On 26 September 2008, KNOC signed a deal with the Kurdistan Regional Government where KNOC was granted rights to explore and drill on several sites in the Iraqi Kurdistan in exchange for valuable support on a range of infrastructure projects.

In 2009, the company purchased Harvest Operations for US$1.7 billion, along with its subsidiary North Atlantic Refining and its refinery in Come By Chance, Newfoundland and Labrador. It also assumed Harvest's US$2.2 billion in outstanding debt. The US$3.9 billion bid was one of KNOC's largest deals at the time.

On 2 July 2010, KNOC confirmed preliminary discussions regarding a US$2.9 billion offer for the entire issued and to-be-issued share capital of Aberdeen-based Dana Petroleum. In September 2010, Dana's management had continued to reject the takeover approach, but 64% of shares had already been bought by KNOC. The takeover was official in October 2010, when KNOC secured 90% of Dana Petroleum's shares by going straight to the shareholders. The action led to the resignment of the chairman and three non-executive directors from the board.
