Workshops - anywhere in the world
($1000 plus my moderate expenses)


Petr Vavruch has presented his unique two-day workshop many times.

Three workshops in South Africa in 2018, positively evaluated by all participants, were held in Benoni, East Rand, Gauteng, in Cape Town and in Newlands, Cape Town.

To discuss the two-day workshop or anything else click here to write to me.

The workshop is based on the book but is fully illustrated and explained. It is highly interactive and includes also basics of equipment monitoring, oil sampling, laboratory test results, contamination and related subjects.
