Schlumberger Business Consulting (SBC) was founded in 2004 as the management consulting arm of Schlumberger, the world’s largest oilfield services company. The initiative was spearheaded by Schlumberger’s leadership – notably backed by then-CEO Andrew Gould – and led by Antoine Rostand, a former A.T. Kearney partner who returned to Schlumberger to launch the new consulting venture. The company was acquired by Accenture in 2015.
From its inception, SBC focused on providing advisory services to the oil and gas industry, leveraging Schlumberger’s deep technical heritage in exploration and production (E&P). Throughout the late 2000s, SBC expanded rapidly: by 2009 it had begun building a global senior leadership team and opening offices in key energy hubs (e.g. Houston, Paris, London) to support a growing international client base.
A notable milestone in its growth came in 2011, when SBC established the SBC Energy Institute, a non-profit think tank in The Hague. This institute, launched with the involvement of prominent energy figures (such as former IEA head Claude Mandil and ex-OPEC Secretary General Adnan Shihab-Eldin), aimed to research energy technologies and inform strategic decisions on the future energy mix. The institute published a biannual “Energy FactBook” that became a reference for industry analysts by compiling data and insights on both fossil fuels and emerging renewables.
By the mid-2010s, SBC had firmly established itself as a leading specialist consultancy in the energy sector, known for marrying management consulting expertise with a deep understanding of oilfield operations and technology. This reputation set the stage for its acquisition by Accenture in 2015.
Consulting Services and Industry Focus
SBC offered a broad range of management consulting and advisory services tailored specifically to energy companies. Its primary service lines included:
- Strategy consulting – Helping clients set corporate and business unit strategies, portfolio plans, and market entry or growth strategies.
- Operations consulting – Optimizing operational performance in exploration, drilling, production, and supply chain processes.
- People & transformation – Organizational and human capital advice, including talent management, leadership development, and change management programs.
- Capital projects – Advising on planning and execution of large capital investments (such as megaprojects in upstream development), improving project management and delivery.
- Mergers & Acquisitions – Supporting transactions and post-merger integrations within the energy sector, leveraging industry insights for due diligence and synergy realization.
While SBC’s offerings covered general business consulting areas, they were all delivered with a strong energy industry focus. The firm’s client base and expertise centered on the oil and gas industry, especially the upstream segment (exploration and production). SBC became “a leading provider of consulting services to the upstream oil and gas industry,” advising major international oil companies, national oil companies, and oilfield service providers on a wide range of strategic and operational issues. It also served the broader energy sector beyond upstream oil & gas – one industry publication noted SBC was a global consulting player in energy and utilities, though its work in power/utilities often intersected with its oil & gas knowledge areas. In practice, SBC’s projects ranged from redesigning the operating model of oil companies, to improving drilling performance, to guiding energy firms through organizational change.
Specific notable projects are typically confidential, but SBC was known for its thought leadership initiatives that shed light on industry challenges. For example, starting in 2004 SBC conducted an annual Oil & Gas HR Benchmark Survey to track workforce trends in the E&P sector. By 2011 (the survey’s eighth year), 37 upstream companies – accounting for ~37% of global oil and gas production – were participating. These surveys highlighted critical issues such as the “looming talent shortage” in petroleum engineering and geoscience as the generation of specialists hired before the 1980s approached retirement. SBC coined this demographic challenge the “great crew change,” and repeatedly warned industry leaders to address the gap in experience and skills. This focus on human capital underscored SBC’s people & transformation consulting capabilities in action. Additionally, through the SBC Energy Institute, the firm produced the Energy FactBook and other research on topics like renewable energy, energy storage, and efficiency – extending its advisory influence into emerging energy domains. By combining such industry-specific research with on-the-ground consulting, SBC positioned itself as an expert adviser capable of tackling the unique strategic, technical, and organizational challenges of energy companies.
Pre-Acquisition Scale and Global Presence
By the time of its acquisition in 2015, SBC had achieved a respectable scale as a niche consulting unit. The firm had over 250 consultants in its ranks, operating from nine offices worldwide. These offices were strategically located in major energy hubs across all regions. In particular, SBC’s global network included locations such as Abu Dhabi, Houston, Paris, London, Kuala Lumpur, Mexico City, Moscow, Rio de Janeiro, and Singapore. This geographic spread enabled SBC to support clients on-site in important markets and to undertake projects spanning the Americas, EMEA, and Asia-Pacific. Notably, SBC was structured more by global practice areas and regions rather than by individual countries – consultants often worked internationally, bringing expertise wherever needed.
