GPM Clastics

Predict the deposition, composition, and geometry of clastic sediments

Overview

GPM™ geological process modeling software is used to build advanced digital geological models predicting clastic sedimentary stratigraphic sequences.

Users have access to the fundamental physical controls of sedimentation including diffusion and both steady-state (for example, fluvial and deltas) and unsteady-state (for example, floods and turbidites) flow as well as other controlling parameters such as compaction, tectonics, sea-level fluctuation, and wave action. Additionally, users have access to processes for modeling sediment accumulation with several output properties for quality control of the result.

GPM 2D allows to test, validate and capture the geological scenarios that will best describe the study area in 2D while considering the physical processes controlling them. 2D forward model of the sediment distribution in a prograding delta system tract with boundary conditions calibrated with the seismic (Netherlands Offshore F3 Block dataset used with permission of dGB Earth Science)

2D geological process-based modeling is used to interactively evaluate and better understand the impact of parameter selection on the stratigraphic responses as well as capture the effect of different sea-level fluctuations on the resulting sedimentation patterns. 2D forward model of the Vail et al.

2D geological process-based modeling is used to validate the geological concepts, refine the initial boundary conditions and build robust geological understandings and scenario appraisals thereby allowing to then confidently evolve to 3D complex modeling. 2D forward model in a prograding delta system tract (Netherlands Offshore F3 Block dataset used with permission of dGB Earth Science)

Geological process-based modeling uses realistic geological trend information in a quantitative manner. The resulting digital representation of the geology enables to not only predict the lithology distribution and petrophysical properties but can also be used to synthetically create the associated seismic response, providing insights below the resolution of measurements. 2D forward model of the Vail et al.

Wheeler diagrams can be created from geological process-based models thereby providing snapshots of geologic times and allowing the study of sediment distribution and basin-fill architecture in relation with changes in sea-level and accommodation space. 2D forward model of the sedimentary infill in a prograding delta system tract (Netherlands Offshore F3 Block dataset used with permission of dGB Earth Science)

GPM 2D is based on a user-defined or hand-drawn cross-section and leverages on the Petrel platform visualization capabilities to seamlessly draw geological insights and capture the effect of different basin subsidence and uplift on the final basin topography. 2D forward model of the sedimentary infill in a prograding delta system tract with boundary conditions calibrated with the seismic interpretation (Netherlands Offshore F3 Block dataset used with permission of dGB Earth Science).

Applications

The GPM Clastics module enables simulating the main processes controlling the erosion, transportation, and deposition of clastics sediments from source to sink.

Benefits

All available processes can be modeled independently or concurrently. The processes are modeled deterministically through the numerical simulation of physical processes.

In addition to modeling clastics, users can model clastics and carbonates together.

Features

GPM software is tightly integrated with other SLB technologies to enable addressing challenges at different scales—from basin to reservoir—with applicability throughout the entire E&P lifecycle, from early exploration to improved oil recovery (IOR). It works with the Petrel subsurface software enabling for seamless conversion of the GPM software results into Petrel surfaces and 3D models for use in subsequent workflows (for example, direct conditioning of geostatistical modeling, direct inputs for Depospace or seismic forward modeling workflows...to increase reservoir predictability).

It can also be connected to PetroMod petroleum systems modeling software for basin-scale studies to support the subsequent analysis of the petroleum systems by understanding the charge migration and accumulation of potential hydrocarbons, which is critical for exploration success. Finally, GPM software results can also be used as input in gross depositional environment (GDE) maps, the Play and Prospect Assessment workflow for the Petrel software, and Geox exploration risk, resource, and value assessment software to refine the final reservoir understanding and explore economic scenarios toward reaching more confident decisions.
