Abstract: For production of hydrocarbons from a hydrocarbon formation through a well in a condition of fluctuations in the formation pressure, in addition to transformation of a formation fluid into a gas-liquid flow, the bottomhole pressure is automatically regulated at a level higher than saturation pressure of the formation fluid, regardless of any changes in properties of the formation and the formation fluid. At the same time, the speed of the flow of the formation fluid from the bottomhole to a location of transformation is maintained automatically at a level to be sufficient for the transformation of the formation fluid into the gas-liquid flow.

Abstract: The invention constitutes a dilating catheter for blood vessels in which the catheter is constituted of a hollow radiopaque tube designed to be snaked into the blood vessel and includes a working guide inside the tube which is both longitudinally movable and rotatable. The working guide is in the form of a flexible guide which arcs out from the longitudinal axis at the distal end and rotate in three dimensions. The arc portion is designed to be located at a single point or at several points along the flexible guide, where a stenosis, i.e. vessel constriction, is located. The guide rotates to distend the tube and thereby the blood vessel at the stenosis location. The guide is connected to a rotational drive, through a speed reducer. It is also connected to a gauge which measures the mechanical resistance of the guide to rotation and to an integrating meter which integrates the mechanical resistance to rotation, to provide the physician with interactive control over the dilation process.
