Field Geophysical Researches (Inflow Profile and Acceleration Performance Recording, Column Leakage Identification)


These researches are based on registration of physical fields determined by existance and structure of fluid streams in a well borehole and in a space around it. Measurements are done at stable (exploited for a long period of time wells), unstable (wells with changing mode of production) and transitional thermohydrodynamic fields. Unstable modes appear after putting a well into operation or its shutting off ...

System of Geophysical Methods:


  • gamma-logging;
  • magnetic collar locator;
  • barometry;
  • high sensitivity thermometry;
  • dielmetric hydrometry;
  • induction resistometry;
  • inflow thermoconduction indicator;
  • mechanical flowmeter logging.

Typical Conditions of System Application:


  • in cased wells filled with any circulating fluid or gas;
  • in any method of formation exposure (perforation, filter on a tail, etc.);
  • at any types of inflow inducing (in gushing wells, at compression, swabbing or at jet pump operation.)
