In short
Pro-Hub's allocation engine models wells, meters, tanks, equipment and facilities as a multi-tier network, then allocates measured volumes back to each well and completion using date-effective rules.
Allocation is where measured volumes become accountable volumes. Pro-Hub gives engineers and production accountants a schematic module to draw the system as it physically exists: wells into headers, headers into tank batteries, compressors, gas lift loops, shared facilities and plants.
Every node and rule carries an effective date. When a well is tied into a new facility or a meter is replaced, the network changes from that date forward. Historical results remain exactly as they were calculated.
