JAKARTA, NETRALNEWS.COM - Pertamina Hulu Energi Offshore Northwest Java (PHE ONWJ) continues to intensify the drilling of relief well YYA-1 RW to be able to immediately stop gas bubbles that occur around the YYA-1 well. Until now, drilling has reached a depth of 1,464 meters, or more than 4,000 feet from the target of 2,765 meters or around 9,000 feet

Ifki Sukarya, VP Relation of PHE ONWJ, confirmed that drilling has been carried out since August 1, 2019 using the Soehanah rig, and is getting closer to predicting leakage at the YYA-1 well.

"Drilling a relief well or new well (YYA-1RW) is to inject fluid in the form of heavy mud so that the YYA-1 well can be permanently closed," said Ifki.

He added that relief well drilling was carried out by installing casings with a diameter of 17-1/2".

As is known, PHE ONWJ succeeded in accelerating the Relief Well YYA-1RW drilling drill in an effort to stop gas bubbles after one week of conducting surveys to determine the well points and rig placement. This rig stands about 1 kilometer from the YY platform, where the YYA-1 well is located. Drilling of the well began at 14.00 West Indonesia Time on Thursday (1/8), or 2 days ahead of the original schedule.

Previously, Rig Up Jack Soehanah was around the location of the YYA-1RW relief well on July 27, 2019.

The rig mobilization activities are carried out in conjunction with geohazard and geotechnical surveys, so there is no waiting time.

The pre-load process can be carried out immediately once the Marine Survey Waranty is obtained. Meanwhile, preparatory work can be done simultaneously so as to accelerate the two-day pledge from the original plan.

PHE ONWJ cooperates with experienced companies in the field of well control that have proven successful in handling the same thing, including events in the Gulf of Mexico.

"Despite the problems that are currently happening at PHE ONWJ on a much smaller scale, but to ensure optimal handling, we partner with other experienced companies to help and conduct joint studies related to handling situations like this.

The company continues to work optimally to prevent oil spills from spreading to wider waters by implementing a layered protection strategy around the platform and chasing, localizing, and siphoning oil spills that crossed the oil boom belt boundary around the platform.
