  • Patent number: 8731889
    Abstract: A method for calibrating fracture networks. The method includes estimating an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus, and fracture height; determining microseismic event envelope and base intensity data using a three-dimensional geomodel including microseismic event data; and determining hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data. The method further includes calibrating the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity, determining a proppant transportation and distribution scenario, and generating a dual porosity reservoir model based on the calibrated HFT fracture intensity and the proppant transportation and distribution scenario.

  • Patent number: 6836270
    Abstract: Discloses a method and design for map based visualization and presentation of geographic features, terrain and property characteristics. A list of terrain attributes or group of properties are listed in one display area and a corresponding map with symbolized and coordinated property is displayed in a second display area. A property of interest is provided with a property box graphic on the map with the property box containing selected characteristics of the property and anchored at the location of the property. A three-dimensional (3-D) property characteristics model is disclosed which provides a visualization of selected property characteristics. The 3-D model supports visual analysis and comparison of a characteristic of a property to its neighboring properties. The 3-D visualization and analysis model may also be used to evaluate the proximity of a property to a natural hazard.

  • Patent number: 6732120
    Abstract: A display to display a visual representation of geographic information in a first portion of a display and text information in tabular format in a second portion of a display. The text information is subdivided into a group table and a member list table. The group table lists named groups in tabular form and members of the groups are listed in the member list table. Tabular information may include attachments which are capable of appearing as overlaid graphical representations on the geographic display. A method of coordinating the display of geographic graphical and tabular information provides hide/show capabilities for attachment graphics responsive to selection of tabular information. A method for modelling and storing geographic data is disclosed providing the steps of dividing the spatial extent defined by geographic data into uniquely identified cells, grouping geographic data by cells, and storing grouped geographic data into a long binary field of a database record in a relational database.
