The impact of the Cumulative Hydrocarbon Column technique goes beyond theory and has directly influenced significant patents in the petroleum industry. In the second and final part of this series, we'll explore how the article mentioned in Part I, which is one of our most referenced articles on the internet about petrophysical cutoff calculation, has inspired and influenced a French patent and a European patent granted to Schlumberger. Why are patents so important for Schlumberger, the oil and gas industry, and the industry as a whole?
The Importance of Patents
Patents play a crucial role in shaping global trade policies. Halliburton is a good example of the oil and gas industry's shift towards patenting. Halliburton and Schlumberger are the largest US service providers in North America. Historically, Schlumberger dominated the international markets, while Halliburton focused on North America. However, as the energy market has become more competitive, the two giants are increasingly encroaching on each other, and the battle between the two is heating up.
It seems that Halliburton is using patents as a competitive tool. In 2013, Halliburton received about 150 fewer granted patents than Schlumberger. However, after sustained growth, Halliburton has now surpassed Schlumberger, receiving 738 granted patents in 2017, which is 304 more than its rival and represents a 35% growth compared to the previous year (see here and here).
How to Calculate Petrophysical Cutoffs: French Patent FR3024490A1
Acting accordingly, Schlumberger took the initiative to secure the patent for the methodology of computing petrophysical cutoffs, first in France, and subsequently in the European Union.
The first achievement was obtained through the INPI (Institute Nationale de la Propriete Intellectuelle). To find out more about the INPI, click the image above. As a reference, find below the official patent certificate, expiring in the year 2034:
How to Calculate Petrophysical Cutoffs: European Patent EP 31752674 A4 20180418
After completing the necessary analysis and revision processes through the European Patent Office (EPO), Schlumberger moved on and was granted the patent. Click on the image below to learn more about the EPO.
Below is the detailed information from the EPO regarding the patent under consideration:
In summary, calculating petrophysical cutoffs is crucial for reliable formation and reservoir assessments, whether dealing with existing cutoffs or establishing new ones.
