  • Publication number: 20200225381
    Abstract: Methods, systems, devices, and products for well logging. Methods include conveying a logging tool in the borehole on a carrier; obtaining a borehole image over at least one interval of borehole depth from well logging measurements with a downhole imaging instrument; obtaining acoustic information representative of acoustic reflections from a far-field region of the formation; obtaining quantitative borehole fluid information indicative of properties of a formation fluid in a near-field region of the borehole; generating a borehole connectivity fracture model of the formation in dependence upon the borehole image, the quantitative borehole fluid information, and the acoustic information. Methods may include identifying near-field fractures from the borehole image, and/or identifying far-field fractures from the acoustic information.

  • Publication number: 20170322337
    Abstract: An embodiment of an apparatus for estimating properties of an earth formation includes a carrier configured to be deployed in a borehole in the earth formation, a nuclear magnetic resonance (NMR) measurement device including a transmitting assembly configured to emit a pulse sequence into a region of a sedimentary earth formation, a receiving assembly configured to detect NMR signals in response to the pulse sequence, and a processor configured to receive the NMR signals and estimate one or more mechanical properties of the region. The processor is configured to perform calculating a size distribution based on the NMR signals, the size distribution including at least one of a pore size distribution and a grain size distribution in the region, estimating a strength of the region based on the size distribution, and performing one or more aspects of an energy industry operation based on the strength.

  • Publication number: 20170115420
    Abstract: Methods and apparatus for acoustic velocity well logging. Methods may include estimating a property of an earth formation, including estimating a depth-dependent lateral tectonic strain profile for the earth formation by generating a linear-to-linear transformation constrained to map a first value of a shear wave velocity parameter of the formation to an estimated minimum value of lateral tectonic strain in at least one direction corresponding to at least one principal horizontal stress of the formation, and map a second value of the shear wave velocity parameter of the formation to an estimated maximum value of lateral tectonic strain in the at least one direction, wherein the strain values may be estimated using closure pressure. The first value of the shear wave velocity parameter may be a minimum value of shear wave slowness and the second value of the shear wave velocity parameter is a maximum value of shear wave slowness.

  • Publication number: 20140372041
    Abstract: A method for validating earth formation data for input into a geophysical model includes: determining a lithology of the earth formation; receiving measurement data for a plurality of different properties of the earth formation rock; plotting data points for a first property versus a second property in a cross-plot using the received measurement data; plotting an expected correlation between the first property and the second property on the cross-plot for rock of the determined lithology; establishing an acceptance criterion for validating the data points related to the first property and the second property with respect to the expected correlation; determining which of the plotted data points fall within the acceptance criterion to provide validated data points related to the first property and the second property; and inputting the validated data points related to the first property and the second property into the geomechanical model.

  • Patent number: 8387722
    Abstract: Acoustic velocities measured downhole are used to predict a rock strength using results of a regression analysis that include grain size. The grain size can be obtained from drill cuttings or from NMR measurements. The determined rock strength is used in drilling operations.

  • Patent number: 8296114
    Abstract: Systems, program product, and methods are provided which include analyzing the drillability of a subterranean formation and a database of performance characteristics for drilling bits to facilitate bit design optimization and selection for that formation. Using component subterranean formation data, computer models can be generated for the drillability of a target section in terms of physical, mechanical, and micro-structural properties, and for postulated suitable drilling bit performance characteristics based on physical, mechanical, and micro-structural properties of the target section. The drilling bit performance characteristics are then updated by quantifying effects of the drilling system to be employed. Each performance characteristic can be normalized and plotted on its own axis for easy comparison. Next, a candidate drilling bit design is selected from a library of computer models of drilling bit characteristics for a suite of drilling bit designs.
