Anton Oilfield Services, which sells oil-drilling equipment to PetroChina, Sinopec Corp and China National Offshore Oil Corp, has begun pre-marketing its up to US$200 million initial public offering in Hong Kong.
After two weeks of pre-marketing, Anton would launch a 10-day investor roadshow and price the shares in the middle of next month, market sources said.
Credit Suisse and JP Morgan are arranging the sale.
Beijing-based Anton is the country's largest privately owned oilfield services company. It is structured as a red chip, a mainland company that is registered offshore.
The company was established by former China National Petroleum Corp executive Luo Lin in 1999.
China National Petroleum is the mainland's largest oil producer and the parent of Hong Kong-listed PetroChina.
