When Better Data Drives Better Decisions

Replacing Uncertainty with Measurable Reservoir Insight to Support Long-Term Development Strategy

Objectives

  • Quantify current oil and gas saturations in a cased-hole environment using the Raptor™ 2.0 cased-hole evaluation system processed through N-Vision and carbon/oxygen (C/O) spectroscopic modes.
  • Monitor the in-situ combustion front with high spatial and temporal fidelity by integrating new high-resolution data with legacy openhole logs and the 2024 cased-hole reservoir evaluation baseline.
  • Validate combustion front kinetics and determine whether the front was advancing in line with the thermal-kinetic model.
  • Reduce uncertainty in reservoir behavior and improve confidence for high-value reservoir management and development decisions.
  • Resolve ambiguity around heavy-oil conversion to gaseous phases and confirm the effectiveness of the ongoing in-situ combustion (ISC) pilot to support broader field expansion.

Our Approach

  • Deployed the Raptor 2.0 system in two monitoring wells in the high-resolution N-Vision and C/O acquisition modes, along with integrated pressure and temperature sensors, to diagnose reservoir conditions in extreme thermal environments.
  • Managed very high initial bottomhole temperatures of 450°F (232°C) and 368°F (187°C) through dedicated wellbore recirculation to stabilize temperatures to 256°F (124°C) and 283°F (139°C) for safe logging.
  • Acquired one N-Vision pass and three C/O passes after thermal stabilization to provide the statistical redundancy required for reliable saturation determination.
  • Applied advanced Interpretation and Evaluation Services workflows, including deterministic and stochastic petrophysical processing, to all Raptor 2.0 system-recorded curves and precision pressure and temperature gradients.
  • Integrated the 2025 dataset with historical logs and the 2024 baseline using an envelope-method interpretation workflow to build a multi-year comparative view of front progression and reservoir dynamics.
  • Used Monte Carlo response modeling and VC15 ratios to distinguish hydrocarbon gases such as methane from combustion by-products including carbon dioxide, nitrogen, oxygen, and water vapor.
  • Performed advanced spectral stripping and dry weight closure modeling to assess mineralogical changes in the seal and matrix caused by prolonged thermal exposure.
  • Leveraged the five-detector array of the Raptor 2.0 system to improve gas identification, residual oil saturation evaluation, and time-lapse interpretation in a cased-hole ISC monitoring application.

Value to Customer

  • Confirmed combustion front advancement in both monitored wells with some operational units progressing up to 25% relative to the 2024 baseline.
  • Identified a 7 to 10% increase in gas saturation, validating ISC efficiency in heavy-oil thermal cracking and gasification.
  • Replaced uncertainty with high-quality saturation and front-movement data, giving the operator the technical confidence to guide 2024–2025 reservoir management and workover planning.
  • Demonstrated repeatable, high-temperature performance during the second successful Raptor 2.0 system deployment, with data quality exceeding previous competitor tools.
  • Validated combustion behavior over a full 12-month monitoring cycle, reinforcing confidence in the pilot and supporting future field development expansion.
