As of May 2026, the most credible estimates put Olivier Le Peuch's net worth somewhere between $64 million and $83 million, based entirely on his disclosed holdings in SLB (formerly Schlumberger) stock. This overview of Olivier Deschacht net worth helps explain why different trackers can arrive at different estimates. That range comes from three separate trackers, all working from the same SEC insider filings, and all arriving at slightly different numbers depending on the share price date they used and how they counted unvested equity.
Olivier Le Peuch Net Worth: Estimate, Sources, and How to Verify

Who Olivier Le Peuch is (and why getting the right person matters)
Olivier Le Peuch is the Chief Executive Officer of SLB, the world's largest oilfield services company. He was appointed CEO by SLB's board on July 19, 2019, with the role taking effect August 1, 2019. Before that, he held senior leadership positions within SLB across technology, operations, and business lines. He's French by background and has spent essentially his entire career inside SLB's global structure.
The identity question matters more here than it might seem. This site profiles French wealth and business figures, and there are other prominent French executives and family-dynasty names circulating in similar searches. François Chollet’s net worth is often discussed in the same context as other French business figures, but the key is always the underlying disclosures and calculation method. Olivier Le Peuch is not connected to the LVMH or Kering luxury empires, and he's distinct from names like Olivier Chandon de Brailles or Olivier Chastan, who appear in luxury and fashion wealth profiles. Le Peuch's fortune is built entirely in the energy services sector, not luxury goods or retail.
The clearest way to confirm his identity in any database is through his SEC filings. His Form 3 (initial statement of beneficial ownership) and subsequent Form 4 filings are all tied to SLB's CIK number on SEC EDGAR, with his name spelled as "Peuch Olivier Le" in the reporting system. That naming quirk explains why some wealth-tracker sites list him under that inverted format.
Net worth today: the best estimate range
Three financial data platforms have published estimates in 2026, all anchored to his disclosed SLB shareholdings:
| Source | Estimate | As of Date | Method |
|---|---|---|---|
| GuruFocus | At least $64 million | March 16, 2026 | Form 4 share holdings × SLB market price |
| Benzinga | ~$72.4 million | Recent 2026 (page timestamp) | SEC insider holdings data |
| QuiverQuant | At least $83 million | April 29, 2026 | Insider share holdings × market valuation |
The phrase "at least" is doing real work in these estimates. It signals that the trackers are only counting what's visible in public SEC filings: shares he directly owns, shares he has the right to acquire within 60 days (through vested options or restricted stock units), and any shares held by family members or trusts that he's required to report. They are not capturing private investments, cash, real estate, or any assets outside the SLB equity position.
Given that context, a reasonable working range for his total net worth, including reasonable assumptions about savings, diversified investments, and other assets accumulated over a long executive career, would be $80 million to $120 million or more. If you are specifically looking for Olivier Chastan net worth, the best approach is to compare his public filings and reputable tracker methodologies the same way net worth ranges are built here. The disclosed stock position is the floor, not the ceiling.
How net worth is calculated for private wealth (and why numbers differ)
For public company executives, net worth trackers use a simple formula: disclosed shares held multiplied by the current share price. They pull the share count from Form 4 filings (which report every transaction an insider makes, along with their total holdings after each transaction) and multiply by SLB's stock price on whatever date they run the calculation.
That's why QuiverQuant's April 29, 2026 number is higher than GuruFocus's March 16, 2026 number. It's likely the same person, the same shares, but a different SLB share price on a different day. If SLB's stock moved 10% between those dates, the headline net worth moves 10% too.
There's also a definitional issue around what counts as "beneficial ownership." SLB's own proxy statement defines it carefully: shares that may be acquired within 60 days (through options or RSUs) are included, but unvested long-term awards are not. Some trackers include more categories than others, which produces different totals even from the same underlying filings.
What none of these trackers capture is private wealth: cash savings, real estate, diversified financial investments, or assets held through private vehicles. For high-earning executives who have received tens of millions in annual compensation over several years, that untracked wealth can be substantial. Wealth survey methodologies (like those used by Knight Frank's Wealth Report) try to account for this by modeling total wealth accumulation over a career, but those models aren't applied at the individual executive level in publicly available databases.
Where the money comes from
Annual compensation from SLB
SLB's proxy statements include a full CEO compensation table. As a large-cap public company CEO, Le Peuch's total annual compensation package runs into the tens of millions of dollars, combining base salary, cash bonuses, and equity awards (restricted stock units and performance share units). SLB's 2025 and 2026 proxy statements both contain these tables, and they're publicly available on SEC EDGAR. The equity portion is the largest component for most public company CEOs at this level.
