Abstract

Well servicing methods and systems are described, in one embodiment comprising a pressure containment housing fluidly connected directly to a wellhead of a wellbore, and a reel positioned inside the housing on which is spooled a communication line. One method comprises introducing the communication line into the pressurized wellbore without a well control stack, the communication line being introduced and driven into the wellbore by controlling a reel, the reel being internal to a pressurized housing removably connected directly to a wellhead of the wellbore. Fluid flow may move the communication line to a desired location in the wellbore. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It may not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b)

Dependent claims

A method of introducing a fiber optic tether into a wellbore proximate a reservoir, comprising:

performing a well operation by pumping at least a first treatment fluid through the wellbore and into the reservoir;
propelling the fiber optic tether into the wellbore without a well control stack, the fiber optic tether being propelled into the wellbore by controlling the pumping of the first treatment fluid and controlling a powered reel, the reel being internal to a pressurized housing connected to a wellhead of the wellbore;
performing a treatment operation with at least a second treatment fluid;
and
sensing downhole data related to a wellbore condition with the fiber optic tether while the fiber optic tether is propelled into the wellbore and while performing the treatment operation, the downhole data used to control the propelling of the fiber optic tether and at least a portion of the treatment operation.
