More details about the topic:
Globalization is a process of worldwide economic, political and cultural integration and unification, and it is inevitable in a free market economy. A big number of Russian companies have an opportunity to work abroad, and a large number of foreign enterprises are engaged in the oil industry in Russia. As a result, we have a large international team of specialists from various oil, service companies or joint ventures with the same goal. Under the prevailing circumstances, it is necessary to "speak the same language" with a clear understanding of the variety of terms of different scientific disciplines, since business philosophy of Russian and foreign companies may offen differ.
Consideration of the distinction between rocks and minerals is of vital importance in the petrophysical task of determining porosity and hence and also water saturation. Given the significance of this task, it is surprising how much confusion there is across the industry over this issue. The confusion of clay and shale is the most common, to the extent that a lot of books, papers, training courses and software products still do not differentiate them or explain this clearly or correctly.
Shale is a rock, typically defined as an indurated, finely laminated, sedimentary rock, composed primarily of clay, mud and silt. The important feature to note is that this definition does not describe the mineralogy but rather the grain size. In this definition, clay refers to clay sized particles, i.e. < 1/256 mm.
Whilst clay can refer to grain size, it can also refer to clay minerals and it is the dual meaning of the word clay that is at the heart of the confusion in the industry.
It is very important not to confuse clay and shale models as this simple error can lead to many problems: misunderstanding the difference between types of porosity; treating silt as a mineral when it is a grain size; shale computed with zero porosity; other low quality reservoir layers, such as siltstones, computed with zero porosity leading to them being modelled as zero permeability baffles, etc.
The report aims at disassembling this delusion, encourages participants to have a discussion in order to take a closer look at the terms of the "Western" and "Russian/Soviet" approaches in petroleum geology together.
