Compositions and methods for enhancement of production of liquid and gaseous hydrocarbons

摘要

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.

主权项

1. A method of treating a plurality of hydrocarbon-producing wells, wherein a first of the plurality of hydrocarbon-producing wells has a high gas-to-oil ratio and a second of the hydrocarbon-producing wells has a low gas-to-oil ratio, the method comprising the steps of:
providing a complex nanofluid additive; emplacing the complex nanofluid additive into the first of the plurality of hydrocarbon-producing wells to lower the gas-to-oil ratio; and emplacing the complex nanofluid additive into the second of the plurality of hydrocarbon-producing wells to raise the gas-to-oil ratio.
