NAM: onwaarschijnlijk dat productiecapaciteit Groningerveld op peil blijft
DATA - De Provincie Groningen heeft op 11 juli haar advies op het instemmingsbesluit 2018 voor het Groninger gasveld aan Provinciale Staten gezonden (agendapunt 3.2.c). In de vele bijlagen zit op bladzijde 27 van bijlage 2 (pdf) een interessante passage met betrekking tot de productiecapaciteit:
Figure 3-5 compares the production to the available capacity in each region (under the unlikely assumption that all clusters remain available). The downward spikes in the region capacities are related to planned shutdowns of production clusters for maintenance and inspections, while the seasonal fluctuation in capacity is a reflection of the fact that the ambient temperature influences the efficiencies of the coolers and hence the total compressor efficiency. Another observation that can be made is that the production capacity is relatively constant through time for most regions. The South-East region shows a notable decline in capacity until 2022, after which the decline is halted and eventually capacity starts to increase again. This behaviour is a function of the reservoir pressure in the direct vicinity of the production clusters within each region. A declining reservoir pressure yields a declining production capacity, whereas an increasing reservoir pressure yields an increase in production capacity.
