For years, carbon capture in California has been mostly talk: permitting, policy and pilot projects. That's starting to change. CRC has begun injecting CO₂ at Carbon TerraVault, storing emissions more than a mile underground in depleted oil and gas reservoirs. Not a pilot, but an operational project that could eventually store up to 1.46 million tonnes of CO₂ a year, roughly the emissions of 350,000 cars. California has some of the world's most ambitious climate targets, but heavy industry, hydrogen and carbon removal all depend on permanent CO₂ storage. With the state's first Class VI permits and commercial-scale storage now underway, California is finally moving from planning to deployment. That's a milestone worth paying attention to.

The field next door isn't always your best analogue. Whether it's a nearby field, a well-known development, or an industry favourite, engineers often start with the references they know best. What happens when the search goes wider? Read the full article below. belltreegroup.co.uk/your-nea…

The most consequential exploration opportunity in your portfolio may already be on production... 🌎 Global average recovery factors for conventional oil sit between 20 and 40%. In most mature fields, the majority of original oil in place remains unproduced, not because the geology won't yield it, but because the workflows used to pursue it were built for a different phase of field life. The hashtag#IEA's analysis of over 15,000 producing fields puts the average post-peak decline rate for conventional oil at 5.6% per year. Arrest that decline, or partially reverse it, and the value creation at field scale is material. That is the opportunity LTRO is designed to capture. 👉 Locate the Remaining Oil is an integrated workflow that treats the reservoir, not the well, as the unit of optimisation. It begins with a rigorous dynamic model reconciliation against individual well performance history, maps residual saturation and bypassed pay systematically, and delivers an intervention sequence ranked on risk-adjusted return with subsurface uncertainty built in as a primary input, not a late-stage sensitivity. 🎯 The result is a structured, technically-grounded path from current recovery factor to a credibly higher one, with the sequencing and economic logic to support capital allocation decisions. For mature asset teams who know the resource is there and are looking for a disciplined framework to go after it, it is worth a conversation. Happy to share how this has been applied to fields with comparable subsurface characteristics, and to hear where you see the clearest remaining upside in your asset base.

Has it ever happened that the assets with the most uncertainty also carry the most upside? 💬 That’s where things get interesting, and where they get risky. In practice, decisions are still anchored in what looks reliable, familiar analogues, stable models, consistent forecasts. The more stable the outputs, the easier they are to trust. But stability is not certainty. In many cases, the real upside sits outside that frame, in the parts of the subsurface that are underrepresented or simply not captured in the data. So the question isn’t just where the opportunity is. It’s how much of it sits in the uncertainty we’re not explicitly modelling. That’s where upstream analytics needs to shift, from refining what we already know to making what we don’t know visible. 👉 Tools like bMark are designed to do exactly that.

✔️ India, an SPE panel, and some great conversations. A good week for Belltree. Andrew Berrow was in hashtag #Mumbai for the #SPE International Symposium on The Future of Energy Decisions, joining industry leaders on the data analytics and production optimization panel. Alongside the symposium, Andrew met with partners to explore how hashtag#bMark™ Upstream Analytics and bMark™ CCS can support real world operations. The pace of AI and data adoption in India’s energy sector is accelerating, and expectations are rising just as quickly. If you're exploring how data can drive better upstream decisions, let’s connect: lnkd.in/eW7Fr-Eh 👉Learn more about what we’re building at Belltree: lnkd.in/evYfMC2A #oilandgas #energytransition #ccus #bMark #SocietyofPetroleumEngineers

Around 70% of global oil and gas production now comes from mature fields. The energy transition was expected to reduce reliance on ageing assets, but capital discipline and constrained exploration are increasing dependence on existing assets.The real risk now sits in late-life portfolio decisions. Where should operators focus most? 💬

77... That’s how many CCUS projects are now operating globally 🌎 . a landmark shift from scattered pilots to true industrial deployment. And with capture technologies rapidly diverging in 2025 from low‑energy solid sorbents to hybrid systems and durable membranes, each with different efficiency and operating profiles, the real technical challenge for 2026 isn’t capturing CO₂. 👉 It’s identifying where it should be stored for maximum long‑term performance. bMark is built for that challenge. It pinpoints the best CO₂ storage options using geological, operational, and capture‑system data. Book a bMark demo and start 2026 with decisions grounded in real technical certainty. lnkd.in/ey2GQKPQ
