Olivier Le Peuch
Chief Executive Officer at Schlumberger
Thank you, ND. Ladies and gentlemen, thank you for joining us on the call today. In my prepared remarks, I will cover our fourth quarter results and follow with a quick review of our full year 2022 achievements. Then I will share some thoughts on the outlook for the full year. Stephane will then provide more detail on our financial results, and we will open for your questions.
To begin, we sustained growth momentum through the fourth quarter, delivering strong revenue growth and further margin expansion, both sequentially and year-over-year. The quarter was characterized by very strong activity growth in the Middle East and offshore and was augmented by robust year-end sales in Digital. Growth was once again broad-based, and our operational, commercial and earnings performance was outstanding.
We ended the fourth quarter with sequential revenue growth and margin expansion in North America and in all international areas. In the international markets, quarterly revenue topped $6 million for the first time in more than four years. Additionally, our international revenue growth rate has visibly outpaced international rig count growth since the cycle trough in 2020. Service pricing, new technology and digital adoption all continued to trend positively.
Looking broadly over the second half of the year, the pace of growth in North America significantly moderated. At the same time, international accelerated, growing in excess of 20% compared to the first half of the year, almost twice the growth rate of North America. We are clearly witnessing the start of a new phase of -- in the growth cycle, which will increasingly be delivered by resilient international growth. This market dynamic led to a lower-than-usual cash flow performance at year-end. However, we further reduced net debt during the quarter and closed the year below our leverage target. Overall, this fourth quarter results helped us surpass our revised full year revenue guidance, and we closed with EPS, pre-segment [Phonetic] operating income and margins all at the highest levels in seven years.
Switching to the full year. 2022 was pivotal for our industry and for SLB. It marked the second consecutive year of outperformance for the energy sector, providing further evidence of the multi-year up cycle and investment momentum that is underway. I would like to take a few minutes to reflect on what we achieved.
We announced our new brand identity with sustainability embedded in everything we do and opened a new chapter for the company. This, firmly positioned, helped SLB to benefit from the underlying macro trends that will shape the future of the energy: Oil and gas technology innovation, industrial decarbonization, digital transformation and new energy systems. We executed consistently for our customers, achieving our best safety and operation integrated performance on record. We advanced our technology leadership and service quality differentiation, leading to more contract awards, higher technology adoption and increased pricing premium.
In our Core divisions, we expanded pretax operating margins by more than 300 basis points. This was led by well construction, which expanded margins by more than 550 basis points. We also launched new products, service and solutions that increase efficiency and lower operational emissions. You have seen many examples of this in today's press release. Our fit-for-basin, technology access and transition technology portfolio have fueled growth and margin expansion in every division and every geographic area throughout the year. And we continue to strengthen our Core portfolio for growth and position for future resilience and returns with the acquisition of Gyrodata and the announced joint venture with Aker Solutions for Subsea.
In Digital, we had strong growth in exploration data, INNOVATION FACTORI and AI solution sales, and the adoption of our new tech digital platform is accelerating. We ended the year with more than 270 DELFI customers, more than 70% growth in DELFI users, and our SaaS revenue more than doubled. These positive undercurrents, combined with higher APS revenue, contributed to the Digital & Integration division's expanding pretax operating margins by more than 170 basis points.
We continue to build adjacent expansion opportunities for our Digital business, both in operation data space and beyond oil and gas, such as carbon management. And in New Energy, we progress technology development milestones, established new partnership partner in CCUS and made new investments that have created a focused yet comprehensive portfolio that offers promising growth opportunity for the future. Today, this portfolio comprise five business areas: Carbon solutions, hydrogen, geothermal and geo-energy, critical minerals and stationary energy storage. And we are accelerating our R&D efforts to develop technology solutions that address hard-to-abate industrial and power generation emissions. As you see, our three engines of growth are on solid footing and are positioned for market success.
