Dynamic analysis as a method of wells interaction evaluation in making technological decisions

Abstract

The complexity of developing oil fields determines the creation and improvement of fundamentally new approaches to the analysis and management of various technological processes of oil production based on indirect methods of interpreting current geological and field information for making strategic and tactical decisions to rationalize it.This article discusses the formation of stagnant and poorly drained zones of oil deposits due to the redistribution of hydrodynamic flows of reservoir fluids.
 In order to analyze and evaluate the effectiveness of applying the technology to change the direction of filtration flows in the reservoir under consideration, it is necessary to study the influence of non-stationary processes on oil production.
 Based on the construction of operational maps of total oil and water production, water cut and the degree of interaction by periods of development, the state of the reservoir system is analyzed and conclusions are made about the characteristic features of the direction of water-oil flows with the subsequent formation of stagnant zones.
 The proposed approach to decision-making allows to carry out the dynamic regulation of hydrodynamic flows in order to stabilize and reduce oil production losses for the period under consideration and make the necessary decision on the issuance of technological recommendations for the impact on the operation of the exploitation object, taking into account the minimization of energy and resource costs.
 The proposed method was tested on the example of the analysis of the state of development of one of the fields in Azerbaijan, which is in the final stage of development. As an information array, the dynamics of changes in oil and water flow rates by wells in various periods of development was chosen.

Development of a calculation scheme for selecting the optimal mode of operation of a gas condensate well taking into account the deformation conditions of the formation

“…These factors, by their nature, begin to occur themselves with the time of field development, and, as a rule, are not taken into account in the initial development project due to the incomplete validity of information about the time and degree of occurrence of these factors. To avoid the negative after-effects of the influence of these factors, it is required to constantly monitor the process of field development in order to timely establish the discrepancy between the actual and design values of development indicators [1][2][3][4].…”
