Abstract (en)
The present invention relates to a downhole deployment system (1) for ejecting a tracer (39) and/or taking a fluid sample of a fluid in a lateral (2) in a well (3). The system comprises a stroking tool (4) comprising a shaft (5), the stroking tool providing a reciprocating movement of the shaft, and a deployment tool (6). The deployment tool comprises a tool body (7), a tool inlet (8), a tool outlet (35), a deployment chamber (9) arranged in the tool body, a piston (10) dividing the deployment chamber into a first deployment chamber part (11) and a second deployment chamber part (12), the first deployment chamber part being in fluid communication with the tool outlet and the second deployment chamber part being in fluid communication with the tool inlet, and a piston rod (14) connected to the piston and driven by the shaft for moving the piston from a first position to a second position, thereby decreasing the first deployment chamber part and increasing the second deployment chamber part, in order to eject the tracer from the first deployment chamber part or collect the fluid sample through the tool inlet. The present invention furthermore relates to a production optimising method using the downhole deployment system.
