Abstract
A method for installing multiple fiber optic cables in coiled tubing in oil and gas operations.
Claims16
A method for installing multiple pressure transducers, DTS, DAS and/or other downhole sensor systems in coiled tubing, comprising:
- a. laying extended coiled tubing horizontal to the ground;
- b. positioning multiple spools of FIMT at the tophole end, staggered by the distance their related pressure housings will be installed in the tubing;
- c. splicing each to be deployed pressure housings and DTS/DAS systems to the end of one of the multiple FIMT spools
- d. positioning multiple spools of pull cables, each driven by a separate winch, at the tophole end;
- e. blowing a line through the tubing from the tophole end to the downhole end;
- f. attaching all of the pull cables to the line and pulling on the line using a winch to pull the pull cables to the tophole end;
- g. connecting each pull cable to one of the pressure housings or DTS/DAS FIMT or tubes;
- h. using the multiple spools of pull cables, each pulled by a separate winch, to pull the assembled pressure housings and DTS/DAS systems into the tubing;
- i. wherein as each pressure housing enters the tubing the FIMT's and pull cables are positioned to fit into grooves in the pressure housing as they pass into the tubing.
6 more elements
A pressure housing for use in installing multiple pressure transducers, DTS, DAS and/or other downhole sensor systems in coiled tubing comprising:
- a. a threaded hole on the downhole end to accommodate a pull fixture;
- b. multiple grooves on the exterior surface acting as passageways for FIMTs and pull cables.
