"The strength of our fourth-quarter results reflects building momentum in our International operations and a more favorable outlook for our U.S. Drilling operations. Our Completion & Production Services operations posted an improvement in what would usually be a seasonally weaker quarter," said CEO Tony Petrello in a statement.
Management sees continuing improvement over 2014, commencing with the second quarter ending June.
"We foresee substantial year-over-year quarterly improvement, which should accelerate in the second half," added Petrello. "A major factor in our expectation is the outsized contribution of the 140 rig years of long-term rig contracts we have secured over the last 18 months, 90 of which should be realized through 2015 with only 6.7 reflected in our results to date.
