromagnetic metal has a sulfidation rate that goes down with increasing temperature of the heater, when the heater is in a selected temperature range.

Three-phase heaters with common overburden sections for heating subsurface formations

Patent Vinegar, Harold J [Bellaire, TX]

A heating system for a subsurface formation is described. The heating system includes three substantially u-shaped heaters with first end portions of the heaters being electrically coupled to a single, three-phase wye transformer and second end portions of the heaters being electrically coupled to each other and/or to ground. The three heaters may enter the formation through a first common wellbore and exit the formation through a second common wellbore so that the magnetic fields of the three heaters at least partially cancel out in the common wellbores.
