HOEC wins Mumbai offshore B-15 block under DSF 2024

What HOEC announced in the Mumbai offshore basin

Hindustan Oil Exploration Company Ltd (HOEC) informed exchanges that it has been awarded a new contract area under the Special Discovered Small Fields (DSF) Bid Round 2024. The awarded block is MB/OSDSF/B15/2024, located in the Mumbai offshore basin. The contract area covers around 332.4 square kilometres. The block lies in shallow water, at an approximate depth of 40 metres. HOEC stated that the area contains two hydrocarbon discoveries, B-15A and B-15-2. The company described these discoveries as having potential for future development and exploration. The award adds to HOEC’s offshore footprint that already includes a Mumbai offshore block.

What is inside the newly awarded block

According to the company’s exchange filing, six wells have been drilled in the awarded contract area. This indicates that the acreage has seen prior exploration work. HOEC highlighted test results from two wells to underline the presence of producible hydrocarbons. The B-15A-1 well produced a flow of around 1.66 million standard cubic feet per day (mmscfd) of natural gas. The same well also produced almost 1,833 barrels of oil per day (bopd). The B-15-2 well yielded almost 1,151 bopd. It also delivered 0.91 mmscfd of gas from the Panna formation. These figures are presented as tested rates, as reported in the filing.

100% participating interest and operator control

HOEC said it has a 100% participating interest in the block and will be the sole operator. For investors, this matters because the operator typically drives technical planning and execution. A 100% interest also means the company does not share its participating interest with a partner in this block. The company indicated that this structure allows it to make all operational decisions for exploration and development. The filing framed this as strengthening HOEC’s ability to move the asset forward. However, the company did not disclose financial details linked to the contract in the cited report. That limits visibility on timelines, capex, or project economics at this stage. What is clear from the filing is the asset’s size, water depth, and the tested well performance figures.

How this fits with HOEC’s existing Mumbai offshore presence

HOEC’s announcement positioned the new block as a complement to its existing Mumbai offshore asset, MB/OSDSF/B80/2016. The company already has exposure to offshore development through B-80. With the addition of MB/OSDSF/B15/2024, HOEC said its overall offshore area rises to more than 800 square kilometres. This is a portfolio statement, not a production guidance. It suggests that HOEC is expanding its operated offshore acreage within the same basin. Such consolidation can simplify operational focus, depending on infrastructure and development plans. The disclosure does not specify whether the two blocks will share facilities. It also does not specify the next milestones, beyond the fact of contract award.

Snapshot of HOEC’s offshore assets mentioned

The article content also references other offshore assets associated with HOEC. One is B-80, a joint venture in which HOEC holds 50% and Adbhoot Estates holds 50%. The B-80 block was won in the Arabian Sea during DSF Round-I held by the Directorate General of Hydrocarbons. Initial data acquisition and exploratory activities for B-80 were conducted by ONGC, as described. The joint venture developed a Field Development Plan (FDP) after the field was assessed as viable for production. Another asset referenced is PY-1, described as a gas-bearing offshore fractured granitic basement reservoir in India. PY-1 covers an area of about 75 sq km and has 100% participating interest with HOEC. It is also described as the only offshore platform in the Cauvery Basin with 8 slots and four wells drilled.

Stock move and market references around the announcement

A separate market report stated that shares of Hindustan Oil Exploration Company rose 3% to 176 rupees after the company said it won a contract to explore a new oil and gas block in the Mumbai offshore region. That report also noted that the company did not provide financial details. It added that other explorers such as Vedanta, ONGC, and Oil India also signed contracts. Elsewhere in the provided content, the share price is also shown as Rs 158.11 and as ₹156.20, indicating different reference points or timestamps. The company’s market capitalisation is stated as ₹ 2065.64 in the material provided. Readers should treat these prices as point-in-time values from the cited snippets, not a single uniform “current price.” The core event remains the award of MB/OSDSF/B15/2024 and the disclosure of key technical parameters.

Key facts table

Why the development matters for HOEC and the sector

The DSF framework is designed to bring discovered small fields into development by awarding contract areas to operators. In this case, HOEC’s award comes with two named discoveries and a record of wells already drilled, which can reduce early-stage geological uncertainty compared with purely frontier acreage. The shallow water depth of around 40 metres can also influence offshore development design and logistics, although the company has not provided a project plan here. The fact that HOEC is the sole operator with 100% participating interest makes the block strategically important because it concentrates decision-making and accountability. The disclosure also shows HOEC’s continued focus on offshore assets alongside its other Indian portfolio, which spans multiple states as described in the supplied text. Importantly, the market report explicitly noted the absence of financial details, so conclusions on profitability or timelines cannot be drawn from this information alone. What investors can take from the filing is the scale of the acreage, the existence of past drilling, and the tested well rates cited.

Conclusion and what to watch next

HOEC’s award of MB/OSDSF/B15/2024 adds a 332.4 sq km contract area in the Mumbai offshore basin with two discoveries and six drilled wells already on record. The company has full participating interest and will operate the block, while also holding an existing Mumbai offshore block, MB/OSDSF/B80/2016. Alongside references to B-80 and PY-1, the disclosures underline HOEC’s offshore positioning across India’s west and east coast basins. Near-term updates to watch will be any further exchange filings on work programmes, development planning, or timelines for exploration and appraisal in the new block. Investors will also look for any future clarity on capital allocation and commercial terms, since the market report cited no financial details with the contract announcement.
