Pipesim Simulation File
As deepwater oil flows up the riser, it cools rapidly. Using the thermal module, Pipesim simulation plots the fluid temperature against the hydrate dissociation curve. If the line crosses into the "hydrate zone," the engineer knows to add insulation or inject MEG (monoethylene glycol) before that node.
The hydrocarbon industry faces unique challenges: declining reservoir pressure, high water cuts, sand production, hydrate formation, and wax deposition. Pipesim simulation addresses these challenges directly. Here’s why it is indispensable:
PIPESIM utilizes Nodal Analysis to look at the inflow from the reservoir versus the outflow performance of the wellbore. By matching these curves, engineers can determine the optimal choke size, tubing diameter, and artificial lift method (like Gas Lift or ESPs) to maximize production. pipesim simulation
A real-world example: An operator in the Gulf of Mexico had three subsea wells tied back to a host platform 20 miles away. Production was limited to 40,000 bbl/d due to high backpressure, but the wells could deliver 60,000 bbl/d.
Using Pipesim simulation, engineers built a network model. The simulation revealed that the 8-inch flowline was under-sized for the gas volume (high GOR). The pressure drop in the flowline was 1,800 psi—too high. As deepwater oil flows up the riser, it cools rapidly
Two solutions were simulated:
The operator chose the flowline option based on lower OPEX. Without Pipesim simulation, they would have over-spent on pumps or undersized the new line. The operator chose the flowline option based on lower OPEX
Once the fluid reaches the wellhead, it moves through flowlines, manifolds, separators, and slug catchers. The network model accounts for:
