DEFINITION

Classification: 166/335

SUBMERGED WELL:

(under the class definition) Process, apparatus, or device including a step of, or means for, assembling the components of a well or including the component parts of such a well, the discharge surface of which well is located below the surface of a body of water.

(1) Note. The well of this subclass is located below the surface of an ocean, a lake, a river, etc.

(2) Note. For inclusion in this subclass characteristics must be claimed to peculiarly limit the process, apparatus, or device to function with or as a well, the surface of which is below the surface of a body of water.

(3) Note. In this and the indented subclasses the terms at the end of this subclass definition will be used as defined herein (terms followed by an asterisk (*) have been so defined).

SEE OR SEARCH THIS CLASS, SUBCLASS:

75.11+, for above ground apparatus generally, including a wellhead structure. A wellhead structure disclosed as being

under water but not claimed is made to a feature peculiarly adapting the device to function under water is to be found in subclasses 75.1+.

SEE OR SEARCH CLASS 37, Excavating,

307+, for apparatus adapted to dredge material from a submerged location.

114, Ships, for a floating vessel generally including a floating vessel which may be utilized in construction of a submerged well.

175, Boring or Penetrating the Earth,

5+, for a process of, or apparatus for, boring a submerged formation.

299, Mining or In Situ Disintegration of Hard Material, for mining or disintegrating hard material in a submerged location.

405, Hydraulic and Earth Engineering, for subject matter not including well structure directed to apparatus adapted to function in a submerged location, particularly

158+, for a process of, or apparatus for, laying pipe or cable into a submerged location; and subclasses 195+ for floatable marine floor-supported structure including a submerged well platform.

FLOW LINE:

A tubular member adapted to transmit well fluid* away from the well.

RISER:

Structure for use with a submerged well intended to extend from the wellhead* toward the surface of the water generally directly above the wellhead. WELL ELEMENT:

Any individual portion of well structure.

WELL FLUID:

The desired fluid material of the earth. The purpose of the well is to remove this fluid.

WELLHEAD:

Means at the top of the well, generally extending above the surface of the earth, adapted to cap the well, support the

well structure* inside a well casing, regulate the operation of the well, and/or supply well fluid* for distribution.

WELL STRUCTURE:

Equipment added to the earth in the formation or use of a well. Well structure may extend above the surface of the earth (see wellhead*) as well as laterally away from the well (see flow line*).
