Lapindo Brantas Inc. shut-in (manually turn off the well) to the Tanggulangin well (TGA) 5 after the distribution pipeline leak to the gas plant at TGA 3. Even so, Lapindo Brantas Inc, guarantees that the gas supply for residents is not disrupted because it is diverted to the TGA 1 well and TGA 2.
"Even though there are wells that have to be shut-in, the supply for the Gas Network program has not been disrupted. We supply gas from other wells. "We are currently preparing to repair the leaky pipe so that the TGA 5 well will start producing again," said Vice President Operations of PT Lapindo Brantas Inc Harsa Harjana.
The explanation was conveyed following residents' concerns that the gas supply for the Gas Network program would experience disruption. As is known, Pertagas is completing the Gas Network program of around 3,850 house connections (SR) for residents of Tanggulangin, Sidoarjo. Gas for the Gas Network program is taken from the Lapindo Brantas well at Tanggulangin.
Harsa explained that the leaking pipe was under the river that flows in Kalidawir Village. The provisional estimate is that the leaking pipe is at the end of the pipe under river water, at a depth of 2 meters from the river bed to be precise. Harsa explained that the pipeline leak occurred last Friday (15/10), around 22.00. At that time Marsam, a Kalidawir resident, saw a bubble and water coming out of the water along with mud from the river.
"Because the leaking pipe is at the bottom of the river, a bubbling appears and water bursts with mud from the riverbed which is carried by the gas looking for a way out," said Harsa Harjana.
Receiving the report, Chusnul Maab, Production Operator of Lapindo Brantas checked the pressure of the TGA 5 well. From the data in the Gas Flow Computer, it can be seen that the gas pressure has indeed dropped, which indicates a gas pipeline leak.
Therefore, the TGA 5 well shut-in was immediately carried out. In less than 30 minutes, the gas flow could be stopped to minimize the risk. Around 23.00 the bubble and water mixed with mud that had been gushing had stopped completely.
"Lapindo would like to thank Mr. Marsam who was immediately responsive in reporting so that the pipeline leak could be handled immediately.
This shows that communication between Lapindo and residents has been well established, "he said.
He explained, at that time Lapindo Brantas was indeed sending 10 MMcsf of gas as requested by Pertagas Niaga. At that time the pressure should be 570 psi, but on the screen, the pressure is only 278 psi.
"So because the leak is fine, the leak does not directly affect the safety valve in the TGA 5 well so there is no automatic shutdown," he said.
When met separately, Kalidawir Village Head M Anas asked Lapindo to immediately repair the leaking pipe. The reason is that the pipe is very important to carry gas. " Because the damage has occurred, it should be replaced with a new pipe, "he said.
According to Anas, if repairs are not carried out immediately, it will increase residents' unrest. Apart from waiting for this gas for a long time, now do not expect the gas to be disrupted by pipeline leaks.
"We ask to be repaired immediately, replace the pipe with a new one, passing through a safe location. Hopefully, this gas will also be realized soon and it will not be delayed any longer.
