Abstract:
1. A well pumping system comprising: a substantially straight length of coiled tubing extending generally vertically between an upper end at a surface of a well and a lower end; a first electric pump and a first electric motor; a sealing means that seals against a side of the well above the lower end of the coiled tubing; the sealing means including a first fluid path through which the coiled tubing is in fluid communication with the well beneath the sealing means, and a second fluid path through which first electric pump extends above and below the sealing means and is in fluid communication with the well beneath the sealing means; the coiled tubing allowing passage of a tool through the coiled tubing past the lower end of the coiled tubing below the electrical submersible pump while the tool is attached to a wireline past the lower end of the coiled tubing below the electrical submersible pump; and a valve means including a packer portion, the valve means being disposed above the sealing means and the electric motor and electric pump but beneath the surface of the well, wherein the valve means can be activated to provide a seal against the side of the well and an outer surface of the coiled tube.
