Key words: cationic, anionic-nonionic, polymer, structural-rheological properties, drilling mud, drilling, stabilization, borehole, inhibiting action, clays, rock, suprasalt, salt, basin, deposits, heat resistance, salt resistance.

The well casing and completion laboratory of LLC Gazprom VNIIGAZ has developed a new line of cationic drilling mud systems (Catburr) which do not have deficiencies typical of other drilling muds. Over 15 Catburr modifications have been analyzed and patented, including three mud systems which have been field-tested in suprasalt and salt deposits in Astrakhanskoye gas and condensate field. The findings show that cationic mud systems are highly effective in drilling through clay and salt deposits in the presence of high temperature and other aggressive environments. Following the field testing of cationic drilling muds, a decision was taken to proceed with drilling six production wells in Astrakhanskoye gas and condensate field, using the various Catburr mud systems.
