Development of a Modelling Framework for Core Data Integration using XRF Scanning

Sedimentary deposits are important archives of the Earth’s history. In addition, they are of key economical and societal importance because they contain natural resources (e.g., hydrocarbons and drinking water). Hence, it is of utmost importance that we understand the mechanisms controlling the heterogeneity, morphology and spatial distribution...

Analysis of Natural Fractures in the Basal Zechstein Carbonates in the Dutch Offshore Area using Wireline Log Data

The primary gas reservoirs in the Southern Dutch offshore are in decline. Discoveries of new gas reservoirs are getting smaller and smaller reservoirs receive more attention. The three major carbonate beds in the Basal Zechstein (Z1C, Z2C and Z3C) are considered potential secondary gas reservoirs. To be able to develop the gas from these...

Basin settings of the Upper Jurassic Source Rock of the Southern Danish Central Graben

From 3D seismic interpretation and well logs five of the strongest reflectors of the Upper Jurassic Source Rock along the Southern DGC were mapped, the markers were correlated with biostratigraphic and geochemical data. It was generated a simple 3D basin model. The Southern DCG experienced a strong subsidence during Kimmeridgian with tilted...

The Sensitivity of the 3D Connectivity in a Multi-Scale Fracture Network to Variations in Distribution Parameters: A Case Study from Petra, Jordan

The behavior of naturally fractured reservoirs is very different from that of conventional reservoirs. In order to develop a successful production strategy it is important to understand this behavior. Golder Associates developed a software package to model heterogeneous and fractured rock masses. FracMan generates three-dimensional fracture...

Reservoir stratigraphy and architecture of glacial tunnel valleys reservoirs: Examples from Ordovician of North Africa and Pleistocene of North America

Upper Ordovician glaciogenic rocks from Block-NC186, in the Murzuq Basin, SW Libya, represent important hydrocarbon reservoirs. The producing reservoirs are found in glacial incisions filled by the Melaz Shuqran and Mamuniyat formations. These formations present complex reservoir architecture and high sediment heterogeneity. Understanding the...

3D Modeling of a foreland fold and thrust basin in the French sub-Alpine chains

In this report, one can find a summary of the results and the methods used in a BSc-thesis, with as aim to unravel the structural geological situation of a 54 km2 area in the southern French sub-Alps around the village of Plaisians. This was done by using the Move© software-package, provided by Midland Valley. The work was performed in several...

Identification of Ferromagnetic Minerals: Magnetic mineral analysis of Pannonian, Sarmatian and Badenian (10.5-13.7 MA) sediments from the spannberg 21 well (Ebenthal, Austria)

The magnetic mineral content of marine and fluviatile sediments in the Vienna Basin, Austria has been measured and described. The magnetic signal measured in a well records the earth’s magnetic field during deposition of the sediments. Two main ferromagnetic minerals, magnetite and greigite, are found as the dominant natural remanent magnetism...

A core study to determine the heterogeneities in the Delft Sandstone Member in the Moerkapelle Field

A homogeneous dynamic reservoir model has been build for the Delft Sandstone Member, but geological formations are never completely homogeneous. The objective of this study is to increase knowledge about the heterogeneity of the Delft Sandstone Member for the construction of a future heterogeneous dynamic reservoir model of the Delft Sandstone...

Comparing different shallow geophysical methods in a tidal estuary, Verdronken Land van Saeftinge, Western Scheldt, the Netherlands

In order to validate existing models of sedimentation in active sedimentary environments, detailed stratigraphic information is indispensable. Near-surface geophysical methods provide a means to acquire high-resolution images of the stratigraphic succession in the shallow subsurface. Land-based and marine methods have been tested in the...

Modeling suspended sediment discharge from the Waipaoa River system, New Zealand: The last 3000 years

HydroTrend, a hydrologic-transport model, is used to simulate the water and suspended sediment discharge of the Waipaoa River system over the last 3 Kyr, a time period in which a well-documented sequence of natural events and anthropogenic activities that profoundly impacted drainage basin processes occurred. Comparisons between observed and...
