Facts and figures
General information about NAM
- NAM has two shareholders: Shell (50%) and ExxonMobil (50%). NAM applies Shell’s operational processes and safety systems.
- Energie Beheer Nederland (EBN) is a Dutch Government-owned company that plays a key role in oil and gas production in the Netherlands. In that context, it has a 40% stake in almost every oil and gas project.
- Total natural gas production by NAM in 2011: 61.3 billion m³ (around 75% of overall natural gas production in the Netherlands).
- Total petroleum production in 2011: 431,000 m³.
- Workforce: 1700; 47 nationalities; indirect employment: around 5000.
- Total energy consumption in the Netherlands: 45% from natural gas.
- Fifty-six percent of the European Union’s natural gas reserves occur in the Netherlands.
- NAM is producing natural gas from more than 175 fields, onshore and offshore.
- An average household consumes 1,600 m³ of natural gas each year.
- To date, gas production has contributed more than EUR 200 billion to the Dutch treasury.
- One of the world’s largest gasfields. Surface area of the Groningen field: 900 km².
- Total production volume of the Groningen field: 2,800 billion m³.
- NAM anticipates producing natural gas from the Groningen field for at least another 50 years.
- Surface area of the gasfield: 900 km².
- Number of wells drilled: approx. 300, across 20 production sites.
- Gas volume produced to date: 2,020 billion m³ (December 31, 2012).
- Gas volume yet to be produced: 780 billion m³ (December 31, 2012).
- Annual production in 2012: approx. 49 billion m³.
Small Fields Policy
- Dutch Government policy since the oil crisis (1973-74): spare the Groningen field and first prospect for and produce natural gas from as many small fields as possible.
- This will enable the Groningen field to fulfil a special role for a longer period of time – buffer field – if demand for gas is higher than the total supply from the small fields, the Groningen field will make up the difference. The small fields currently account for approx. 30% of annual production; the Groningen field accounts for approx. 70%.
- The Small Fields Policy has meant that a volume of natural gas half the size of that of the Groningen field has since been found in the small fields.
- This means that the Groningen field is still almost half full; the Groningen field would otherwise be almost empty by now.
- 19 offshore locations and 4 monotowers
- 500 wells
- All platforms are connected to a pipeline
- The pipelines come ashore at Den Helder
- Many of our offshore operations are carried out by AJS
- Den Helder is one of Europe’s largest natural gas processing stations.
- The facility processes 19.5 billion m³ natural gas each year.
Natural gas storage underground
- Set up in the mid-1990s
- Continuing production has meant: a drop in pressure in the Groningen field
- This has resulted in a reduction in production capacity (lower volume of gas can be produced from the field on a daily basis)
- The Groningen field is no longer able to provide adequate support during extremely cold periods.
- Underground gas storage acts as a buffer during periods of peak demand.
- The theory: fill up empty fields designated for natural gas storage during the summer to ensure they are at the correct pressure – this will enable large volumes of natural gas to be recovered quickly during the winter.
- Grijpskerk: - Injection capacity: 12 million m³/dayn - Production capacity: 55 million m³/day
- Langelo: - Injection capacity: 24 million m³/day - Production capacity: 51 million m³/day
