During the 1960s and 1980s, when oil and gas exploration began, these black gold reserves were not very deep in the earth's crust. This did not require the drilling fluids to contain cellulose ethers of high molecular weight and various modified components. At this time, oil and gas deposits were produced from formations with a depth of 1.7-2.9 km. In this case, the probability of destruction of drilling fluids continuously directed into the wells was much lower, during drilling the temperature was 80-1200 ° C. At such temperatures, the decomposition of elementary rings of natural polymer macromolecules based on ether in drilling fluids was practically impossible
