TECHNOLOGY STATUS REPORT: A CATALOGUE OF THE HORIZONTAL ENVIRONMENTAL WELLS IN THE UNITED STATESKaback, Dawn S., Concurrent Technologies Corp., Denver, CO Ground-Water Remediation Technologies Analysis Center (GWRTAC). Report No: TS-02-01, 69 pp, 2002
The horizontal environmental well catalog has been updated approximately
every other year since 1993. This current catalog lists 1,142 horizontal
environmental wells that have been installed in the United States through the
end of the year 2000 with the date of installation, location, well purpose,
depth, construction method and materials. Though not a complete listing, this
effort serves as a record of how the industry has evolved since the late
1980s. The text provides a history of horizontal environmental well
technology; an explanation of environmental applications for horizontal wells;
discussion of well design and drilling techniques, including well materials
and drilling fluids used; and well development techniques. Trends associated
with the installed 1,142 horizontal environmental wells included in the
catalogue are also presented. Horizontal wells identified in this report have
been installed for different environmental applications: soil vapor extraction
(34%), ground-water or free-product extraction (28%), air sparging (21%),
bioremediation (5%), characterization and/or monitoring (3%), and other
[including hydraulic control] (9%). For more information, visit
