July 20, 2006 - Austria-based C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78), one of the leading providers of oilfield services in
Russia and Kazakhstan, has started to operate one used fracturing
fleet that was acquired during the first quarter of 2006 following
its entire technical overhaul. This brings the number of fracturing
fleets currently in use by the company to nine. Since being deployed,
the new fleet has been operating in an oilfield of one of the major
customers of C.A.T.oil, where it is now stationed permanently. This
additional capacity has enabled C.A.T.oil to extend its contract with
this customer for further 14 fracturing jobs to be performed in the
month of July 2006. The new fleet has therefore contributed to group
sales since the end of the second quarter. Also C.A.T.oil expects to
perform more jobs in the future than have been contracted to date.
Overall, the number of fracturing jobs in the second quarter was very
satisfying. Not least to its new active fleet and based on current
perception, C.A.T.oil performed the highest number of fracturing jobs
per quarter in the entire history of the company between April and
June 2006. The company plans to release its second quarter results at
the end of August. The new fleet is providing services in C.A.T.oil’s
core business of hydraulic fracturing. Among other equipment, the
fleet comprises five pumping units which the company uses to pump
liquids under high pressure into the oil- and gas-bearing rock
formations. This process fractures the rocks and enables a sustained
increase in the well flow rate and output. Before the used fleet
could be put into operation, extensive servicing and modifications
were carried out to tailor it to the special requirements of C.A.T.
oil AG. Because the company is principally active in the severe
weather conditions of Western and Eastern Siberia, all fleets
deployed have to meet highest technical requirements and be extremely
flexible and robust. As already announced, the company has ordered
three additional new fleets. Equipment for these fleets is currently
being delivered to C.A.T.oil’s maintenance facilities in Western
Siberia. Manfred Kastner, CEO of C.A.T.oil AG, said: "Demand for our
services is constantly growing. Thanks to our newly commissioned
fleet and the three additional fleets that will boost our capacity
this year, we are in a very good position to meet this high demand.
This expansion of our capacity will make a lasting contribution to
growth as early as 2006." www.catoilag.com

About C.A.T. oil AG: Austria-based C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78) is one of the leading providers of oilfield 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. www.catoilag.com
