Oct 5 (Reuters) - North American drilling contractor Precision Drilling Corp PD.TO on Friday said it would buy Trinidad Drilling Ltd TDG.TO in a deal valued at C$1.03 billion ($796 million), trumping a hostile bid from rival Ensign Energy Services ESI.TO .
The acquisition, which has an enterprise value of about C$4 billion, makes Precision the third-largest driller in the United States with more than 200 active rigs and 322 rigs in total, said the companies, both based in the Canadian province of Alberta.
"We'll have strong coverage in other U.S. shale plays and in the Permian," said Precision Chief Financial Officer Carey Ford on a call with analysts.
Precision expects the deal, which was unanimously approved by Trinidad's board, to save it more than C$30 million per year.
Trinidad's board in August rejected a C$1.68 per share all-cash bid from Ensign and instead urged shareholders to accept an all-stock offer from Precision. The all-stock bid, C$1.98 per share based on the bidder's closing price on Thursday, represented a 7.6 percent premium to Trinidad's closing price on that day.
Oil producers in Alberta face pipeline bottlenecks that result in very big price discounts for Western Canada Select heavy crude SHRWCSMc2 to U.S. benchmark crude CLc1 .
Those differentials have left Canadian oil-producing companies trailing their U.S. peers and kept them cautious about spending. Trinidad has lost money since 2015.
" It's positive to see continued consolidation in the land rig space," analysts at Capital One Securities Inc wrote in a note on Friday.
The deal comes a few months after Independence Contract Drilling and Sidewinder Drilling merged their businesses, and Weatherford International WFT.N sold a portion of its land rigs in the Middle East to ADES International. debt, the deal is valued at C$551 million and is expected to close in late-2018.
Shares of Trinidad were up 6 percent at C$1.95 on the Toronto Stock Exchange, while Precision's shares were down about 1.6 percent and Ensign's were off nearly 7 percent in afternoon trading on Friday.
Ensign declined to comment.
