Schlumberger Ltd. (NYSE: SLB) detailed $45.27 billion in revenue for full-year 2013 on Jan. 17. The year’s earning is above 2012’s $41.73 billion, the company said. 2013’s full-year income excluded $6.33 billion in charges and credits, the company added. This represents diluted earnings per share for the year at $4.75, up from 2012’s $4.01 per share, the company said.

Additionally, the company detailed 2013’s fourth quarter results. Quarterly revenue was $11.91 billion, above $11.08 billion in 2012 for the same quarter, the company said. Diluted earnings per share for 2013’s fourth quarter were $1.35, the company said.

Company CEO Paal Kibsgaard remarked the year ended “with revenue of more than $45 billion, up 8%” due to “higher exploration and development activity” onshore and offshore.

He added, “In North America, we demonstrated continued resilience to the challenges of the land markets by growing the business by close to $400 million, or 3%, aided by our strong position in the offshore market, particularly in the US Gulf of Mexico.”

Schlumberger repurchased 11.9 million common shares, at an average price of $89.67 per share, for a total purchase price of $1.07 billion during fourth quarter 2013, the company added.
