This universe is on the threshold - Whether to survive or diminish on account of pollution and imbalances which are created by people themselves. There is threat to ecology on account of all pollutions. For all of the benefits oil has brought to modern society, risk is inherent. Protecting the environment while producing, transporting, refining and marketing fuel is a challenge the petroleum industry must meet every day.

Oil spill cleanup is an expensive operation. Conventional processes for monitoring oil spills are tedious, inexact, and time consuming. GIS offers a solution to this problem by providing analysis and visualization capabilities.

A geographic information system (GIS) is useful in responding to oil spills because it can integrate a large amount of marine, coastal, and oil production/transportation data. The key to making use of the GIS is collecting and maintaining critical data, such as wind speed, wind direction, ocean current direction, density, and pH in data bases, so that it is available in case of a spill. Once spill has occurred; these preexisting data-bases are queried, and the vector maps are analyzed to see what the major concerns are.

This paper envisages our model for an offshore field along the east coast of India. Using GeoMedia Professional for analysis in this fragile environment with unpredictable climatic conditions, we process available data - physical parameters and chemical parameters - to predict the extent and location of a spread.

This methodology in general may be useful to predict oil spill movement of any coastal region. This capability enables us to prepare for oil spills and respond more quickly, thereby minimizing the damage to the environment. Thus GIS can be used as an excellent decision-support tool for contingency planning, risk assessment, and remedial operations.
