July 21, 2009 To Whom It May Concern: I have been using WestRock Geo for the last couple of years now and have been very impressed so far. They are very prompt and professional. The skill level that they execute in the field is second to none, and I trust them completely. Being an office geologist I need someone out on the rig to be my eyes and ears, and with WestRock Geo, I feel they are the best at this. They always know what is happening on the rig and call me as soon as possible if something goes wrong. They are also very good at calling me at the same time every morning for an update. I would also like to mention that I get my Strip log and reports in very timely manner, which makes my job a lot easier. I will continue to use Westrock Geo and I would recommend them to anyone. Sincerely, Shane Sutherland, P.Geol Harvest Energy Trust

Mr. Ryan Cuthbertson Chief Operating Officer WestRock Geo Inc. 140, 7260-12th St. SE Calgary, Alberta T2H 2S5 October 2008 We would like to thank you for the outstanding customer service and geological support that has enabled Auburn Energy Inc. to successfully complete its current four-well horizontal project in southeast Saskatchewan. WestRock Geo on-site personnel played a key role in ensuring that we landed and set intermediate casing at the optimum coordinates, started our horizontal legs in-zone, and stayed in-zone through to total depth on each well. Working along side WestRock Geo has been a great experience for us, and we would highly recommend WestRock Geo to industry associates for their drilling projects. I would be very pleased to provide feedback directly to any potential clients you wish to have contact me, either by phone at the number below, or by email to jstyles@auburnenergy.ca.
