ABSTRACT:
A portable pipe installation/removal support apparatus for assisting in the installation/removal of a series of connectable pipe strings from a ground-level borehole. The support apparatus has a base, an upright extending from the base, and, in an exemplary embodiment, a pair of catch arms extending from the upright to define a catch platform. The pair of catch arms serves to hold an upper connector end of a pipe string at an operator-convenient standing elevation by releasably catching an underside of a pipe coupler connecting two pipe strings of the series of connectable pipe strings. This enables an operator to stand upright while coupling/uncoupling the series of connectable pipe strings during the installation/removal thereof from the ground-level borehole. Additionally, a process for installing and a process for removing a series of connectable pipe strings is disclosed utilizing such a support apparatus.
