Abstract: Techniques for determining depths of provenance of drill cuttings contained in a drilling fluid received from a wellbore. The drilling fluid contains drill cuttings of different sizes that arrive at surface at different times, and the drill cuttings originate from different formation layers at different depths along the wellbore. Such techniques may include extracting samples of drill cuttings from the drilling fluid and repeating this step as necessary to provide samples of drill cuttings that arrive at surface at different recorded times; characterizing one or more formation attributes associated with the drill cuttings; and for each formation attribute, estimating a distribution of formation attribute characterization versus depth of provenance.

Abstract: Methods of and systems for determining depths of provenance of drill cuttings contained in a drilling fluid received from a wellbore, the drilling fluid containing drill cuttings of different sizes that arrive at surface at different recorded times, the drill cuttings originating from different formation layers at different depth along the wellbore. Such methods, for example, may include extracting samples of drill cuttings from the drilling fluid, wherein the drill cuttings in the samples are smaller than a predetermined threshold and repeating this step as necessary to provide samples of drill cuttings that arrive at surface at different recorded times; characterizing drill cuttings in the samples, comprising characterizing one or more formation attributes associated with the drill cuttings; and for each formation attribute estimating a distribution of formation attribute characterization versus depth of provenance, comprising defining a hydrodynamic transport of the characterized drill cuttings within the drilling fluid, including an effect of diffusion and dispersion on the hydrodynamic transport.

Abstract: A method and system for acoustic monitoring using a fiber optic cable. The optical fiber is used as a distributed interferometer that may be used to monitor activity, such as activity with respect to a conduit, wellbore or reservoir. The distributed interferometric monitoring provides for accurate detection of acoustic occurrences along the fiber optic cable and these acoustic occurrences may include fluid flow in a pipeline or wellbore, processes taking place in a wellbore or pipeline, fracturing, gravel packing, production logging and/or the like.

Abstract: Monitoring one or more items of equipment associated with a borehole or other conduit. A sensor system includes a vibration sensor for sensing vibrations at one or more sensor locations associated with one or more items of the equipment and/or the borehole or other conduit. A processing system processes the sensor information to determine a characteristic of the operation of the one or more items of equipment and/or the borehole or other conduit.

Abstract: A method for compensating for changes in a property of water in a multiphase fluid during analysis of the multiphase fluid is provided. In one embodiment, the method includes providing a multiphase flow meter system configured to emit and detect nuclear radiation, to emit and detect microwave radiation, and to analyze a received multiphase fluid. The method can also include measuring a temperature and a microwave complex permittivity of the multiphase fluid. Further, the method includes compensating for changes in the property of water in the multiphase fluid during analysis of the multiphase fluid by using an empirical transformation between the fluid temperatures, microwave complex permittivities and nuclear mass attenuation coefficients for mixtures of different waters expected to be produced and received by the multiphase flow meter system. Additional systems, devices, and methods are also disclosed.
