Fracture Models & Parameters

Our FRC workflow applies from well to domain and reservoir scale and generates concepts and parameters for software visualisations and simulations of the fracture system within the reservoir. It also supports volumetric calculations when fracture porosity is a key input, as well as the selection of drilling targets and well trajectories.

Successful fracture models depend strongly on careful data analysis. Over the years GeoScience has provided the fracture concepts and parameters for projects using many of the common modelling softwares.  We work with ERC Equipoise Ltd of  London (http://www.ercequipoise.com) to deliver a full workflow from data analysis to software-based fracture model. We offer:

• Multi-well studies and correlations
  
• Fracture mapping at outcrop and in remote sensing data
• Analog studies
• Integration of well and reservoir scale data to evaluate variations in well performance

And deliver:

• Static conceptual models of the fracture system with relevant parameters for simulation
• Conceptual prediction of fracture distributions

An example of a fracture model study from North Africa can be downloaded here.

Fracture Porosity

As noted above we can provide specific services in the estimation of fracture porosity for use in volumetric calculations as follows:

• Processing and interpretation of image logs and associated well data to derive estimates of fracture aperture and fracture porosity
• Assessment of likely range of fracture porosity from core and log data together with analysis of structural history and setting. We have built an analogs database from many years experience in the subject.
