    Quaise superhot geothermal plant: design and subsurface risks for engineers

    Quaise superhot geothermal plant: design and subsurface risks for engineers

    First reported on MINING.com

    30 Second Briefing

    Quaise Energy is advancing Project Obsidian in Oregon, aiming to build the first superhot geothermal plant by drilling into rock above 300°C and delivering a baseload 50 MW from only a handful of wells by 2030. A modelling analysis presented at the 2026 Stanford Geothermal Workshop by senior mechanical engineer Daniel W. Dichter indicates higher subsurface temperatures could ultimately support 250 MW in phase two, with a regional goal of 1 GW. The confirmation well is due online later this year, with lab work at Oregon State University recreating extreme downhole geochemical conditions.

    Technical Brief

    • Superhot geothermal target is rock exceeding 300°C, demanding tools and completions tolerant of >572°F environments.
    • Modelling work focuses on unknown geochemistry at unprecedented depths/temperatures, including fluid–rock reactions affecting permeability and casing.
    • Dichter’s paper benchmarks projected well power output against exceptionally productive oil and gas wells for equivalence.
    • Confirmation well scheduled this year will provide first in situ data on temperature gradients and geochemical regime.
    • Operationally, each well is intended to deliver continuous baseload output, shifting geothermal design towards high-enthalpy, low-well-count fields.
    • Scope remains constrained by first-of-a-kind uncertainties: rock chemistry, long-term material durability and model extrapolation beyond existing geothermal datasets.

    Our Take

    With a 1 GW build-out goal for superhot geothermal energy in the USA, Project Obsidian would sit at the upper end of power scales normally seen in our geotechnical project coverage, more in line with large gas or coal units than typical geothermal plants, which has implications for grid integration and transmission planning.

    The explicit comparison to oil and gas in the article facts signals that Quaise Energy is targeting depths and temperatures more familiar to hydrocarbon drillers, which could open a new service market for existing US drilling contractors rather than relying solely on traditional geothermal specialists.

    The mention of a 0.5% rise in copper stocks on Comex alongside a 1 GW geothermal ambition underlines a tension already visible in our database: large-scale renewable projects in the USA and Peru are emerging just as copper-market signals remain finely balanced, which may influence long-lead procurement for cabling, transformers and heat-exchange equipment.

    Inter Helix Spacing in Helical Piles: design implications and torque guidance

    Inter‑helix spacing for helical piles and anchors is traced from early empirical rules of thumb (typically 3× helix diameter) to current design approaches based on cylindrical shear and individual bearing models. The review compares performance implications of close spacing (overlapping stress bulbs, higher installation torque, potential group behaviour) versus wider spacing (reduced interaction, deeper embedment, more steel), and links them to torque‑to‑capacity correlations. For practitioners, it clarifies when legacy spacing rules remain adequate and when soil type, load regime, and installation constraints justify project‑specific optimisation.

    TAS stadium works: Macquarie Point contract and ground risks for engineers

    Tasmania’s Government has let a contract to dismantle and compact the early‑20th‑century Goods Shed at Macquarie Point to clear the site for a $1.13 billion multi‑purpose stadium in Hobart. The former rail and port freight hub will be packed down to formation level, providing a prepared platform for the stadium’s deep foundations, services corridors and future transport interfaces. Geotechnical teams will need to manage demolition spoil, variable fill and potential contamination typical of historic industrial waterfronts before main works can proceed.

    Keller North America engineer programme: design–build skills lens for geotechnical teams

    Keller North America has expanded its field engineer / project engineer development programme after a successful pilot, formalising a structured path from site-based roles into project management and technical leadership. The scheme combines intensive on-the-job training on ground improvement and deep foundation projects with rotations through estimating, design, and operations, exposing graduates to tools such as geotechnical instrumentation, grout mix design, and pile load testing. For contractors and clients, the move signals a pipeline of early-career engineers with stronger design–build integration skills and site-ready competence.
