摘要： A method of downhole characterization of formation fluids is provided. The method includes: estimating a rough value of the bubble point pressure of the formation fluids; depressurizing the formation fluids at a first speed to a certain pressure which is a predetermined value higher than the estimated rough value while the formation fluids are isolated in a portion of the flowline; and depressurizing the isolated fluids at a second speed which is slower than the first speed in order to measure a precise value of the bubble point pressure.

摘要： For various reasons it may be desirable to change the way a sonde is programmed to behave and respond to the data it receives and operates on, and at present each time this must be done it has been necessary to lift the sonde out of the borehole and then disassemble it to permit the removal of the old ROM and its replacement with a new ROM storing the new program. The operability and efficiency of such an arrangement is poor. To deal with this, the present invention proposes that the sonde also includes: signal processing means for processing a sampled detection signal according to a predetermined signal processing program; first memory means for storing that signal processing program; and second memory means storing a writing program for writing the signal processing program in the first memory means according to a command from the ground surface processing apparatus. In this way the sonde's program can be updated from the surface simply by downloading the new program into it, and without the need to bring the sonde up to the surface.
