Flash Summary: Deep Industries is the oil-and-gas services company that nobody reads about because it doesn’t have a consumer app. But Q3 FY26 threw a party: revenue up 43% YoY to ₹222 crore, PAT up 50% to ₹71.3 crore, EBITDA margins fat at 48%. The stock is at ₹410, trades at 11.3x P/E (industry median: 11.3x), and has a ₹1,402 crore production-enhancement contract with ONGC. Then a wellhead said “nope” and leaked gas. But here’s the wild part: the market barely blinked. This is a company with ₹3,000 crore in order book, 12% ROE, and less fanfare than a new cricket betting app.
02 — Introduction
The Unsexy Business of Keeping India’s Oil & Gas Flowing
Deep Industries Ltd. Incorporated in 1991. Covers 70%+ of post-exploration oil-and-gas services in India. Makes zero noise on social media. Has zero celebrity brand ambassadors. But every time a state wants to extract oil or pump gas through a pipe, this company’s name is on the shortlist.
The company does five things: gas compression (rents compressors on charter basis), gas dehydration (removes water from natural gas), drilling and workover rigs (drills holes or fixes existing ones), integrated project management (does the whole thing in one go), and now — production enhancement services (helps mature oil fields produce more by optimizing extraction).
ONGC is 54% of their revenue. Oil India, Vedanta, and GAIL make up the bulk. Government PSUs and big oil companies don’t buy shares in Deep Industries because the CEO is charismatic. They buy services because Deep owns the rigs, owns the compressors, has 30+ years of operational experience, and delivers projects faster than competitors — 4-6 months vs. 10-12 months industry-wide. That’s the entire moat.
Management said in the Feb 2026 concall: they’re “not chasing activity, but disciplined execution, asset reliability and capital efficiency.” Translation: they know they’re boring, and they’re fine with it.
Market Position Check: 70%+ of India’s post-exploration oil-and-gas services market. That’s not 70% of a tiny niche. India produced ~600 MMBBL of oil in 2023. That’s over $40 billion of value in the upstream ecosystem alone. Deep is the plumbing contractor to that ecosystem.
03 — Business Model: WTF Do They Even Do?
Renting Holes, Compressing Gas, and Making ₹1 Billion Feel Easy
Here’s the simple version: Deep owns physical assets (rigs, compressors, dehydration units). It hires these assets out to ONGC, Oil India, Vedanta, and other oil-and-gas explorers at daily rates or long-term charters. The asset is paid for in 3-5 years, then it’s mostly gravy.
Gas Compression (Revenue driver #1): Oil companies extract crude and natural gas from underground. Before pumping that gas through pipelines, water needs to be removed (else it corrodes pipes). Deep owns compressors. ONGC rents them. Daily rate: hundreds of thousands of rupees, depending on the unit size. Multiply by 365 days, multiply by multiple units deployed, and you get ₹50-80 crore per year just from compression.
Drilling & Workover Rigs (Revenue driver #2): When ONGC wants to drill a new well, they hire Deep’s drilling rigs. When an old well needs to be “worked over” (re-perforated, cleaned, fixed), they hire Deep’s workover rigs. Each rig can generate ₹2-3 crore per year depending on day rates and utilization. Deep has 11 workover rigs and 6 drilling rigs as of June 2025.
Gas Dehydration & Processing: More specialized, lower volume, but high margins. Deep builds dehydration units and operates them on charter basis. Emerging business, but contribution is growing.
The New Kid: Production Enhancement Services: In December 2024, ONGC handed Deep a ₹1,402 crore, 15-year contract. This is different. Instead of just renting a rig, Deep now operates ONGC’s mature Rajahmundry field outright. Fixed monthly fee + 64% of incremental production above baseline. This is a recurring revenue play with upside leverage if they optimize production.
Gas Compression~35%of revenue
Drilling/Workover~40%of revenue
Gas Dehydration~12%of revenue
Asset Deployment88-95%utilization rate
Management called themselves “asset-light” compared to integrated oil companies, but they’re actually “asset-heavy” compared to software companies. They own ₹1,426 crore in fixed assets as of Sep 2025. That’s the moat. That’s also the leverage. When crude oil prices rise, oil companies drill more, need more rigs, Deep’s utilization goes up, ROCE improves. When crude prices crash, the reverse happens. The company oscillates between feast and famine every few years. Currently? Feast mode.

What’s Actually Happening: Revenue is growing 40%+ YoY, PAT is up 50%, and EBITDA margins are running hot at 47-48%. This is a company that’s firing on all cylinders. But here’s the asterisk: the well incident (Well Mori #5 at ONGC’s Rajahmundry field in early Jan 2026) happened after Q3 closed. Management said it cost them ₹5-6 crore in deferred Q4 revenue. Not a catastrophe, but it’s a reminder that this business has operational risks.
💬 With 11.3x P/E and 12% ROE, why isn’t Deep Industries trading at 15-18x like other mid-cap oil services companies? Is it ONGC concentration risk, or market just hasn’t discovered it yet?
05 — Valuation Discussion: Fair Value Range
What Is This Boring Hole-Drilling Company Actually Worth?
Method 1: P/E Based
Annualised EPS (average of Q1-Q3) = ₹40.48. Current P/E = 11.3x. For oil-services companies with 12-13% ROE and lumpy cash flows, a 10-14x P/E is justified. Industry median P/E is 11.3x, so Deep is exactly at median.
→ 10x × ₹40.48 = ₹405 14x × ₹40.48 = ₹566
Range: ₹405 – ₹566
Method 2: Price to Book Value
Book Value = ₹302. Current P/BV = 1.36x. For asset-heavy industrial services companies with 12-13% ROE, 1.2-1.8x P/BV is reasonable. Given the large order book and quality of ONGC contracts, upper band is justified.
→ 1.2x × ₹302 = ₹363 1.8x × ₹302 = ₹543
Range: ₹363 – ₹543
Method 3: EV/EBITDA (Annualised)
TTM EBITDA = ~₹330-340 Cr (rough annualization from recent qtrs). EV = Market Cap + Net Debt = ₹2,622 Cr + ₹205 Cr debt – cash = ~₹2,700-2,750 Cr. EV/EBITDA = ~8.1x. For growth-phase oil services, 8-12x is reasonable.
Implied at 8x-12x EBITDA: ₹387-₹558 range.
Range: ₹387 – ₹558
Consolidated View: Across all three methods, the fair value range clusters around ₹385-₹560. The CMP of ₹410 sits right in the middle of the range — suggesting the market has already priced in much of the good news (order book, growth rates) and a decent chunk of the risks (well incidents, ONGC concentration). Upside is capped until ROCE improves above 14% or order book exceeds ₹4,000 crore sustainably.
