Well Logs

Listed in the following pages are the logs of 45 wells and test holes in Morton county, including 11 test holes drilled by the State and Federal Geological Surveys (1-11), 11 water wells (12-22), and 23 gas test wells (23-45). The locations of the test holes are shown in figure 2 and of the wells in plate 2.

About three-fourths of the logs were made by well drillers. Many of the drillers' rock names have been changed to conform with geologic terminology. "Gyp" or "gyp rock" has been interpreted to mean caliche, and "soapstone" has been changed to shale or clay. The term "sand rock" is used by drillers to describe a rock that is so well consolidated that no casing is needed to prevent caving. Much of the Ogallala formation has been logged as clay, but in those wells from which cuttings were available for study it was found that most of the so-called clay was silt.
