CONDITION OF TENGRATILA GAS FIELD

CONDITION OF TENGRATILA GAS FIELD
The Environmental Impact Assessment of Chhatak-2 (Tengratila) Gas Field Blowout is very much indispensable to identify the actual impacts on either of environmentally, socially, economically or culturally. EIA has been conducted employing questionnaire for field survey, laboratory based analysis for knowing water quality and Matrix and Ranking Checklist for final stage of the report. For predicting the overall impacts, the surrounding environment has been assessed under two major headings: (I) Socio-Economic Impacts and (II) Ecological Impacts. At last, vulnerability assessment and cumulative impact assessment is very much necessary to identify ultimate overall impacts on the surrounding environment due to explosion. The ultimate result of the explosion on Socio-Economic conditions of the study area was very much severe. The Socio-Economic value of the blowout area have been decreased that means the Socio-Economic conditions of the study area have been negatively affected. It has been found that almost all of the inhabitants of the Tengratila and Ajabpur villages were in vulnerable condition due to horrific problems such as noise, earthquake, heat, ash, sound, gas and fire at the blowout stage from 14 to 25 days. It has been calculated that Tengratila gas field explosion has destroyed the surrounding environmental components of the study area. The ranks of the impact at blowout stage due to different causes are noise-1.76, fire-7.18, ash-6.43, gas-6.72 out of 10 where fire was the main cause of the severe impact and overall-6.73 which is the severe impact on the environment because almost about 67% of the surrounding environment have been affected by explosion.

Since the mining and environment have become complementary to each other and thus neither can be separated nor ignored in the interest of the development of the country, so environment friendly mining is mandatorily required for the improvement of physico-chemical, biological and social environment.
