Prho™: Flow Assurance Surveillance Tool
GATE developed an integrable comprehensive flow assurance surveillance tool that, with one simulation run, allows the operator to:
Create PT Profiles: determine the current pressure and temperature profiles through water-oil-gas multiphase hydrodynamic calculation.
Perform a High-level Wax Risk Assessment: evaluate the temperature profile along the flowlines to determine where paraffin may potentially deposit.
Understand Flow Distribution: Calculate the production flow split / distribution through XOVs and evaluate the potential instability.
Confirm Water Sweep Velocity: Analyze the oil in-situ velocity along the flowlines and determine where it is not enough to sweep the water and causing water accumulation.
Determine Water Content: Calculate how much water is in the system and determine how much inhibitors required to inhibit the water from forming hydrates during shut in condition and subsequent restart.
Calculate Cool-down Time: Through transient cooldown simulation, calculate the duration until where fluid pressure and temperature are favorable for hydrate
Prior to delivering the surveillance tool, GATE conducted an extensive benchmarking study between the tool and the available field data to ensure it is representative of the actual field conditions.
