摘要: A method for estimating one or more interval densities in a subterranean wellbore includes acquiring first and second axially spaced pressure measurements in the wellbore. The pressure measurements may then be processed to obtain an interval density of drilling fluid between the measurement locations. A tool string including a large number of axially spaced pressure sensors (e.g., four or more or even six or more) electronically coupled with a surface processor via wired drill pipe may be used to obtain a plurality of interval densities corresponding to various wellbore intervals.

摘要: The present invention provides methods and systems for making measurements associated with a rock formation including a main borehole, a microborehole extending from the main borehole into the rock formation, and one or more sensing devices positioned and arranged to make a measurement at measurement zones being located in the microborehole. A packer can also be installed in the microborehole dimensioned and arranged to hydraulically isolate the measurement zones from conditions present in other parts of the microborehole and/or main borehole. Methods and systems are also provided for taking fluid samples and injecting fluid tracers in a microborehole.

摘要: A method of sampling a multi-phase fluid stream is provided which comprises the steps of: sampling, with a sampling probe, a portion of the fluid stream; measuring the flow rate of said sampled portion; and measuring, independently of the sampling step, the total flow rate of the fluid stream, wherein the flow rate of the sampled portion is controlled according to the ratio of the flow rate of the sampled portion to the flow rate of the fluid stream, in order to obtain substantially isokinetic sampling of the fluid stream. The method may provide isokinetic sampling to an accuracy of 5% or less and preferably only samples a small portion of the fluid stream. The method has particular application for high rate condensate gas wells. A corresponding sampling system is provided which has particular application in the sampling of streams from well-heads. A flow conditioner for use with sampling methods and systems is also provided, the flow conditioner being a pipe section including: a swirl inducing section; a flow straightener, and an orifice plate.

摘要: A method for a hydraulic model for subterranean drilling fluids includes acquiring first and second axially spaced temperature and pressure measurements in the wellbore. The pressure measurements may be processed to obtain an interval density of drilling fluid between the measurement locations. A tool string including a large number of axially spaced pressure sensors (e.g., four or more or even six or more) electronically coupled with a surface processor via wired drill pipe may be used to obtain a plurality of interval densities corresponding to various wellbore intervals. The interval density(ies) may be processed in combination with the temperature and pressure measurements to compute one or more unknown coefficients of the hydraulic model.
