Petrel structural and fault analysis

Analysis of fault sealing capabilities and mapping QC tools

Overview

The Petrel™ structural and fault analysis module allows for more accurate mapping of faults, rapid definition of critical flowing or sealing windows along the faults, better integration of fault properties and geometries within the simulator, and the ability to easily tune fault data to observed core or dynamic data.

The potential flow indicator allows visualisation of the bulk permeability defined from the host and fault rock.

Displacement calculated for structural framework faults.

Allan diagrams showing zonal juxtapositions help highlight key reservoir connections.

Any seismic attribute can be extracted onto structural framework faults, helping interpretation tasks around these faulted areas.

Well juxtaposition analysis allows for rapid understanding of seal potential at the exploration stage, without creating a 3D grid.

Confidence map showing surface stability of the interpretation together with strength of amplitudes on and around the pick.

Prediction of the fault throw from a seismic horizon and fault stick interpretation.

Applications

Allan diagrams showing zonal juxtapositions help highlight key reservoir connections.
Well juxtaposition analysis allows for rapid understanding of seal potential at the exploration stage, without creating a 3D grid.
Defining discrete breaks in the interpretation in order to produce a high resolution image of the fault network.

Benefits

The module allows geoscientists to perform fault seal analysis faster, more simply, and with greater accuracy and repeatability. The module also provides front-line fault juxtaposition and property mapping tools for exploration and production environments. Fault transmissibility multipliers can be calculated, analyzed, and modified to provide critical input into accurate flow simulation models.

Features

Efficient data cleanup and modeling tools improving the ease and accuracy of seismic interpretation and structural modeling within the Petrel platform
Identification and mapping of critical fault juxtaposition, high-flow zones, or seal continuity areas
Capability to perform numerous up-to-date or core-calibrated fault seal predictions in real time or automatically within the workflow to allow calibration and reduce uncertainty
Comprehensive scenario analysis tools to illuminate structural and fault seal uncertainties
Potential flow indicators providing a powerful means of screening the impact of these parameters on fluid flow
Tuning of faults to dynamic data by applying numerous methods to modify transmissibility—either globally per fault or locally along specific sections of faults—to rapidly achieve accurate history matches
