# Oil and gas drilling moves to deep sea: Risks and opportunities As energy sector shifts to deep waters, environmental and economic impacts spark debate. - **Source:** [Nature](https://brifing.si/source/4d850c3b-dd79-4024-bc91-db2571889199) - **Published:** 2026-07-21 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/a51c9981-39b4-4e59-b175-066e62f54b0a ## Deep seas as the new energy frontier With land reserves depleting, oil and gas companies are turning to deep-sea drilling. Waters deeper than 500 meters hold significant potential to meet global energy demand. However, operating in these areas presents major technical and environmental challenges that require innovative solutions. ## Technological advances enabling operations Recent technological breakthroughs have made deep-sea drilling more feasible. Dynamic positioning systems, remotely operated vehicles, and advanced materials now allow access to previously unreachable depths. These innovations are driving increased investment in offshore exploration worldwide. ## Environmental concerns escalate Deep-sea drilling poses substantial risks to unique marine ecosystems. Fragile seafloor habitats, long-term oil spill impacts, and noise pollution worry scientists. The 2010 Deepwater Horizon disaster highlighted these dangers, showing how deep-water accidents can cause lasting environmental damage. ## Economic incentives remain strong Despite high costs, large deep-sea discoveries offer attractive profit margins for companies. Developing nations particularly see these resources as economic boosters. However, price volatility can significantly affect project viability, making long-term planning challenging for energy firms. ## Regulatory gaps persist Comprehensive global standards for deep-sea drilling in international waters are lacking. Current systems relying on national laws and industry self-regulation prove inadequate for environmental protection and worker safety. Experts call for stronger international frameworks to govern these activities. ## Bridge in energy transition Deep-sea resources could serve as transition fuels toward renewable energy. But experts emphasize these must align with climate goals. A balanced approach is needed to ensure these resources support rather than hinder progress toward sustainable energy systems worldwide. ## Sources covering this story - https://www.nature.com/articles/d41586-026-02232-x — --- _Summary written by Brifing from the original reporting.
