The Production Facilities segment also includes our ownership interest in Independence Hub, LLC (“Independence Hub”) (Note 5). On January 18, 2019, we purchased from Marathon Oil Corporation (“Marathon Oil”) certain operating depths associated with the Droshky Prospect on offshore Gulf of Mexico Green Canyon Block 244, along with several wells and related infrastructure. As part of the transaction, Marathon Oil will pay us certain agreed upon amounts for the required plug and abandonment of the acquired assets, which we can perform as our schedules permit subject to regulatory timelines.
