Halliburton Completion and Production revenue in the second quarter of 2020 was $1.7 billion, a decrease of $1.3 billion, or 44%, when compared to the first quarter of 2020, while operating income was $159 million, a decrease of $186 million, or 54%. These declines were driven by a decrease in pressure pumping activity globally, primarily in U.S. land and Latin America, coupled with lower artificial lift activity in U.S. land. This was partially offset by improved completion tool sales internationally.
Drilling and Evaluation revenue in the second quarter of 2020 was $1.5 billion, a decrease of $551 million, or 27%, when compared to the first quarter of 2020, while operating income was $127 million, a decrease of $90 million, or 41%. This decline was primarily due to a global reduction in drilling-related services and lower software sales internationally
