Key words<\/strong>: managed pressure drilling, deepwater drilling, offshore drilling, dual gradient drilling, riser, offshore exploration.

The article is about problem of drilling deepwater oil and gas wells that consists in complicating and increasing cost of their well design due to narrowing mud window at different depths. The authors analyze drilling technology developed and applied in practice of offshore drilling with a dual gradient drilling, which allows drilling significant intervals without overlapping an intermediate casing string. Based on analysis of these technologies and taking into account their disadvantages the authors proposed a new drilling technology of dual gradient drilling with placement of all necessary innovative equipment on drilling platform.<\/p>\n
