The present invention provides a method of filtering a solvent-containing slurry stream including: (a) providing a solvent-containing slurry stream, the solvent comprising an aliphatic hydrocarbon; (b) depositing the solvent-containing slurry stream provided in step (a) as a filter cake on a filter medium, wherein a top layer of liquid is formed on the filter cake; (c) allowing the top layer of liquid as formed in step (b) to drain through the filter cake such that substantially no liquid remains on top of the filter cake; (d) allowing a gas to partially penetrate into the filter cake thereby obtaining a filter cake with a liquid solvent-depleted top layer; (e) passing liquid solvent through the filter cake with the liquid solvent-depleted top layer as obtained in step (d) thereby obtaining a washed filter cake; (f) removing solvent from the washed filter cake as obtained in step (e) thereby obtaining a solvent-depleted filter cake; and (g) removing the solvent-depleted filter cake as obtained in step (f) from the filter medium.

A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device. Each reader device can control operation of the tool associated therewith if the reader device is programmed to respond to signals received from the control device. Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool.