In terms of financial performance, public data on SBC was limited (Schlumberger did not break out SBC’s results in its filings). However, estimates at the time of acquisition pegged SBC’s annual revenue at roughly €100 million (approximately $110 million). This figure suggests that SBC, while profitable, was a relatively small piece of Schlumberger’s overall business (for context, Schlumberger’s total revenues were $48.6 billion in 2014) and also a tiny fraction of Accenture’s ~$31 billion in revenue that year. One analysis noted that adding SBC’s revenue would contribute “less than a quarter of 1%” to Accenture’s annual sales. Nonetheless, the value of SBC to Accenture lay not in its sheer size but in its specialized talent and client relationships. At around 250 consultants, SBC was boutique-sized compared to generalist consulting giants, but it was highly regarded within its domain – essentially punching above its weight by advising many of the oil & gas industry’s leading companies. This combination of a global footprint and deep industry focus made SBC an attractive acquisition target when industry conditions evolved in the mid-2010s.
Accenture’s 2015 Acquisition: Strategic Rationale and Immediate Impact
In August 2015, Accenture announced an agreement to acquire Schlumberger Business Consulting, and the deal was completed by November 2015. The terms of the transaction were not disclosed, but the strategic intent was clearly articulated. Accenture – one of the world’s largest consulting and technology services firms – sought to expand its strategy consulting capabilities in the upstream oil and gas sector by bringing in SBC’s expertise. The timing coincided with a challenging period in the oil industry: crude prices had fallen sharply in late 2014 and remained low through 2015, forcing energy companies to cut costs and rethink their strategies. This context made SBC’s skill set particularly valuable. As Accenture’s Group Chief Executive for Strategy, Mark Knickrehm, explained, the acquisition would “further strengthen Accenture Strategy’s ability to provide key strategic insights to clients in the upstream oil and gas industry” by combining Accenture’s technology-driven business strategies with SBC’s core strengths in oil & gas consulting. In other words, Accenture recognized that oil companies not only needed cost reduction and efficiency measures during the downturn, but also guidance on navigating industry disruption – from volatile prices to new regulations and digital technology shifts. Jean-Marc Ollagnier, chief executive of Accenture’s Resources operating group (which includes energy), noted that the upstream sector was undergoing a “fundamental transformation” and that the acquisition would enhance Accenture’s ability to help energy clients address challenges like capital project delivery, production cost reduction, and even expansion into renewables. By acquiring SBC, Accenture aimed to offer a combination of business, digital and technology know-how that would differentiate its services in the oil and gas market.
From Schlumberger’s perspective, divesting SBC fit its strategic and financial agenda during the downturn. Schlumberger was consolidating operations and cutting costs (the company announced layoffs of about 9,000 employees in early 2015 amid the oil price collapse) and was focusing on its core oilfield services and technology business. Selling the consulting arm provided Schlumberger with some compensation for a non-core asset and allowed it to “minimize the pain from the oil industry slowdown” by offloading a business that, while successful, was outside Schlumberger’s main line of services. Industry observers noted that Schlumberger had managed SBC as an independent unit, which likely made the sale and separation easier. The deal was ultimately seen as a win-win: Schlumberger could double-down on its primary business, and Accenture could acquire top-notch talent and client relationships in a sector where it sought to grow.
In terms of immediate impact, the acquisition was structured as a talent and capability grab. All approximately 250 SBC consultants and staff were expected to join Accenture as the business transitioned over. Upon closing, Accenture integrated these professionals into its organization (with no layoffs announced, as retention of expertise was a key goal). Accenture did not acquire any rights to the Schlumberger brand name – an important detail for branding – so the “Schlumberger Business Consulting” name and trademarks were not transferred and would not be used post-closing. In essence, SBC ceased to exist as a separate brand after November 2015. The swiftness of the integration (the deal closed within a few months) and the fact that terms weren’t publicly disclosed suggests it was a relatively straightforward absorption, likely focused on blending SBC’s consulting practice into Accenture with minimal disruption to ongoing client projects. Accenture quickly emphasized to clients that the acquisition “expands Accenture Strategy capabilities in upstream oil and gas”, indicating that SBC’s team would be immediately leveraged to enhance Accenture’s consulting offerings for energy companies.
