Claim Text:
1. A method for installing multiple sensors comprising pressure transducers with pressure block housings, Distributed Temperature Sensing (DTS) sensors, and Distributed Acoustic Sensing (DAS) sensors in unrolled coiled tubing, comprising: laying the unrolled coiled tubing, having a tophole end and a downhole end, horizontally onto the ground; after laying, positioning multiple spools of Fiber in Metal Tubing (FIMT) at the tophole end of the coiled tubing, staggered by a distance from the tophole end that each pressure transducer, DTS or DAS sensor will be positioned in the unrolled coiled tubing; after positioning the multiple spools of FIMT at the tophole end, attaching each of the to be deployed pressure block housings, DTS sensors, and DAS sensors to the end of one of the multiple FIMTs, so that each pressure block housing, DTS Sensor and DAS sensor is attached to one spool of the multiple spools of FIMT; positioning multiple spools of pull cables, each driven by a separate winch, at the downhole end of the unrolled coiled tubing, with one pull cable spool with one pull cable for each FIMT spool at the top end; blowing a line through the unrolled coiled tubing from the tophole end to the downhole end; then attaching each of the pull cables from the multiple spools of pull cables on the downhole end to the line and pulling on the line using a winch at the tophole end to pull the pull cables to the tophole end; then connecting each pull cable now on the tophole end to one of the pressure block housings, DTS sensors, and DAS sensors so that each pressure block housing, DTS sensor, and DAS sensor is connected to one pull cable spool from the downhole end; and then using the multiple spools of pull cables on the downhole end, each pull cable pulled by a separate winch, to pull the assembled pressure block housings, DTS sensors, and DAS sensors into the unrolled coiled tubing, creating a downhole sensor system in the unrolled coiled tubing; wherein as each pressure block housing enters the unrolled coiled tubing the FIMTs and pull cables are positioned to fit into grooves in the pressure block housing as they pass into the unrolled coiled tubing.
