Welcome to the Intrepid Geophysics’ summer/winter sols�ce newsle�er of December 2017. We hope you are well,and reflec�ng on a prosperous year, almost behind us. (Don’t be too jealous of Santa in the sunshine Downunder,we’ll have the flip-side in June!)
Items in this Newsle�er:

Ahead:
Next conferences: AEGC Sydney & PDAC Toronto
Next Workshop: 4th mee�ng of the European 3D GeoModelling Community
European Training for GeoModeller V4 & FEFLOW interoperability
SoGware training will be held at BRGM in Orléans, France on Monday and Tuesday, 19th and 20th February, justprior to the 3D GeoModelling Community workshop. This two-day training course will feature a new maintenancerelease of GeoModeller v4.0.1, provided with add-on CGAL libraries for tetrahedron meshing.
Introductory model-building and forward geophysical modelling will be covered, plus extension exercises for addingand controlling limited faults and thin bodies. Day 2 (Feb 20) will focus on GeoModeller model-exports for flowsimula�on using FEFLOW, including the now-available “Smart Layering” and “Fully unstructured” meshing op�ons.DHI-WASY will co-present the training on model transfer steps, and set-up for performing a simple flow simula�onproblem in FEFLOW.

Improvements for GeoModeller-MOKSHATM
In-house product: GeoModeller-MOKSHATM con�nues to be improved with new features to be�er serve our clients
summer/wintersolsticenewsletter
reques�ng line-kilometre 2.5D inversions of their airborne EM data, as a service. Latest improvement: nowimplemented and through acceptance tes�ng, is the capability for joint inversions of airborne EM and airborne IPsurvey data on any of the supported systems.
Standard funconality: Demonstra�ng the GeoModeller workspace for viewing, analysing and interpre�ng yourinversion outcomes – Below we show (1): A plan view of AEM survey SkyTEM SLM Ch27. Here a Noise Polygon isbeing selected (in orange) in a low-signal range region. (2): A noise file can then be generated for the polygon area(eg., by the Set Decay Reference method) for the two transmi�ers, as illustrated by the histogram view for theselected data.
Sea-g training events and a new maintenance release
Sea-gis a marine gravity APP, powered by INTREPID and designed to deliver on-cruise and post-cruise gravityreduc�on, QC and processing to high quality Free Air maps.
2017 saw the delivery of training events to customers in Indonesia and Australia. Customer feedback remarked thatthe whole process just became a whole lot simpler, combining: filtering, correc�ons, spliTng analysis, levelingcross-over analysis and gridding, in a stand-alone wizard. The annual maintenance release for Sea-g is now availableto customers, delivering a smoother and more stable user experience and bug-fixes.
Indonesian training also took processing to the Bouguer correc�on stage in the INTREPID graphical user interface,and we are now thinking to add this to ‘Sea-g’, provided the bathymetry grid is pre-prepared. More new featuresalready available in batch for Sea-g include automated line spliTng or turn removals (planned soon for addi�onwithin the APP).

On Saturday 21st October 2017 as part of the Explora�on ’17 workshops, our partners at the Centre for Explora�onTarge�ng, University of Western Australia (CET-UWA) presented a workshop on Uncertainty in 3D Modelling andInversion. The day-long event was a�ended by over 60 people, and included a significant segment on the rigorousgenera�on and analysis of model-families, via automa�on of perturbing structural observa�ons within thedata-model of a GeoModeller project – using implicit modelling approaches.
AGer hands-on exercises with GeoModeller and a ‘CURE’ wrapper to launch addi�onal code, par�cipants had theopportunity to discuss how these methods can lead to downstream applica�on for drilling op�miza�on, resourcees�ma�on, process simula�on and prospec�vity analysis.
