  • Patent number: 8990053
    Abstract: Wavelet estimation method, particularly advantageous for full wavefield inversion (“FWI”) of seismic data, that makes use of both the primary and multiple reflections in the data. The inventive method uses an FWI algorithm to generate a subsurface model from primary reflections (101) in a shallow layer before first arrival of multiple reflections (101). The model is then used to simulate multiples (102). The wavelet is subsequently modified (104) such that the simulated multiples closely match the true recorded multiples (103). The simulated multiples may then be subtracted from the measured data (105) thereby creating a deeper top layer of data substantially free of multiples, and the method may then be repeated to extend the subsurface model to a greater depth (106).

  • Patent number: 8958989
    Abstract: The apparatus employs the remote field eddy-current (RFEC) inspection technique to electromagnetically measure physical parameters of a metallic pipe. RFEC devices inserted into and displaced along a cylindrical pipes may be used to measure the ratio of pipe thickness to electromagnetic skin-depth and thus allow for the non-invasive detection of flaws or metal loss. Typically these RFEC thickness measurements exhibit a so-called double-indication of flaws, an undesired artifact due to a double-peaked geometrical sensitivity function of the device. The method describes a means by which this double indication artifact may be removed by an appropriate processing of RFEC measurements performed by an apparatus specifically designed for this purpose. The invention is particularly well designed for applications in the oilfield industry.

    Abstract: Prospect assessment and play chance mapping tools are provided. For assessing potential resources, example systems provide dynamically linked chance maps, transformed in real time from geological properties. Input geological maps or other data are dynamically linked to resulting chance maps, so that changes in the input maps automatically update the chance map in real time. Users can generate a custom risk matrix dynamically linking geological maps with chance maps via interface tools, dropping maps directly into the matrix. A transform may programmatically convert the geologic domain to the chance domain. The user can navigate input maps, select areas of interest, and drag-and-drop geologic properties into an uncertainty engine and distribution builder for uncertainty assessment based on geologic reality. A merge tool can programmatically unify multiple geological interpretations of a prospect. The merge tool outputs a single chance of success value for multiple geologic property values at each grid node.

  • Patent number: 8892413
    Abstract: Method for speeding up iterative inversion of seismic data (106) to obtain a subsurface model (102), using local cost function optimization. The frequency spectrum of the updated model at each iteration is controlled to match a known or estimated frequency spectrum for the subsurface region, preferably the average amplitude spectrum of the subsurface P-impedance. The controlling is done either by applying a spectral-shaping filter to the source wavelet (303) and to the data (302) or by applying the filter, which may vary with time, to the gradient of the cost function (403). The source wavelet's amplitude spectrum (before filtering) should satisfy D(f)=fIp(f)W(f), where f is frequency, D(f) is the average amplitude spectrum of the seismic data, and Ip(f) is the average amplitude spectrum for P-impedance in the subsurface region (306,402) or an approximation thereof.

  • Patent number: 8868346
    Abstract: Systems, methods, and devices are provided to determine an accurate neutron-gamma density (NGD) measurement for a broad range of formations, including low-hydrogen-index or low-porosity formations and formations with heavy elements. For example, such an NGD measurement may be obtained by emitting neutrons into a formation such that some of the neutrons inelastically scatter off elements of the formation and generate inelastic gamma rays. The neutrons and inelastic gamma rays that return to the downhole tool may be detected. Some characteristics of certain formations are believed to affect the fast neutron transport of the formations. Thus, if a formation has one or more of such characteristics, a correction may be applied to the count rate of neutrons, the count rate of inelastic gamma rays, or the neutron transport correction function, upon which the neutron-gamma density (NGD) may be determined.

  • Publication number: 20140278112
    Abstract: Testing water contamination around oil or gas wells. To determine a testing zone around an oil or gas well, multiple variables are received by data processing apparatus. The variables include variables associated with an oil or gas well, variables associated with an entity performing hydraulic fracturing in the oil or gas well, and variables associated with inhabitable regions surrounding the oil or gas well, to name a few. The multiple variables are processed by the data processing apparatus. In response to the processing, a zone around the oil or gas well within which to test for contamination due to the hydraulic fracturing in the oil or gas well is determined.

  • Patent number: 8838695
    Abstract: A networked information management system and architecture for managing files and documents pertaining to oil and gas wells and properties. On request by an authenticated user, a client workstation displays geographical information system (GIS) layers, via a web collaboration portal, for a region of the earth at which wells or properties may be located. The wells or properties within the displayed region enable links to documents or files associated with those wells and properties, and by way of which the system user can access the documents and files. Both structured and unstructured data elements can be accessed by the system. A collaboration portal allows for standardized access to the data, and also for simultaneous or collaborative access to the data. Workflow management capability is also implemented.

    Abstract: A system, method and computer-readable medium for a drilling a borehole is disclosed. Errors associated with multi-station survey measurements are obtained and partitioned into a set of estimated errors and a set of considered errors. A post-fit covariance matrix is determined from the estimated errors and includes the effects of the considered errors on the estimated errors. A drilling parameter of a drill string in the borehole may be altered using the determined post-fit covariance matrix.

  • Publication number: 20140244173
    Abstract: A method of monitoring downhole assets includes tracking a location of a downhole asset relative to a first environment. The configuration information for the downhole asset is acquired, where the configuration information comprises a measurement of one or more forces applied to the downhole asset during assembly of the downhole asset in the first environment. A service life of the downhole asset is determined from the configuration information. One or more parameters related to usage of the downhole environment in a second environment are measured. A remainder of the service life of the downhole asset is determined by reducing the service life by an amount proportional to usage of the downhole asset as indicated by the measurement related to usage of the downhole asset. The remaining service life may be used to automatically initiate an order for new parts. A system of monitoring downhole assets is also disclosed.

  • Patent number: 8812236
    Abstract: A method for optimizing drilling fluids by creating a proper particle size analysis and distribution curve of particle sizing within drilling fluid. The particle size distribution curve is maintained with a maximum particle sizing of 6 microns so as to not allow for coarser drilled solids to degrade beyond the point of mechanical separation to prevent a build-up of low gravity solids that can no longer be removed from the drilling fluid during the drilling operation due to their size. An optimal drilling system requires that drilling fluids be modified through the following process to attain the appropriate particle sizing distribution to: make the most efficient use of the drilling operation, reduce the amount to drilling fluids utilized, and reduce formation damage. The method generates corrective actions to modify the drilling fluids or adjust solids control equipment parameters, to obtain a unique particle size distribution throughout the drilling process.
