The aim of the present study is to show that similarity of human natural languages can be conveyed not only by phonetic data, but also by grammar. The paper regards the largest typological database WALS and its possibilities in the sphere of genealogic relationship of languages. Using the method of two-objective optimization and data mining, which is new for linguistic studies, we show that grammatical (structural) data, as well as phonetic data, can deliver information on the similarity of languages. Language isolates and micro-families do not have genealogic relatives based on phonetic information, but they do have genealogic relatives based on grammar information.

The article presents results of the improved technology for drilling and completion of oil and gas wells (Multi-technology Complex). The results are based on synchronization and consistency of thermodynamic processes of well bore strengthening and implementing system approaches and solutions. The authors discuss brief analytical generalizations on the quality and efficiency of well lining, factors that violate the well lining technology, and related problems. In addition, disadvantages of traditional technologies and the reason for their low efficiency in the construction of wells are mentioned. The authors give analytical generalizations of the results of well construction with the use of the Multi-technology Complex in various mining and engineering conditions of Russian fields. The method’s advantages over traditional methods are noted. There are no occurrences of various complications in a well construction: fountains, emissions, gas-oil-water manifestations, absorption, instability and hydraulic fracturing of rocks. Furthermore, the complex allows improve well and filter structures reducing the metal intensity of the structure and the time frame.
