Production Allocation

Our Production Allocation services solve a common but complex challenge in multi-well and commingled production systems: determining which zones, wells, or reservoirs are contributing to the total hydrocarbon stream. Traditional allocation methods often rely on uncertain modeling or assumptions, but we utilize high-resolution geochemical fingerprinting, including molecular and isotopic analysis of oil and gas samples, to quantify each well's contribution over time, enabling operators to precisely map drained rock volume (DRV) and assess formation communication and well performance. By tracking unique chemical signatures across intervals and over time, we help operators detect unexpected contributions, validate zonal productivity, and refine reservoir management strategies.

 

This is especially critical in commingled horizontal wells, stacked reservoirs, and enhanced recovery operations, where understanding flow contribution directly impacts economics, decline curve analysis, and field development planning. Our data-driven approach reduces uncertainty, supports regulatory compliance, and helps maximize recovery with greater confidence.

Flexible Baseline Sampling

Baseline fluid families are established using core, sidewall core, cuttings, extracts, or produced fluids, allowing mathematical or statistical allocation models, tailored to project resolution needs.

Case Studies - Real World Impact: 

  • Eagle Ford (South Texas): Geochemistry confirmed that Lower Eagle Ford wells produced solely from their target formation, no Upper Eagle Ford contribution, justifying additional development target/sticks​​
