  1. In this exceptional study, Kejora Gasbumi Mandiri, in collaboration with PT Pertamina EP EOR, delivered top-notch results by inputting data into the cutting-edge tNavigator software, which performed hybrid computations with both CPU and GPU to accelerate probabilistic simulations. Our comprehensive process included:
  2. Verification and analysis of subsurface data to create a dynamic reservoir model.
  3. Comprehensive history matching analysis with assisted history matching using:
      • Custom
      • Grid Search
      • Latin Hypercube
      • Plackett Burman
      • Tornado
      • Monte Carlo
      • Box-Behnken
  4. Optimization for history matching, uncertainty analysis, and production optimization using:
      • Differential Evolution
      • Simplex Method
      • Particle Swarm Optimization
      • Response Surface (Proxy Model)
      • Artificial Intelligence
      • Ensemble
  5. Determining grid locations for property multiplier factors using Discrete Cosine Transformation.
  6. Enhancing accuracy with multiple objective functions, incorporating all Pertamina EP’s measurement data.
  7. Using calibrated models for future production forecasting with various development scenarios to achieve optimal hydrocarbon recovery.

This study aimed to automatically identify optimal well trajectories that maximize cumulative gas production under specified surface and well constraints. Using a history-matched model provided by Medco Team, Rock Flow Dynamics Indonesia (RFD) developed an automated workflow in the tNavigator Model Designer (MD) module, integrating existing MD calculations with custom Python code. The workflow utilized Assisted History Matching (AHM) with the Particle Swarm Optimization (PSO) algorithm to enhance forecast accuracy. The constraints included surface locations, dogleg severity, inclination, well length, and clearance to the gas-water contact (GWC), with a focus on the Upper North and West Sectors, which contain 24.5 MMSTB of OOIP and 1395 BSCF of OGIP.

The workflow was tested using three optimization methods: sequential, hybrid sequential-concurrent, and fully concurrent well optimization. The sequential method demonstrated superior stability and faster convergence, recommending 15 additional wells with a cumulative gas recovery of 864.8 BSCF (62% recovery factor) by January 2054. These wells maintained a constant production plateau for 165 months. The study recommends further work on hydraulic fracture design, geomechanically coupled simulation, and targeted horizontal drilling to enhance future gas recovery. This project highlights the expertise of Oil and Gas Consultancy in Indonesia and the advanced capabilities of Rock Flow Dynamics Indonesia in optimizing hydrocarbon extraction processes.

Our comprehensive scope of work offered unparalleled analysis of petrophysical and production data, featuring top-tier 2D seismic quality assurance and control, precise seismic horizon interpretation, and detailed fault boundary delineation. We excelled in time-to-depth conversion, velocity modeling, and structural analysis, delivering high-quality depth structure maps, residual maps, and thickness maps for each formation and reservoir. Our advanced 3D static geological modeling adjusted depth structure maps to well markers, created robust 3D grids, and validated structural models through meticulous QA & QC processes. We specialized in property modeling, including 3D modeling of petrophysical data like porosity, volume of shale, and saturation height, seamlessly integrated with geological and reservoir engineering concepts. Our services culminated in base case volumetric calculations and comprehensive sensitivity and uncertainty analysis to fully understand the impact of various parameters on your model. Partnering with us provided expert, innovative solutions tailored to elevate your oil and gas projects to new heights!
