Chemical composition of water-based drilling mud filtrate as the most important quality indicator
The paper presents the results of laboratory studies of the chemical composition of the filtrate of mineralized starch-biopolymer drilling mud, the influence of the filtrates of the studied drilling fluids on the drilling parameters, on the filtration and capacitance properties of carbonate and terrigenous oil-saturated deposits of Udmurtia deposits. The studies were carried out on samples of drilling fluids, core material, oil and reservoir water samples.
