Abstract

All industrialized countries face the challenge to combine long term, low cost energy supply and continuous reduction of their environmental impact from the energy production. Therefore the strategic target of implementation of HSE standards is sustainable and environmentally sound development and use of the Earth energy resources. The main goal of our research is development of a new environmental management methodology supported by software tools for implementation of ISO-14000 environmental standards in real oil and gas operations.

On one hand the environmental management methodology has to be generic, on the other hand the proposed methods of environmental impact assessment must be applicable for each specific situation. We have reinterpreted the ISO environmental monitoring model in terms of remote sensing survey and GIS models.

Besides storage of the scalable earth surface and underground information, the methodology and suggested software tools allow modeling the interaction between the engineering objects and the environment during full life cycle of oil and gas fields starting from their exploration until their abandonment.

The remote sensing methods reviewed in the article as well as the suggested methodology can be applied for wide range of targets in different regions. It can be monitoring of pipelines in the North See or Mexican Gulf, control of pipeline security or vegetation degradation in tropical countries as well as monitoring of oil operations in remote arctic locations.

Introduction

Protection of the environment, health and safety of citizen, sustainable and economically effective exploitation of domestic natural resources are the key issues of the economic policy of most industrially developed countries. The international Health, Safety and Environment (HSE) regulations have been finalized in the ISO-14000 standards. The United Nations Conference on Environment and Sustainable Development (UNCED) as well as International ExpertMeeting on Environmental Practices in Offshore Oil and Gas activities (ref. Technical Background document,1997) emphasized the significance of implementation of the international environmental standards and innovation of environmental monitoring systems in oil and gas operations.

However oilfield oriented database management (or monitoring) systems, currently available on the market, contain mainly (or only) exploration and production (E&P) inventory databases. They do not include any environment, health or safety related parameters or functions. Moreover, in spite of tremendous achievements in information technologies (such as GIS, RS, Internet) reached for the last five years, there is still little (or no) progress in development of oil and gas environmental management systems and even E&P data bases. Consequently the technical level of the commercially available E&P information systems is dramatically lower than the modern average level of the information technologies. Therefore development of an oil and gas environmental management system (OGEMS) is of both industrial and environmental importance and has urgent demand on the software market.

OBJECTIVES

In last years there have been numerous cases of largescale environmental damages caused by oil and gas field developments. They involve contamination of surface, underground and marine water, agricultural soils, air pollution, etc.
