C-MASTER

A Series of Computer Programs for The Treatment of Bore Hole Records

THE PROBLEM:

Bore hole data - a significant cost item in exploration and development - is underutilized because of difficulties in:

	Producing accurate, detailed graphic logs;
	Extracting error free data from bore hole records.

Computers are made for these tasks, but some programs require extensive preprocessing and/or have only rudimentary graphics.

THE ANSWER: C-MASTER

Simple, direct log record entry that accepts:

	Latitude/longitude, UTM, or state plane coordinates
	Written rock descriptions as text or as numeric rock code Translation step converts one to the other Use colloquial expressions and still properly identify the rock types
	Measurements in feet, inches, fractions of inches; feet and decimal fractions; meters; or any combination in any log
	Measurements in rock unit thickness, cumulative down hole thickness, partial down hole thickness (core barrel runs) or any combination in any log

Rapid search and Retrieval of Stored Logs

	Singles or groups of logs
	Finds all logs having criteria such as: USGS quadrangle name State, county, or township Geographic coordinates Bed or stratigraphic position Any combination of the above (and more!)

Accurate, Detailed Graphic Log Output

	Of single or multiple logs
	Over 320 descriptive rock patterns
	Depth and elevation every inch along the margin of log
	Selectable vertical scales (i.e. 3.4 feet/inch is acceptable)
	Selectable display interval within a log, by down hole distance (meters or feet)
	Optional amounts of data in header and margins (see sample output for an example)

Detailed, Rapid Data Extraction From Logs

	Elevation and rock type at: Tagged stratigraphic positions Points at any distance above of below a tagged position Points at first occurrence of any rock type above or below a tagged position Points at any proportional distance between points
	Data for intervals between points defined above are: Thickness of interval Thickness and proportions of rock types Ratios of thickness of any specified rock to type(s) to other rock types within the interval Mean thickness of specified rock unit(s) Thickness and proportion of rock unit(s) Ratios of thickness of specified rock units to other rock units
	Output of these data to: Tables Base maps Data file for use by other programs (e.g. contouring programs)

With modest computer requirements

	Any personal computer running MS-DOSTM or PC-DOSTM Version 3.0 or higher. Versions available for mini- and maxi- computers, Windows version is in development!
	An 8088 chip is just fine, no need to have an expensive computer in the field
	At least 15 MB of disk space is recommended
	At least 512K of USER available memory
	Capability of printing 132 characters of data
	For graphic log production, a dot matrix printer or the HP® LaserJetTM series(PCL 5 compatible), or Autocad® 10 compatible

With a proven record

	Introduced in 1984
	Stress on basics and front end aspects of computer treatment of borehole data
	Suitable for and in use at very large and small organizations (currently installed at: coal companies, land companies, individual consultants, Federal agencies, and universities)
