Well Test Interpretation, in the ETS Testing Services is the state of the art in well test interpretation. It emphasizes the need for a controlled down hole environment and high-performance gauges, both of which have made well testing a powerful reservoir description tool.

It covers descriptive and reservoir well testing, gas well testing, and the application of simultaneously recorded down hole rate and pressure measurements to well testing. Testing techniques are covered for the following:

• layered reservoirs and horizontal wells.
• low-energy wells sucker-rod pumping wells.
• multiple wells.
• vertical interference.
• testing combined with perforation
