Methods and systems for conveying a WFT via drill pipe within a wellbore penetrating a subterranean formation and setting two packers of the WFT on opposite sides of a zone of interest of the formation, thereby isolating an interval of an annulus between the WFT and a wall of the wellbore. DTT of the formation is then performed by operating two WFT pumps of the WFT to pump fluid from the formation via the isolated interval, through the WFT, and out of the WFT to the wellbore, while operating mud pumps to pump drilling mud into the wellbore and thereby convey a mixture of the drilling mud and the pumped formation fluid through the annulus to a mud gas separator. Gas from the mud gas separator is used to measure a surface production rate of the formation fluid.

Combination of a surface well testing facility and a cable formation tester with an active circulation system for obtaining inflow and measuring formation fluid parameters on the surface
