A fire that started during a borehole mine in Korangi Creek, Karachi, continues to burn six days later after drilling reached a depth of 1,200 feet.
Firefighting efforts were suspended on Saturday due to extreme heat, making it unsafe for responders.
Authorities have collected water and sand samples for chemical testing to analyze the gas type and concentration in the underground reservoir.
Meanwhile, geologist Dr. Adnan Khan from the University of Karachi pointed to over five decades of exploration data, suggesting that methane gas and possibly coal deposits exist in the area.
He explained that the fire erupted when drilling raised temperatures, releasing methane, a highly flammable gas. Experts warn that gas emissions at the site exceed 15%, necessitating immediate safety measures.
Korangi Creek’s 25-million-year-old rock formations contain natural water reserves and methane, hinting at potential hydrocarbon resources. A 2020 Chinese study also identified gas and coal layers in the region.
However, structural faults and fractures allow gas to escape to the surface, fueling the ongoing fire. Dr. Khan cautioned that the fire could persist for weeks, posing health risks to nearby residents due to continued carbon dioxide emissions