Integration into Accenture Strategy and Energy Industry Group
After the acquisition, SBC’s people and expertise were folded into Accenture Strategy, which is Accenture’s division for high-level consulting and strategy advisory services. The entire SBC workforce and its knowledge assets became part of Accenture Strategy’s global team. In practical terms, this meant that Accenture established a stronger dedicated group focusing on energy (especially oil & gas) strategy consulting within its Strategy unit. Arthur Hanna, Accenture Strategy’s Energy industry lead, stated that Accenture’s existing capabilities in business, digital, and technology strategy “complement the upstream business, organizational change and operations expertise” that came with SBC. This highlights how integration was approached: by combining Accenture’s strengths (such as digital strategy and technology implementation) with SBC’s strengths (deep upstream industry insight and management consulting), the integrated team could offer a more holistic service to energy clients. The former SBC consultants essentially became Accenture’s Upstream Oil & Gas consulting practice inside the company. They teamed up with Accenture’s pre-existing Energy industry group (part of the Resources operating group) to align strategy recommendations with broader industry solutions. Jean-Marc Ollagnier of Accenture’s Resources group noted that the move would “elevate the firm’s ability to assist companies [to] improve portfolio optimization, enhance operational agility and cost competitiveness, as well as plan and execute digital-driven transformations.” By acquiring SBC, Accenture saw the integrated capability as spanning from boardroom strategy to technology-enabled execution, all within the energy domain.
The integration process involved absorbing SBC’s consulting methodologies, client relationships, and sector research into Accenture’s frameworks. SBC’s proprietary tools or intellectual capital (for instance, benchmarks and databases from its annual surveys or the Energy Institute research) became part of Accenture’s knowledge base. Culturally, Accenture kept the team intact but now under Accenture leadership: the SBC consultants started reporting through Accenture’s management hierarchy and working under the Accenture brand. Accenture also likely cross-trained teams so that the former SBC specialists could partner with Accenture’s technology consultants on multi-disciplinary projects. One immediate effect was that Accenture Strategy’s Energy practice grew in headcount and expertise overnight, gaining seasoned advisors in upstream strategy, operations, and organizational improvement. Mark Knickrehm (Accenture Strategy’s chief) highlighted that the SBC professionals’ core consulting strengths in oil & gas would be perfectly complemented by Accenture’s broader portfolio of services (strategy, consulting, digital, technology) to provide unique value to E&P clients. Indeed, the combination allowed Accenture to present a “one-stop” value proposition: the strategic insight of a boutique energy specialist, backed by the implementation muscle and digital tools of a global consulting firm. This integration was timely as oil companies in 2015-2016 were not only reeling from low prices but also exploring digital innovations (like analytics, IoT, automation) to drive efficiency – areas where Accenture could now offer joint expertise.
Within Accenture, the former SBC team became an integral part of the Accenture Energy Industry Group (which covers oil & gas, among other energy segments) and worked closely with other Accenture Strategy consultants. They also contributed to Accenture’s thought leadership in energy. (For example, after joining Accenture, the ex-SBC experts continued to publish insights on topics such as upstream workforce dynamics, capital project optimization, and digital oilfield strategies, but now those appeared under Accenture’s brand). The SBC Energy Institute’s activities were likely continued in some form through Accenture’s research programs, ensuring that the thought leadership roles of SBC’s senior advisors carried on. In summary, integration was achieved by embedding SBC’s niche capabilities into Accenture’s global service lines – effectively, SBC became the upstream oil & gas center of excellence within Accenture Strategy. All client engagements that SBC would have handled independently were now delivered as “Accenture Strategy” projects (often with the same teams, just a different business card), and clients gained access to Accenture’s additional experts in technology, analytics, and consulting. This seamless integration enabled Accenture to immediately present a stronger front in the market: by late 2015 Accenture could claim it offers “end-to-end” services for oil and gas companies, from strategy through to execution, underpinned by the fresh infusion of SBC’s industry know-how.