In sustainability, we reduced our own carbon emissions intensity in Scopes 1 and 2. And we continue to be one of the highest-ranked companies in our industry across the four rating agencies. We also made significant advance, launching SLB End-to-End Emission Solution, or SEES, an industry first to help our oil and gas customers address methane and other greenhouse gas emissions. Finally, for our shareholders, we demonstrated our commitment to superior returns. We increased our dividend by 40% in April 2022, followed by a further 43% increase announced today. And we resumed our share buyback program this month. These achievements highlight a remarkable year for SLB. It speaks to how we have successfully leveraged the breadth of our portfolio and our competitive strengths to deliver clear, leading outcomes for our customers and shareholders. We are primed for significant success and look forward to carrying momentum into the year ahead.
I would like to extend my thanks to the entire SLB team for delivering an outstanding year. Moving to the macro. We enter 2023 against a backdrop of market fundamentals that remain compelling for both oil and gas and low carbon energy resource. First, despite concern for potential economic slowdown in certain regions, oil and gas demand growth remains resilient. The IEA forecasts that oil and gas demand will grow by 1.9 million barrels to reach approximately 102 million barrels per day. In parallel, markets will remain tightly supplied with modest production increase offset by the end of SPR release and well productivity declines in certain regions, most notably in North America.
Second, there is a greater sense of urgency around energy security. This is resulting in new investment in capacity expansion and diversity of supply. You will see this reflected in a number of new project sanctions, gas supply agreements signed and the return of offshore exploration, all at the pace unforeseen just 18 months ago.
And third, the secular trends of digital and decarbonization are set to accelerate, driven by significant digital technology advancement in cloud and AI, favorable government policy support in New Energy investments and increased spending on low carbon initiatives by operator globally. Underpinning everything, commodity price remained at supportive levels for durable investment.
In North America, spending growth is expected to be more restrained off an exceptionally strong year in 2022. Capital spending growth is expected to increase in high teens as rig counts potentially approach a plateau. Public companies, particularly the majors, are expected to increase short-cycle spending in key U.S. land basins, and drilling activity remain strong to build up well inventory and support target production increase. In the U.S. Gulf of Mexico, where we have a significant presence, we expect the strong spending uplift to continue.
Turning to international. Markets are poised for strong growth in the Middle East and Latin America geographically and more broadly in offshore and in gas. In the Middle East, we expect record levels of upstream investments, with a ramp-up in various capacity expansion projects designed to deliver more gas production and a combined oil increment of 4 million barrels per day through 2030. Offshore activity will continue to strengthen as tieback and new development projects mobilize and new FID are sanctioned, while Russian activity is expected to contract. Excluding Russia, customers' capital spending internationally is expected to increase in the mid-teens. The combination of long-cycle oil capacity expansion projects, offshore deepwater resurgence and strong gas development activity will be a key driver for the multiyear duration of this cycle. This outlook is very favorable for SLB with multiple paths for resilient growth in Core, Digital and New Energy.
On a full year basis, our ambition is to grow revenue in excess of 15% compared to 2022, supported by the step-up in international and offshore momentum, which will augment growth established in North America. As a result, year-on-year adjusted EBITDA growth will be in the mid-20s, driven by further margin expansion. More specifically, in the international markets, we foresee growth in the high teens, excluding Russia, which is set to decline this year. We expect the highest growth rates to be realized in the Middle East and in offshore markets, particularly in Latin America and in Africa. North America, we anticipate about 20% growth supported by offshore strength, land drilling activity and higher pricing. Full year margin expansion will be driven by further positive pricing dynamics, increased technology adoption and improvements from our enhanced operating leverage, mainly internationally.
Let me share with you how we see this year unfolding. Directionally, during the first quarter, we anticipate a typical pattern of activity, beginning with the combined effect of seasonality and the absence of year-end product and digital sales. Additionally, the first quarter will reflect some impact of year-on-year Russia activity decline. This will be followed by a rebound in the second quarter and further acceleration of growth trajectory in the second half of the year, particularly in the international markets. This typical pattern of activity and the favorable dynamics I described earlier combine to support the ambition we have set for full year growth and margin expansion. In addition, the beneficial impacts of an earlier-than-expected reopening in China, the easing of inflationary trends and any further restriction on Russia exports could lead to an acceleration of short cycle activity globally and fast tracking of FID internationally. This could present further upside over the second half of the year.
I will now turn the call over to Stephane.
