FIELD: oil and gas production.
SUBSTANCE: invention, in particular, relates to clayless drilling mud used for boring and completion of wells, including horizontal ones and offshoots, which drilling mud 0.2-0.25% bactericide (LPE-11), 0-0.35% soda ash, 1.5-3.5% starch (FITO-RK), 0.4-0.75% biopolymer (Robus), 1.0-2.0% ferrochromolignosulfonate, and water - the rest.
EFFECT: improved quality of primary exposure of "exhausted" producing oil reservoir having low formation pressions.
