The Influence of Slope on Turbidity Currents and Their Deposits in a Process-Based Model

Turbidity currents transport land-derived sediment to deep sea where theirdeposits form large geological structures termed submarine fans. Giventheir large areal extent and high sand content, submarine-fan deposits formsignificant hydrocarbon reservoirs. Their internal architecture is often poorlyresolved. With much of the three-dimensional...

A Classification of Clay-Rich Subaqueous Density Flow Structures

This study presents a classification for subaqueous clay-laden sediment gravity flows. A series of laboratory flume experiments were performed using 9%, 15%, and 21% sediment mixture concentrations composed of sand, silt, clay, and tap water, on varying bed slopes of 6°, 8°, and 9.5°, and with discharge rates of 10 and 15 m³/hr. In...

Upscaling polymer flooding: Developing a workflow based on particle swarm optimization

In this research a workflow for upscaling polymer flooding is developed. The workflow generates pseudorelative permeabilities (pseudos) to represent flow behaviour affected by fine scale heterogeneities in a coarse grid. With this workflow, a better estimate of the difference in production from a polymer flood compared to a water flood can be...

Turbid Flows and Their Deposits on Slopes with Minibasins: A Modelling Approach

Passive continental margins display a great diversity of seafloor bathymetries induced by gravity driven extensional faulting and compressional folding, as well as diapiric movements of salt or mud. In many diapirically controlled settings, slope bathymetries are complicated and characterized by numerous ridges, trenches and minibasins such as...

3D Geological Models of Submarine Lobes from Borehole Data, Permian Tanqua-Karoo Basin, South Africa

The Permian Skoorsteenberg Formation in the Tanqua-Karoo basin in South Africa provides excellent exposure of submarine basin-floor fans. Because of this, the European Union sponsored various outcrop studies, drilling as well as the data acquisition of the research boreholes in the NOMAD project. It was a unique opportunity to study a submarine...

Borehole Images and Logs: Tools to Constrain the Architecture of a Channelized Slope System, Karoo Basin, South Africa

The SLOPE3 project investigates the depositional architecture of a Permian age, deep water / complex channelized slope system which is of interest to the oil industry as a potential analogue for real oil / gas reservoirs. This study forms a part of the SLOPE3 project and is focused on an integration of cores and wireline logs from six research...
