Basics of Logging


If you are looking to get information about your borehole or well, from formation characteristics to fluid properties, you will need to log it. Logging is the practice of lowering down a set of measurement probes into your well to measure the properties you need. To get the measurement probes in the hole, you will need an electrical logging cable and a winch. To supply power and to read the data from the probes, you will need a surface electronic unit, like the Geovista ‘logger’. All this information can then be processed using software on your PC.

 Why should I log my boreholes?

There are numerous reasons why you should get as much information from your boreholes as possible. These could include:

  1.  Getting as much information about your well as possible.
  2.  Make better decisions. Design your boreholes, re-design your well, identify the reservoir, locate the payzone,          develop the well, locate a problem, understand your production, evaluate your mineral, plan your drilling    activity.
  3.  Borehole investigation.
  4.  Depth correlate and confirm your surface geophysical surveys.
  5.  Exploration and location of your objective (water, mineral….)
  6.  Logging is fast and provides continuous and reliable high quality data.
  7.  Observe changes over time.
  8.  Important part in mineral identification, geotechnical and environmental evaluation.
  9.  Making better decisions – save costs.