SLB equity holdings (the disclosed wealth base)
His directly disclosed SLB shareholding is the single biggest known wealth driver. Every time Le Peuch receives a stock award, exercises options, or sells shares, he files a Form 4 within two business days. These filings build a real-time picture of his SLB equity position. As of the latest available filings, that position is what the $64 million to $83 million range is based on.
Board membership and broader executive benefits
As both CEO and a board member of SLB, Le Peuch receives compensation through both channels. He also benefits from executive perquisites common at large multinationals: retirement plans, deferred compensation arrangements, and benefits that accumulate over time. These don't show up in stock filings but are disclosed in the proxy's "Other Compensation" columns.
Private investments and real estate
This is the unknown portion. An executive who has earned at this level since 2019 (and at senior levels before that) has almost certainly diversified into other assets over time. There's no public record of real estate holdings, private equity positions, or other investments, but it would be unusual for someone at this wealth level to hold everything in a single stock.
What could change his net worth going forward
The biggest single variable is SLB's share price. His disclosed net worth is essentially a leveraged bet on SLB's stock performance, and oilfield services companies are cyclical, tied closely to oil prices, global energy investment cycles, and exploration budgets. A sustained drop in oil prices would compress SLB's earnings, likely hit the stock, and reduce the value of his equity position directly.
- SLB share price movements: the primary driver of the publicly tracked net worth figure
- Vesting of new equity awards: each new batch of RSUs or performance shares that vest adds to his disclosed holdings
- Share sales or diversification: when insiders sell shares (reported on Form 4), the cash is no longer counted in equity-based trackers even though it still exists
- CEO tenure: if he steps down or is replaced, his unvested awards may be affected depending on the terms of his agreement
- SLB's strategic performance: acquisitions, divestitures, or major contract wins affect both earnings and equity value
- Macro energy cycle: oil price direction, global drilling activity, and energy transition pace all feed into SLB's business
One event that often creates a visible jump in net worth trackers is when a large tranche of performance shares vests. These show up as new Form 4 filings, and trackers update their estimates accordingly. Watching for those filings is one of the clearest signals of changes in his disclosed equity position.
Reconciling the different estimates
The gap between GuruFocus ($64 million) and QuiverQuant ($83 million) is not a disagreement about facts. It's a product of three things: the date the estimate was run, the exact definition of beneficial ownership each tracker uses, and whether they include shares acquirable within 60 days or only directly held shares. All three sources are working from the same underlying SEC filings, so they're fundamentally consistent. None of them are wrong; they're just answering the question on different days with slightly different scope definitions.
The safest way to read these numbers is as a floor. The "at least" language used by GuruFocus and QuiverQuant is accurate: these are minimum visible wealth figures based on public equity positions alone. Anyone citing a specific single number as "the" net worth of a private executive is almost certainly overstating their precision.
It's also worth noting that these estimates differ sharply from how private wealth surveys work. A firm like Knight Frank models total wealth by estimating career earnings, savings rates, asset class allocations, and growth over time. That methodology would produce a higher number than a raw share-price calculation, and it would be harder to verify but arguably more complete. No such published estimate exists for Olivier Le Peuch specifically.
How to verify and update the estimate yourself
If you want to track this number yourself rather than relying on third-party sites, here's the process that actually works: The latest public estimates of Olivier Chavy net worth are derived from his disclosed equity and the same SEC filings used by major net-worth trackers.
- Go to SEC EDGAR (sec.gov/cgi-bin/browse-edgar) and search for "Peuch Olivier Le" as the insider name, filtered to SLB's CIK number. This pulls his full filing history.
- Find his most recent Form 4 filing. The last line of the ownership table will show his total beneficial ownership after the most recent transaction.
- Multiply that share count by SLB's current market price (ticker: SLB on NYSE). That gives you the equity-based net worth floor.
- Check SLB's most recent proxy statement (DEF 14A) on EDGAR for the beneficial ownership table, which reconciles all categories of shares including rights to acquire within 60 days.
- Review the proxy's compensation tables to understand the size and structure of his annual equity awards, which tells you what new tranches may be vesting in coming years.
- Cross-reference with GuruFocus, QuiverQuant, or Benzinga to sanity-check your calculation, keeping in mind their "as of" dates.
