1. A system for monitoring downhole parameters, comprising:
a completion system deployed in a wellbore, the completion system having a hydraulic load sensor system, the hydraulic load sensor system comprising:
a housing;
a mandrel slidably received in the housing;
a compensating piston positioned between the housing and the mandrel in an expanded recess formed between the housing and the mandrel, the compensating piston being positioned to form a fluid chamber;
a sensor gauge able to monitor pressure in the fluid chamber via a pressure communication passage extending from the fluid chamber to the sensor gauge; and
a wellbore pressure communication passage in communication between a wellbore and the expanded recess on an opposite side of the compensating piston relative to the fluid chamber, the pressure in the fluid chamber as measured by the sensor gauge being used to determine axial loading.
