When should I use a Master Tank in Joyn Allocations??

Overview:

The Master Tank is a designated "tank type" that the Production Allocation (PA) system utilizes to represent a collective tank battery, comprising a group of individual tanks. It serves as a solution for scenarios where the accurate tracking of sales, transfers, and inventory from individual tanks within a tank battery is challenging.

Scenarios Warranting Master Tank Usage:

1. Run Ticket Ambiguity:

   • Issue: Run Tickets are reported, but the originating tank is not specified.

   • Cause: Run Tickets are randomly captured on any tank within the battery.

   • Solution: Master Tank helps consolidate run ticket data for better accuracy.

2. Single LACT Meter for Pipeline Sales:

   • Issue: Downstream Pipeline sales from the tank battery lack tank-specific information.

   • Cause: A single LACT Meter measures sales volume with no tank-level differentiation.

   • Solution: Utilize Master Tank to unify sales data from individual tanks.

3. Downstream Inventory Movement:

   • Issue: Inventory products (oil or water) moved downstream without tank-level tracking.

   • Cause: Lack of individual transfer check-meters for downstream transfers.

   • Solution: Master Tank acts as a unified inventory object for downstream tracking.

4. Transfer Ticket Ambiguity:

   • Issue: Transfer Tickets issued on a tank battery lack specific tank information.

   • Cause: Uncertainty about the origin and destination tanks for the transferred volume.

   • Solution: Master Tank provides clarity by treating the tank battery as a unified entity.

Implications:

In the aforementioned scenarios, the absence of accurate tracking for oil/water drawn from individual child tanks necessitates the adoption of Master Tank as a "unified inventory holding object." This allows the system, specifically JOYN, to provide a consolidated and precise overview of the entire tank battery's activities, ensuring better control and management of the oil and gas production allocations.
