Abstract
Production induced subsidence and seismicity in the Groningen gas field – can it be managed?
Highlights
By end 2013 production induced subsidence above the centre of the Groningen gas field in the Netherlands amounted to some 33 cm with subsidence increasing at a rate of some 7–8 mm per year
As reported for a number of other oil and gas fields (Lee, 1979; Merle et al, 1976; de Waal and Smits, 1986; Hettema et al, 2002; Mallman and Zoback, 2007; Kosloff and Scott, 1980) subsidence rate in Groningen was initially significantly lower than predicted on the basis of laboratory rock-mechanical measurements carried out on samples taken from the reservoir
Already during the early stages of field development it was realised that the gas production from the Groningen field could lead to a significant amount of surface subsidence
Summary
By end 2013 production induced subsidence above the centre of the Groningen gas field in the Netherlands amounted to some 33 cm with subsidence increasing at a rate of some 7–8 mm per year (van Thienen-Visser and Breunese, 2015a; Pijpers, 2014a). Such an amount of subsidence requires the design and implementation of proper mitigation measures in a near sea-level country like the Netherlands (de Waal et al, 2012). Thereafter the recent developments will be discussed that followed the 2012 insight that risks from reservoir compaction induced seismicity in Groningen might be significantly higher previously realised (MuntendamBos and de Waal, 2013)
