FIELD: chemistry; oil and gas industry.
SUBSTANCE: invention relates to the field of gas production, in particular to chemical reagents for removing liquid from wells of gas fields, whose products contain a condensation liquid. Reagent for removal of condensation liquid from gas wells, containing a nonionic surfactant – OC-20 preparation, additionally contains an anionic surfactant – sodium lauryl sulphate with the following ratio of components, wt%: OC-20 80–85, sodium lauryl sulphate 15–20.
EFFECT: ensuring effective removal of condensation liquid from gas wells using a surfactant.
