1. A method for supporting a sucker rod string and associated downhole pumping equipment on a tubing string inlet or an upper extension thereof, during preparation of a wellhead for suspension of an oil or gas well, the method comprising:
a) lifting and supporting the sucker rod string and partially disassembling the wellhead to expose an uphole end of a sucker rod of the sucker rod string;
b) engaging a support tool to a portion of the uphole end of the sucker rod, the support tool having:
i) an upper wide diameter portion with a substantially horizontal landing surface wider than the inner diameter of the tubing string inlet or the upper extension thereof, and
ii) a lower narrow portion configured to fit inside the tubing string inlet or the upper extension thereof,
iii) a central interior longitudinal cavity spanning the length of the tool, the cavity continuous with a longitudinal slot in the outer sidewall of the tool spanning the length of the tool, wherein the sucker rod is held within the longitudinal cavity and the longitudinal slot allows passage of the fluid or gas when the tool is supported on the top edge of the tubing string inlet or the upper extension thereof, wherein the upper wide diameter portion consists of a uniform cylindrical shape extending between edges of an upper portion of the longitudinal slot, and wherein the upper portion of the longitudinal slot is continuous with an upper portion of the central longitudinal cavity, wherein the longitudinal cavity has an inwardly tapered portion beginning at the upper surface of the wide diameter portion and the inwardly tapered portion is dimensioned to retain a lower portion of a sucker rod upset of the sucker rod, and
c) lowering the sucker rod string into the tubing string inlet or the upper extension thereof, until the lower narrow portion enters the tubing string inlet or the upper extension thereof, and the landing surface of the support tool rests upon the top edge of the tubing string inlet or the top edge of the upper extension thereof.
