6 Wellbore Geology and Mud Log Report Data Objects (formerly Mud Log object)

For StandardWITSML v2.0

The current version of WITSML now has these main data objects related to wellbore geology (WITSML v1.4.1 had only a single mud log object):

  • Wellbore geology
  • Mud log report

In this latest version, the original v1.4.1 mud log object was divided into these two objects to better support mud logging workflows—that is, sometimes a mud log report is prepared at the same time the wellsite geologist is performing the assessment; sometimes a report is prepared for multiple assessments, after the wellsite geologist has completed several evaluations. This chapter describes the basic organization and usage of each of these objects.
