Abstract
A computer-implemented method, medium, and system for determining contributing inflow control devices (ICDs) using transient pressure data from a permanent downhole monitoring system (PDHMS) in a wellbore is disclosed. One example computer-implemented method includes receiving transient pressure data from a PDHMS in the wellbore. Multiple ICDs are installed in the wellbore and include multiple contributing ICDs that contribute to fluid flow in the wellbore. Curve fitting of multiple composite exponential signals is performed to match the transient pressure data. A total number of the multiple contributing ICDs is determined based on a result of performing the curve fitting. A respective normalized distance between each pair of adjacent ICDs of the multiple contributing ICDs is determined. A depth of a last ICD in the multiple contributing ICDs is determined. A list of all contributing ICDs is generated based on the determination of the depth of the last ICD.
