Title:
COMPOSITIONS AND METHODS FOR ENHANCEMENT OF PRODUCTION OF LIQUID AND GASEOUS HYDROCARBONS
Document Type and Number:
WIPO Patent Application WO/2014/182923
Kind Code:
A8
Abstract:
A well treatment composition is well-designed for the simultaneous enhancement of the production of both liquid and gaseous hydrocarbons from the same reservoir on a non-selective basis. The well treatment composition includes a first surfactant and a second surfactant, wherein the second surfactant is selected from the group consisting of ethoxylated alkylene amines, ethoxylated alkyl amines, propoxylated alkylene amines, propoxylated alkyl amines, ethoxylated-propoxylated alkylene amines and ethoxylated-propoxylated alkyl amines. The well treatment composition also includes a first solvent, a second solvent and water. Methods for using the well treatment composition include the steps of emplacing the well treatment composition into wells having high and low gas-to-oil ratios.
