Feature
Gas content is associated with Permian deposits. It is connected with a large gently sloping arch, in the core of which lies a salt mass. The section of sediments forming the arch is characterized by a sharp decrease (up to 200 m) in the thickness of Jurassic deposits .
It is believed that the residual gas reserves in the field are 2.7 trillion m³, cumulative production is more than 1.5 trillion m³. The field has 300 wells. Groningen gas contains 81% methane and 14% nitrogen , which makes it ideal for use in the Dutch gas pipeline network.
Economic Significance
The development of the field was expensive enough and it needed a lot of state support to build a network of gas pipelines and change the rules of trade in the gas market: introduce the “ take or pay ” principle and link gas prices to oil prices . [1] Due to the discovery of this field, its rapid development and its profitability, the gas sector in the Dutch economy has become very significant. The country's economy has become very dependent on gas production. This effect is called the “ Dutch disease ”.
Earthquakes
Since 1994, the deposit area has experienced more than 900 earthquakes of magnitude up to 3.6 points. [2] The relationship of earthquakes to field development has been proven. The Dutch government tightened gas production standards and set a date for the forced shutdown of the field in 2030.
Field Operator
The operator of the field is Nederlandse Aardolie Maatschappij, a joint venture on a parity basis between Royal Dutch / Shell and ExxonMobil .
