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
Fast and Reliable Core Analysis
Predict permeability and rock properties using a fast and non-destructive approach.
Visualize computations (here: flow field) to gain deeper insights about your rock structure, such as quantifying the properties of dominant flow paths.
From Core Analysis to
Reservoir Modeling
Take your data from GeoDict and scale from the
pore scale to reservoir scale using reservoir simulators,
as in the case of a classic oil reservoir in an anticlinal
trap with a pre-discretised grid.
Prediction of Rock Permeability
Reservoir model of an anticlinal trap showing the
calculated local and global permeability distributions
throughout the model.
Understanding the permeability distribution in the
reservoir is crucial for optimizing extraction strategies,
predicting fluid flow, and maximizing hydrocarbon
recovery while minimizing environmental impact.
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.
