Abstract: An intelligent completion module comprises a flowmeter that uses one or more electromagnetic acoustic transducer (EMAT) sensors and a flow control valve. The flow rate and the speed of sound in the production fluid from a production zone is measured and used to make reservoir management decisions. The flowmeter comprises at least two EMAT rings, comprising one or more EMAT sensors in a circular distribution which can be used in propagation or pulse-echo modes. In a segregated flow regime, a single EMAT sensor in pulse-echo mode is used to measure holdups of fluid components.

Abstract: A downhole tool to make one or more downhole measurements of laser-induced vaporization and/or pyrolysis of hydrocarbons is provided and disposed at a desired location within a wellbore. A tool head of the downhole tool is brought into sealing engagement with the wellbore wall. The fluid within an interior region enclosed by the tool head and the wellbore wall is evacuated and a measurement spot is irradiated with a laser to generate volatile hydrocarbons and/or pyrolytic hydrocarbons. Measurements are made on the volatile hydrocarbons and/or pyrolytic hydrocarbons and one or more formation properties are inferred based on the measurements. A low level of laser radiation intensity, irradiating some or all of the wellbore wall enclosing the interior region, may be used to prevent measurement contamination, and both medium power and high power levels of laser radiation may be used to first vaporize and then pyrolyze the hydrocarbons.

Abstract: A mineralogy composition of a formation of interest is determined using core samples or downhole measurements. A dry permittivity is determined for each identified mineral. A volumetric mixing law is employed using the determined mineralogy composition and the determined dry permitivities. An effective matrix permittivity is determined using results from the volumetric mixing law. Dielectric dispersion measurements of the subject formation are acquired using the core samples or the downhole measurements. A dielectric petrophysical model is produced using the dielectric dispersion measurements and the effective matrix permittivity. A water saturation is estimated based on the dielectric petrophysical model. Nuclear magnetic resonance (NMR) T2 measurements having short echo spacings are acquired. A NMR petrophysical model is generated based on the NMR T2 measurements. A total porosity is determined based on the generated NMR petrophysical model. A total gas-in-place estimate is made using the determined total porosity and the estimated water saturation.

Abstract: An acoustic logging tool is disposed in a wellbore during an acidizing operation. Measurements are made using the acoustic logging tool on a region of a formation penetrated by the wellbore and being subjected to the acidizing operation. An acoustic anisotropic property of the formation is inferred at one or more depths of investigation within the region using the measurements, and a wormhole porosity and/or an orientation of one or more wormholes resulting from the acidizing operation is determined. Acidizing operation management decisions may be made based on the determined wormhole porosity and/or orientations of the wormholes. An acidizing operation management decision may be to maintain, increase, or decrease an acid injection rate. Measurements made may include the velocity of an acoustic wave propagating through the formation and the acoustic anisotropic properties of fast waves and slow waves. The acoustic anisotropic properties of the formation generally depend on rock stiffness.

Abstract: A scratch tester has at least one cutter that moves simultaneously both rotationally and axially relative to the rock it is cutting. When rotational and axial movements are constant, the cutter generates a helical groove in the rock. In borehole embodiments, the scratch tester is fixed at a desired location using centralizers, and the cutter is provided on a motorized platform/track that translates between the centralizers and rotates around a central axis. The cutter faces outward and extends via a cutter arm to engage and carve a helical groove in the borehole wall. A laboratory scratch tester includes a holder for a solid cylindrical core sample and a motorized translating frame on which a cutter extends. The cutter is directed toward the core sample, and the holder with the core sample is rotated by a motor so that as the cutter translates relative thereto, a helical groove is cut thereinto.

Abstract: Methods and systems are provided for characterizing a subterranean formation that involve the generation of a 3D geological model of the formation. The 3D geological model can be used in conjunction with a fluid-flow simulator to generate a first 3D resistivity distribution. A second 3D resistivity distribution can be generated based on electromagnetic survey data of the formation. The 3D geological model can be updated based on differences between the first and second 3D resistivity distributions. The simulation and subsequent update to the 3D geological model can be repeated until differences between the first and second 3D resistivity distributions satisfy a stopping criterion. Data characterizing properties of the formation can be extracted from the resulting 3D geological model. The operations can be performed in conjunction with time-lapsed EM measurements before and after subjecting the formation to a production process and the extracted data can be analyzed to identify variations (such as fractures) in the formation that result from the production process.

Abstract: A neutron imaging device employs a neutron source including a sealed enclosure, gamma ray detector(s) spaced from the neutron source, and particle detector(s) disposed in the sealed enclosure of the neutron source. The output of the particle detector(s) can be used to obtain a direction of particles generated by the neutron source and corresponding directions of neutrons generated by the neutron source. Such information can be processed to determine locations in the surrounding borehole environment where the secondary gamma rays are generated and determine data representing formation density at such locations. In one aspect, the gamma ray detector(s) of the neutron imaging device can include at least one scintillation crystal with shielding disposed proximate opposite ends of the scintillation crystal. In another aspect, the particle detector(s) of the neutron imaging device can include a resistive anode encoder having a ceramic substrate and resistive glaze.
