HAL vs SLB: how the two businesses compare
Halliburton (HAL) and Schlumberger (SLB) do not both have comparable annual revenue in the SEC XBRL snapshot, so this comparison rests on business descriptions, classifications, and filings. Both file with the SEC under the same industry code, SIC 1389 (Oil & Gas Field Services, NEC).
Figures come from each company's own SEC filings. This page compares the businesses; it is not a price target or a verdict.

Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end December 31, so annual reports line up, but check segment definitions before comparing growth or margins.
The current verified House and Senate snapshot contains 14 matched transaction rows for HAL and 15 matched transaction rows for SLB. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