- For a fuller picture, search SLB's proxy for any deferred compensation balances or retirement plan disclosures that add to visible wealth.
This process takes about 20 minutes the first time and much less once you know where to look. The Form 4 filing date, share count, and transaction price are all machine-readable in EDGAR's XML format, which is why sites like QuiverQuant can automate the calculation. Doing it manually gives you more control over the "as of" date and which share categories you include.
One final point: for context on how this compares to other executives profiled on this site, Olivier Le Peuch's wealth profile is quite different from family-dynasty fortunes tied to luxury goods or generational business empires. If you are also comparing executive-style wealth profiles, see hervé leclerc net worth for a related example of how these figures can be estimated from public and reported information. If you are looking for the latest figures on Olivier Leclercq net worth, they typically trace back to his publicly disclosed SLB shareholdings and how different trackers interpret them Olivier Le Peuch's wealth profile. His wealth is executive compensation-driven, equity-concentrated, and dependent on a publicly traded company's performance. That makes it more transparent than, say, a privately held family fortune, but also more volatile and more dependent on a single stock.
FAQ
Why do different trackers show different olivier le peuch net worth numbers if they use the same SEC filings?
Use a specific “as-of” date. Net-worth pages often update with a new share price but keep the same Form 4 share counts, so two sites can disagree even when the filings are identical. Pick one EDGAR filing date range, confirm the ending total shares (after the last transaction), then multiply by SLB’s closing price on the same date you want to use.
What share categories should I include when verifying olivier le peuch net worth from SEC data?
Treat any “unvested” mention carefully. If you are recreating the math yourself, include only the categories that trackers say count as beneficial ownership and that are actually included by that platform (for example, shares acquirable within 60 days versus only directly held shares). If you include the wrong category, you can overshoot or undershoot by millions.
How can I be sure I’m looking at the correct person when searching olivier le peuch net worth data platforms?
Yes, you can get the identity wrong because some databases store his name in inverted order (for example, “Peuch Olivier Le”). Always match by SLB’s CIK and the SEC reporting entity, not just by the name string, then verify that the transactions are all tied to SLB (ticker SLB) rather than another similarly named executive.
Is it valid to say his net worth rose because a tracker number went up?
Don’t compare numbers across the same year without checking the share-price date used. If the calculation date moves by weeks, SLB’s price swings can materially change the estimate even if his holdings stayed flat. Use the tracker’s “as of” timestamp (or replicate it) before concluding the estimate increased or decreased.
If his disclosed SLB holdings are the floor, how do I estimate the likely “missing” wealth responsibly?
The disclosed stock position is effectively a minimum visible figure. To estimate an upper bound, assume other assets exist, but keep expectations conservative because public disclosures rarely quantify cash, real estate, or private investments for an individual. A practical approach is to model net worth as (SLB equity value you compute) plus a buffer, rather than trying to infer exact amounts from stock filings alone.
What SEC filing events are most likely to create visible jumps in olivier le peuch net worth trackers?
Watch Form 4 timing and the type of award. Stock award grants, option exercises, and sales show as transactions with new holdings totals, while vesting events can create noticeable step changes. If you see a jump right after several Form 4 entries, that’s often the most direct explanation for a tracker updating its estimate.
What’s the most reliable manual method to verify olivier le peuch net worth?
If you want to calculate it yourself, use the share count from the latest Form 4 (the post-transaction holdings number) that falls within your chosen “as-of” window, then multiply by the SLB closing price on your chosen calculation date. For the cleanest result, avoid mixing “holdings after transaction” with “transaction price,” they are different fields.
How should I connect SLB compensation details with changes in his net worth estimates?
Yes, compensation can increase holdings in indirect ways, but it does not automatically map to net worth in a simple one-to-one way. Equity awards can be granted, withheld, sold, or vest into different instruments, and the value only becomes realized or clearly reflected in holdings once you see the related Form 4 updates. Use the proxy for context on compensation, then rely on Form 4 for the actual holdings at a point in time.
How does SLB stock performance and industry cyclicality affect olivier le peuch net worth estimates?
In a cyclical business like oilfield services, net worth tied to SLB equity is more volatile than salary-based wealth. A sustained downturn in oil prices can reduce SLB earnings, pressure the stock, and therefore compress the equity-driven portion of his net worth even if his share count is unchanged. When reading tracker deltas, separate “holdings changed” from “stock price changed.”
