1. A method of operating a pipeline, the method comprising:
determining, based on observed operational parameters of equipment of an upstream process facility, an indirect quality parameter for processed production fluid output from the upstream process facility and routed into a pipeline downstream of the upstream process facility;
determining, based on measurements of characteristics of the processed production fluid output from the upstream process facility, a direct quality parameter for the processed production fluid;
determining a quality parameter for the processed production fluid that is defined as the greater of the indirect quality parameter and the direct quality parameter for the processed production fluid;
determining, based on the quality parameter for the processed production fluid, a model of the pipeline that comprises a cumulative water accumulation of a segment of the pipeline;
determining, based on the cumulative water accumulation of the segment of the pipeline, a water remediation schedule for the segment of the pipeline; and
conducting, in accordance with the water remediation schedule for the segment of the pipeline, a water remediation operation in the segment of the pipeline.
