GEOCAD : geological computer aided description software for sedimentary rocks

الملخص EN

GEOCAD is an interactive IBM PC and compatible software for geological de- scription and reporting of sedimentary rocks.

The system consists of one control procedure and 37 transaction procedures for the complete sequence of standard stratigraphic description.

It follows two different paths for detrital and carbonate sediments.

GEOCAD is a useful tool for geologists who are describing rock characteristics by using microscopes and computerized references of a description sequence.

The system was developed in-house using local exper- tises and dBASE IV database management system capabilities.

Rock type, mineralogical composition, texture, fossil, depositional and diagenetic environ- ments.

and other parameters are recorded by selecting given options from the computer sc- reen.

These codes are validated against a built-in dictionary, and a complete translation of the description is stored in the database.

There are over 600 description codes which can be en- tered with commonly accepted abbreviations into the dictionary.

An abbreviated or a full de- scription text can be obtained through any printer.

Identification of the sedimentary rocks in this system is based on standard terminology with full description sequence, which replaces most referrals to reference manuals during the description, and works as a reminder as well.

The numerous sorting, selecting, and grouping combinations may be established for single and/or multiwell studies.

The system is developed with menu driven windows, so it is user friendly, eliminating the necessity for previous computer experience.
