摘要： Methods for characterizing heavy oils are described. The methods involve extracting one or more asphaltenes from the heavy oil and measuring the viscosity of the heavy oil. The extracted asphaltenes are characterized and correlated to the viscosity of the heavy oil. By identifying the asphaltenes that are responsible for the high viscosity in the heavy oil, solvent systems can be developed for reducing the viscosity of the heavy oil.

摘要： A technique facilitates the detection of moisture. The technique utilizes distributed sensor lines deployed along an insulated vessel, such as an insulated pipe. The sensor lines are used to measure temperature and to determine a differential temperature across the insulation between the sensor lines. Changes in the differential temperature can be detected, and those changes are used to determine whether moisture has intruded into a specific region of the insulation.

摘要： A method for propagating short optical pulses comprises constructing a composite pulse (22) comprising a probe pulse (10) flanked by a pair of guard pulses (16, 18) of different wavelength from the probe pulse. These pulses have respective temporal delays so that the composite pulse has a central portion in which the intensity is substantially constant with time. This protects the probe pulse from self-phase modulation (SPM) during propagation of the composite pulse through an optical fibre; only the external edges of the guard pulses undergo SPM. After propagation, the guard pulses are filtered out, leaving an undistorted probe pulse for detection. In some embodiments, the composite pulse contains a plurality of probe pulses, which may have different wavelengths. Various apparatus can be used for generation of the composite pulse.

摘要： A distributed temperature sensor is deployed in a wellbore and is functionally connected to a processor. The processor receives the data from the distributed temperature sensor and automatically processes the data to highlight valuable information to the user relating to the relevant well, completion, or reservoir. In one embodiment, the distributed temperature sensor and processor are utilized in a well containing a gas-lift system, wherein the processor highlights valuable information to the user pertaining to the gas-lift system. A well model enabled by the processor enables the determination of a produced fluid flow rate in the well having a gas lift system. Temperatures are measured within the well to obtain a temperature profile, and this profile is processed according to the well model. The well model relates thermal characteristics, e.g. thermal decay and/or amplitude of a thermal discontinuity at an injection point, to flow rate. The flow rate determined from the thermal characteristics is used to optimize production from the well.

摘要： A method of obtaining a distributed measurement comprises deploying an optical fibre in a measurement region of interest, and launching into it a first optical signal at a first wavelength λ 0 and a high power level, a second optical signal at a second wavelength λ -1 , and a third optical signal at the first wavelength λ 0 and a low power level. These optical signals generate backscattered light at the second wavelength λ -1 arising from Raman scattering of the first optical signal which is indicative of a parameter to be measured, at the first wavelength λ 0 arising from Rayleigh scattering of the first optical signal, at the second wavelength λ -1 arising from Rayleigh scattering of the second optical signal, and at the first wavelength λ 0 arising from Rayleigh scattering of the third optical signal. The backscattered light is detected to generate four output signals, and a final output signal is derived by normalising the Raman scattering signal to a function derived from the three Rayleigh scattering signals, which removes the effects of wavelength-dependent and nonlinear loss.
