Baden/Vienna (euro adhoc) - September 28, 2007 - C.A.T. oil AG (O2C,
ISIN: AT0000A00Y78), one of the leading providers of oil and gasfield
services in Russia and Kazakhstan, further advances its
diversification process and geographical expansion by launching
international operations in India, Nigeria and Latin America through
its new subsidiary CAToil-GEODATA.

CAToil-GEODATA provides high-margin geotechnical services such as
2D/3D seismic and reservoir engineering to Russian and international
oil and gas majors. In addition to its strong market position in the
Russian oil and gas industry, the Company faces increasing demand
from customers abroad.

C.A.T. oil has successfully entered new markets and has recently been
awarded with new contracts from international customers with an
overall volume of EUR 15 million. These include 2D/3D seismic
projects in India and Nigeria. Mobilization will start in Q4 2007 and
will be completed within H1 2008. Additionally, the Company has
already launched a consultancy project for an European oil and gas
major in Argentina to optimize client´s local oil and gas production.
Surveys and interpretation of comprehensive seismic data will be
conducted in the CAToil-GEODATA research centers in Russia.

Manfred Kastner, CEO of C.A.T. oil AG, outlined: "In view of scarcity
of energy reserves the systematic collection and interpretation of
seismic data are getting more and more important for the global
production of oil and gas. As a consequence, the geotechnical service
sector is facing increasing demand and strong growth. With clear
double-digit margins CAToil-GEODATA´s high-quality seismic and
reservoir engineering services represent a lucrative and important
enhancement of our service portfolio. Through this product
diversification we gain additional strategic access to important new
customers and markets and thus accelerate the geographical expansion
of C.A.T. oil."

About C.A.T. oil AG: Austria-based C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78) is one of the leading providers of oil- and gasfield
services in Russia and Kazakhstan. C.A.T. oil´s core business is
hydraulic fracturing, a process which helps to open up oil- and
gas-bearing rock formations in order to increase or even enable oil
and gas production. The C.A.T. oil crews use state-of-the-art methods
and technologies to generate high pressure in the oil or gas
reservoirs concerned. This pressure causes cracks to appear in the
rock through which oil or gas can be produced in larger quantities
from the production well, and hence efficiently boosts extraction,
particularly in the case of deposits that are difficult to develop or
low-output wells. In addition, hydraulic fracturing can be used to
revitalize wells that have previously been idle.

The Company has its headquarters Baden/Vienna and employed an average
of 2,875 people in the first half of financial year 2007, most of
whom are based in Russia and Kazakhstan. Customers include leading
oil and gas producers such as Gazprom, KazMunaiGaz, LUKOIL, Rosneft,
and TNK-BP. C.A.T. oil has been listed in the Prime Standard of the
Frankfurt Stock Exchange since May 4, 2006, and has been a member of
the SDax since September 18, 2006.
