    摘要: A method of treating a subterranean formation penetrated by a wellbore includes preparing a treatment fluid with shear thinning, non-monotonic rheological properties, injecting the treatment fluid into the subterranean formation, and inducing shear rate softening phase transition in the treatment fluid. The non-monotonic rheology properties can be such that in the relationship between shear stress (σ) versus strain rate ({dot over (γ)}), where {dot over (γ)}1

    摘要: 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.
