Abstract
A method and a device for solvent injection in a subsurface well (1) where the solvent flows towards the formation wall (4) of the subsurface well (19) via a releasable duct (8).
Claims11
A method of injecting solvents in a subsurface well, the method comprising:
- delivering solvent to the subsurface well via a well completion pipe such that the solvent flows towards the formation wall of the subsurface well via a releasable elongated tubular duct that is external to the well completion pipe and that communicates through the wall of the well completion pipe.
A device for solvent injection in a subsurface well, the device comprising:
- a well completion pipe, wherein the solvent flows into the subsurface well via a well completion pipe, wherein the well completion pipe communicates with at least one releasable elongated duct located external to the well completion pipe and in the subsurface well, and wherein the releasable elongated duct communicates through a wall of the well completion pipe.
A method of injecting solvents in a subsurface well, the method comprising delivering solvent to the subsurface well via a well completion pipe, such that the solvent flows towards the formation wall of the subsurface well via a releasable elongated tubular duct that communicates with the well completion pipe, wherein the releasable duct is released by means of the solvent.
A device for solvent injection in a subsurface well, the device comprising:
- a well completion pipe, wherein the solvent flows into the subsurface well via a well completion pipe, wherein the well completion pipe communicates with at least one releasable elongated duct located in the subsurface well, wherein the releasable duct is connect to the well completion pipe by a releasable locking device, and wherein the releasable locking device comprises a soluble body.
