Nifty Oil Drilling & Exploration Index — Constituents & Performance

The Oil Drilling & Exploration companies below are the listed Indian Oil Drilling & Exploration universe this page tracks — the same constituent set people search for as the Nifty Oil Drilling & Exploration index. Every figure is equal-weighted across those companies, so one large constituent cannot set the reading. Each number carries its own as-of date.

Participation is spreading downward — the mid and small companies added more this month than the large ones did.

Both lines start at 200 in the same week, so the distance between them is the whole story: the sector line is an equal-weighted index of its 8 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member rebased to 100 at the start and the sector taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover any point to read both values and the gap. This is a description of what the numbers did, not advice.

The central tension: the companies with the most scale are not necessarily the companies creating the most change.

Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.

4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%

Antelopus Selan Energy Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 88.6% evidence confidence.

Deep Energy Resources Ltd has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is guarded: positive earnings, positive 5–60% three-year EPS growth, and a positive P/E are required.

Revenue Scale & Growth Durability

Oil & Natural Gas Corpn Ltd has the highest Revenue among the 10 Oil Drilling & Exploration companies compared here, at ₹6,62,247 crore. Oil India Ltd is next at ₹33,946 crore. Dolphin Offshore Enterprises (India) Ltd has the highest Revenue growth at 76.5%, so level and change sit with different companies.

What the numbers say: Oil & Natural Gas Corpn Ltd is the scale leader at ₹6,62,247 crore, 19.5× the revenue of Oil India Ltd. Dolphin Offshore Enterprises (India) Ltd's growth is 76.5% from a ₹143 crore base, with 15 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

Gap19.5× versus #2 · Oil India Ltd

Persistence4/8 recent comparable periods

Coverage10/10 companies · 139 observations

Investor read: Oil & Natural Gas Corpn Ltd is the scale benchmark; Dolphin Offshore Enterprises (India) Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Oil & Natural Gas Corpn Ltd's growth falls below Dolphin Offshore Enterprises (India) Ltd's for two consecutive comparable reports while operating margin also compresses.

Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

Capacity Spending & Returns On It

No company in this Oil Drilling & Exploration comparison reports capital expenditure on a comparable basis, so there is nothing to rank here — 0 of 10 companies have a usable current reading. The section is shown rather than removed so an unavailable metric is not mistaken for one that was quietly left out. Filings were read through Jun 2026.

CAPEX is cash spent on property, plant, equipment and other reported capital assets. CAPEX intensity divides that spend by revenue; high intensity is a reinvestment signal, not proof that the reinvestment will earn attractive returns.

Withheld from this comparison: Oil & Natural Gas Corpn Ltd (ONGC) — its two data sources disagree by up to 7.6% on reported income across 14 comparable periods, so its derived ratios are withheld; Oil India Ltd (OIL) — its two data sources disagree by up to 78% on reported income across 15 comparable periods, so its derived ratios are withheld; Deep Industries Ltd (DEEPINDS) — its two data sources disagree by up to 92% on reported income across 14 comparable periods, so its derived ratios are withheld. A figure two sources cannot agree on is not drawn — the gap is a decision, not missing data.

Debt Load & Balance-Sheet Headroom

Antelopus Selan Energy Ltd has the lowest Gross debt among the 10 Oil Drilling & Exploration companies compared here, at ₹4 crore. Jindal Drilling & Industries Ltd has the lowest Net debt at ₹213 crore net cash, so level and change sit with different companies. 10 of 10 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Jindal Drilling & Industries Ltd has the clearest covered balance-sheet capacity with ₹213 crore net cash and gross debt of ₹93 crore. Absolute debt alone does not identify the strongest balance sheet because company scale differs; net debt and debt-to-equity carry more information.

Gap0% versus #2 · United Drilling Tools Ltd

Persistence2/2 recent comparable periods

Coverage10/10 companies · 104 observations

Investor read: Prioritize net-cash capacity and leverage relative to operating scale, not the smallest absolute rupee debt.

This conclusion weakens if: Net debt rises faster than revenue and profit for two consecutive reported periods.

