What's new in Move2017.2

Elliptical Fault Flow: a brand new 2D kinematic algorithm. The algorithm has been developed by Midland Valley and models the deformation associated with isolated normal faults that exhibit decreases in fault displacements in all directions, away from the point of maximum offset. The release also contains many updated features and performance improvements throughout Move and the advanced modules.

Move - the core application

Move Knowledge Base

Beginning with Move2017, we are introducing the first release of the Move Knowledge Base. The Knowledge Base resource contains all the Move Help Pages, Tutorials, and the release documentation presented in a single, offline, searchable entity, independent of Move. The material is partially cross-referenced and brings together for the first time, tutorial workflows that are referenced from help pages; and help pages and theory material that are now linked from tutorials. We plan to take this new resource forward with greater cross-referencing, plus the addition of case studies, course material, and video teaching materials. Additionally, we would like to make Move Knowledge Base updateable throughout the year as we change and improve our teaching material.

Fault Analysis

Complemented by the new features, Fault Analysis in Move2017 allows rapid temporal evaluation of throw distribution, across-fault juxtaposition and fault sealing capacity. Combined with statistical analysis of fault displacement and scaling relationships, the tool provides robust validation of geological interpretations and insight into the economic significance of faults.

Further Developments (NEW in Move2017.1)

  • A Fault History diagram has been added to allow rapid evaluation of fault throw and seal distributions through time.
  • Restoration results can be used to create more accurate temporal Throw Profiles and Fault Growth plots.
  • Three new methods have been added to interrogate fault sealing properties: Probabilistic Shale Smear Factor, Hydrocarbon Column Height and Permeability.
  • Create filtered seal and juxtaposition colour maps and compose multi-layered visualizations.
  • Surface areas of specific proxy or juxtaposition values can be estimated using the Area.
  • Analysis tool.
  • Individually define trim and inclusion distances per side of each fault and highlight included data points.
  • Import custom length/throw data into the Fault Scaling chart to compare analysed faults to previously measured length/throw relationships.
  • Multiple well projection: Define and project unique hanging wall and footwall well logs.
  • Juxtaposition Triangles with hanging wall growth: Plot juxtaposition triangles from a single well with the ability to test multiple hanging-wall growth scenarios.

Fault Analysis

Fault Response Modelling

Move2016 saw the launch of the Fault Response Modelling module in Move. This module is a highly versatile tool that can be used to validate an interpretation, identify highly fractured zones and realistically model stress perturbations around faults and other discontinuities. This module has been updated with new features for Move2017.

Further Developments (NEW in Move2017.1)

  • Fracture sets can be used as Master Faults, which allows the interaction between fracture planes and the transfer of strain in DFNs (Discrete Fracture Networks) to be modelled.
  • Slip Zone Modelling (Jeyakumaran 1992) is now available for Master Faults. This allows modelling of realistic slip gradients and strain transfer between faults based on a defined traction, a regional or driving stress.
  • A new 'Displacement on Master Fault' tab can be used to colour map the Master Faults for different slip parameters.
  • Adding the Master Fault as an Observation Object allows the positive (hanging wall) and negative (footwall) displacement to be calculated and colour mapped via the new ‘Displacement on Master Fault’ tab.
  • The new 'Fracture Analysis: Angular Misfit' sheet allows the user to calculate the angular misfit between observed fractures and fractures modelled using Fault Response Modelling, or calculated using Strain Capture from Geomechanical or 3D Kinematic Modelling.
  • In the Options sheet, the user can specify whether to use infinitesimal strain or finite strain. The triangular dislocation theory used in Fault Response Modelling is based on infinitesimal strain therefore this is the default option. The finite strain option is relevant when using strain captured from 3D Kinematic or Geomechanical Modelling for fracture analysis in the Fault Response Modelling module.
  • The 'Fracture Analysis: Angular Misfit' can also be used to search for the best fitting slip direction on faults by minimising the angular misfit to observed fractures from multiple simulation runs.
  • Plunge and plunge azimuth of displacement vectors are saved on Master Faults when the displacement is defined using Max Shear Direction, Remote Loading or Traction. These can be then be visualized, for example, as Lineation data in the Stereonet plot.

Stress Analysis

Further Developments (NEW in Move2017.1)

  • Max shear direction is now showing the sense of slip.
  • Lineation data can now be displayed with a sense of slip.
  • Lineation data can now be displayed with a tangential slip representation (tangent lineation / Hoeppner plot). The slip vector can be set to represent either hanging wall or footwall movement.
  • Lineation data can now be projected onto slip planes.
  • The sense of slip is now fully integrated into stress inversion.
  • Seismic Moment Tensor Decomposition is now available in Stress Analysis. The user can choose between a shear and tensile source model.
  • When analysing fractures in the Stress Analysis module, the specific orientation data that meet a failure criterion are shown as filtered points or as a filtered fractures in the view. All Stress Overlays with appropriate tolerance can be used for this filtering method. In addition, the filtered information can be created as an object for further usage in projects.The palaeo-stress state can be determined from striation data within the Lineation / Stress Inversion sheet. The method used for determining the stress state is from Angelier (1990).
