Analysis of the Results of Deformation Monitoring by the Inclinometer System at the Vladimir Filanovsky Field

Abstract

The system of geodynamic monitoring at the Vladimir Filanovsky oil and gas condensate field is presented. The technologies for data transfer to the processing center, their decoding from the internal format of the recorders and loading into the processing system, and database organization are described. The algorithm for identifying and eliminating defects of various kinds that inevitably occur in the data during geodynamic monitoring at an operating industrial facility is described in detail. The maximum recorded variations of platform slopes are shown for a period of 1.5 years. The measured trend speed is compared with the maximum permissible one. Mathematical modeling of the stress-strain state due to the development of an oil-saturated formation over a period of 1.5 years is carried out. The maximum seabed subsidence is calculated. The monitoring system, including methods for processing and analyzing the results, is successfully implemented and can be used to solve other similar problems.
