HOUSTON, April 30, 2012 /PRNewswire/ - Tesco Corporation and Schlumberger today announced that they have signed a definitive agreement for Schlumberger to acquire Tesco's CASING DRILLING™ division for $45 million in cash.

"The sale of CASING DRILLING™ will allow Tesco to focus on delivering best-in-class service quality and return on capital employed; a key part of our go forward strategy," said Julio M. Quintana, Chief Executive Officer and President of Tesco Corporation. "Tesco has been an innovator throughout our history and our innovative culture continues to foster new ideas that will add long-term value to our shareholders.  CASING DRILLING™ has been one of our key technologies developed over the years. The time is right to expand the market for this technology through this sale to Schlumberger. With the momentum provided by this transaction and the strength and profitability of our remaining product lines, we are very excited about our future opportunities."

Jean-Francois Poupeau, president, Schlumberger Drilling Group, added, "CASING DRILLING™ technology enables construction of wells where the use of conventional technology has proven difficult. The addition of these technologies to our drilling portfolio will help our customers reduce finding and development costs through drilling efficiency gains and wellbore integrity improvements."
