APR DST Drain valve Drill stem testing tools

Downhole Testing Equipment

The well testing and sampling operation is typically accomplished with an assortment of test tools. The basic downhole test tools required for a well test include:

• Reversing valve

• Tester valve

• Samplers

• Gauges (pressure and temperature recorders)

• Packer

• Tubing conveyed perforating guns

To determine the makeup of a test string, a test objective must be established and well defined. If the objective of the test is to perforate underbalanced and then test, only tools with a full opening should be used. A rule of thumb to observe when selecting the components of a test string is to keep the string as simple as possible. Avoid redundancy unless there is a real benefit to be gained. A variety of techniques and arrangements

of test tools are used to handle diverse types of tests—from openhole to high-pressure/hightemperature(HPHT) and underbalanced to name a few.
