Patent ID: 11725850

Abstract:
A multivessel system is provided for installing a production train in an ultra-deep borehole into the Earth's lithosphere. The system includes a plurality of gate valves and a plurality of pressure vessels, including a first pressure vessel having a first vessel elevator configured to engage and hold a production train section as the first vessel elevator moves in the first pressure vessel along a portion of a length of a train channel, a second pressure vessel having a second vessel elevator configured to engage and hold the production train section as the second vessel elevator moves in the second pressure vessel along another portion of the length of the train channel, and a third pressure vessel, with all three pressure vessels being configured to be water cooled. The system includes a train clamp configured to engage and hold the production train in the borehole. Each of the first vessel elevator and the second vessel elevator includes a clamp configured to engage and hold the train section as the respective first vessel elevator or the second vessel elevator moves along the train channel.
