(B) reservoir characterization, monitoring, 
and modeling; 
(C) stress mapping;

(2) ENHANCED
GEOTHERMAL
SYSTEMS
RES-
ERVOIR STIMULATION.— 
(A) PROGRAM.—In collaboration with in-
dustry partners, the Secretary shall support a 
program of research, development, and dem-
onstration of enhanced geothermal systems res-
ervoir stimulation technologies and techniques. 
A minimum of 5 sites shall be selected in loca-
tions that show particular promise for enhanced 
geothermal systems development. Each site 
shall— 
(i) represent a different class of sub-
surface geologic environments; and 
(ii) take advantage of an existing site 
where subsurface characterization has been 
conducted or existing drill holes can be uti-
lized, if possible.

CONSIDERATION
OF
EXISTING 
SITES.—The following 2 sites, where Depart-
ment of Energy and industry cooperative en-
hanced geothermal systems projects are already 
underway, may be considered for inclusion 
among the sites selected under subparagraph 
(A): 
(i) Desert Peak, Nevada. 
(ii) Coso, California. 
SEC. 4207. GEOTHERMAL ENERGY PRODUCTION FROM OIL 
AND GAS FIELDS AND RECOVERY AND PRO-
DUCTION 
OF 
GEOPRESSURED 
GAS 
RE-
SOURCES. 
(a) IN GENERAL.—The Secretary shall establish a 
program of research, development, demonstration, and 
commercial application to support development of geo-
thermal energy production from oil and gas fields and pro-
duction and recovery of energy from geopressured re-
sources. In addition, the Secretary shall conduct such sup-
porting activities including research, resource character-
ization, and technology development as necessary. 
(b) GEOTHERMAL ENERGY PRODUCTION FROM OIL 
AND GAS FIELDS.—The Secretary shall implement a 
grant program in support of geothermal energy production 
from oil and gas fields. The program shall include grants

for a total of not less than three demonstration projects 
of the use of geothermal techniques such as organic 
rankine cycle systems at marginal, unproductive, and pro-
ductive oil and gas wells. The Secretary shall, to the extent 
practicable and in the public interest, make awards that— 
(1) include not less than five oil or gas well 
sites per project award; 
(2) use a range of oil or gas well hot water 
source temperatures from 150 degrees Fahrenheit to 
300 degrees Fahrenheit; 
(3) cover a range of sizes up to one megawatt; 
(4) are located at a range of sites; 
(5) can be replicated at a wide range of sites; 
(6) facilitate identification of optimum tech-
niques among competing alternatives; 
(7) include business commercialization plans 
that have the potential for production of equipment 
at high volumes and operation and support at a 
large number of sites; and 
(8) satisfy other criteria that the Secretary de-
termines are necessary to carry out the program and 
collect necessary data and information. 
The Secretary shall give preference to assessments that 
address multiple elements contained in paragraphs (1) 
through (8).
