Pakistan Petroleum Limited (PPL) is preparing to contain and extinguish a persistent fire that erupted during borehole drilling in Karachi’s Korangi Creek area. Chemical analyses of soil and groundwater samples have revealed elevated levels of gases and minerals, prompting plans for gas exploration in the vicinity

Incident Overview

The fire began last month during drilling operations near an oil refinery in Korangi Creek. Initial assessments suggested the presence of shallow gases that might dissipate naturally. However, the sustained intensity of the flames over eight days has led experts to recommend active intervention.

Chemical Analysis Findings

Recent reports indicate significant concentrations of hazardous substances in the area:​

  • Benzene: Detected at 19 micrograms per liter, surpassing the permissible limit of 5 micrograms per liter.
  • Toluene: Measured at 15 micrograms per liter, exceeding the allowable 5 micrograms per liter.​
  • Tetrachloroethane: Found at 33 micrograms per liter, well above the safe threshold of 5 micrograms per liter.​

Additionally, elevated levels of heavy metals such as iron, arsenic, manganese, and lead have been identified.

Planned Actions

In response to these findings, PPL, in collaboration with experts, will undertake measures to extinguish the fire. Following containment, a gas exploration initiative will be launched to assess the extent of gas presence within a five-kilometer radius. This approach aims to ensure public safety and evaluate potential resource opportunities.

Conclusion

The ongoing situation at Korangi Creek underscores the complexities associated with drilling operations in areas with potential underground gas pockets. PPL’s proactive measures reflect a commitment to addressing immediate safety concerns while exploring the broader implications of the incident.
