Abstract
Demand to replace conventional test with flaring to surface with zero emission test is becoming increasingly important in the light of environmental protection and CO2 emission reduction. Furthermore, flaring permits are getting more and more difficult to obtain, and are going to be completely banned very soon. In this work we will demonstrate how injection/fall-off test could be improved in terms of execution by tailoring to specific test objectives as well as in interpretation and integration. To improve permeability and skin allocation among layers in a coherent and robust interplay, several methods have been investigated and improved testing procedure and test interpretation and integration in terms of maximizing the Value of Information have been proposed. With improvements in injection well testing procedure and advanced interpretation and integration, injection tests could become the tests for the 21st century, where emission of greenhouse and toxic gasses will be drastically reduced or not permitted at all.
