What is UHRGC?

Ultra-High-Resolution Gas Chromatography (UHRGC) is GeoMark Research's cutting-edge analytical method that significantly advances the capabilities of traditional High-Resolution Gas Chromatography (HRGC). While HRGC has long been the industry standard, offering approximately 80 integrated peaks across five compound classes, UHRGC dramatically increases resolution, delivering 192 integrated peaks, including 133 identified compounds and 59 generic IDs.

Why is UHRGC Different?


  1. Enhanced Resolution: UHRGC captures a broader range of hydrocarbons, offering unparalleled detail in chemical profiling. This method identifies almost 2.5 times more peaks than HRGC.


  2. Improved Sensitivity: The enhanced resolution enables the differentiation of subtle compositional differences that HRGC cannot detect.


  3. Advanced Compound Identification: The method integrates synthetic standards to validate peak identities and confirm unknown compounds, enhancing reliability and repeatability.


  4. Broader Applications: UHRGC analyzes not just crude oils but also produced fluids, aiding in reservoir characterization, connectivity studies, and production allocation.


Applications of UHRGC


  1. Reservoir Connectivity Studies: By comparing the chemical profiles of oils from different wells, UHRGC can determine the likelihood of communication between reservoirs. For instance, a cosine similarity threshold of ≥0.90 indicates strong connectivity, offering critical insights for development planning​​.


  2. Time-Lapse Geochemistry: UHRGC tracks fluid changes over time, helping operators assess reservoir depletion, zone communication, and infill opportunities.


  3. Oil Allocation and Source Analysis: The method identifies distinct chemical fingerprints of fluids from various reservoirs, enabling precise production allocation and better understanding of hydrocarbon sources​​.


Why Choose GeoMark’s UHRGC Over HRGC?

GeoMark's UHRGC sets a new benchmark for hydrocarbon analysis:


  • Data Precision: With a higher number of analyzed peaks, UHRGC offers unmatched detail, capturing both lighter and heavier hydrocarbons across a broader range (nC4 to nC40+).


  • Strategic Insights: The method is pivotal for addressing challenges in unconventional reservoirs, such as understanding fluid heterogeneity, migration pathways, and connectivity.


  • Cost Efficiency: By revealing detailed fluid dynamics, UHRGC enables better-informed decisions, reducing risks and optimizing field development.


Real-World Impact

GeoMark’s UHRGC has been successfully applied in key projects:


  • In a recent Southeast Asia reservoir connectivity study, UHRGC's advanced analysis demonstrated strong chemical similarity (cosine similarity of 0.9569) between two wells, suggesting shared reservoir resources.


  • In the Delaware Basin in West Texas, UHRGC illuminated variations in oil compositions, aiding in understanding vertical connectivity and out-of-zone contributions during production​.


How Does UHRGC Help You?

Whether you're an operator seeking precise production allocation or a researcher exploring new reservoir development opportunities, GeoMark's UHRGC equips you with the most advanced tools for:


  • Optimizing well placement and completion strategies.


  • Understanding reservoir compartmentalization and communication.


  • Enhancing confidence in hydrocarbon characterization and resource potential.
