Class Information
Number: 166/350
Name: Wells > Submerged well > Submerged, buoyant wellhead or riser
Description: Process, apparatus, or device involving use of a device at the top of the well, positioned above the surface of the earth, adapted to cap the well, support the structure inside a well casing, regulate the operation of the well, and/or supply well fluid for distribution; or involving use of a device extending upwardly from the plane where the well meets the surface of the earth toward the surface of the water for fluid communication with the surface of the water, which device includes portions lighter than the water displaced thereby to assist in supporting the adjacent well structure against gravity.
