Despite the relatively small sample size of 28 paired measurements, the prior baseline study provided sucient data to identify a signicant and non-trivial issue: the substantial disagreement between the two popular, whole-facility, TD methods for these midstream facilities. This research aims to examine the divergence between these TD methods. To achieve this, we engaged the same two TD methods to perform more extensive repeat measurements at each facility during the EOP project phase. Additional repeat estimates address a fundamental experimental question from the prior study: Is the inconsistency observed between the TD methods a consequence of limited sample size, or a more substantial disagreement between the methods? It is worth highlighting that one facility was sold during the QMRV project term; thus, the facility did not participate in EOP measurements, leading to a reduction in the total number of facilities from 15 to 14.
