communication with the interior of the tubing string 54 as defined by the space 55 a suitable shutoff valve 63 may be interposed in the conduit 60 and is normally open during operation of the method described herein the well 50 also includes a suitable annulus 62 defined by the casing 51 and the tubing string 54 and delimited by a conventional packer 64 for example the space 62 may be filled with pressure fluid by way of a conduit 66 in communication with the annulus through the wellhead 52 pressure gas may be introduced into the interior 55 of the tubing string 54 the space 17 and the conduit 60 by way of a compressor 70 in communication with the wellhead 52 for example the compressor 70 may also be connected directly to the conduit 60 or the wellhead 15 for pressurizing the space 55 the conduit 60 and the interior space 17 of the conduit 16 liquid may be introduced into the interior of the conduit 54 by way of a pump 72 operable to be in communication with the wellhead 52 so as to reduce the amount of space in the interior of the tubing string 54 occupied by gas as a method of compressing the gas in the space 55 the conduit 60.
