  • Patent number: 9874648
    Abstract: There is provided a system and method for reservoir connectivity analysis in a 3D earth model. A subsurface region is identified and a baseline reservoir connectivity model is obtained from the subsurface region. Compartments and connections are determined from the baseline reservoir connectivity model using reservoir connectivity analysis, and a set of 3D objects representing the compartments and/or connections is created from the 3D earth model. A mathematical graph structure is created from the 3D objects and reservoir connectivity scenarios are evaluated based on analysis of the mathematical graph structure and 3D objects.

  • Patent number: 9733388
    Abstract: Systems and methods which utilize functional objects in connectivity analysis are shown. Functional objects may be denoted by a geological feature, a user-defined location, a critical point in a connection network, a region within a 3D volume, etc. Each functional object preferably possesses and/or has associated therewith an ability to obtain information such as relevant connection pathways, linked regions of interest, statistical connection information, etc. Such functional objects may have dynamic regions associated therewith, such as to define an area of uncertainty, for facilitating exploring connectivity. Desired connectivity information can be revealed interactively from within a confusing web of connection pathways through use of the functional objects. Through interactive manipulation of functional objects analysis may be refined or revised. Additionally or alternatively, logical operations may be applied with respect to one or more functional objects to extend or reduce the connectivity of interest.

  • Patent number: 9595129
    Abstract: A method is provided for displaying selected portions of a three-dimensional (3D) volumetric data set representing a subsurface formation. At least one two-dimensional (2D) canvas is generated. The 2D canvas corresponds to a plane in the 3D data set. The 2D canvas is shown in a first display window. One or more primitives are created on the 2D canvas. A volumetric region of the 3D volumetric data set corresponding to the one or more primitives is identified. The volumetric region is displayed in a 3D scene. The 3D scene is shown in a second display window.

  • Patent number: 9593558
    Abstract: A system and method for planning a well path is described. An exemplary method comprises defining a proxy constraint volume as a three-dimensional (3D) cellular volume where each cell has at least one value derived from data from a 3D earth model. An initial well path is defined within user defined drilling parameter constraints. The exemplary method comprises defining acceptable constraint parameters to be applied to values derived from an intersection of the initial well path and the proxy constraint volume. If the intersection of the initial well path and the proxy constraint volume is not within the acceptable constraint parameters, the initial well path may be iteratively adjusted to create successive well paths until at least one of the successive well paths is within the acceptable constraint parameters for the values derived from the intersection of the well path and proxy constraint volume.

  • Publication number: 20160003008
    Abstract: A method is presented for well planning. The method includes modeling one or more reservoir segments within a subsurface model. The reservoir segments, which are associated with target reservoirs, are evaluated prior to creating a well plan based on the reservoir segments to provide a fluid flow path from the reservoir targets to the well pad through the reservoir segments. The method enhances the well planning process through the use of these reservoir segments.

  • Patent number: 9026417
    Abstract: Method for reservoir surveillance using a three-dimensional Earth Model (101) to improve and expedite the surveillance at all scales of investigation (field, reservoir, fault compartment, and individual well) and at all time steps (minutes, hours, days, months, years). The new method allows users to rapidly identify anomalous field and well performance (109) and provides capability to investigate root causes of the performance deviation from predicted (110). Animated co-rendered displays (107) of the earth model and actual (104) and simulated (105) production data enable the user to interactively determine model adjustments back at the basic level of the Earth Model, which are then propagated to a geologic model (102) and then to the reservoir simulator (103) to update it (111) in a physically constrained way.

  • Patent number: 8931580
    Abstract: Method for determining one or more optimal well trajectories and a drill center location for hydrocarbon production. A well path and drill center optimization problem (55) is solved in which one constraint is that a well trajectory must intersect a finite size target region (61) in each formation of interest, or in different parts of the same formation. The finite target size provides flexibility for the optimization problem to arrive at a more advantageous solution. Typical well path optimization constraints are also applied, such as anti-collision constraints and surface site constraints (62).
