Conventional well testing usually involves production of reservoir fluid at the surface. For newly completed wells, surface equipment to store reservoir fluid may not be present, so the fluid may be discharged and flared. Discharge of such fluids can be an environmental hazard.

In this study, testing of wells without surface production is investigated. Three possible testing methods are suggested and compared.

Three tests suggested are (1) closed chamber test, (2) controlled reinjection of reservoir fluid, and (3) modification of closed chamber test for longer duration. The radii of investigation for these tests were studied. The modified test and controlled reinjection tests are shown to have the large radius of investigation. A composite reservoir model was used to test the investigation radius.
