CCS Input File Specification

TPHs use the single comma separated value (CSV) file format specified in this section to participate in multilateral compression. TPHs specify existing positions to be considered for compression, and cost and risk constraints of compression portfolios they are willing to accept from the compression process. The certification process for multilateral compression validates TPH ability to construct properly structured input files with cost and risk constraints.

The CSV file format specification that follows comprises both numeric and non-numeric data. Embedded whitespace is not permitted at any location within an input record. Certain fields contain required null values represented by consecutive commas. Numeric precision of numeric fields is significant and is presented in detail below.

Note on precision - TPHs wishing to exactly replicate reported constraint values computed by the system and represented in the detail output file presented in Compression Portfolio Detail File must provide floating point numeric values to the precision as underlined below. If values are provided to higher precision, they will be rounded by the system and as a result, due to floating point number representation differences between platforms, TPHs might not be able to exactly replicate aggregated constraint values (though discrepancies will be very small).
