The article discusses two series of the biodegradation tests of organic blockers used in drilling mud technology. Degradation process of the selected cellulose blockers in terms of quality was assessed by the colorimetric method. In all test solutions these tests revealed the presence of free glucose which is the final product of degradation of modified cellulose from which blockers were made. The beginning of the degradation process was noted already after 48 hours of the impact of enzymatic preparations on samples of blockers. The progress of the degradation process after 30 and 40 days of incubation was assessed by gravimetric method by draining sludge and marking blocker dry matter after enzymatic impact, comparing the sludge matter in samples with the specified enzyme to control samples without the addition of the enzyme. The research described in the work may be useful in the oil industry as they contain data (from laboratory-scale tests) on potential treatments with the use of enzymatic preparations. Detailed data on the degree of degradation of individual enzymatic preparations is included in the tables.
