About Us

Quartic Advisory was created to disrupt traditional consulting by bringing practical innovation. We do not throw generic analysis at problems without caring about the output. Instead, every project is driven by senior professionals who take direct personal accountability for real-world execution.

Leveraging Agile principles of fast iteration, transparency and close collaboration, we deliver innovation and high quality. Our remuneration model ties directly to actual outputs and milestones, keeping our interests 100% aligned with yours. This gives us true skin in the game, making us the go-to partner for innovative, high-impact engineering and geosciences.

Expertise

Our team combines capabilities extending to all phases of the subsurface resources exploration and production: hydrocarbon, deep geothermal, underground storage and CCS. Quartic acts from field development and asset acquisition all the way to decommissioning. We rely on a core team with experience from top tier international energy operators and a network of experts supporting us to tackle each challenge.

Geosciences

We deliver comprehensive geological and geophysical expertise across the full asset lifecycle, serving both commercial operators and regulatory bodies. Integrating as a senior-led extension of your subsurface team, we evaluate all basin types, from frontier exploration and prospect de-risking to active field exploitation, geothermal assessments, and CO2 geological storage. We cut through theoretical noise to bring seismic analysis, petrophysical interpretation, structural modelling, well tie-ins, static reservoir modelling, and volumetric risking directly into field development.

Whether conducting rigorous technical due diligence for farm-in and farm-out opportunities, performing local evaluations, or de-risking complex structures for carbon capture, we translate intricate subsurface data into clear, commercially sound decisions. Our practical, execution-focused approach is backed by a proven global track record across all continents, with deep regional experience in Europe, South America, and South East Asia.

Drilling & Well Engineering

We provide total drilling and well technical mastery across every phase of the well lifecycle, bridging the gap between engineering design and rig floor reality. Our senior engineers bring decades of hands-on experience navigating the industry's most complex operational challenges, including deepwater systems, high pressure and high temperature environments, managed pressure drilling, complex completions, and life-of-well interventions. We drive projects from initial Basis of Design and concept selection through to detailed engineering and live, on-site operational supervision.

Beyond front-line operations, we build robust operating management systems, optimize field workflows, and conduct independent compliance audits. We also act as a trusted technical partner to regulatory authorities, providing authoritative oversight for licensing authorizations, operator compliance monitoring, and critical incident investigations. Across the tail end of the asset lifecycle, we bring the same engineering rigour to well integrity management and cost-optimized plug and abandonment.

Subsea Engineering

We deliver end-to-end subsea engineering expertise across greenfield developments and mature brownfield assets alike. Managing every critical hardware and operational boundary, our scope spans early stage FEED, SPS and SURF systems, tie-back feasibility, full decommissioning plans and manufacturing supervision. We stay actively involved through factory acceptance testing, asset integrity monitoring, and complex subsea repair execution to ensure long-term system reliability.

Going beyond the off-the-shelf catalogue, we engineer bespoke subsea tooling, including specialized XMT interfaces, custom ROV tools, and structural removal equipment, guiding execution from initial concept through manufacturing oversight and factory testing. Leveraging a proven track record in decommissioning, we combine strategic innovation with pragmatic execution to deliver streamlined method statements and FEED that eliminate interface friction, de-risk offshore operations, and cut overall capital and operating expenditure.

Commercial & Legal Engineering

We bridge deep technical engineering with sharp commercial and legal rigour. Operating as a senior-led extension of your owner's team, we de-risk contract exposure, streamline procurement, safeguard project economics and run integrated supplier management with a relentless focus on cost control.

We manage the complete commercial workflow end to end: structuring and leading RFIs, RFQs and ITTs, negotiating contract terms, and translating complex engineering scopes into airtight, risk-adjusted EPC, subsea, drilling, and service agreements. For asset acquisitions and farm-in transactions, we conduct forensic technical and commercial due diligence, accurately quantifying subsurface liabilities, abandonment obligations, and historical regulatory compliance to protect your acquisition.

Applied Digital & Data Science

We build pragmatic digital tools at the precise intersection of deep domain expertise and custom software development. By combining in-house software development and UX design with decades of practical field experience, we create tools that engineers and operators actually use. We steer clear of bloated, monolithic enterprise software and generic AI buzzwords, focusing instead on niche visualization apps, custom analytics, interactive dashboards, and task-automating algorithms tailored to real-world operations.

From extracting value out of unstructured legacy reports, logs, seismic datasets, and historical well records, to automating repetitive engineering calculations, we bridge technical domain knowledge with modern agile software delivery. The result is lean, highly intuitive, and deployed into active operations in as little as two weeks.
