Annotation:

The effective planning of fields’ development when placing wells requires taking into account the variability of reservoirs characteristics properties of the reservoirs of the target formation. As a geological hypothesis, there is a relationship between the energy feature of the near-well zone of a horizontal wellbore and its location on a paleostructural basis. To test the proposed hypothesis, the rate of the change of the wells energy state and their position on the structural plan along the top of the Upper Jurassic deposits was compared. For getting the possibility of digitizing the desired dependencies, the "structural factor" parameter is introduced. The use of field pressure data from reference wells allowed obtaining a three-dimensional graph of the dependence of the rate of tubing pressure change on the structural factor and time.
