*** How volumes move from the wellhead to sales and how allocation ties the two together.
* The relationship between
** allocation engineering,*
* ** production engineering**,
** measurement**,
** operations**, and
** accounting**.
* Production reconciliation, facility balancing, and troubleshooting data discrepancies.
* How allocation accuracy impacts financial reporting, regulatory filings, and engineering analysis.
* Hands‐on exposure to real operational challenges in a producing asset.
** Key Responsibilities
**** Daily + Monthly Allocation Support
*** Assist with daily well‐level production allocation for oil, gas, and water volumes.
* Support monthly close activities, including comparing allocated volumes to tank strapping, meter readings, SCADA data, and production accounting system totals.
* Help identify and reconcile discrepancies in production data (e.g., well tests, theoretical to allocated analysis, tank measurement errors, facility imbalances).
* Validate PVT data and assist in generating updated well test inputs for allocation engines.
** Data Quality & Systems
*** Update and maintain production data in allocation systems (e.g., Energy Components, Pro Count, Avocet, Aries, TOW, P2 Merrick, or internal equivalents).
* Review facility balancing issues and support corrections to allow monthly allocation to close.
