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.

Groningen gasfield

  • 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.

Offshore

  • 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
