Methods, systems, devices, and products for taking multi-component induction tool measurements of a three-dimensional space from an interior of a plurality of nested tubulars in a borehole in an earth formation and estimating the property for each of the at least two tubulars using the multi-component induction tool measurements. The multicomponent induction tool measurements may be responsive to a property corresponding to at least two conductive tubulars of the plurality of nested tubular. Taking multi-component induction tool measurements may include taking three-dimensional low-frequency sinusoidal frequency domain waveform resistivity measurements and taking three-dimensional transient EM measurements with the multi-component induction tool.

A pipe casing inspection system that combines sensor information including magnetic flux leakage from High Resolution Vertilog Tools (HRVTM) and Multi Finger Caliper (MFC) measurements. This data is used to create a model to calculate a number of metrics to gauge when the pipe will burst based on pipe corrosion, degradation, defects, damages, dents, perforations, geometry deformation, and others. The measurements can occur simultaneously and are jointly processed and interpreted to determine when the pipe will not be serviceable. Also, the measurements are taken using 3-D Electromagnetic MEM's sensor array distributed azimuthally, axially, and longitudinally.

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.

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.

G01V 7/06

A method of estimating one or both of compaction or subsidence of a subterranean formation with gravity measurements. The free air gradient at surface is measured and compared with gravity measured in a borehole that intersects the formation. At a later point in time, values for gravity are re-measured, differences between the measured values at the initial point in time, and the later point in time are estimated. The differences are used to estimate the compaction or subsidence. A gravimeter can be used for measuring gravity, markers in the formation can be used in conjunction with the gravimeter.

G01F 1/58

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.

E21B 47/10

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.

An apparatus for estimating a fraction of each component of a fluid of interest flowing in a cased borehole and a property of the fluid includes an acoustic waveguide sensor having a waveguide configured to guide an acoustic signal along a waveguide path and an array of acoustic transducers coupled to the waveguide for transmitting and receiving an acoustic signal, the acoustic waveguide sensor being configured to transmit and receive a compression-wave acoustic signal that is reflected off of the casing and transmit and receive a shear-wave acoustic signal that propagates along the path. A controller is coupled to the waveguide sensor and configured to perform a compression-wave acoustic measurement on the fluid using the acoustic waveguide sensor in order to estimate the fraction of each component of the fluid and to perform a shear-wave acoustic measurement in order to estimate the property of the fluid.
