1D Fault Seal Analysis
T7's in-built 1D fault seal analysis (Triangle) provides a way of assessing juxtaposition and fault-seal potential at various fault throws for any given input stratigraphy or well curve. The main benefit of Triangle is that the analysis is fast and simple to use. But its use is not restricted to "quick look" problems as it can also be a valuable tool for determining sensitivities to property and structural uncertainty in more fully fledged studies.
T7 Triangle Features
As an integrated T7 product, Triangle readily accesses curve and interpretation data from 3rd party applications.
In Triangle Direct mode the user to can run fast analysis using only a vshale (or gamma-ray) curve and horizon tops (i.e. without the requirement for well trajectory or auxiliary information).
Triangle supports the same fault seal attributes as T7 and its output may be modified or extended using AttCalc (Attribute Calculator). Some of the default attributes that are available are listed below:
- Shale-Gouge Ratio (Discrete / Continuous Modes)
- Clay Smear Potential (Shell / Yielding Methods)
- Shale Smear Factor
- Threshold Capillary Pressure (Bretan, Sperrevik / Yielding)
- Maximum Supportable Hydrocarbon Column Heights (Bretan, Sperrevik / Yielding)
- Fault Zone Permeability (Manzocchi / Sperrevik)
- Transmissibility Multipliers (Manzocchi / Sperrevik)
- CO2 Related Parameters
Triangle also has access to well curve editing functions. Therefore, you can test cases that have, for example, been made more or less shale-prone, or test logs built from stochastic models.
