Simulations in Digital Rock Physics & Digital Core Analysis

for the targeted extraction and development of oil and gas reservoirs

Field development decisions are guided by reservoir models and drive reservoir lifecycle. Decisions need to be precise and fast, and quality of models is crucial. Models depend on proper investigation of rock sample properties, such as rock core plugs or cuttings.

Rock properties are determined either through physical core analysis in a laboratory or by numerical core analysis using simulations, also called Digital Rock Physics.

DRP - the innovation for core analysis

Digital Rock Physics (DRP) is an innovative technique for numerical core analysis in the Energy upstream sector. For the following aspects, it enables:

  • E&P (Exploration & Production):
    Automation of Routine Core Analysis (RCAL) and Special Core Analysis (SCAL).
  • R&D (Research & Development):
    Development and validation of company- and application-specific digital workflows.
  • EOR (Enhanced Oil Recovery):
    Improving recovery rates (e.g., Water Flooding)

The input data from DRP can be used to calculate and upscale the permeability for complete reservoir model (modeled at the kilometer scale). Based on these simulations, further field development decisions can be made, e.g. the placement of new production wells.

DRP offers the following advantages as a supplementation or substitution of laboratory analyses:

  • enormous time and cost optimization – obtain results in just hours instead of days, weeks or even months
  • quicker results lead to shorter time to production
  • performing multiple numerical experiments on exactly the same sample (non-destructive technique)
  • conducting different analyses simultaneously on one sample
  • allowing parameter studies of rock properties under multiple scenarios
  • testing of different production strategies and improving recovery scenarios

GeoDict Simulations in Digital Rock Physics & Digital Core Analysis

Computer simulations with GeoDict help reservoir engineers and geoscientists to digitalize and automate the analysis of physical rock properties. GeoDict outputs the following:

  • Geometric properties
  • Absolute permeability
  • Relative permeability
  • Electrical properties: Formation factor, resistivity index, saturation exponent, cementation exponent
  • Mechanical properties: Elastic moduli, stiffness, in-situ conditions

Through the computer simulations with GeoDict, new insights into the physical processes occurring in the rocks are obtained and will help you facilitate better understanding of reservoir behavior.

Running computer simulations with GeoDict can be used to:

  • Compute the physical rock properties determined during Routine Core Analysis (RCAL) and Special Core Analysis (SCAL).
  • Evaluate the quality of laboratory based analyses.
  • Simulate reactive transport processes, such as carbonate dissolution.
  • Predict the results of experiments in microfluidics systems.

The material properties of rock samples under in-situ conditions are also determined through digital analysis and the simulation of pressure and temperature conditions.
