Understanding the stratigraphic fill and reconstructing the palaeo-hydrology of incised valleys can help to constrain those factors that controlled their origin, evolution and regional significance. This condition is addressed through the analysis of a large (up to 18 km wide by 80 m deep) and exceptionally well-imaged Late Pleistocene incised valley from the Sunda Shelf (South China Sea) based on shallow three-dimensional seismic data from a large (11 500 km2), ‘merge’ survey, supplemented with site survey data (boreholes and seismic).

This approach has enabled the characterization of the planform geometry, cross-sectional area and internal stratigraphic architecture, which together allow reconstruction of the palaeo-hydrology. The valley-fill displays five notable stratigraphic features: (i) it is considerably larger than other seismically resolvable channel forms and can be traced for at least 180 km along its length; (ii) it is located in the axial part of the Malay Basin; (iii) the youngest part of the valley-fill is dominated by a large (600 m wide and 23 m deep), high-sinuosity channel, with well-developed lateral accretion surfaces; (iv) the immediately adjacent interfluves contain much smaller, dendritic channel systems, which resemble tributaries that drained into the larger incised valley system; and (v) a 16 m thick, shell-bearing, Holocene clay caps the valley-fill. The dimension, basin location and palaeohydrology of this incised valley leads to the conclusion that it represents the trunk river, which flowed along the length of the Malay Basin; it connected the Gulf of Thailand in the north with the South China Sea in the south-east. The length of the river system (>1200 km long) enables examination of the upstream to downstream controls on the evolution of the incised valley, including sea-level, climate and tectonics. The valley size, orientation and palaeohydrology suggest close interaction between the regional tectonic framework, low-angle shelf physiography and a humid-tropical climatic setting.

The presentation will be concluded by considering how some of these concepts might be applied to other fluvial systems in SE Asia, including those that form petroleum reservoirs.

Reservoir quality is the main attribute that controls well productivity and field-wide performance. Yet, even though oil companies have invested significantly in techniques to understand and predict reservoir quality, it still remains a significant challenge and source of investment risk for the industry.

The search for unconventional hydrocarbons is not new. It’s true that almost 100 years separated the early exploration successes in the synclinal valleys of Central Pennsylvania, to the exploitation of Coal-Bed Methane in a number of basins in the U.S. and Canada in the 1980’s. Since the 1980's, however, a quiet revolution began which by today has seen several waves of unconventional resources being pursued with economic success. Coal-bed methane was followed by the search for Center-Basin Gas, Shale Gas and most recently, Liquid-rich Shales (some of which aren't shales).

Sequence stratigraphy provides a framework for the integration of geological, geophysical, biostratigraphic and engineering data, with the aim of predicting the distribution of reservoir, source rock and seal lithologies. It gives the geoscientist a powerful predictive tool for regional basin analysis, shelf-to-basin correlation, and characterization of reservoir heterogeneity. This course will examine the underlying geological principles, processes and terminology related to sequence stratigraphic interpretation. The strength of this course is the application of these basic principles to subsurface datasets in a series of well-founded exercises.

Water cut is a big factor in gauging the success of horizontal drilling in the Mississippi Lime Play (MLP). The contributing factors are related in part to the spectrum of producing lithofacies and reservoir quality encountered that varies laterally and vertically, sometimes dramatically.
