Baden/Vienna, March 27, 2007 (euro adhoc) - C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78), one of the leading providers of oil and gasfield
services in Russia and Kazakhstan, has been awarded a major contract
for 567 hydraulic fracturing jobs through its operating subsidiary
CATKoneft. The contract’s implementation will start on April 1, 2007.
With proven oil and gas reserves of 18.9 billion barrels and an oil
and gas production of 1.7 million barrels per day, Rosneft is the
largest oil producer in Russia. Since July 2006, the company is
publicly listed at the London and Moscow Stock Exchange. In 2005
Rosneft generated revenues of more than USD 24 billions. The
hydraulic fracturing jobs will be rendered in the area of Yugansk.
CATKoneft has been operating there since 2002 and has since then
performed more than 420 frac jobs for Rosneft’s production entity
Yuganskneftegaz. Due to this longtime experience in this area,
CATKoneft is very familiar with the specific challenges within
Yugansk’ oil and gas fields. Due to the geological structure
hydraulic fracturing operations in the Yugansk region are more
sophisticated than average frac jobs and therefore profitable for
C.A.T. oil. Typically, a frac job is measured by the amount of
proppant pumped into the fracture. An average frac job in Russia
usually requires 40 to 50 tons of proppant. In Yugansk, on average,
100 tons are needed to complete one single operation. "This
three-year-contract underscores our strong partnership with the major
oil and gas producers in Russia. Our high operative standards and
high-tech equipment enable us to perform demanding and large fracs
quickly and efficiently. As a result, we manage to continuously
increase utilization capacities", said Manfred Kastner, Chief
Executive Officer of C.A.T. oil AG.

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 in Baden near Vienna and employed 2,230 people
at the end of 2005, 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.
