Abstract
Geodynamic processes could negatively influence development of oil and gas fields’ exploration by destructing technological processes and well constructions, transportation systems and other infrastructures. In particular, such destruction could result in lost of well construction integrity resulted in hydrocarbon fuel blows. In addition, significant and even irreparable damage could be made to the environment. Due to lack of tools for timely defining dangerous geodynamic developments, such damages are usually unexpected and very often accompanied by tremendous human and financial losses. During the last 30-35 years the methodology of regional hydrogeodeformatics as well as principles of hydrogeodeformation (HGD) field monitoring were tested and developed. They are based on the discovery of the new kind of the geophysical field of the Earth – the HydroGeoDeformation field. Special parameters characterizing stress-strain conditions within geological massifs have been developed which allow monitoring changes in these conditions at any time scale (hourly, daily, monthly, etc.) These parameters could also be used for monitoring the areal changes in deformation conditions within the huge geological regions. Therefore, the HGD monitoring provides valuable information on the areas and timing of the potential dangerous geodynamic process occurrences. The paper contains the results of HGD monitoring conducted in various regions of the Earth which allowed making predictions of potentially dangerous geodynamic conditions threatening the safety of infrastructures and personnel within the huge regions. Based on the existing experience, some practical recommendations regarding establishing HGD monitoring system and interpretations of its results are given. Their implementation would be of help in making timely strategic decisions which in many cases could prevent catastrophic consequences of dangerous geodynamic development at main oil and gas fields and transportation systems.
