Granted: 2002-03-12
Abstract: Apparatus and method are provided for producing fluid from a wellbore extending into a hot subterranean hydrocarbon-bearing formation containing water at greater than 100 °C. The wellbore is divided into three co-extensive passageways; an annulus, and first and second conduits. The annulus is formed within the wellbore between a block at its bottom above the completion intervals and an outlet at the wellhead. The first conduit extends from the formation, through the bottom of the annulus and to an outlet at an elevation intermediate up the annulus. The first conduit is insulated between the bottom of the annulus and its outlet. A second conduit extends between the bottom of the annulus and an outlet at the wellhead. In operation, by producing fluid from the annulus and the second conduit outlets at the wellhead, formation fluid is induced to rise up the first conduit.  While the fluid rises, contained water flashes providing steam-enhanced lift. The now-cooled fluid flows out of the first conduit's outlet and into the annulus, separating into substantially gas-phase and liquid phase fluids which flow up and down the annulus respectively.  The gas phase fluid is produced from the top of the annulus.  Liquid-phase fluid pools in the bottom of the annulus may be artificially lifted through the second conduit using gas-lift or pumps for production at the wellhead outlet.

Title: Nuclear quadrupole resonance testing
Inventor: PEIRSON NEIL FRANCIS
IPC: G01R33/46
Filed: 1997-08-28
Granted: 2007-01-16
Abstract: Methods of testing a sample in which long composite pulses comprising a sequence of short closely spaced pulse elements are disclosed. The pulses generate a qualitatively different response characteristic, which can be tailored as desired by suitable adjustment of the pulses. Near sinusoidal dependence on pulse length can be attained, and effective, efficient, inversion pulses can be produced. Typically each pulse element generates a small flip angle of a few degrees, and the sequence contains tens or even hundreds of elements. Similar excitation and effects may be produced by amplitude modulating a carrier, rather than switching pulses on and off; there is little discernible difference in the excitation seen by the sample.

Abstract: An apparatus for controlling the speed of an induction motor includes a first winding and a second winding. The first winding and second winding are adapted to be coupled to an AC source for supplying an AC input signal. A first switching device is coupled to the first winding and a second switching device is coupled to the second winding. Each of the switching devices is operative in a low impedance state enabling current to flow through the associated winding of each switching device and a high impedance state preventing significant current flow through the associated winding of each switching device. A controller switches each of the switching devices from the high impedance state to the low impedance state in a sequence for controlling the current in the windings, which induces a phase shift between the AC voltages across the windings.
