--- title: "Schlumberger: Competitors" description: "Schlumberger compared with companies that share its SEC industry classification: revenue, growth and margins from SEC filings, and how the peer group is chosen." canonical: https://www.getswoopr.com/stocks/companies/schlumberger/competitors/ source: "Swoopr Investment: https://www.getswoopr.com" --- # Schlumberger: Competitors & Industry Structure ## Direct Answer SEC EDGAR classifies Schlumberger under SIC code 1389 (Oil & Gas Field Services, NEC). Among Swoopr's S&P 500 Equal Weight companies, 9 others share that classification; by latest reported revenue, Schlumberger ranks 1 of 10. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes. ## How Does Schlumberger Compare With Its Peers? | Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin | | --- | --- | --- | --- | --- | | **Schlumberger (SLB)** | $35.7 billion FY2025 | -1.6% | n/a | 9.4% | | [Halliburton (HAL)](https://www.getswoopr.com/stocks/companies/halliburton/) | $22.2 billion FY2025 | -3.3% | 10.2% | 5.8% | | [ProFrac Holding Corp.

(TUSK)](https://www.getswoopr.com/stocks/companies/mammoth-energy-services-inc/) | $44 million FY2025 | -2.9% | -129.7% | 10.4% | Revenue growth compares each company's latest fiscal year with the one before. Fiscal years do not always end on the same date, so treat close comparisons with care. ## How Does Schlumberger Rank Among All SEC Filers in Its Industry Code? 10 companies with annual reports in Swoopr's SEC dataset share SIC code 1389 (Oil & Gas Field Services, NEC), a wider group than the S&P 500 Equal Weight companies above. Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars. | Measure | Schlumberger | Median of filers | Rank | | --- | --- | --- | --- | | Revenue | $35.7 billion | $1.3 billion | 1 of 10 | | Revenue growth | -1.6% | -3.2% | 3 of 10 | | Net margin | 9.4% | 3.1% | 3 of 10 | A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality. ## Where These Numbers Come From Every figure on this page is a value Schlumberger reported in its own SEC filings, read from the SEC's XBRL data (accession 0001193125-26-021017 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary. Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation. ## Frequently Asked Questions ### Who are Schlumberger's competitors?

By the SEC Standard Industrial Classification code each company files under, within Swoopr's S&P 500 Equal Weight company set, falling back to the two-digit major group when fewer than two companies share the exact code. Classification codes are broad, so read the peer list as a screen, not a verdict. ### How does Schlumberger rank among all companies in its SEC industry?