SBC’s Positioning vs. Accenture’s Capabilities (Pre- and Post-Acquisition)
Pre-acquisition, SBC’s positioning was that of a highly specialized, boutique management consultancy focused on the energy sector. In just over a decade, SBC had built a reputation as “a leading management consulting provider in the upstream oil and gas industry, and a leading player in the energy sector more generally.” Unlike diversified consulting firms that serve many industries, SBC concentrated almost exclusively on oil, gas, and energy-related projects. This gave it a distinct competitive edge in that domain. Clients valued SBC for its deep domain expertise – its consultants often had engineering or operational backgrounds in oil & gas (many came from Schlumberger or the industry) combined with top-tier consulting skills. SBC’s close ties to Schlumberger also meant it had an insider understanding of oilfield technology and challenges. Jean-Marie Rousset, SBC’s Senior Vice President, described the firm’s unique strength as the combination of “management consulting expertise [with] a deep understanding of exploration and production (E&P) technologies and industry challenges.” This niche positioning allowed SBC to punch above its weight when competing with larger generalist firms. For example, SBC could credibly advise an oil major on how to optimize drilling operations or an LNG project’s organization by bringing in not just generic best practices, but very tailored, technical insights that only an oil & gas specialist would know. However, as a smaller entity, SBC was somewhat limited in breadth of services – it focused on strategy and management consulting and did not offer IT implementation, large-scale outsourcing, or other services that the Big Four or big tech-consulting firms might offer. In summary, before being acquired, SBC was seen as an elite boutique consultancy in energy: highly respected in its field, but with a narrow industry scope and modest scale.
Accenture’s capabilities pre-acquisition, by contrast, were broad and robust across industries, including oil and gas, but Accenture’s strengths in energy tended to lie in technology, IT systems, and operational consulting rather than pure strategy. Accenture had a sizable Energy practice within its Resources group, serving oil and gas clients with solutions in digital oilfield systems, enterprise IT, supply chain, and more. Prior to 2015, Accenture was certainly advising oil companies, but often in contexts like implementing ERP systems, improving asset maintenance processes, or outsourcing support functions – areas where it had a strong track record as a technology and outsourcing partner. Accenture had only formed Accenture Strategy in 2014 as a distinct entity to boost its high-end strategy consulting presence. Thus, when it came to board-level strategic advisory in oil & gas, firms like McKinsey, BCG, Bain, or specialized boutiques (including SBC) were more prominent. The acquisition of SBC immediately helped close that gap for Accenture. Industry analysts noted that the deal would “move Accenture into the paths of strategy-focused firms and energy specialist firms” by giving it the seasoned upstream strategists it previously lacked. In essence, post-acquisition Accenture could offer the same caliber of strategic counsel in energy as a pure-play firm like SBC, but packaged with Accenture’s extensive implementation capabilities. Accenture’s value proposition to energy clients became more comprehensive: it could engage at the strategy formulation stage (for example, helping an oil company decide how to rebalance its portfolio or enter a new market), and then continue through design and execution (for example, implementing digital solutions, reorganizing the workforce, overhauling supply chain systems) – a continuum that few competitors could match as seamlessly.
A side-by-side comparison: SBC pre-merger vs. Accenture post-merger – highlights a shift from specialization to scale and integration. SBC brought specialization in upstream oil & gas consulting, intimate industry knowledge, and a high-touch boutique consulting approach. Accenture post-merger combined that specialization with vast resources, global delivery teams, and cross-industry experience. Accenture also brought exposure to other areas of energy (such as utilities, renewables, downstream) where SBC’s work had been limited; thus the former SBC team could now apply their skills in a broader context with support from colleagues in those sectors. In terms of offerings, where SBC might have previously advised a client to pursue a certain operational improvement, Accenture could now not only advise but also implement the supporting technology or even run outsourced operations if needed – giving clients an end-to-end solution. From a market positioning standpoint, after integrating SBC, Accenture could credibly market itself as a top-tier strategy and consulting provider to the energy industry (in addition to its pre-existing identity as a tech/services provider). Accenture effectively acquired a reputation along with SBC: as one energy publication put it, “Accenture… will extend its reach to the [energy] industry through the acquisition of SBC”, leveraging “its established strength in IT and technologies coupled with SBC’s strategy and management consulting expertise.” This combination of capabilities was particularly powerful during the industry downturn – energy firms needed both strategic direction and practical solutions to cut costs and innovate, and the Accenture+SBC team was well suited to deliver both.
It’s also worth noting that scale and global reach changed post-acquisition. SBC’s ~250 consultants joined an Accenture workforce of over 336,000 employees worldwide. Post-merger, those consultants had access to Accenture’s massive infrastructure and client network. For existing SBC clients, this meant the same trusted advisors were now backed by a much larger organization that could offer additional services. For Accenture’s existing clients, it meant new high-level advisory offerings were available in-house. The net effect was a strengthening of Accenture’s positioning: after 2015, Accenture could claim unparalleled breadth in energy consulting – from strategy (thanks to SBC) to digital, from operations improvement to outsourcing – whereas SBC on its own could claim depth but not that breadth. In summary, SBC pre-acquisition was a focused, high-impact boutique with unmatched oil & gas expertise, and Accenture post-acquisition became a one-stop shop for energy consulting, integrating SBC’s niche strengths into its global consulting powerhouse.
