Data Qualification Report: Borehole Straigraphic Contacts

PDF Version Also Available for Download.

Description

The data set considered here is the borehole stratigraphic contacts data (DTN: M09811MWDGFM03.000) used as input to the Geologic Framework Model. A Technical Assessment method used to evaluate these data with a two-fold approach: (1) comparison to the geophysical logs on which the contacts were, in part, based; and (2) evaluation of the data by mapping individual units using the entire data set. Qualification of the geophysical logs is being performed in a separate activity. A representative subset of the contacts data was chosen based on importance of the contact and representativeness of that contact in the total data set. ... continued below

Description

The data set considered here is the borehole stratigraphic contacts data (DTN: M09811MWDGFM03.000) used as input to the Geologic Framework Model. A Technical Assessment method used to evaluate these data with a two-fold approach: (1) comparison to the geophysical logs on which the contacts were, in part, based; and (2) evaluation of the data by mapping individual units using the entire data set. Qualification of the geophysical logs is being performed in a separate activity. A representative subset of the contacts data was chosen based on importance of the contact and representativeness of that contact in the total data set. An acceptance window was established for each contact based on the needs of the data users. Data determined to be within the acceptance window were determined to be adequate for their intended use in three-dimensional spatial modeling and were recommended to be Qualified. These methods were chosen to provide a two-pronged evaluation that examines both the origin and results of the data. The result of this evaluation is a recommendation to qualify all contacts. No data were found to lie outside the pre-determined acceptance window. Where no geophysical logs are available, data were evaluated in relation to surrounding data and by impact assessment. These data are also recommended to be qualified. The stratigraphic contact data contained in this report (Attachment VII; DTN: M00004QGFMPICK.000) are intended to replace the source data, which will remain unqualified.
