P&ID


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.

Importance of P&ID

To standardize process of best practices Gives exactly what to replicate on the well test area /field site

2 Common Undesirable Events in WT Process System

Over pressure Leak


Causes of over pressure

Input > outputRestrictionOver flow or gas blow-byThermal expansion


Effects of Over Pressure and Detectable Abnormal Condition

Sudden rupture Confusion and panic Leak of HC


.



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.