Post-Integration Leadership and Strategic Changes
Following the integration into Accenture, there were several leadership and organizational changes that marked the new chapter for SBC’s legacy and its people. First, the branding and identity of SBC were fully absorbed – as noted, the SBC name was retired and all consultants began operating under the Accenture Strategy banner. This meant that by 2016, the market no longer saw “Schlumberger Business Consulting” as an independent entity; its website was likely taken down and any ongoing engagements were rebranded to Accenture.
In terms of leadership, Accenture retained many of SBC’s senior consultants, but the top executive roles shifted as the group blended into Accenture’s structure. Notably, Antoine Rostand – the founder and president of SBC – stayed through the transition period in 2015 but departed the company after integration was completed. In March 2016, it was reported that Rostand joined A.T. Kearney as a Senior Advisor in its global energy practice. His decision to leave was not unexpected: as the founder, he had entrepreneurial roots and had previously been a partner at A.T. Kearney, so he opted to pursue a new venture once SBC was successfully integrated into Accenture. Rostand’s exit symbolized the end of SBC as a standalone venture, but he left behind a strong team now embedded in Accenture.
Many other SBC leaders and consultants took on roles within Accenture. For example, Jean-Marie Rousset, who had been a Senior Vice President at SBC and one of its key leaders, continued with Accenture and became a Managing Director in Accenture Strategy, focused on energy projects. Rousset brought over 12 years of SBC experience and remained based in Houston, advising oil and gas clients under the Accenture umbrella. Similarly, other SBC principals likely assumed Accenture Strategy titles (often equivalent to Accenture partners or directors) and were tasked with leading client engagements and developing business in the energy sector. Accenture, known for its matrix organization, would have slotted these individuals into its industry practice and service line leadership as appropriate. In some cases, Accenture may have appointed former SBC executives to lead new combined teams or offerings. For instance, if SBC had a head of upstream operations consulting, that person might become the lead for upstream strategy within Accenture’s Energy practice. The acquisition announcement included quotes from Accenture’s leadership and from SBC’s Jean-Marie Rousset, indicating a collaborative leadership approach during integration.
Operationally, the consulting methodologies and tools of SBC were integrated into Accenture’s frameworks. Any ongoing multi-year projects that SBC had were transitioned to Accenture management smoothly, with clients seeing continuity in personnel. Over time, former SBC consultants began working not only on their legacy client accounts but also on new projects for Accenture’s broader client portfolio, including possibly cross-industry engagements (bringing their expertise to, say, a utility or a mining company, in addition to oil & gas clients). The service offerings that SBC had – strategy, operations, transformation, etc. – were rolled into Accenture Strategy’s service catalog for Resources industries. Accenture also likely leveraged SBC’s thought leadership; for example, the Oil & Gas HR Benchmark Survey could have continued under Accenture’s name or its findings incorporated into Accenture’s research publications. The SBC Energy Institute’s research might have been utilized by Accenture to bolster its credentials in energy policy and technology discussions.
Strategically, Accenture’s approach to the energy sector evolved to reflect the influence of SBC’s expertise. With the market still in a downturn through 2016-2017, the combined team prioritized offerings that addressed oil and gas companies’ urgent needs: restructuring, cost optimization, and digital transformation. Accenture Strategy (with SBC integrated) started advising clients on how to restructure their portfolios and organizations to survive prolonged low oil prices, something SBC had experience with, now augmented by Accenture’s capabilities in data and digital. One observable change was that Accenture became more visible and active in high-level energy consulting forums – for instance, Accenture Strategy’s energy leads (including ex-SBC personnel) spoke at industry conferences and contributed to articles on the future of oil & gas, a role that SBC leaders used to play independently. Accenture also ramped up its thought leadership, issuing reports on topics like “energy transition” and “digital in oil & gas,” areas where the former SBC team’s insights were invaluable. In 2018, Accenture Strategy’s Energy team (with ex-SBC members like Jean-Marie Rousset) was present at events such as the World Energy Capital Assembly, indicating their continued thought leadership role in the industry under the Accenture name.
