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.

Oil Drilling & Exploration, equal-weighted, based at 200 NIFTY 500, same base, same start trailing 12-month earnings per share rising falling

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.

03 · sector relative strength, before individual stocks

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 93% evidence confidence.
Deep Energy Resources Ltd has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.
How this score is built, and what the marks mean

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led NIFTY 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step curve the sector itself is placed on — basing, turning, breaking out, leader, fading, asleep — read from how many weeks running it has led NIFTY 500 and whether that lead is widening or shrinking. It describes where the PRICE stands, not the earnings trajectory and not a recommendation, and it is left blank for a company whose weekly history is too short or too stale to read.

05 · what price has already done

Market action

Asian Energy Services Ltd has the strongest one-year price move in Oil Drilling & Exploration at +39.9%. Deep Energy Resources Ltd leads on Mansfield relative strength against NIFTY at +40.7%. 8 of 10 covered companies are above zero on that measure. Every line covers 313 weekly closes through 2026-07-31.

Price and relative strength

Every company, the sector's own index and NIFTY 500 all start level on the left edge of the window, so only the distance between the lines counts — the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.

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.

Coverage10/10 companies · 141 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.

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 Jun 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.

LeaderAntelopus Selan Energy Ltd · 21.2%
Gap28.5% versus #2 · Asian Energy Services Ltd
Persistence1/1 recent comparable periods
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 PEG among the 10 Oil Drilling & Exploration companies compared here, at 0.27×. Oil & Natural Gas Corpn Ltd has the lowest P/E at 7.32×, so level and change sit with different companies. 1 of 10 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Antelopus Selan Energy Ltd has the lowest comparable PEG at 0.27×. Only 1 of 10 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

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 feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

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: Valuation have fewer than three usable current readings.

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 2026-07-31. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

Derived metricsGrowth, changes and PEG 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.
How a second data feed is admitted, and what happens when it disagrees

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.

Oil Drilling & Exploration company comparison FAQs

These 24 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 2026-07-31. Nothing here is estimated, and none of it is a recommendation.

Is the Oil Drilling & Exploration sector outperforming NIFTY 500?

Oil Drilling & Exploration has outperformed NIFTY 500 by 14.7% over 52 weeks and 7.3% over 13 weeks. 8 of 10 covered companies beat NIFTY on Mansfield relative strength, while 4 of 9 beat the sector itself.

Which Oil Drilling & Exploration company has the strongest 4-Factor Sector Score?

Which Oil Drilling & Exploration company has the lowest comparable PEG?

Antelopus Selan Energy Ltd has the lowest comparable PEG at 0.27, among 1 of 10 companies whose earnings and growth are steady enough for the ratio to mean anything.

How much history does this Oil Drilling & Exploration comparison include?

The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Jun 2026. Missing observations remain blank rather than being estimated.

How is the 4-Factor Sector Score calculated?

The four visible contributions add directly: growth and earnings up to 35 points, capital efficiency up to 25, valuation up to 20, and relative strength up to 20. Missing or stale evidence moves only the affected contribution toward neutral.

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 Deep Industries 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 has the best profit margins?

Antelopus Selan Energy Ltd has the highest operating margin at 70%, 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. Antelopus Selan Energy Ltd has the fastest profit growth at 100%, 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.

Which Oil Drilling & Exploration stock is the cheapest?

On PEG — where a LOWER number is cheaper — Antelopus Selan Energy Ltd screens cheapest at 0.27×. Only 1 of 10 companies have earnings and growth steady enough for the ratio to mean anything, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.

Is the Oil Drilling & Exploration sector beating the market?

Oil Drilling & Exploration has outperformed NIFTY 500 by 14.7% over the last 52 weeks and 7.3% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 8 of 10 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

Which Oil Drilling & Exploration stock has the strongest price momentum?

Deep Energy Resources Ltd has the strongest relative strength against NIFTY 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

Which Oil Drilling & Exploration company scores highest for research priority?

Antelopus Selan Energy Ltd scores 86.8 out of 100 with 93% evidence confidence, from 32.2 points on growth and earnings, 21.5 on capital efficiency, 15 on valuation and 18.1 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

How many Oil Drilling & Exploration companies does this comparison cover, and over what period?

It compares 10 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

What is the total market cap of the Oil Drilling & Exploration sector?

The 10 Oil Drilling & Exploration companies on this page carry ₹3,95,334 crore of combined market value. Oil & Natural Gas Corpn Ltd is the largest at ₹3,05,110 crore, about 77% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-05.

What is the Oil Drilling & Exploration sector's P/E ratio?

The median price-to-earnings ratio across the 10 Oil Drilling & Exploration companies on this page is 20.6×, measured on the 9 that report a comparable figure. A sector-level history for this multiple is not held here, so this is a cross-section of today, not a comparison with the sector’s own past. Figures are as of 2026-08-05.

How is the Oil Drilling & Exploration sector performing?

8 of the 10 covered Oil Drilling & Exploration companies are beating NIFTY 500 on Mansfield relative strength. The sector itself is 14.7% ahead of NIFTY 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-08-05.

Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
