==Wellsite data package==
==Wellsite data package==
A data package should be prepared for use on the wellsite containing all of the data needed for correlation and evaluation. This includes maps, offset well logs, the well prognosis, and any other data that the geologist believes may be useful. Only copies (not the originals) of these data should be taken to the field.
