ABSTRACT:

The paper deals with the first unconventional well testing performed in Algeria, in February 2008. As in several other countries, the Algerian law does not allow flaring and requires storage and transport of produced hydrocarbons to the closest facility. The injection test technology was chosen among others as a suitable alternative to well testing for a field application successfully carried out in the Berkin Basin. The test was carried out in an oil bearing formation, and the injected fluid was diesel. The advantages of the injection test are mainly relevant from an HSE standpoint, but also for reducing the testing equipment and costs. ENI E&P has gained some experience on injection testing applications in the past 2 years. Once more the technology proved to be an effective alternative to conventional well testing, allowing calculation of the main well/formation parameters in a relatively straightforward manner
