Optical coiled tubing log assembly

A logging tool comprising:

• well profile generating equipment;
• a downhole power source coupled to said equipment;
• and
• an interface coupled to said equipment for acquiring optical data from a fiber optic line disposed in an interior portion of coiled tubing, the optical data being utilized to direct said equipment, the interface further utilized to communicate data from the equipment to a surface of an oilfield, the interior portion of the coiled tubing substantially un-occluded by the fiber optic line such that a well treatment application may be performed.

An assembly comprising:

• coiled tubing deployable from an oilfield surface adjacent a well defining an single channel therein;
• an interventional treatment device coupled to said coiled tubing for performing an interventional application relative to the well;
• and
• a logging tool coupled to said coiled tubing and configured to acquire well information for establishing a profile thereof;
• and
• a fiber optic line disposed within the channel of said coiled tubing in a substantially un-occlusive manner and coupled to said logging tool.

A method of logging a well to establish a profile thereof, the method comprising:

• deploying a fiber optic tether through an interior of a coiled tubing from an oilfield surface adjacent the well the fiber optic tether having a degree of slack relative to the coiled tubing;
• coupling the coiled tubing and the fiber optic tether to a logging tool and a treatment tool for advancement into the well, the fiber optic tether providing sufficient volume within the coiled tubing interior to allow fluid flow therethrough to perform a treatment application;
• and
• performing at least one logging application with the logging tool.
