Abstract: Estimating parameters of interest of a formation, including density, porosity, and fluid saturation. Methods relate to gamma ray energy spectra calibration for a radiation detector including generating a calibration radiation spectrum using measurements of radiation with the detector in a time interval wherein the radiation comprises predominantly gamma rays emitted by decay of radionuclides produced by neutron activation reactions resulting from neutron irradiation, the time interval following a prior time interval corresponding to thermal neutrons produced from the irradiation; making at least one other radiation measurement with the detector outside the time interval; and producing a calibrated radiation measurement from the at least one other radiation measurement using the calibration radiation spectrum. The measurements may be taken in the time interval by conveying the radiation detector in the borehole at high speed and using a background gate of the detector.

Abstract: A method of estimating properties of wellbore cement by penetrating the cement, and monitoring the amount of energy or power required for penetrating the cement. Penetrators include a drill bit that bores into the cement, and probes or pins that are forced into the cement. The energy or power monitored can be current and/or voltage supplied to a motor that drives the drill bit or probe. Comparing the monitored energy or power with that required to penetrate a reference cement sample of known properties can yield information about the cement being sampled. When the wellbore is lined with multiple coaxially disposed strings of casing with cement between adjacent strings and on the outer surface of the outer string; the method further includes obtaining core samples from portions of each string, each layer of cement, and formation adjacent the wellbore.

Abstract: A downhole device for use in a wellbore that has sensors for monitoring flow rates and fluid properties of fluid flowing in the wellbore. The sensors are disposed adjacent one another so that the properties of the fluid monitored by the sensors are substantially the same. The sensor for monitoring flow rate is a flow meter optionally equipped with rotatable members that are affixed to a rotatable base member. The members are positioned in a path of the flowing fluid which rotates the members and base member; the fluid flow rate is estimated based on a measured rotational rate of the base member. Properties estimated by the fluid property sensor include viscosity and density. The fluid property sensor can include a resonating member disposed in the fluid flow path, by measuring the damping of the fluid across the resonating member, the fluid density and viscosity can be estimated.

Abstract: A flowmeter for use in a borehole that includes a transmitter and receivers spaced axially away from the transmitter. Energizing the transmitter creates electrical field lines that extend between the transmitter and the receivers, and that pass through fluid flowing past the flowmeter. The magnitude of the electrical field lines at each of the receivers is measured, and varies in response to different types of fluid flowing past the flowmeter, and changes in phase of the fluid. Example transmitters and receivers include coils and electrodes. The transmitters and receivers can define elongate arrays, where the arrays are arranged parallel to, oblique, or perpendicular to an axis of the borehole. Multiple array orientations provide a radial cross sectional image of the flowing fluid. Thus not only can multi-phase flow be detected, but the type of flow regime can be identified.

Abstract: A flowmeter for use in a wellbore that has vane assemblies that deploy from a rotating segment. The vane assemblies project a variable distance away from the rotating segment, so that the flowmeter adjust to varying flow conditions. The variable distance of the vane assemblies also allows use of the flowmeter in different sized wellbores. An example flowmeter includes vane assemblies of varying length that are selectively deployed depending on operating conditions. Other vane assemblies have vane elements with a pitch that varies in response to wellbore and fluid flow operating parameters.

Abstract: Methods, systems, devices, and products for well logging using a logging tool in a borehole in an earth formation. Methods include conveying the logging tool in the borehole on a carrier; taking acoustic well logging measurements with the logging tool including generating a multitone acoustic beam from at least one transmitter on the tool, the beam comprising a high frequency signal modulated by a low frequency envelope, the high frequency signal including a first subsignal at a first frequency and a second subsignal at a second frequency, and generating measurement information at at least one acoustic receiver on the logging tool in response to a plurality of acoustic reflections of the acoustic beam from at least one volume of interest in the formation; and estimating a property of the volume of interest using the measurement information.
