A subterranean barrier and method for forming same are disclosed, the barrier including a plurality of casing strings wherein at least one casing string of the plurality of casing strings may be affixed to at least another adjacent casing string of the plurality of casing strings through at least one weld, at least one adhesive joint, or both. A method and system for nondestructively inspecting a subterranean barrier is disclosed. For instance, a radiographic signal may be emitted from within a casing string toward an adjacent casing string and the radiographic signal may be detected from within the adjacent casing string. A method of repairing a barrier including removing at least a portion of a casing string and welding a repair element within the casing string is disclosed. A method of selectively heating at least one casing string forming at least a portion of a subterranean barrier is disclosed.

Subterranean barriers, methods, and apparatuses for forming, inspecting, selectively heating, and repairing same

Systems, components, and methods relating to subterranean containment barriers. Laterally adjacent tubular casings having male interlock structures and multiple female interlock structures defining recesses for receiving a male interlock structure are used to create subterranean barriers for containing and treating buried waste and its effluents. The multiple female interlock structures enable the barriers to be varied around subsurface objects and to form barrier sidewalls. The barrier may be used for treating and monitoring a zone of interest.

Method of installing subsurface barrier

A containment system for use adjacent to a selected region of a subterranean formation and comprising a plurality of laterally interlocked casing strings. At least one electrically conductive element is disposed along at least a portion of a casing string and is used for performing electrical time domain reflectometry. At least one protective element may be positioned between portions of adjacent casing strings of the barrier, and at least one electrically conductive element may be disposed at least partially within the at least one protective element for use in indicating at least one characteristic of at least a portion of the containment system. Electrical time domain reflectometry (TDR) may be used to indicate the at least one characteristic; for instance, TDR may be used to indicate leakage through the barrier or a discontinuity or void in a barrier filler material.

Methods for indication of at least one subsurface barrier characteristic and methods of use

Method of sealing casings of subsurface materials management system

Subterranean barriers including at least one weld

Processes and methods relating to treating contaminants and collecting desired substances from a zone of interest using subterranean collection and containment barriers. Tubular casings having interlock structures are used to create subterranean barriers for containing and treating buried waste and its effluents. The subterranean barrier includes an effluent collection system. Treatment solutions provided to the zone of interest pass therethrough and are collected by the barrier and treated or recovered, allowing on-site remediation. Barrier components may be used to in the treatment by collecting or removing contaminants or other materials from the zone of interest.

Method of in situ retrieval of contaminants or other substances using a barrier system and leaching solutions

Subsurface materials management and containment system

A tunneling system including a tunneling apparatus including a cutting structure for forming a borehole and at least one linkage section for transmitting a force generally toward the cutting structure is disclosed. A method of disposing a casing string within a subterranean formation by applying a force generally to the trailing end of the tunneling apparatus, generally toward the leading end thereof, but without transmitting the entire force through the entire casing string is also disclosed. At least one linkage section extending within but not in contact with at least one casing section of the casing string may transmit the force. Also, a force limiting member may limit a force applied to the casing string.
