A method, comprising receiving input data representing a subterranean formation, defining a grid representing the input data, with the grid including cells. The method also includes identifying at least one of the cells in which kerogen is present based on the input data, simulating hydrocarbon movement within the kerogen using the grid, and generating a model of hydrocarbon expulsion to pore space based on the simulating.

Modeling diffusion and expulsion of hydrocarbons in kerogen

A method, apparatus, and program product model address a modeling gap existing between basin and reservoir modeling through the use of a Reservoir Fluid Geodynamics (RFG) model usable for simulations conducted at a relatively fine spatial resolution and over a geological timescale.

Modeling of oil and gas fields for appraisal and early development

A method, apparatus, and program product utilize a multi-step subsidence inversion to model lithospheric layer thickness through geological time for a rift basin in a subsurface formation.

Multi-step subsidence inversion for modeling lithospheric layer thickness through geological time

A method for performing a field operation within a geologic basin having rock formations and a reservoir that includes fluids includes generating, by forward modeling using a petroleum system model (PSM), an estimate of a fluid property distribution of a fluid within the reservoir of the geologic basin. The method further includes detecting, from fluid samples, a fluid property gradient within the geologic basin. The fluid samples are extracted from within at least one wellbore drilled through the rock formations. The method further includes, comparing the estimate of the fluid property distribution with the detected fluid property gradient to generate a comparison result, iteratively adjusting, based on the comparison result, the PSM to generate an adjusted PSM, and performing, based on the adjusted PSM, the field operation within the geologic basin.

Combining downhole fluid analysis and petroleum systems modeling

Prospect assessment and play chance mapping tools are provided. For assessing potential resources, example systems provide dynamically linked chance maps, transformed in real time from geological properties. Input geological maps or other data are dynamically linked to resulting chance maps, so that changes in the input maps automatically update the chance map in real time. Users can generate a custom risk matrix dynamically linking geological maps with chance maps via interface tools, dropping maps directly into the matrix. A transform may programmatically convert the geologic domain to the chance domain. The user can navigate input maps, select areas of interest, and drag-and-drop geologic properties into an uncertainty engine and distribution builder for uncertainty assessment based on geologic reality. A merge tool can programmatically unify multiple geological interpretations of a prospect. The merge tool outputs a single chance of success value for multiple geologic property values at each grid node.

Prospect assessment and play chance mapping tools

The invention provides a system and method for integrating petroleum system and geomechanical computer models for use in oil and gas exploration. In one embodiment, the invention provides a petroleum system model capable of analyzing data relating to a subterranean formation and calculating the geometry and geochemistry of each layer of the formation through geologic time. The present invention also provides a geomechanical model in communication with the petroleum system model such that information concerning each layer of the subterranean formation may be shared and cross-referenced as an iterative operation prior to the analysis of subsequent layers. At each step of the iterative operation, results are calculated, validated, and cross-referenced in order to produce improved reliability estimates of petroleum charge and mechanical seal integrity for the subterranean formation.
