"We will be ready to inform you about our interest in acquiring 2-3 additional assets in Kazakhstan by the second half of this year," Sergei Bogdanchikov told a news conference in the Kazakh capital.
"The company's projected annual growth rate is about 7% and it demands the increase of the raw material base," Bogdanchikov said.
Rosneft has been participating in various oil and gas projects in Kazakhstan, including the joint exploration of the Kurmangazy deposit on the Caspian Sea shelf with Kazakhstan's KasMunaiGaz.
Bogdanchikov said Rosneft was planning to invest "about $66 million" in the exploration of the Kurmangazy deposit in 2006.
Rosneft announced earlier that it had submitted documents on its Russian stock market IPO to the Federal Service for Financial Markets.
The company sees the IPO as a way to attract investment to further develop its resources, to obtain new licenses, and to bid in tenders that the Ministry of Natural Resources will hold in 2006-08.