Gross debt shows contractual borrowings. Net debt subtracts reported cash; a negative value means net cash. Lower debt can create capacity, but should be read against the scale and capital intensity of the business.

Return On Capital Employed

Antelopus Selan Energy Ltd has the highest ROCE among the 10 Oil Drilling & Exploration companies compared here, at 21.2%. Asian Energy Services Ltd is next at 16.5%. The same company also holds the highest ROCE change, at +10.3 percentage points. 10 of 10 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Antelopus Selan Energy Ltd leads ROCE at 21.2%, 4.7 percentage points above Asian Energy Services Ltd. Antelopus Selan Energy Ltd has the strongest latest improvement at +10.3 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Coverage10/10 companies · 61 observations

Investor read: Antelopus Selan Energy Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Withheld from this chart: Oil & Natural Gas Corpn Ltd (ONGC) — its two data sources disagree by up to 7.6% on reported income across 14 comparable periods, so its derived ratios are withheld; Oil India Ltd (OIL) — its two data sources disagree by up to 78% on reported income across 15 comparable periods, so its derived ratios are withheld; Deep Industries Ltd (DEEPINDS) — its two data sources disagree by up to 92% on reported income across 14 comparable periods, so its derived ratios are withheld. A figure two sources cannot agree on is not drawn — the gap is a decision, not missing data.

Valuation Against Growth & Quality

Antelopus Selan Energy Ltd has the lowest Guarded PEG among the 10 Oil Drilling & Exploration companies compared here, at 0.27×. Oil & Natural Gas Corpn Ltd has the lowest P/E at 7.51×, so level and change sit with different companies. 1 of 10 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Antelopus Selan Energy Ltd has the lowest comparable Guarded PEG at 0.27×. Only 1 of 10 companies pass the guard, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

LeaderAntelopus Selan Energy Ltd · 0.27×

GapNot enough peers

Persistence0/8 recent comparable periods

Coverage1/10 companies · 2 observations

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data sources reconciled. A missing PEG is more honest than a low-base fiction.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/bv signal.

EV/EBITDA includes debt in enterprise value and is useful across different capital structures. P/BV prices the company against its own book. Both are market multiples on reported figures, not intrinsic-value estimates and not forecasts.

Price and relative strength

Price is rebased to 100 inside the selected window. Pair ratio rebases each selected company against one chosen denominator.

Before the conclusion · check the blind spots

What can make this comparison misleading?

This Oil Drilling & Exploration comparison names 8 specific ways its own evidence can mislead, all listed below. 1 of the 10 companies reports on an older date than the sector's freshest reporters, so its rank is marked stale. 4 draw at least one figure from a second feed with too little overlap to cross-check.

Keep these limits visible

A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
1 company has an older fundamental reporting date than the sector’s freshest reporters; its rank carries a stale marker.
4 companies draw at least one figure from a second data feed with too little overlapping history to cross-check against the primary source; they are marked unverified wherever those figures appear.
3 companies are missing from the second-feed metrics by decision, not by absence: the two sources disagree, so nothing from the second is drawn. Read those rows as narrower evidence, never as a weaker business.
Thin comparisons: Capital expenditure, Valuation have fewer than three usable current readings.

10 · the complete set

Which companies are included?

All 10 companies in the canonical Oil Drilling & Exploration membership are listed below, largest market value first — nothing is silently dropped, even where a company reports too little to rank. 2 of these are no longer being priced, so their price and relative strength are frozen at the last traded week shown.

AHEAD means the company is beating the index by 5% or more over three months. LAGGING, FUNDAMENTALS UP means it is 20% or more behind over a year while its trailing twelve-month earnings grew 20% or more. Both rules are fixed and applied the same way in every sector.

How each company's sources stand: 4 of 10 companies draw at least one figure from a second data feed that could not be cross-checked against the primary source, because the two do not share enough reported history to compare. Those figures are marked unverified wherever they appear. 3 of 10 companies have a second data feed that is known to disagree with the primary source, so nothing from it is drawn: Oil & Natural Gas Corpn Ltd (ONGC) — its two data sources disagree by up to 7.6% on reported income across 14 comparable periods, so its derived ratios are withheld; Oil India Ltd (OIL) — its two data sources disagree by up to 78% on reported income across 15 comparable periods, so its derived ratios are withheld; Deep Industries Ltd (DEEPINDS) — its two data sources disagree by up to 92% on reported income across 14 comparable periods, so its derived ratios are withheld.

