In gas wells, decreased/unstable production can occur due to difficult-to-predict dynamic effects resulted from late-life phenomena, such as liquid loading and flooding. To minimize the negative impact of these effects, maximize production and extend the wells’ lifetime, wells are often operated in an intermittent production regime. The goal of...

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...

Operating maturing assets poses increasingly complex challenges to operators. Meeting hourly or daily production targets becomes more difficult when wells are more often shut in for e.g. water washes (against salt deposition) or solvent jobs (at asphaltenes deposition). Declining reservoir pressure in turn results in less margin to compensate...

Statoil is implementing "Fast Model Update (FMU)," an integrated and automated workflow for reservoir modeling and characterization. FMU connects all steps and disciplines from seismic depth conversion to prediction and reservoir management taking into account relevant reservoir uncertainty. FMU delivers an ensemble of geologically-consistent...

We consider robust ensemble-based (EnOpt) multi-objective production optimization of on-off inflow control devices (ICDs) for a sector model inspired on a real-field case. The use of on-off valves as optimization variables leads to a discrete control problem. We propose a re-parameterization of such discrete controls in terms of switching times,...

With an increase in the number of applications of ensemble optimization (EnOpt) for production optimization, the theoretical understanding of the gradient quality has received little attention. An important factor that influences the quality of the gradient estimate is the number of samples. In this study we use principles from statistical...

In order to be able to predict the distribution of reservoir sands and of grainsize and porosity trends in a hydrocarbon province, it is essential to understand the basin evolution in detail. In this study, an attempt is made to reconstruct the complex basin evolution of the southern Central Graben area by careful correlation of sedimentary...

Shale gas reservoir stimulation procedures (e.g. hydraulic fracturing) require upfront prediction and planning that should be supported by a comprehensive reservoir characterization. Therefore, understanding shale depositional processes and associated vertical and lateral sedimentological variability is key in predicting the character and...

In 2011, TNO-GDN concluded a 5 year geological mapping of the Netherlands Continental Shelf. In this project all public data from hydrocarbon exploration were used resulting in a major update of the dataset and a variety of deliverables available at www.NLOG.NL. The stratigraphy of more than 400 wells has been re-examined and amended where...

Various Dutch operators have identified a need for increased application of deliquification measures in their North Sea wells. To help meet this need a Joint Industry Project (JIP) was set up to identify knowledge and experience gained in the United States on gas well deliquification and transfer this to European wells. In the first phase of the...

Recent exploration and production activities in the Cenozoic Southern North Sea (SNS) deltas, proved the economic potential of shallow gas resources, especially if located near existing infrastructures. Nonetheless, shallow gas production is still limited due to a lack of insight in the petroleum system, especially with respect to the relation...

The subsurface of the onshore and offshore Netherlands has been studied extensively. In 2006 the first complete maps of the main stratigraphic horizons (down to the Permian) were published. Since then these maps were regularly updated and extended to include also the main reservoir horizons. This detailed stratigraphic information was used to...

TNO Geological Survey of the Netherlands systematically produces 3D voxel models for answering subsurface related questions. The unique combination of vast amounts of borehole data and the voxelbased approach makes the models valuable new sources for exploring the Quaternary fluvial record. The latest generation of 3D voxel models (GeoTOP)...

The Dutch Koekoekspolder geothermal doublet was drilled in 2011 targeting the Permian Rotliegendreservoir. The encountered reservoir properties were less favorable than expected pre-drill. Post-drill integrated evaluation of vintage data and the new data from the geothermal wells resulted in a refined depositional model of the area. The...

We investigated the impact of the exploitation of a geothermal well doublet on surface movement. We found that the largest effect should be expected from the progressive cooling of the reservoir, through the thermo-elastic coupling. The absolute value of the expected subsidence is low, but possibly measureable if circumstances are favourite. In...

As gas and oil fields mature their operation becomes increasingly more complex, due to complex process dynamics, like slugging, gas coning, water breakthrough, salt or hydrate deposition. Moreover these phenomena also lead to production constraints in the upstream facilities. This complexity asks for operator support in how to optimally operate...

Since July 2008 CO<inf>2</inf> is injected into a saline aquifer near Ketzin, in Germany. The reservoir used for CO<inf>2</inf> injection is the Stuttgart Formation of Triassic age, located at a depth of about 650 m. Close to the injection well, TNO designed and implemented a permanent shallow seismic monitoring system. The system consists of 3C...

We describe a water dispersed nano sensor cocktail based on InP/ZnS quantum dots (QDs) and atomic silver clusters with a bright and visible luminescence combined with optimized sensor functionalities for the water flooding process. The QDs and Ag nano sensors were tested in simulated reservoir conditions (high salinity, Ca2+, pH, high...

A history matching workflow, as typically used for updating of petrophysical reservoir model properties, is modified to include structural parameters including the top reservoir and several fault properties: position, slope, throw and transmissibility. A simple 2D synthetic oil reservoir produced by waterflooding is used to demonstrate issues...

In this paper we present laboratory experiments where we address the Ground Penetrating Radar (GPR) capability of monitoring oil displacement processes in porous media. This has significant applications in near-subsurface environments where remediation of contaminant such as oil-derived liquids is considered one of the major technical,...
