An onshore gas well blow-out and its impact observations using satellite data

The blow-out of the ONGC Gas Well-19 located at Pasarlapudi in East Godavari District, Andhra Pradesh, attracted lot of concern on its impacts. The blow-out site has been monitored by satellite-based data sets from Indian Remote Sensing Satellite (IRS-P2) and Landsat-5 for impact assessment studies....

Description
Summary:The blow-out of the ONGC Gas Well-19 located at Pasarlapudi in East Godavari District, Andhra Pradesh, attracted lot of concern on its impacts. The blow-out site has been monitored by satellite-based data sets from Indian Remote Sensing Satellite (IRS-P2) and Landsat-5 for impact assessment studies. The satellite data sets showed signature variation in 200 m surrounding the well site. The water umbrella formed over the blow-out site and the resultant temperature and humidity variation measured on the ground were significant up to 200 m radius. Satellite-based optical data have been used for estimating the well temperature. The gas well temperature estimated from satellite data has been found to be around 1100°C. The methodology adopted for estimating the gas well temperature and the results on impact assessment studies are discussed.
