Abstract: 
Досліджено й охарактеризовано важкі нафти з родовищ трьох областей України (Львівської, Сумської та Полтавської). Для зневоднення цих нафт розроблено та досліджено ряд композицій з використанням деемульгаторів Dissolvan. Підтверджено синергічний ефект оксіетильованих та оксипропільованих блок-кополімерів. Для зменшення в'язкості і підвищення ефективності зневоднення нафти розріджували важким газовим конденсатом. Для кожної досліджуваної нафти були визначені оптимальні склади деемульгаторів. Чотири композиції, які показали найвищу деемульгуючу здатність (90-94,5%) при роботі з досліджуваними нафтами, відібрано для подальших досліджень.
