The head of the Riau Energy and Mineral Resources Agency (DESDM), Indra Agus Lukman, said that the gas jet hole has now reached six meters in diameter.
“The diameter of the hole has actually increased to six meters. Because the texture of the ground above it when there is gas and turbulent water, it will automatically have an effect. However, since the height of the gas explosions have been drastically reduced, “Indra said when interviewed by Kompas.com on Sunday.
According to Indra, the well is planned to be closed with cement in the next two days.
“If the flow decreases, of course it will be easier to cover it with cast cement. But if it becomes strong again, we close it, the gas spills from the sides, ”said Indra.

Furthermore, he continued, the current state of gas explosions no longer has the potential to explode, because the Lower Explosive Limit (LEL) is already zero. The same happens with H2S or the toxic content of the gas disappears.
However, Indra appealed to remain vigilant. Because the LEL condition can sometimes be zero, it can sometimes increase.
“We still have to be vigilant. Our measurement this afternoon was zero. But sometimes there is, which means there is still movement underneath,” Indra said.
