Ensign Energy Services Inc. Announces Renewal of Normal Course Issuer Bid

/NOT FOR DISTRIBUTION TO US NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/

CALGARY, June 3, 2011 /CNW/ - Ensign Energy Services Inc. ("Ensign" or the "Company") (TSX:ESI) announces today that the Toronto Stock Exchange ("TSX") has accepted Ensign's Notice of Intention to commence a Normal Course Issuer Bid (the "Bid") to purchase, from time to time, as it considers advisable, up to 7,660,512 common shares (which is equal to 5% of the outstanding common shares) on the open market through the facilities of the TSX or other Canadian alternative markets, if eligible. The number of common shares that can be purchased pursuant to the Bid is subject to a daily maximum of 80,072 common shares (which is equal to 25% of the average daily trading volume for the six months ended May 31, 2011). The average daily trading volume for the six months ended May 31, 2011 was 320,288 common shares, excluding common shares purchased in the last six months pursuant to the Current Bid (as defined below). The price that Ensign will pay for any common share under the Bid will be the prevailing market price on the TSX at the time of such purchase or, with respect to purchases made on the alternative markets, such price as is required under applicable securities legislation. Common shares acquired under the Bid will be subsequently cancelled. Ensign currently has 153,210,232 common shares outstanding.

The Bid will commence on June 7, 2011 and will terminate on June 6, 2012 or such earlier time as the Bid is completed or terminated at the option of Ensign. A copy of the Form 12 - Notice of Intention to make a Normal Course Issuer Bid filed by the Company with the TSX can be obtained from the Company upon request without charge.

The Bid is a renewal of the normal course issuer bid (the "Recent Bid") commenced by the Company on June 1, 2010, which expired on May 31, 2011. Under the Recent Bid the Company purchased for cancellation 200,000 Common Shares, at a weighted average price of $11.6434 per Common Share.

The Company is commencing the Bid because it believes that, from time to time, the market price of its Common Shares may not properly reflect the underlying, intrinsic value of Ensign, and that, at such times, the purchase of Common Shares for cancellation will increase the proportionate interest of, and be advantageous to, all remaining shareholders.

Ensign is an international oilfield services contractor based in Calgary, Alberta.  Ensign's Common Shares (symbol: ESI) are publicly traded through the facilities of the Toronto Stock Exchange.
