1. Subsurface Evaluation & Integrated Geological and Geophysical (G&G) Studies

Innovative Workflow Deep Direct Hydrocarbon Indicators AVO (ddAV)

  • Purpose: Identifies AVO Class II/IIp (hidden prospects) and enhances characterization of hydrocarbon prospects in complex geological settings.

  • Key Features:

    • Rock physics modeling, seismic attribute analysis, and probabilistic simulations.

    • Overcomes challenges related to subtle seismic responses and low-impedance contrasts.

    • Provides a robust framework for de-risking and validating drilling targets.

  • Outcome: Optimizes exploration efforts in underexplored reservoirs with high reliability.

Our Subsurface Evaluation and G&G Studies service provides a comprehensive assessment of hydrocarbon potential using advanced seismic interpretation, rock physics modeling, and cutting-edge machine learning workflows. We specialize in AVO analysis, seismic inversion, and direct hydrocarbon indicator (DHI) identification, enabling precise de-risking of exploration targets. Our expertise spans structural and stratigraphic interpretation, reservoir characterization, and prospect maturation, ensuring that clients receive a high-confidence assessment of exploration opportunities. Our studies are designed to support strategic decision-making, providing an optimized path for future drilling campaigns while mitigating subsurface uncertainties.

Innovative Workflow Deep XGBoot Machine Learning (DGML)

  • Purpose: Integrates AVO analysis with machine learning to create a robust hydrocarbon prospecting approach AVO Class IIp.

  • Key Features:

    • Combines deterministic insights of AVO with advanced machine learning techniques (Gradient Boosted Decision Trees and deep neural networks).

    • Enhances detection of subtle hydrocarbon anomalies, particularly AVO Class IIp gas sands.

    • Uses seismic attributes, fluid substitution, and probabilistic modeling to mitigate seismic pitfalls and overlapping lithological signatures.

  • Outcome: Offers a transformative tool for hydrocarbon exploration, validated through forward modeling and field data.

  • Status: Registration with the UAE Patent Office scheduled for next month.

2. Drilling Planning & Well Execution Strategy

Our Drilling Planning and Execution Strategy service is focused on delivering cost-effective, technically robust well planning solutions that align with Planet One’s exploration and development strategy. We provide conceptual and detailed well designs, integrating pore pressure and geomechanical modeling, casing and tubing selection, and real-time drilling risk assessment. Our expertise ensures a safe, efficient, and compliant execution plan, utilizing state-of-the-art technologies such as dynamic modeling, MPD planning, and deepwater drilling optimization. Whether in Ghana, the UAE, or other offshore environments, we offer a flexible, scalable drilling roadmap that can be tailored to support single-well exploration or full-field development strategies.

WritRedefining AVO Classes: A Modern Perspective on Offset-Dependent Behavior

At CoreFlowMC, we challenge the traditional view of Amplitude Versus Offset (AVO) analysis by introducing a more dynamic and physically accurate understanding of AVO classes. Our latest research and field applications reveal that AVO class definitions are not constant, but rather offset-dependent, evolving with changes in seismic angle and subsurface response. This breakthrough allows for a deeper interpretation of amplitude behavior—where conventional Class I anomalies may transition into Class II or IIp at far offsets, often unlocking previously overlooked hydrocarbon potential. By embracing this modern definition rooted in advanced rock physics and supported by real-world data, our workflows significantly enhance the reliability of prospect de-risking and reduce the chances of drilling dry wells. This evolving AVO understanding is at the core of our proprietary ddAV technology, empowering more informed exploration decisions across complex geological settings.e your text here...
