Several faults in the border area between Netherlands and Germany show a complex structure. Deep seismic lines do not reveal the shallow structure well enough and the density of the available lines is low. We conducted two high resolution seismic reflection lines to clarify some of the geological questions about the fault structure. This paper...

A potential solution to mitigate the adverse effects of viscous fingering, gravity override, and reservoir heterogeneity on the efficiency of gas injection in porous media is to inject the gas with a solution containing surface-active agents such as surfactants or nanoparticles. The efficiency of these processes largely depends on the generation...

Accurate characterization and reliable monitoring of geological reservoirs often requires extensive geophysical measurements, in particular time-lapse (4D) seismic surveys. The conventional approach to reveal the time-lapse changes is to perform comprehensive seismic surveys with high repeatability. This approach is often not economically viable...

Since 2004 the feasibility of CO2 injection and storage in depleted natural gas fields has been researched and demonstrated at K12-B, a gas field on the Dutch continental shelf. In total over 100 Kton of CO2 was injected. The entire operation at the K12-B field was completed without any major complications. It can therefore be stated that safe...

The mission of ECCSEL ERIC is to establish a world class, distributed, pan-European CCS Research Laboratory Infrastructure to enable the removal of research barriers and facilitate wide scale deployment of CO2 capture, transport and geological storage in Europe. We present the rationale and development of ECCSEL ERIC, and consider ECCSEL in...

Timing errors are a notorious problem in seismic data acquisition and processing. A technique is presented that allows such time shifts to be detected and corrected in a systematic fashion. The methodology relies on virtual-source responses retrieved through the application of seismic interferometry (SI). In application to recordings of ambient...

To manage risks in CO2 storage operations, monitoring systems need to be designed such that the data can inform the operator whether the storage site will continue to behave as expected or not. In order to compare the benefits of different monitoring strategies, we require a measure of ‘efficiency' that is based on a balance between monitoring...

We investigate the potential for improved recovery of subsurface energy resources (hydrocarbons or heat) through in-depth diversion technology. A number of pilot studies in the North Sea have demonstrated in recent years that sodium silicate can be used to block preferential flow paths and divert water to previously unswept areas of a reservoir....

Regional velocity models are used mainly for time-to-depth conversion. At regional scales, where few horizons are available, the accuracy and consistency of the velocity models relies on the integration of seismic velocities which bring additional information in terms of lateral and vertical heterogeneities. Such heterogeneities can only be...

A modelling approach is described in which time-domain underwater-acoustic source functions are generated using a model that predicts the motion of air-bubbles generated by mini-airguns operated at various pressures. These time-series are Fourier-transformed to produce frequency-domain descriptions of the source. These are combined with complex...

Since the early 2000's there has been a significant focus from many groups around the world towards the development and application of innovative technologies in order to improve reservoir management strategies and optimize field development plans. Benchmark studies are a very valuable way of evaluating and demonstrating the status and potential...

In the context of carbon capture and storage (CCS), quantitative estimation of injected CO2 is of vital importance to verify if the process occurs without any leakage. From a geophysical perspective this is challenging as a CO2 plume has a severe imprint on seismic data. While this makes delineation of the plume rather straightforward, for...

CO2 storage needs economic business cases through cost-effective exploration and production and needs license-to-operate through public support. Re-interpretation and reprocessing of vintage geophysical data is a means to achieve cost-effective exploration whereas de-risking and conformance control of storage operations is a means to obtain...

Alternating injection of water and gas (WAG) has been widely applied as an oil recovery strategy since the late 1950s. The expected benefits are improved macroscopic sweep, with the water and gas sweeping lower and upper zones of the reservoir respectively, and improved microscopic sweep due to various effects leading to lowering of the residual...

A distance parameterization of flood fronts derived from time-lapse seismic anomalies was recently developed to facilitate incorporation of time-lapse seismic data into history matching workflows based on ensemble methods such as the ensemble Kalman filter (EnKF) and the ensemble smoother (ES). A number of advantages were demonstrated on...

Recent progress in 4D seismic history matching benefits greatly from the use of 4D seismic timelapse data. Several methods for inversion of 4D seismic timelapse data for reservoir pressure and saturation have been developed with mixed success. Most of these methods work well on synthetic data or real data with low noise levels, but degrade in...

This paper discusses the influence of hydraulic continuity of reservoirs and faults and the lack thereof on the occurrence of local pore fluid pressure conditions deviating from previously established regional trends. The hydrodynamic-based approaches will be illustrated with case studies from the Netherlands, in particular.

Over the last decade, various international and national assessments of shale gas and shale oil resources for most EU-countries have been published. Due to methodological differences and in fundamental assumptions related to the quality and quantity of underlying geological information, these results are not comparable and in some cases not...
