A side pocket mandrel is described for use in well tubing, the mandrel comprising: a body having sidewalls, an open bore extending through the body in alignment with the well tubing, and a side pocket offset from the bore; a valve receptacle, in the side pocket of the body, for holding a valve, the valve receptacle having a mouth opening; and the body having integral, forged indentations formed by moving the sidewalls of the body radially inward at axially spaced locations beginning immediately above the mouth opening of the valve receptacle so that the indentations extend into the side pocket for a distance sufficient to keep tools other than the valve from contacting the valve receptacle, the indentations forming an undulating pattern which tapers away from the valve receptacle in a vertical direction.
