Big data, in its many forms, has promised much to the oil and gas industry but mostly is perceived to have been slow to deliver. This is not at all surprising. We must walk before we can run, and, as experience has grown with the nuances and successful and unsuccessful avenues of investigation, the industry has continued to move forward. As the saying goes, “Data is like people: Interrogate it hard enough and it will tell you whatever you want to hear.”
From early and almost naïve beginnings, where systems would confidently predict that Friday followed Thursday, we entered a phase where data mining began to provide insight. Often these insights confirmed long-established relationships; for example, in hydraulic fracturing, more than once I have seen heavily marketed research and development that professes to predict the onset of screenout conditions only to see that the system has effectively “seen” a Nolte-Smith relationship. These, however, are mere stumbles of any system picking itself up and beginning to move, and should be expected.
What we have seen are continued areas of application opening up, where approaches deliver real efficiency gains and highlight further opportunities. The papers that I included this month fall into these categories, demonstrating real measurable efficiency gains and advantages, often processing volumes of data that previously could not be managed by conventional means. Performance measurement and drilling automation are two such examples, and the papers referenced this month, both as synopses and listed for further reading, fall into this category.
Not surprisingly, as we apply data science to broader problem sets across the industry, we will see continued development and demonstrated success. Sharing these successes will ensure that this momentum is sustained and that advances continue.
