### SG2PS (STRUCTURAL GEOLOGY TO POST SCRIPT CONVERTER) IS:

- Graphical application for
**field**and**well structural data**evaluation and processing. **Free**and**open source**software.- Easy to use
**Graphical User Interface**, data processing takes just a few clicks. **Separate processing**and plot for different wells, localities, data types, data groups and formation.- Displays well structural data on
**well plots**, and field data on**stereonets**and**rose diagrams**. **Tectonic transport direction**display and**mean transport direction**calculation.- Displaying
**multiple data groups**on the same stereonet. **Bedding correction**for tilting test available.**Trajectory correction**for borehole data is supported.**K-means clustering**to identify data groups in an inhomogeneous data set.- Eight different
**inversion methodologies**and**fracture geometry statistics**. - Data input in
**Excel**or any other**spreadsheet**application of your choice (such as**OpenOffice**or**Gnumeric**). - Output in Adobe Portable Document Format (
**PDF**) for individual files, and a single**merged**file. - Optionally, Encapsulated Post Script (
**EPS**) is also available as output format, useful for publications. - Both output options are possible in
**grayscale**as well (ideal for gray scale publications). **Rich documentation**.

### WELL DATA PROCESSING MODULE

#### CAPABILITIES:

- Average calculation for structural trends:
**average**feature**dip direction / dip angle**calculation along well bore using**fix data number bin**or**fix interval bins**. **Standard deviation**and**relative error**calculation for the processed bins.- Feature
**frequency**calculation. **Derivate**curve to show**out-of-trend**zones: investigation of out-of-trend zones using first derivate curve of the average and frequency curves.**Peak detection**for deformation zones: changes on average, frequency and derivate curve can indicate a zone of deformation.- Faults probability: abrupt
**change**in**feature geometry**and/or**frequency**can indicate a zone of deformation. - Using changes both of average and derivate curve, and reliability of those changes,
**probability of fault zones**can be predicted.

### FIELD DATA PROCESSING MODULE

#### CAPABILITIES:

**Angelier**or**Hoeppner**plot,**Schmidt**or**Wulff**net,**upper**or**lower**hemisphere projections are possible.**Symmetric / asymmetric**(bidirectional / unidirectional) rose diagrams with different**bin size**are available to plot**dip direction**or**strike**of data.**Contouring**data set using four different possible inputs.- Slickenside data
**correction**on two different ways. - Full
**automatic data processing**option. - Average data (e.g.
**average bedding**) calculation using regression. - Simplified data input and
**auto completition**of input database. **Paleostress inversion**using Turner (1953), Sprang (1972), Michael (1984), Angelier (1990), Fry (1999), Shan et al. (2003) and Mostafa (2005) methodologies**Bingham directional statistics**for fracture sets.**RUP**and**ANG**stress estimators display, and slickenside clustering using them.**Resolved shear**direction display on stereonet.- Stress state display on
**Mohr circle**.
