Hydrocarbon migration systems analysis

At a certain time during the evolution of a sedimentary basin the secondary separate phase hydrocarbon migration is driven by hydrocarbon potential gradients (Equation 4.11 Sections 4.1.1 and 5.2), which in turn are controlled by [Pg.197]

Magnitude and direction of the capillary pressure gradient (grad p ) [Pg.198]

The actual rate of secondary hydrocarbon migration is controlled by the [Pg.198]

On a basin-wide scale, the pattern of secondary migration of separate phase hydrocarbons in a sedimentary basin at a certain time during its evolution is thus determined by [Pg.198]

The main types of raw data used in the analysis of secondary hydrocarbon migration systems for basin evaluation are those relating to present and past physico-chemical characteristics of groundwater (groundwater pressures, temperatures, salinities, chemical compositions) and porosities and permeabilities of the subsurface. In addition, information on the physicochemical characteristics of source rocks and of hydrocarbon acciuuulations is necessary to complete the quantitative assessment of hydrocarbon migration systems. [Pg.201]

In the analysis of groundwater flow systems and hydrocarbon migration systems, the measured temperature data are used to calculate heat flows and geothermal gradients. In a sedimentary basin, within which the transport of heat is largely by conduction and where refraction of heat flow is unimportant, the heat flow is constant with depth (e.g. Andrews-Speed, et al., 1984) and is given by... [Pg.206]

QUALITATIVE ANALYSIS OF SECONDARY HYDROCARBON MIGRATION SYSTEMS... [Pg.211]

In the qualitative analysis of hydrocarbon migration systems, attention is focussed on the identification of present and past basin-wide or regional patterns of secondary hydrocarbon migration. In a sequence of steps, a set of maps is prepared, which in combination will qualitatively show the potential patterns of secondary hydrocarbon migration at a certain time during the evolution of a sedimentary basin. [Pg.211]

A quantitative analysis of present-day secondary hydrocarbon migration for basin evaluation can be restricted to the prospective parts of a sedimentaiy basin as selected on the basis of the previously described qualitative study (Chapter 7). The quantitative assessment of present-day hydrocarbon migration systems is described separately for hydrostatic and hydrodynamic conditions of the prospective parts of the basin (Sections 8.1, 8.2 and 8.3). Section 8.4 briefly describes the available approaches for a quantitative analysis of the evolution of secondary hydrocarbon migration systems. [Pg.227]
