Item 8.01 Other Events

Core Laboratories N.V. ("Core Lab") today announced pricing of the offering by its U.S.-based, wholly owned subsidiary, Core Laboratories LP ("CLLP"), of $250 million aggregate principal amount of senior exchangeable notes due 2011 through an offering within the United States to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). The notes will bear interest at a rate of 0.25% per year. The notes will be fully and unconditionally guaranteed by Core Lab. The sale of the notes to the initial purchasers is expected to close on 6 November, 2006. The notes will be exchangeable into Core Lab's common shares under certain circumstances at an initial conversion rate of 10.5533 per $1,000 principal amount of notes, which is equal to a conversion price of approximately $94.76 per share. The initial conversion price represents a premium of approximately 30% relative to the last reported sale price of Core Lab's common shares on The New York Stock Exchange on 31 October, 2006. Upon exchange, holders will receive cash up to the principal amount, and any excess exchange value will be delivered in Core Lab's common shares.

CLLP also granted the initial purchasers a 13-day option to purchase up to an additional $50 million aggregate principal amount of notes.

In addition, Core Lab entered into separate warrant transactions with the financial institution that entered into the exchangeable note hedge transactions covering approximately 2,638,325 Core Lab common shares. Core Lab intends to use substantially all of the proceeds of the warrant transactions of approximately $48 million to repurchase its common shares. The exchange note hedge and warrant transactions will effectively increase the exchange price of the exchangeable note to approximately $127.56 per share of Core Lab's common shares, representing a 75% premium based on the last reported sale price of $72.89 per share on 31 October, 2006.
