A system and method for deploying and retrieving a welltracker in a well include coupling a Christmas tree to the well, coupling a sensor deployment capsule to the Christmas tree, inserting and storing the welltracker into the cylindrical housing via a removable cap screw, and deploying the welltracker through the Christmas tree and into the well. The system and method further include dissolving a dissolvable weight on the welltracker at a well fluid pressure threshold, retrieving the welltracker to the cylindrical housing, bleeding off trapped pressure in the cylindrical housing from retrieval, via the drain valve, through the pressure transfer line, and controlling pressure in the sensor deployment capsule via the pressure gauge. The sensor deployment capsule includes a cylindrical housing including a removable cap screw, a drain valve coupled to the cylindrical housing and a pressure transfer line, and a pressure gauge coupled to the removable cap screw.

Advanced welltracker deployment capsule for oil and gas wells

A system performs rig-less well intervention at wellbore. The system includes a wellhead provided at a wellbore and a flow regulation device that selectively admits a flow of formation fluid between the wellhead and the blowout preventer. The system further includes a shifting tool mechanism configured to latch on and engage the flow regulation device to selectively control the flow of formation fluid between the wellhead and the blowout preventer. A related method includes connecting a rig-less well intervention unit to a blowout preventer and connecting the blowout preventer to a Christmas tree. The blowout preventer comprises a shifting tool mechanism and the Christmas tree comprises a flow regulation device. The method further includes lowering the shifting tool mechanism to a predetermined depth, engaging the shifting tool mechanism with the flow regulation device and activating the shifting tool mechanism to actuate the flow regulation device to an open position.
