What is Geological Modeling and its Comparison to Blueprints?

The process of creating a geological model significantly differs from creating an architectural blueprint. Chiefly, a geological model will never match a blueprint in terms of precision, even after exhaustive drilling exercises. Rather, geological models should be perceived as experimental apparatus—akin to sculpting landscapes within a sandbox. Its core appeal lies in uncovering and scrutinizing the uncertainties that lie beneath the Earth’s crust.

• Geological Models are experimental apparatus;
• They are instruments for exploring uncertainties;
• They inherently differ from architectural blueprints.

While visually compelling representations produced by geological models are indeed captivating, they may inhibit the understanding of their true potential. These graphical representations may sometimes be overly convincing, leading stakeholders to misconceive them as absolute truths or precise blueprints.

The Quest for Precision vs. Appreciation for Uncertainty in Geological Modeling

Oftentimes, stakeholders like managers, drillers, completional experts, and even geoscientists primarily seek a more precise blueprint of the subsurface. This perception limits them to the role of designers and creates conflict when the geological model fails to accurately predict future observations. However, unlike blueprints, models should inherently encapsulate uncertainties and simplify assumptions.

• Geological Models should include uncertainties and assumptions;
• The quest for precision can often lead to limitations;
• Understanding the difference between accuracy and precision.

The geological assumptions of designers are often widely accepted and enthusiastically endorsed by the industry due to several factors. One key factor is the lag in scientific advancements keeping pace with technological progress. Another is our inherent preference for quick, straightforward, and easily understood explanations. Sadly, the complex wonders of geology do not lend themselves to such simplistic reductions.

Embracing Uncertainty, the Heart of Geological Modeling

In the face of the unknown, it’s human nature to seek solace in a single solution. Dealing with uncertainties is more challenging than ignoring them, and a precision model seems more appealing than a range of probable solutions (despite precision and accuracy not necessarily being coincident). Opting for a blueprint-like model, rigid and tightly constrained, seems relatively easier as it relieves us from the pressing ‘what ifs’.

• Embracing uncertainties is at the heart of geological modeling;
• Precision and accuracy are not synonymous in this context;
• The importance of entertaining ‘what if’ scenarios.

However, the true essence of geological modeling lies in exploring these uncertainties and questioning assumptions. For instance, pondering over diverse scenarios such as a 20m fault throw instead of a 10m one, or considering the possibility of an oil reservoir instead of a water one, or contemplating on the likelihood of an increased pore pressure downdip.

Conclusion

In summing up, it’s crucial to perceive geological modeling not just as a meticulous blueprint akin to the certainty often found in comic book science, but as an opportunity for exploration and questioning. The pursuit of precision, much like the fantastical resolutions in comic book narratives, often overshadows the inherent uncertainties and assumptions within these models, limiting their potential for discovery. Hence, embracing uncertainty, exploring various possibilities, and continuous iteration form the cornerstone of effective geological modeling. It’s high time we move away from rigid constraints and delve deeper into the intricacies, questions, and wonders that geological modeling presents. This approach fosters a more dynamic and fruitful understanding of the world beneath us, stepping beyond the simplified and absolute answers often celebrated in comic book science to embrace the complex reality of our planet.

The Power of Open Source for Budget-Minded Enterprises

For entities that are financially constrained, open-source platforms serve as a fervent ally. However, the benefits of the open toolbox extend beyond the cost factor. An open toolbox exhibits minimal dependence on hardware and is less inclined towards specific workflows. This flexibility is crucial in maintaining agility and adaptability in a rapidly changing digital environment.

Moreover, steering clear of substantial technology investments allows us to evade the daunting trap of vendor lock-in, ultimately circumventing the consequential data lock-in. Here are a few crucial benefits of open source:

• Full Transparency: With open-source platforms, the software’s behaviour is like an open book as one can review the source code and understand the software’s functionalities profoundly;
• Customizability: Moreover, it allows users to tailor the software according to their unique requirements. This customizability is possible because users can modify the source code to suit their needs.

These two aspects distinctly highlight the advantage of open-source platforms over conventional ones. Many might recall the daunting scenario when a software vendor takes an eternity to amend a bug or introduce a new feature. Worse still, after finally getting the update, it might take the organization another year and a half to implement the new version of the software.

A New Perspective On Tools We Use

One of the most frequently asked questions is about the software and hardware employed for our operations. Here’s a comprehensive breakdown of the tools:

Hardware: The team utilizes a variety of hardware. Some prefer dual-screen Apple iMac with OS X 10.6, while others favor Samsung Q laptops with solid-state drives and Windows. A transition to Mac Pro is under consideration, owing to their exceptional performance and design. However, Linux-based systems also present an attractive option due to their flexibility and customizability.

Geoscience Interpretation: The primary tools include dGB OpendTect, GeoCraft, and Quantum GIS. However, there’s a gap for a log visualization and interpretation tool. Some other resources in use include Madagascar and GMT, integrated with OpendTect. TimeScale Creator proves valuable for plotting stratigraphic charts. It’s important to point out that despite advanced tools such as GeoProbe being available at a high cost, open-source tools like OpendTect are free and offer competitive performance.

Data Analysis and Mining: Excel, Spotfire Silver, MATLAB, GNU Octave, and Python significantly contribute to data mining. Other tools employed include Gephi for network analysis, FIJI for image analysis, and VISAT for remote sensing images. Mobile app development leverages MIT AppInventor, and current explorations are underway with the PhoneGap framework in Eclipse.

Writing and Illustrating: Google Docs, Inkscape, GIMP, iMovie, and Adobe InDesign are the go-to tools for content creation. Microsoft Office and OpenOffice.org are also used occasionally. For managing references, Mendeley proves to be a fantastic tool.

Collaboration: In the era of remote working, collaboration tools like Skype, Dropbox, Google+ Hangouts, and various other Google tools are indispensable. Asynchronous collaboration and documentation are facilitated using wikis, especially SubSurfWiki. Social media presence is maintained via Google+, Facebook, LinkedIn, with Twitter being the primary channel.

Web: The websites are hosted by Squarespace, to ensure reliability and reduced maintenance. MediaWiki instances run on Amazon’s Elastic Compute servers for flexibility. Another website is in the pipeline, running WordPress on Amazon EC2. Domain names are sourced from the Canadian company Hover.

Administrative Tools: For smooth business operations, Tick is used for time tracking— an essential tool when juggling multiple projects. Accounting is streamlined using Wave after having experienced several other less effective products.

Conclusion

In the grand scheme of business operations, the essence of success lies in making the most of available resources. Approaching technology with a balanced perspective, leveraging the power of open-source software, and harnessing the potential of advanced tools can significantly enhance operational efficiency. It’s a testament to the concept that victory is not always about possessing more, but about making the most of what one has at their disposal.
