Byron Energy completes its SM58 “G” Platform installation on schedule and incident free


Byron Energy Limited (“Byron” or “the Company”), (ASX: BYE) is pleased to announce that installation of the Byron operated jacket and decks comprising the SM71 G Platform is now complete. The Triton Hedron derrick barge has de-mobilised off location after successfully installing the jacket over the SM58 G1 well (“G1”) drilled in October 2019, then driving piles and finally installing the topside facility. Byron’s operators are now living on the platform and are making final preparations to accept the drilling rig which is scheduled to arrive in two weeks. By salvaging and refurbishing a high quality structure already in good condition, the Company has realised a saving in the range of US$ 8-10 Million and has expedited cycle time to first production by 9-12 months compared to a new build facility.

Anyone who has worked in the oil industry will tell you that this is quite an accomplishment and did not happen by accident. This is the result of hard work, good planning, and dedicated professionals in our office and in the construction yard. Our cycle time to first production should be inside 12 months since we logged over 300 feet of hydrocarbon in the SM58 G1 well. I am extremely pleased with this effort and proud to be a part of the Byron team. – Maynard Smith, Byron’s CEO

The next phase of the SM58 project is to lay the oil and gas sales pipelines needed to transport produced hydrocarbons to market. The pipeline lay barge was mobilized on Friday, 3 July and arrived on location Saturday, 4 July. Initial operations comprise the installation of the 4-inch diameter 1,000- foot (305 metre) oil sales line. Once the oil line portion of the project is complete, the barge will begin laying the 8-inch diameter 39,000-foot (12 km) gas sales line. Pipeline laying and tie-in operations are expected to take approximately 50 days depending on weather conditions.

The Enterprise 264 jack up drilling rig is scheduled to mobilize to the SM58 G platform by 20 July and begin completion operations on the G1 well. The drilling rig will be used to disconnect the G1 from the mudline hanger, tie it back to the platform and then complete the Upper O Sand for production. The Upper O Sand will be perforated and sand control will be placed in the wellbore. The G1 completion operations are expected to take approximately 30 days due to the complexity of tying back the casing to surface. Additional topside work will be required after the completion operations to connect the wellhead into the platform flowlines. Without significant weather delays, first production from the G1 is expected by 1 September 2020
