Approach to evaluate the probability to encounter high amounts of non-hydrocarbons in reservoirs: Dutch CO2 case studies

Non-hydrocarbons (H2S, CO2, N2) reduce the economic value of natural gas accumulations. This paper presents new approaches to evaluate the probability to encounter high amounts of non-hydrocarbons. These approaches were developed as one of the deliverables of a 2-year JIP project carried out by TNO from September 2014-July 2016. The newly...

Fault reactivation mechanisms and dynamic rupture modelling of depletion-induced seismic events in a Rotliegend gas reservoir

Understanding the mechanisms and key parameters controlling depletion-induced seismicity is key for seismic hazard analyses and the design of mitigation measures. In this paper a methodology is presented to model in 2D the static stress development on faults offsetting depleting reservoir compartments, reactivation of the fault, nucleation of...

Lateglacial and early Holocene vegetation development and fluvial system changes in the northern Meuse valley, the Netherlands: a review of palynological data

This study provides an overview of existing palynological and chronological data of the northern Meuse valley which have been collected over recent decades. The palynological data were used to make a vegetation reconstruction in time and space for the Lateglacial and early Holocene. The vegetation development is strongly influenced by the rapid...