Evidence and freshness

How was this comparison built?

This comparison is built from the reported filings of 10 Oil Drilling & Exploration companies, normalized to a common ₹ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-07-24. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

FundamentalsThrough Jun 2026 · up to 20 quarters per company

Market dataThrough 2026-07-24 · weekly price and relative-strength history

Derived metricsGrowth, changes, CAPEX intensity, net debt, guarded PEG and P/BV÷ROE are calculated only when their inputs are comparable.

Score confidenceMissing and stale evidence reduces confidence and pulls the 0–100 research-priority score toward neutral.

Source standing1 cross-checked · 6 unverified · 3 withheld, of 10 graded companies.

A second feed is read only after its reported income is matched against the primary source on at least three overlapping periods. Where the two agree the figures fill silently. Where there is too little shared history to compare, the figures are still drawn — they are the only evidence there is — and marked ⚠ unverified everywhere they appear. Where the two are known to disagree, nothing from the second feed is drawn and the affected company is named under the chart it is missing from. Every company's standing is listed in the register above.

Questions investors ask · short, speakable answers

Oil Drilling & Exploration company comparison FAQs

These 18 answers restate the Oil Drilling & Exploration comparison above in question form. Every one is computed from the same 10 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 2026-07-24. Nothing here is estimated, and none of it is a recommendation.

What is the Nifty Oil Drilling & Exploration index?

The Nifty Oil Drilling & Exploration index tracks India's listed Oil Drilling & Exploration companies as a single basket. This page follows the same 10 companies and equal-weights them, so every company's weekly return counts once whatever it is worth, and the reading belongs to the Oil Drilling & Exploration sector rather than to its largest constituent. Figures are as of Jun 2026.

Which are the best Oil Drilling & Exploration stocks in India?

Ranked by this page's four-factor score, Antelopus Selan Energy Ltd places first among 10 listed Oil Drilling & Exploration companies, followed by United Drilling Tools Ltd. That is a ranking of published data — earnings, quality, valuation and market behaviour as of Jun 2026 — and not a recommendation; Sector Alpha is not registered with SEBI as an investment adviser.

How many Oil Drilling & Exploration stocks are listed in India?

This comparison covers 10 listed Oil Drilling & Exploration companies in India, each above the size floor the site applies, with 20 quarters of reported figures per company where the filings exist. The full ranked list is on this page, as of Jun 2026.

Which Oil Drilling & Exploration company is the biggest?

Oil & Natural Gas Corpn Ltd is the largest, with trailing-twelve-month revenue of ₹6,62,247 crore, ahead of Oil India Ltd at ₹33,946 crore. That covers 10 of 10 companies with comparable reporting through Mar 2026.

Which Oil Drilling & Exploration company is growing fastest?

Dolphin Offshore Enterprises (India) Ltd has the fastest revenue growth at 76.5% year on year, across 10 of 10 comparable companies. Fast growth off a small base is not the same as proven scale — check whether the rate holds across several quarters on the chart above before treating it as a trend.

Which Oil Drilling & Exploration company has the best profit margins?

Dolphin Offshore Enterprises (India) Ltd has the highest operating margin at 59%, from 9 of 10 comparable companies. Deep Energy Resources Ltd shows the biggest recent improvement, at +32.5 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

Which Oil Drilling & Exploration company makes the most profit?

Oil & Natural Gas Corpn Ltd earns the most, at ₹49,793 crore of trailing-twelve-month net profit, from 10 of 10 comparable companies. Dolphin Offshore Enterprises (India) Ltd has the fastest profit growth at 44%, though growth off a small or recovering profit base overstates how much has actually changed.

Which Oil Drilling & Exploration company earns the highest return on capital?

Antelopus Selan Energy Ltd leads on return on capital employed at 21.2%, across 10 of 10 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.
