System and methodology for evaluation of distributed acoustic and temperature signals during well flows with heterogeneous inflow and outflow patterns

A simulation system for wells, the simulation system comprising:

• a circulation loop for circulating a fluid to simulate flows of fluid in a well;
• a data acquisition tool positioned with the circulation loop to interact with the fluid;
• a controller configured to obtain a distributed optical response from the data acquisition tool while the data acquisition tool is positioned in the circulation loop and the fluid is circulated in the circulation loop;
• and
• a simulation system controller adapted to update operation of the simulation system based on sets of operation parameters,
• wherein the sets of operation parameters define at least flow rates of the fluid in the circulation loop, and
• wherein a first set of the sets of operation parameters reduces the flow rates of the fluid to mitigate effects of the simulation system on the data acquisition tool and enable a baseline measurement of conditions impacting the data acquisition tool to be acquired.

• a return section in fluid communication with the wellbore simulation section and a fluid tank;
• and
• a perforation simulation section that places a first portion of the wellbore simulation section in fluid communication with a portion of the return section so that at least a portion of the fluid bypasses a second portion of the wellbore simulation section while the fluid is circulated in the circulation loop.
