centrifugal pump, a progressing cavity pump, or any suitable
equipment and combinations thereof for providing the fluid 112 to
the wellbore 108 such as under pressure or the like, as will be
appreciated by those skilled in the art.
[0023] In an embodiment, best seen in FIG. 2, a system is indicated
generally at 200. The system 200 comprises a prime mover 202 that
is a turbine engine having a compressor section 204 and a turbine
or turbo expander section 206. Air is introduced to the prime mover
202 at an inlet 208 and may be routed through an air heat exchanger
210. The air heat exchanger 210 may be utilized to cool the
incoming air into the prime mover 202. The air is directed from the
heat exchanger to the compression section 204 of the prime mover or
turbine engine 202. The compression section 202 may have a
plurality of compression stages and the air may be routed through
at least one intercooler 212 between or after one or more of the
compression stages. The compressed air exits the compression
section 204, is mixed with fuel from the fuel source 104, is

and routed through the turbine or expander section 206 of the
engine 202. The turbine or expander section 206 may include a
plurality of expansion stages and exhaust gas may be routed from
the final stage or an intermediate stage in an exhaust gas outlet
to an auxiliary heat exchanger 216 for use with an auxiliary
system, such as the auxiliary system 118. An output 218, such as a
shaft, of the prime mover 202 is connected to an input (not shown),
such as a shaft, of the driven device or devices, such as the pump
106 or the like, by a direct or closed coupled connection, a
transmission, a gear reducer, a power turbine close coupled to the
pump or by any suitable connection.
[0024] As noted above, the pump 106 or driven device is in fluid

112, such as a working or treatment fluid, including, but not
limited to, a fracturing fluids, proppant(s), acid(s), cement
slurries, gravel pack mixtures, drilling fluids, completion fluids,
and combinations thereof.
[0025] The auxiliary system 118 may utilize the auxiliary heat
exchanger 216 as a steam generator 122 for generating steam and
operating a combined cycle system, such as by operating a steam
turbine with a suitable output or the like, as will be appreciated
by those skilled in the art. The auxiliary system 118 may utilize
the auxiliary heat exchanger 216 as an evaporator for a working
fluid, such as the fluid 112, the fluid 114, the fuel source 104,
or the like.
[0026] The auxiliary system 118 may utilize the auxiliary heat
exchanger 216 as a heat source to heat the fluid 112 to, for
example, control the chemical reactions and/or characteristics of
the fluid or treatment fluid 112. The heated treatment fluid 112
may be routed to the wellbore by a suitable pumping and/or plumbing
arrangement, such as the pump 106 and treating iron 110.
[0027] The auxiliary system 118 may utilize the auxiliary heat
exchanger 216 as a heat source to heat the fluid 114, such as
produced fluid from the wellbore 108 or an adjacent wellbore or
facilities. The produced fluid 114 may be conditioned or otherwise
treated prior to being evaporated or boiled off as part of the
auxiliary system 118 or the conditioned or treated fluid 114 may be
injected into the turbine or expander section 206 of the prime
mover 202 or injected into the air inlet 208 of the prime mover 202
to provide cooling.
[0028] The auxiliary system 118 may utilize the auxiliary heat
exchanger 216 to heat the supercooled gas from the LNG fuel source
504 or the CNG fuel source 502 prior to injection into the prime
mover 102, as will be appreciated by those skilled in the art. The
auxiliary system 118 may utilize the auxiliary heat exchanger 216
as the heat input of a waste heat driven refrigeration system 120,
which may then be utilized to, for example, cool the incoming air
in the air heat exchanger 210, such as at the inlet 208 of the
prime mover 202, to operate a mechanical chiller system or the like
to cool various components of the system 100.
[0029] In an embodiment of a system 100' shown in FIG. 3, the
auxiliary system 118 may further utilize cooling water from a
cooling water system 302 of the prime mover 102 or 202 as a heat
source for the auxiliary heat exchanger 216 for use with the fluid
112, the fluid 114, the fuel source 104 (such as the LNG fuel
source 504 or the CNG fuel source 502), the refrigeration system
120, the steam generator 122, and the air heat exchanger 210. The
system 100' may utilize only cooling water from the. cooling water
system 302 as a heat source for the auxiliary heat exchanger 216.
The systems 100 and 100' may utilize heat from an auxiliary cooling
system, the cooling water system 302, the exhaust gas system 116,
and combinations thereof, as will be appreciated by those skilled
in the art.
[0030] The air heat exchanger 210 may be utilized to cool and/or
heat the incoming air at the inlet 208 and heat the supercooled
natural gas from, for example, the CNG fuel source 502 or the LNG
fuel source 504 prior to injection into the prime mover 102 or 202.
The natural gas from the air heat exchanger 210 may then be routed
to the auxiliary heat exchanger 216 to heat the gas from the air
heat exchanger 208 outlet prior to injection, such as at the
combustor 214 into the prime mover 202 or 102.
[0031] The fluids 114 may comprise fracturing fluids, proppant(s),
acid(s), cement slurries, gravel pack mixtures, drilling fluids,
completion fluids, and combinations thereof, as will be appreciated
by those skilled in the art. The fluid or fluids 114 may be
utilized in any number of well servicing operations including, but
not limited to, a fracturing operation, an acid treatment
operation, a cementing operation, a well completion operation, a
coiled tubing operation, a sand control operation, and combinations
thereof.
[0032] The pump or driven equipment 106 may comprise a pair of
pumps arranged to be driven by a single prime mover 102 or 202,
such as those disclosed in commonly assigned and copending
application Ser. No. 12/203,604 filed Sep. 3, 2008 and incorporated
by reference herein in its entirety.
[0033] The prime mover 102 or 202 may further comprise a noise
reduction system 124. The noise reduction system 124 may be coupled
to or in suitable communication with the exhaust system 116 of the
prime mover 102 or 202 and may comprise a diversion for the exhaust
gas downstream of the auxiliary heat exchanger 216 such that the
exhaust gas is directed upwardly. The noise reduction system 124
may comprise a "noise canceling" or counteracting wave directed at
a noise source, such as the exhaust gas of the prime mover 102 or
202 to reduce the effective noise of the prime mover 102 or 202 or
other surface equipment noise sources and thus reduce the total
overall noise of the entire system 100. The auxiliary heat
exchanger 216 itself may function as a silencer or noise reducer by
routing the exhaust gas through baffles and the like.
[0034] The particular embodiments disclosed above are illustrative
only, as the invention may be modified and practiced in different
but equivalent manners apparent to those skilled in the art having
the benefit of the teachings herein. Furthermore, no limitations
