Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

There is a minor drift between the high-level Signal of being a ‘geographically diverse’ leader and the Sustainability sub-pages, which lean heavily on aspirational jargon rather than the hard data seen on the Homepage and What We Do pages. While the homepage promises strategic growth through the LLOG acquisition, the Sustainability pillar feels like a mandatory corporate overlay rather than an integrated operational reality, using terms like ‘lower carbon world’ without immediate technical pathways.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

Sustainability

Our purpose is to play a significant role in meeting the world’s energy needs through the safe, efficient and responsible production of hydrocarbons, while creating value for our stakeholders. In support of this, we are guided by our approach to sustainability.
Our sustainability approach focuses on three pillars:

[H2] Prioritising safety

We are committed to the safety and wellbeing of everyone who works with Harbour. In practice, this means we promote a culture of safety and wellbeing across our operations.
We have comprehensive health and safety processes which we use to track and mitigate risks across our operations on a daily basis. We strive to always do better, and are working towards the goal of zero incidents.

Safety

[H2] Reducing our impact on the environment

We are focused on reducing our gross operated Scope 1 and 2 CO2e emissions by 50% by 2030 against a 2018 baseline, in line with our aspiration to be net zero by 2050. We invest in carbon storage and have a leading position in Europe.
Additionally, we factor potential impacts to the environment into our plans, procedures and decision making.

Environment

[H2] Supporting our stakeholders

We are respectful, fair and transparent with our people, communities in which we work, investors and other stakeholders. This includes respecting human rights, upholding the highest ethical and governance standards and promoting diversity, equity and inclusion.
We help our communities prosper and drive responsible practices in our supply chain.

Stakeholders

[H2] ESG reporting

What we do

Harbour Energy has built a unique position as one of the world’s largest and most geographically diverse independent oil and gas companies, with operations spread across five continents.

[H2] Maximising production

Harbour Energy is active in 10 countries with significant operations in Norway, the UK, Argentina, Germany and Mexico:In Norway, Harbour is now the sixth largest producer, and the country is our largest source of production.In Argentina we have an interest in the CMA-1 concession, which today produces c.15% of Argentina’s natural gas production. We are one of the UK's largest oil and gas producers, representing c.15% of the country’s domestic oil and gas production.In Germany we own and operate 100% of Mittelplate, the country’s largest oil field.  We have a significant interest in Mexico’s strategically important Zama project, which has the potential to replace reserves equivalent to a year’s worth of our production.

[H2] Our portfolio

Our portfolio is well balanced with a mix of oil and gas and no single hub accounting for more than 10% of our production.
We directly operate around 40% of our production and we have extensive global operational experience and capabilities. We have a track record of investing in our asset base to extend field life and offset natural production decline.
In our non-operated portfolio, which mainly comprises high quality, long-life assets, we partner with well-established operators, including Equinor, Aker BP and Vår Energi in Norway, BP in Egypt and TotalEnergies in Argentina. In addition, some of our joint venture partnerships have existed for multiple decades, such as in Argentina, where TotalEnergies and Wintershall Dea partnered for more than 45 years.

[H2] Case study: Armada Area, UK

The Armada Area fields in the UK North Sea, which we acquired from Shell in 2017, were scheduled for decommissioning in 2018. We saw the opportunity to invest in the asset through additional drilling, which extended field life. The drilling of an infill well at North West Seymour has the potential to further extend Armada’s producing life to beyond 2030. In 2025, we conducted additional studies on several assets to identify optimum emissions reduction strategies.

[H2] Reserves and resources

At Harbour, we focus on maximising the value of our existing infrastructure and assets to increase our production and replenish our reserves and resources – in other words, we do more with what we have and where we already excel.
By using our knowledge and experience of the geology and subsurface conditions in the areas we operate in, we use our production assets   efficiently while also lowering the risk involved in expanding our portfolio and developing our resources more quickly.

[H2] Pipeline

Our pipeline of opportunities now spans:

[H3] 2P reserves:
1.12billion barrels of oil equivalentOur proven and probable reserves include opportunities to increase near-term production in Norway, to expand around our operated hubs in the UK and to sustain output from our German operations, for example with infill projects. We also have significant gas reserves providing opportunities for growth in Argentina.

[H3] 2C contingent resources:
1.84billion barrels of oil equivalentOur 2C resources underpin future production and cash flow. These resources include near-infrastructure opportunities, conventional, offshore projects in Mexico, Norway, Argentina, Egypt and Indonesia, and scalable, unconventional opportunities in the Vaca Muerta onshore shale play in Argentina.

[H2] Carbon capture and storage

Carbon capture and storage (CCS) is a proven technology with enormous potential to help decarbonise the economy, particularly in hard to abate sectors such as heavy industry and power.
CCS has been in use for more than four decades and is one of the few methods we have to remove CO2 from the atmosphere at the scale needed. It involves capturing CO2 directly at the source from power stations or industrial plants before being transported by pipeline and injected into rock formations, such as saline aquifers or depleted oil and gas reservoirs, where it can be stored safely for thousands of years.
The Intergovernmental Panel on Climate Change says CCS is vital to achieve the ambitions of the Paris Agreement and limit future temperature increases to 1.5°C above pre-industrial levels.
Harbour has built a strong position in CCS. We have interests in some of Europe’s most advanced and promising projects that have hundreds of millions of tonnes in existing and planned capacity. We also have licences to explore additional long-term storage opportunities.
