addition, significant progress was also made in improving the results of previously underperforming business units and digital technology adoption has increased. Overall this quarter, we posted a decremental operating margin of 18% sequentially.
“In response to market conditions, we recorded $3.7 billion of pretax restructuring and asset impairment charges, including $1 billion of severance costs, as of the end of the quarter. The remaining portion of the charge largely relates to the non-cash impairment of certain assets.
“Altogether, I am extremely proud of our operational and financial performance during the quarter as we continue to build the foundation for our future success while we navigate the trough of this downcycle.
“Looking at the macro view in the near-term, oil demand is slowly starting to normalize and is expected to improve as government measures support consumption. However, subsequent waves of potential COVID-19 resurgence pose a negative risk to this outlook.
“The conditions are set in the third quarter for a modest frac completion activity increase in North America, though from a very low base. Internationally, markets may continue to be disrupted by the pandemic and will continue to adjust to budget levels set during the second quarter, but this would be mostly offset by the seasonal return of activity in the Northern Hemisphere and the rebound of Latin America from its second-quarter weakness. However, any further material COVID-19 disruption or significant setback in oil demand arising from a slower economic recovery could present downside risks to this outlook. Absent these risks, we anticipate flat sequential revenue on a global basis and our pretax segment operating income and margin should expand as a result of our restructuring efforts, improved activity mix, and sustained benefits from technology adoption, including digital.
“We believe the decisive and comprehensive measures we have taken to face the industry reality will continue to protect our liquidity and cash positions and allow us to expand our margins. We have taken the long-term view in restructuring our company—aligning with our customers’ workflows, empowering a lean and responsive organization, and accelerating the execution of our performance strategy, with capital stewardship, fit-for-basin, and digital as key attributes of success. I am extremely optimistic about the future of Schlumberger, building on the strength of our international franchise and positioning the company as the performance partner of choice for our customers in the new industry landscape.”
