    摘要: A method for determining oil viscosity and continuous gas-oil-ratio (GOR) from nuclear magnetic resonance logs (NMR). The method includes obtaining a set of NMR data of a portion of the subterranean formation from inside the wellbore without acquiring formation fluid sample; isolating a quantitative reservoir fluid information associated with oil from oil based mud (OBM) using radial profiling of the set of NMR data, wherein the OBM is used for extracting fluid from the underground reservoir; determining GOR related information associated with the portion of the subterranean formation from the quantitative reservoir fluid information associated with oil, wherein the GOR related information is determined based on a predetermined model; and performing operations for the oilfield based on the GOR related information.

    摘要: A system to determine the mixture of fluids in the deviated section of a wellbore comprising at least one distributed temperature sensor adapted to measure the temperature profile along at least two levels of a vertical axis of the deviated section. Each distributed temperature sensor can be a fiber optic line functionally connected to a light source that may utilize optical time domain reflectometry to measure the temperature profile along the length of the fiber line. The temperature profiles at different positions along the vertical axis of the deviated wellbore enables the determination of the cross-sectional distribution of fluids flowing along the deviated section. Together with the fluid velocity of each of the fluids flowing along the deviated section, the cross-sectional fluid distribution enables the calculation of the flow rates of each of the fluids. The system may also be used in conjunction with a pipeline, such as a subsea pipeline, to determine the flow rates of fluids flowing therethrough.

    摘要: A method and apparatus for acoustically inspecting a tubular member is presented. In particular a method for inspecting coiled tubing using ultrasound is presented. The method includes contacting a tubular with a coupling material, transmitting an acoustic signal, receiving a returned acoustic signal and then releasing the contact of the coupling material with the tubular. The method has particular application for determining the wall thickness of coiled tubing as it is being unreeled into a borehole or wound on coiled tubing reel.

    摘要: A formation treatment tool assembly is conveyed within a well casing by a tubing string and has a housing defining treatment fluid supply and discharge passages and a fluid injection port through which treatment fluid is directed from the supply passage into a packer isolated casing interval and a fluid inlet port permitting flow from the isolated casing interval to the fluid discharge passage. Spaced straddle packer elements of the tool are energized to establish sealing engagement with the well casing and define an isolated casing interval and are de-energized to retract from sealing engagement with the well casing and permit tubing conveyance. A dump valve connected with the tool housing is opened to permit flow of treatment fluid from the isolated casing interval through the treatment fluid discharge passage and is closed to confine treatment fluid to the isolated casing interval. A hydraulic or mechanically actuated tubing isolation valve is selectively closed to isolate the tubing string from casing or formation pressure and permit tool conveyance while maximizing the service life of the tubing string and to accommodate overpressured and underbalanced reservoir conditions.
