Abstract

A hydraulic pressure generator (14) provides pressurized fluid for actuation of well tools. The hydraulic pressure generator (14) comprises: a housing assembly (22); first and second fluid chambers (44,50) in the housing assembly (22); a piston (54) separating the first and second chambers (44,50); and a barrier device (42) isolating the first chamber (44) from fluid pressure in the well external to the housing assembly (22). The barrier device (42) is selectively actuatable to permit fluid communication between the first chamber (44) and the well external to the housing assembly (22), and thereby apply fluid pressure in the second chamber (50) greater than fluid pressure in the first chamber (44) by a predetermined amount.
