The importance of 3D modelling in designing a 18 km motorway from New Zealand’s Pūhoi to Warkworth

With an estimated cost of more than NZ $700m (including maintenance over 25 years), the 18km Pūhoi to Warkworth motorway extension includes a road corridor that cuts through steep hills and valleys, and the creation of seven bridges including three viaducts. Combine this with the cutting of 7 million cubic metres of earth (and the filling of 5 million)and the challenge of soft alluvial sediments – and it’s easy to see why a project wide ground model is essential as a basis for geotechnical design, and to mitigate project risk

Edit your surfaces in Leapfrog Geo like a pro

Using Leapfrog’s advanced surfacing editing tools, you have more freedom to shape your model and apply your geological skill and knowledge.

This blog summarises our recent advanced surface editing webinar and gives you access to the full recorded webinar.

The premise for the webinar is that with Leapfrog you use your available geological data to create a base model and then use Leapfrog’s advanced surface editing tools and your skill and knowledge to review and shape the model.

When geologists share, the mining industry benefits

When modellers collaborate, they work faster and think smarter. But getting them to share is not as easy as it sounds. The process needs to be effortless and automatic to deliver the best results, says Seequent Senior Technical Leader Julia Oliveira.

It’s hard to overstate how important collaboration is in our industry. Modelling is not a one-person game, or even a one-team game. When you try to model by yourself that only makes it harder, and that’s because geology is not a one-person truth.

Leapfrog Works 2.2 is out now with even more interoperability and data visualisation improvements

By their very nature engineering and environmental projects bring together multi-disciplinary teams who need to collaborate and communicate. but this is often thwarted by interoperability issues with specialist software. Experts who want to spend their time understanding and interpreting data, instead waste precious time manipulating software, their valuable skills lost on something that should actually be helping, not hindering.

Polymetal compares Leapfrog EDGE to Datamine

In a study carried out by leading precious metals mining group Polymetal International plc, new resource estimation solution, Leapfrog EDGE, was proven to achieve the same results as Datamine. The study also revealed many distinct advantages with Leapfrog EDGE, which applies the highly dynamic, intuitive and visual Leapfrog 3D capabilities to resource modelling. Leapfrog EDGE includes all of the industry standard tools you need most, for estimating, domaining, geostatistical evaluation and reporting.

Why a single source of truth has more than one advantage for the mining industry

Centralising all your data on one platform – such as Leapfrog Central – will dramatically improve your review process. But it also has a far-reaching and beneficial impact on your company culture, argues Seequent Senior Technical Leader Julia Oliveira.

It wasn’t so very long ago that if we needed to review models in the mining industry we would have to send pen drives from the mine to the head office – by plane. Imagine that! If you have to send data by plane, you have a problem.

Leapfrog Central

Even putting data on a server and then downloading it somehow seems too complicated in 2018 for something that should be simple and fluid. It’s also open to error. Centralising all your data on one platform gives you security, reliable version control, and makes sure everyone is working from the same model and can track its history.

But what’s meaningful about centralisation for me – particularly about using Leapfrog Central – is that it’s not just about process. It can also be about inspiration, recognition and better work. Because what’s surprising is that when you introduce new technology you can also introduce a new culture; a better, modern and more effective culture that can inspire your geologists to do more.

To get there you have to realise that talking to users and talking to managers about centralisation are two very different conversations.

What happens if all your teams are on the wrong page?

By Seequent Civil & Environmental Product Manager Pat McLarin

“If you design something based on out of date information, and perhaps order incorrect materials, the impacts could be cost overruns, scheduling hits or expensive machinery sitting unused.”

Was it version 8 or version 9?

Are your engineers working to the latest 3D model published this morning? Or are they about to make an expensive and time-consuming mistake because they didn’t receive the most up to date revision with that one key alteration?

Version management can be just as complex a process as wrestling with data interoperability – and could even carry more risk.

While geology is generally thought to be static, at least during a construction project lifecycle, our understanding of it will change dramatically as a project progresses.  New data will frequently change the design and details of a project, sometimes significantly. It’s vital to know that everyone involved understands there’s a new geological interpretation and is working from the correct one.

A New Dawn on the Data Horizon. Is the Energy Sector now facing their digital challenges?

Data and information management challenges are well documented and known across most industries. Where are files stored? How is information accessed? Is data up to date and reliable? Even adequate systems, processes and habits tend to devolve over time as roles and businesses change. The age of digital doesn’t seem to make things easier, but rather harder as we grapple with trying to knit the old with the new.

To discuss these big data challenges facing the energy sector today and what can be done about them, we spoke to Jeremy O’Brien Geothermal Energy Business Manager at Seequent, and Chris Hanton Technical Sales Executive at Perigon.

Creating an easily updatable Mined Geology Model in Leapfrog Geo

Ron Reid, Group Resource Geologist at Harmony GoldBy guest blogger, Ron Reid, Group Resource Geologist at Harmony Gold. Comments contained within are the authors alone and do not in any way represent the opinions of Harmony Gold.

I was asked the other day – can you filter the model for the mined / unmined material in Leapfrog. This got me thinking – the answer is yes but doing it once and only once is a lot of work to get a single result. If we flag a model as mined/unmined today, then tomorrow the result is wrong as we have mined some more. So I asked myself “Is there a way to create a mined model that is easily updated?” There is! It has been a while since I did a ‘how to’ post so I figured this might be a good topic to cover.

In Leapfrog Geo the terminology of the geology modelling process and workflow can easily impose a straitjacket on your thinking – create a geology model using erosion, deposition and intrusion surfaces. What you are in fact creating is a domain model using cutting, covering and slicing surfaces. Remove the geology straitjacket and you will see the domaining process can be used for anything. In this case we can use the cutting (erosion) and covering (deposition) surfaces to cut in a mined/unmined model. Then we can evaluate this model against the drilling, geology models and resource models to flag out the mined material.

WING Visibility Scholarship applications now open!

In April, we announced Seequent has signed on as the first Global Visibility Partner for Women in Geothermal (WING).

Founded in 2013, WING now has around 1000 members in 48 country teams in geothermal hotspots around the world from New Zealand to El Salvador to Denmark.

As WING’s Visibility Partner, we are proud to be sponsoring this year’s Visibility Scholarship.

Andrea (Andy) Blair, Global Chairman of WING, says: “Women need to be visible, in positions of influence, making decisions and leading, and serving as role models for those wanting to step into these roles too. We thought it was a really good fit to have Seequent as our partner in this area given their Leapfrog Geothermal software, used by many in the industry, provides the tools to enable visualisation and provide clarity.”

Open to all WING members, the scholarship will support speaking at the New Zealand Geothermal Conference in November. Seequent will provide flights, accommodation and conference registration for the successful applicant, chosen from conference abstracts screened by WING and Seequent.
