HOUSTON -- May 1, 2013

Caterpillar Inc. today announced that it has developed a Dynamic Gas Blending
(DGB) retrofit kit for use on the Cat^® 3512C (HD) engine used in well
stimulation applications. Available to order in June 2013, this system will
allow for maximum substitution of diesel fuel with natural gas during high
pressure pumping operations, and is available in both Air To Air After Cooled
(ATAAC) and Separate Circuit After Cooled (SCAC) configurations for 2250 hp
and 2500 hp @1900rpm ratings.

Heavily leveraging decades of success with Cat natural gas engines and the
recent introduction of the Cat DGB system for land drilling and production,
the Cat well stimulation DGB system makes no comprise with performance,
safety, and reliability while burning a mixture of diesel and natural gas
fuels. “Through our product development work in the field with some of the
leading well servicing companies, the Cat DGB system has performed
exceptionally well. User feedback has been very positive with ease of
installation, engine performance, and the integrated safety features of the
Cat DGB system,” said Scott Roberts, Caterpillar Global Petroleum Well Service
Product Marketing Manager.

Along with the benefit of realizing significant fuel cost savings by
substituting diesel fuel with natural gas, there are several other key
features of the Caterpillar DGB system that make it a winning solution for
well stimulation. Operators can run the system with confidence on CNG, LNG,
and field gas with a lower heating value between 850 and 1,250 Btu, knowing
that the engine is maintaining United States EPA Tier 2 level emissions with
the combined muffler and Cat Diesel Oxidation Catalyst (DOC) included in the
DGB kit. The system is capable of achieving maximum substitution at various
speeds and loads over the full operating range, and will automatically adjust
to changes in gas quality without the need to perform any recalibration or
adjustments to the system during or between jobs.

The DGB system is fully integrated with the engine control system, optimizing
engine performance and ensuring that the engine always operates within safe
parameters while blending diesel and natural gas. This results in no
compromise with performance, maintenance intervals, engine reliability, and
most importantly, safety. Installation of the Cat DGB kit on existing engines
is streamlined through efficient design. The combined muffler and DOC
eliminates the need for the customer to integrate a DOC with their existing
mufflers, and a single advanced Engine Control Unit simplifies the electrical
system.

Cat Dynamic Gas Blending kits are backed by the worldwide Cat dealer network
with trained technicians to ensure service support is never out of reach. To
