  • Patent number: 10329888
    Abstract: The method and system describes monitoring and modeling the hydraulic fracturing of a reservoir. The microseismic events caused by hydraulic fracturing on a reservoir are captured by sensor arrays. The data captured by the sensor arrays are then analyzed to determine the source radius, and seismic moment tensor of microseismic events caused by the hydraulic fracturing. This information is then combined with a seismic velocity model to arrive at a discrete fracture network showing at least the orientation, source radius, and source mechanism of each microseismic event. This discrete fracture network is then used to determine the stimulated surface area, stimulated volume, and point of diminishing returns for the hydraulic fracturing process. Hydraulic fracturing engineers can use the algorithms to monitor the well and/or determine well completion.

    Abstract: A subsurface hydrocarbon reservoir with wells is simulated by sequential solution of reservoir and well equations to simulate fluid flow inside the reservoir and well production rates. Sequential solution of reservoir and well equations treats wells as specified bottom hole pressure wells. This avoids solving large matrices resulting from the simultaneous solution of the reservoir and well equations which can be computationally very expensive for large number of unknowns and require special sparse matrix solvers. Such sequential solution involves regular reservoir system solvers complemented by a small matrix for the numerical solution of the well bottom hole pressures.

    Abstract: A subsurface hydrocarbon reservoir with wells is simulated by simultaneous solution of reservoir and well equations which simulate flow profiles along a well without requiring an unstructured coefficient matrix for reservoir unknowns. An analytical model of the reservoir is formed using the known or measured bottom hole pressure. Where several layers in an interval in the reservoir are present between vertical flow barriers in the reservoir, and communicate vertically with others, the communicating layers are combined for analytical modeling into a single layer for that interval for simulation purposes. The matrix of equations defining the unknown pressures and saturations of the intervals of combined layers in the reservoir are solved in the computer, and a perforation rate determined for each such interval of combined layers. Rates for the intervals in the reservoir are then combined to determine total well rate.

  • Patent number: 9013956
    Abstract: A beam tomography computer implemented method and system for generating improved seismic images and earth models without dependence on reflector structure is disclosed. Recorded seismic data is transformed into data beams which are compared to forward modeled beams using an earth model having a velocity model to compute raypaths and a seismic image to specify the reflectors. The tomographic updates to the earth model and velocity model are based on misalignments between the data beams and the same beams forward modeled from the velocity model and the seismic image. The updated earth model and seismic image better describe the true propagation of the beams through the earth.

  • Patent number: 9002648
    Abstract: A system and method for use in a downhole tool having distance measurement, feature detection, and primary measurement devices positioned therein are provided. In one example, the method includes recording a first plurality of features and corresponding positions in a first log using the feature detection device and the distance measurement device, respectively. A first feature of the first plurality of features is selected and the position corresponding to the first feature is identified. The feature detection device is aligned relative to the first feature based on the identified position. A first primary measurement is taken using the primary measurement device while the feature detection device is aligned relative to the first feature. The steps of recording, selecting, moving, and taking are repeated to obtain a second primary measurement while the feature detection device is aligned relative to a second feature of a second plurality of features.

  • Publication number: 20150094958
    Abstract: Four or more seismic attributes are integrated or merged into imaging formats and displayed for geological interpretation via extended quantization. Multi-attribute integration and classification improves the ability to identify geologic facies, and reservoir properties such as thickness, fluid type, or fracture intensity and orientation. The extended quantization groups up to eight attributes as a single attribute for geophysical data classification. Data group reduction criteria are provided to reveal common geological targets in the data, while preserving small variations or thin layers often found in hydrocarbon reservoirs. By combining multiple attributes, image quality is enhanced while providing analysts the ability to observe channels that might not be visible in any single attribute.

  • Patent number: 8949030
    Abstract: A method for processing seismic data. The method includes receiving the seismic data acquired by at least two receivers that are disposed at different depths. The method may then time-align the seismic data, collect a portion of the time-aligned seismic data into a gather and sum the collected time-aligned seismic data in the gather. After summing the collected time-aligned seismic data in the gather, the method may widen a spectrum of the summed seismic data and generate an image of subsurface formations in the earth based on the widened spectrum.

  • Publication number: 20150012220
    Abstract: Seismic shear-wave survey systems and methods that employ inclined borehole pairs with directional detonations. If the boreholes have substantially equal inclinations in opposite azimuthal directions, the resulting signal traces can be combined to isolate shear wave energy contributions, thereby offering potentially enhanced resolution and reduced-complexity interpretation. The boreholes may be cased to ensure repeatability for, e.g., monitoring of reservoir fracturing, treatments, and/or drainage. The directional charges may be immersed to improve coupling of seismic energy into the formation.

    Abstract: Disclosed herein are implementations of various technologies for a method for seismic data processing. The method may receive seismic data for a region of interest. The seismic data may be acquired in a seismic survey. The method may determine an exclusion criterion. The exclusion criterion may provide rules for selecting shot points in the acquired seismic data. The method may determine sparse seismic data using statistical sampling based on the exclusion criterion and the acquired seismic data. The method may determine simulated seismic data based on the earth model and shot points corresponding to the sparse seismic data. The method may determine an objective function that represents a mismatch between the sparse seismic data and the simulated seismic data. The method may update the earth model using the objective function.

  • Publication number: 20140372043
    Abstract: Method for reconstructing subsurface profiles for seismic velocity or other geophysical properties from recorded seismic data. In one embodiment, a starting model of seismic velocity is assumed (10). The computational domain is divided into two (or more) subdomains by horizontal planes based on an analysis of velocity model (30), and the allowed maximum grid size for each subdomain is determined (50). Auxiliary perfectly matched layers (PML's) are attached to each planar interface between subdomains (80), e.g. two PML's on each side of the interface between the coarse and fine subdomains. Simulated seismic data are computed using the SG-DO technique (100-230). The simulated seismic data are compared to the recorded seismic data, then the residual is calculated (240) and used to update the model (320). The method may be iterated until the model is suitably converged (260).

  • Patent number: 8902221
    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.
