COMPARISON

Why Choose Us Over Others

Why Choose Us Over Others

See how we compare against others in performance, growth

See how we compare against others in performance, growth

We’re not tied to any single supplier. We source, integrate, and deploy the right technologies from across the industry

Our compact, highly skilled teams offer specialized services designed around your well, not a corporate template.

Quick to mobilize, quick to decide — no red tape, just results.

We integrate the best tools and systems from multiple vendors to deliver what works best — not what we’re told to sell.

Every job is unique; our designs and workflows are built around your field, not a standard playbook.

Others

Slower execution and longer setup

Their systems and fluids are built to fit their catalogue, not your well conditions.

You pay for layers of management, branded logistics, and legacy infrastructure — not necessarily better service.

Changing a plan mid-operation can take days, not hours. With us, decisions are made in real time on the wellsite.

You become one job in a global pipeline — not a priority partner.

We are focussed on building a portfolio of conventional, production-led, oil & gas assets within Europe. H2Oil is committed to exploring its licenses safely and with due regard to the amenity of local residents and to the environment.

H2Oil’s EIV-1 asset, located in the Suceava licence area of north eastern Romania, represents a strategic step into upstream ownership through a non-operated interest alongside the company’s established well-services activities.

The licence includes the Bainet gas discovery and associated producing zone, with historical production of around 15,000 m³/day, demonstrating strong deliverability from the field. By securing a 50% economic interest, H2Oil has established a valuable onshore Romanian position with clear potential for further development, production optimisation, and long-term growth.

The asset strengthens H2Oil’s European footprint and allows the company to leverage its engineering, well-testing and completions expertise to support maximising the field’s performance and commercial potential.
