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.
