Problem Statement
- In the present era, reduction of interfacial tension is one of the crucial parameter in the field of petroleum engineering to enhance the production of trapped residual crude oil in the classic reservoir.
- Several studies noted that IFT does not reduce significantly with an increased temperature & salinity of the crude oil/water system during IFT measurement with an addition of conventional surfactants including other issues.
- Hence there is a need of eco-friendly process for increasing the residual oil production.
Technology
Present invention describes a composition for extracting hydrocarbons from a subterranean reservoir containing hydrocarbons, comprising:
(a) an ionic liquid, wherein the ionic liquid is selected from the group of lactam, ammonium, hydroxyl ammonium, imidazolium, piridinium, quinolidinium, isoquinolidium, and combinations thereof, wherein the ionic liquid has a concentration in the range of 10 to 100000 ppm,
(b) water, and
(c) salt, wherein the salt is an alkali metal salt, and has a concentration in the range of 50 to 500000 ppm,
- wherein the ionic liquid is selected from the group comprising of
 and combinations thereof,
- wherein n is 0 to 10;
- A is a negatively counter anion.
- R is C1-16 alkyl, wherein alkyl is optionally substituted with 1-4 substituents selected from the group of hydroxyl, nitro, halogen, -OR1, -COOR1, C1-6 alkyl, C5-10 aryl, C3-10 heteroaryl, wherein R1 is selected from the group of hydrogen, C1-16 alkyl, and C6-10 aryl, wherein alkyl and aryl are optionally substituted with hydroxyl, nitro, halogen, alkyl, and aryl.
- Further, said application describes a method of recovering and/or extracting hydrocarbons from a subterranean reservoir containing hydrocarbons using the said composition.
Key Features / Value Proposition
- Provides a process for enhanced oil recovery using lactam and hydroxyl ammonium based ionic liquids by enabling the reduction of interfacial tension (IFT) in the formation water reservoir,
- Facilitates enhanced recovery of residual crude oil from reservoirs.
- Small amount of ionic liquids (ILs) (in ppm) is very effective in enhancing the oil recovery.
- Overall recovery is about 70%, shows a great improvement in recovery factor.
- The process is indeed an economic intensive for upstream oil & gas industry.
