"Ada" Pressure Test Procedures

Testing a Well Without Tubing

Figure 1 
Static conditions at the start of the test

Figure 2 
Applying gas test pressure, excess gas 
pressure bleads away into the formation 
as fluid level drops below the perforations

Figure 3 
Mechanical integrity is demonstrated 
by a stabilzed test pressure equal to 
the calculated value

Figure 4 
A leak is indicated by test pressure 
being less than the calculated value

Testing a Well with Tubing but No Packer

Static conditions at the start of the test

Figure 2

pressure bleads away into the formation 
as fluid level drops below the perforations

Mechanical integrity is demonstrated 
by a stabilzed test pressure 
equal to the calculated value

Figure 4 
A leak is indicated by test pressure 
being less than the calculated value

Testing Well with Tubing and Packer with Dual Production/Injection Completion

Figure 1 
Static conditions at the start of the 
annulus test

Figure 2 
Applying gas test pressure, excess gas 
pressure bleads away into the formation 
as fluid level drops below the perforations

Figure 3 
Mechanical integrity is demonstrated by a stabilzed test pressure equal to the calculated value a leak is indicated by test pressure being less than the calculated value

Figure 4
Static conditions at the start of the 
tubing and packer test

Figure 5 
Applying gas test pressure, the fluid level in the tubing is depressed past the packer, excess gas pressure bleads away into the formation as fluid level drops below the perforations

Figure 6 
A leak is indicated by test pressure being 
less than the calculated value.
