The opening stages of the game gave neither set of fans anything to shout about and it took until halfway through the first period for a genuine chance to be created.
Brian Kerr released Calum Elliot down the Well left and the striker's cross found Richie Foran in acres of space in the six-yard box but the Irishman somehow turned his effort wide with the goal gaping.
Saints had been industrious and hard working without ever looking like testing Colin Meldrum.
The visitors did start the second half the better side and Meldurm was forced to palm out a Billy Mehmet cross before saving a Kirk Broadfoot header from a Simon Lappin free-kick.
Meldrum had to be at his best again minutes later to deny Kevin McGowne from a near-post header from a Richard Brittain corner.
Meldrum was the Well hero on 69 minutes as, after Marc Fitzpatrick had felled David van Zanten in the box, the veteran keeper denied John Sutton diving full-length to his right to keep his team in it.
In the dying seconds Tony Bullock had to look sharp to palm the ball off the head of David Clarkson.
