Modelling atmospheric dispersion during oil and gas extraction activities L.J. Mata Institute de Mecdnica de Fluidos, Universidad Central de Venezuela, Venezuela ABSTRACT There exists a great interest to evaluate the environmental impact every time that a accident occurs. This phenomenon are transient in their behaviour and in general very dangerous to nature. Field observations show that emergency planning may not be reliable if only if a single wind observation is made, and can often be completely unreliable if the wind observation site is located 10 Km or more from the hazardous gas release point. As an alternative to a full three-dimensional model, many engineers and researchers are using puff models based on wind fields derived from interpolated wind observations. The concentration downwind of the source or sources is estimated using a gaussian puff trajectory model for non-dense emmissions. The model can also handle multiple receptors. It is not expected to be valid for very
