Full-year 2014 revenue of $48.6 billion grew $3.3 billion, or 7%, versus the same period last year with International revenue of $32.1 billion increasing $1.2 billion, or 4%, and North America revenue of $16.2 billion growing $2.3 billion, or 16%.
Internationally, higher activities in a number of GeoMarkets, both offshore and in key land markets, contributed to the increase.
The increase was led by the Middle East & Asia which increased 10%, mainly from robust drilling and exploration results in Saudi Arabia, Australia, the United Arab Emirates and Oman.
Europe/CIS/Africa increased 1%, led by the SubSaharan Africa region on strong development and exploration activities, particularly in Central West Africa, Angola and Continental Europe GeoMarkets.
Norway also experienced strong growth driven by market share gains and higher rigrelated services for a number of customers.
Latin America, however, decreased 1% primarily as a result of lower activity and pricing in Brazil and Mexico which was partially offset by strong activity in Argentina and Ecuador.
North America revenue increased 16% mainly due to land which was up 22%, while offshore was down 3%.
The increase in land was driven by market share gains in pressure pumping, artificial lift and drilling services.
The pressure pumping growth was augmented by improvements in operational efficiency and the introduction of new technologies.
The decrease in offshore revenue was attributable to lower drilling and exploration activities, and due to a series of operational delays that impacted several product lines earlier in the year combined with lower multiclient sales.
Full-year 2014 pretax operating income of $10.6 billion grew $1.2 billion, or 13%, versus the same period last year with International pretax operating income of $7.7 billion increasing 12% and North America pretax operating income of $3.1 billion increasing 12%.

The increase in International Area margins reflected increased high-margin exploration activities, market share gains, growth in accretive integration-related activities and premium pricing on new technology introductions.
The North America margin contraction reflected pressure pumping commodity inflation.
