Several techniques are available to help the operator decide whether to
complete the well. One of the simplest is looking at the cuttings the drilling mud
carries from the bottom of the hole (fig. 176). A geologist can test the cuttings to
determine whether they contain hydrocarbons. The mud logger, using various kinds
of detection equipment, can also spot hydrocarbons in the drilling mud. An operator
probably would not decide to complete or abandon a well using only information
from cuttings and mud returns. Careful examination of them, however, can indicate
whether the well is likely to produce.
Well logging is a widely used evaluation technique. Many kinds of logging
tool are available. Some measure and record natural and induced nuclear, or

radioactive attributes of a rock. Others measure and record the way in which
formations respond to electric current. Another log measures and records the speed
with which sound travels through a formation. These are only a few of many logs
available to the operator. By interpreting the recordings, or logs, the operator can
usually tell if the well will be a producer.
