(Reuters) - Precision Drilling Corp (PD.TO), Canada's largest oil and gas driller, posted a fourth-quarter profit as increased drilling activity in North America boosted dayrates.
October-December net income was C$28 million ($28.13 million), or 10 Canadian cents per share, compared with a loss of C$250,000, a year ago.
The company said a charge associated with asset decommissioning hurt earnings by C$76 million.
Revenue rose 35 percent to C$587 million.
"United States drilling activity continued to increase in 2011 driven by oil and liquids-rich activity," the company said in a statement.
