A method for operating water wells at optimum rates involves obtaining, for each of a multitude of wells, a target rate of fluid flow, obtaining, for each target rate of fluid flow, a corresponding target differential pressure using orifice performance curves stored in a database associated with the multitude of wells, and monitoring each of the multitude of wells for noncompliance. Noncompliance is determined based on a rate deviation of an actual rate of fluid flow from the target rate of fluid flow exceeding a predetermined threshold. The rate deviation is determined based on a differential pressure deviation of a measured differential pressure corresponding to the actual rate of fluid flow from the target differential pressure corresponding to the target rate of fluid flow. The method further involves bringing a non-compliant well of the multitude of wells into compliance.

Method and system for operating wells at optimum rates using orifice performance curves

A wireline operation method is disclosed. The method includes disposing an outer diameter (OD) meter ring on a wireline, the OD meter ring having spring-loaded sensors, releasing, from a spooling drum into the wellbore, the wireline via a wireline passage having a tight spot, a released portion of the wireline progressively passing through an opening of the OD meter ring, generating, using the spring-loaded sensors, a real time OD measurement of a current location of the wireline passing through the opening of the OD meter ring at the time of measurement, generating, in response to the real time OD measurement of a particular location of the wireline exceeding a pre-determined threshold, a fail-safe signal, and stopping, in response to the fail-safe signal, the spooling drum from continuing to release the wireline before the particular location of the wireline reaches the tight spot of the wireline passage.
