What is a P&ID?
It is detailed schematic that we use to replicate a well test
setup
It is based on API RP 14C
A P&ID is a diagram in the process industry which shows the
piping of the process together with the installed equipment
and instrumentation.

Causes of LeaksGlobal Training Course
Corrosion Erosion Mechanical failure Excess temperature Rupture from over pressure Accidental damage from external forces

Effect of Leak and Detectable Abnormal Condition
Release of HC to environment
The detectable abnormal conditions are low pressure, backflow, low level.
