FSUOGM: M25 gas leak one of worst man-made disasters in Uzbekistan's history

The hydrogen sulphide gas leak at the 25 Years of Independence (M25) gas field in September was one of the biggest man-made disasters in Uzbekistan’s history, but its consequences were dealt with quickly and effectively, Uzbek Energy Minister Jurabek Mirzamakhmudov said on October 6.

The minister said the leak was one of the six most significant incidents of its kind in the country. But it has now been contained, and efforts continue to minimise future risks at the site.

The leak, first detected on September 1 at one of M25’s wells in the Baysun district of the Surkhandarya region, was caused by a violation of the technological process during drilling operations. The high hydrogen sulphur content in the field’s gas caused severe corrosion, leading to repeated leaks. "Despite the challenges, our specialists managed to install a plug and temporarily stop the leak," he said. The site has remained operational, with safety measures a priority to prevent further incidents.

To expedite the response, international experts from Azerbaijan and the US were brought in to assist. The ongoing cleanup operation, employing advanced technology, is being closely monitored, with the final stages expected to be completed in the coming days.

On the day of the incident, Mirzamakhmudov and a team of specialists travelled to Baysun to oversee efforts and ensure the safety of the local population. "We immediately mobilised services, deploying evacuation and medical teams and provided residents with hot meals and temporary shelters," he said. A comprehensive warning system was established, with sensors continuously monitoring gas levels around the site to provide real-time updates.

The initial leak was contained by September 15, but another gas leak occurred two days later, resulting in the deaths of four workers. Public concern grew, with Uzbekistan’s Ministry of Internal Affairs and the National Guard undertaking measures to prevent widespread panic. Safety measures, including evacuation procedures and compensation for affected residents, were quickly implemented, according to Mirzamakhmudov.

Mirzamakhmudov emphasised the complexity of the conditions at the site and the high risks involved. "Continuous monitoring is required under these circumstances," he said, adding that safety remains the top priority. Despite the difficulties, the government is committed to addressing the incident while supporting the local community, he said.
