Sato Engineering & Infrastructure Limited

Oil & Gas Services

Consulting, engineering and digital technology services for the upstream oil and gas sector, delivered with our technical partners.

Capabilities

We help operators (independent, national and international oil companies) to maximize value from their existing assets (reservoirs, wells and facilities). Working with a partner team of internationally recognised subject-matter experts, we support the full field lifecycle: from field development planning and reservoir management to production optimization, digital twins, asset integrity and the procurement of production and surface processing equipment.

We apply innovative technologies and proven best practice to improve performance and efficiency, optimise costs, and manage risk and uncertainty.

Artificial intelligence, digitalization and digital twins, automation and autonomy

  • Project assessment, benchmarking and technology roadmaps
  • Real-time production optimization, from definition to implementation
  • Automation of petroleum engineering standards and business workflows
  • AI-assisted reservoir and production digital twins
  • Information management standards, workflows and solutions

Integrated asset management and production optimization

  • Reservoir, well and facility production proxy modelling, multi-sensor data assimilation and uncertainty quantification
  • Well operating envelopes and well integrity
  • Production monitoring and management of reservoirs, wells and facilities
  • Production capacity forecasting, production loss management and production enhancement

Field development planning and reservoir management

  • Field development planning, review, evaluation and optimization
  • Reservoir characterization and geo-modelling
  • Reservoir simulation and production forecasting
  • Integrated reservoir management standards

Also covered

  • Drilling services optimization
  • Asset integrity management
  • Mature field management
  • Virtual asset management for integrated energy systems

Solutions

Technology solutions

Subsurface and seismic

  • Seismic inversionStochastic seismic inversion using proprietary technology.
  • Time-lapse seismic analysisTime-lapse data integrated with production data and reservoir simulation, for dynamic reservoir characterization.
  • Simulation-to-seismic analysis

Field development and reservoir management

  • Field development planning
  • Mature field potential analysisStatic data such as seismic integrated with production data, with a thin-layer evaluation method, to evaluate mature field potential both laterally and in vertical cross-section.
  • Reservoir surveillance, monitoring and management

Production and facilities

  • Production optimization and enhancementAn injection allocation function determined from production data, integrated with seismic and other information where it is available.
  • Completions and wellbore interventions
  • Topside facilities management
  • Produced water management
  • Multiphase flow metrology
  • Process instrumentation, control and optimization

From surveillance to transformation

Each tier rests on the one below it: nothing is optimised that is not first analysed, and nothing is analysed that is not first measured.
