Aug 3 (Reuters) - Abu Dhabi National Energy Company is nearing a deal to sell some light oil and natural gas-producing assets in Alberta and British Columbia to privately owned Blue Sky Resources Ltd, three sources familiar with the matter told Reuters. Abu Dhabi National Energy Company, also called TAQA, has reached an agreement on terms of the sale to Blue Sky and the deal is now awaiting approval from the Alberta Energy Board, one of the sources said. Reuters could not immediately learn the deal value and other terms. The sources declined to be identified as the information is not public. They cautioned the Alberta regulator could reject the deal. “If and when any deal is finalized and approved by the relevant authorities, we will make an announcement in line with regulatory requirements,” TAQA told Reuters in an emailed response. Blue Sky did not respond to a request for comment.
