WITSML Log - Curve Information The order of the data should correspond to the 'direction'. The actual data corresponding to the curves defined in the LOGCURVEINFO element. A comma delimited list of data values with one value for each curve on the log (e.g., "xxx,yyy, zzz"). For array curves, the value of the array curve will be a space delimited list of values that are contained within the commas that delimit the value for that curve (e.g., "xxx,aa bb cc,zzz"). This essentially represents one row of a table where the curve mnemonics represent the column headings.
