Dr.Seal is a simple Windows application for quick fault seal analysis. It can perform most common tasks in fault seal analysis such as: creates Allen diagrams, performs juxtaposition, shale smear, fault gouge (cataclasis) sealing analyses, and it can combine all these factors together to create an overall fault seal potential. It is created with limited data available in mind: as long as horizons and faults can be delinated from seismic survey, Dr.Seal can be used to perform early horizon juxtaposition analysis. When at least one well is drilled, Dr.Seal can use the well log data to perform more detailed analysis, and the reliability of the results will increase. Dr.Seal is a program written for geologists by a geologist.
The major capabilities and featurs of Dr.Seal:
* Basic analysis: performs basic juxtaposition analysis across a fault. This is useful at early exploration stage when no well data is availeble.
* Advanced analysis: Performs juxtaposition, shale smear, cataclasis analyses and the combination of the three. At least one well should be drilled to get permeability-related information. However actual permeability is not required. Any property data indicative of permeability (GR, porosity, density etc) will satisfy.
* Handles geobodies (channels, diapires) and unconformities.
* Handles Reverse Faults.
* Both real projected fault surface and triangulated fault seal diagrams. You can use real fault profile data to create real fault surface to do seal analysis, or create idealized, simplified triangular diagrams.
* Customer formula: For analysis of cataclasis fault seal factor.
* Superpose one diagram on another for easy analysis.
* Output images in .bmp, .jpg, .tif, .png, .tga and .emf formats.
* Directly edit diagrams: such as change attributes of labels and lines.
* Data files are ASCII files: You can use any text editor to create the files outside Dr.Seal, such as NotePad, WordPad, VI, emacs, vedit...
* Prepare data is easy: You can extract x, y, z from any seismic or geologic model, or digitized fault polygons from existing geologic maps.
* Windows based; developed with Visual C++; a 2-D application.

This is an idealized model analysis assuming all horizons and stratigaphic layers have the same dip, and every layer has the uniform thickness. This is similar to traditional triangulated diagram with added capabilities. Click on following links to view each diagram.

This is a real world sample with a lot more complexities. Both seismic data and well log data are used to define horizons and stratigraphic layers. Layer thickness and dip changes with position. Potential leaking location can be identified. Click on following links for each diagram:

Due to juxtaposition of a channel sand against a wet sand across this fault, a large amount of heavy oil has been depelated from an otherwise sizable reservoir. Both basic and advanced analyses have been performed for this fault.
