Data Analytics & Shale-Gas Well's Design Optimization

By on

Hydraulic fracturing also called fracking is a WELL-STIMULATION technique involving the fracturing of bedrock formations by a pressurized liquid (see illustration above). The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of water and thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminum oxide) hold the fractures open. Hydraulic fracturing is used to increase the rate at which petroleum or natural gas can be recovered from subterranean natural reservoirs. Reservoirs, as depicted in Figure 1 below, are typically porous  sandstones ,  limestones,  or  dolomite  rocks, but also include "unconventional reservoirs" such as  shale  rock and tight sands . H

Enhance Athletes Performance Through Data Analytics & Recommender Systems

A couple of months ago I was contacted by a small training-fitness startup . They wanted to know if applying analytics techniques and methods could help them  answer some of their business questions and  enhance trainees' performance. I told them that indeed it was a doable task. However, they pointed out that the startup had limited resources, a small budget, and NO data... Now, I realized that the task at hand was a huge challenge... Indeed. So, h ow to tackle this challenge effectively, get the job done,  and deliver useful and actionable insight for this training-fitness startup? It was t ime to, again, think out of the box. The answer to these tough questions was to use some of  Google Workspace  cloud-based collaborative tools (Docs, Sheets, Slides, Forms), together with the  TRIFACTA  platform, and the open-source  R language comprehensive library; to design and implement an effective low-cost solution; serving the results as fully interactive tables and easy to digest visu

Visual and Predictive Analytics: FAKE/TRUE NEWS Classifier

FAKE NEWS ... A hot topic that has been around for many years and that recently has exploded and got hotter amid the COVID-19 pandemic. But, what exactly is fake news ? Fake news is false or misleading information presented as news.  It often aims to damage the reputation of a person or entity or make money through advertising revenue. Particularly for business, w hy is it relevant to analyze, characterize, and PREDICT fake news? At the same time that fake news is considered a serious threat to real journalism, they are also connected to stock market fluctuations and massive trades. For example, a few years ago  fake news claiming that Barack Obama was injured in an explosion wiped out 130 billion dollars in stock value. As I mentioned in my first post , in this and in future posts, I'll dive a little bit deeper into relevant examples of Data Analytics applications to real-life situations. In this post, I'm going to describe how it is possible to apply Advanced Visualization t
