Abstract: The current subject matter is related to optimizing resource (e.g., steam) allocation within steam assisted gravity drainage (SAGD) system, and predicting future oil production from production wells of the SAGD system. In some embodiments data characterizing a hypothetical rate of steam injection into injection wells of the SAGD system can be applied within a capacitance resistance model (CRM) to determine an estimated rate of future fluid production, the fluid being a mixture of oil and water. An emulsion viscosity, as well as the estimate rate of future fluid production, can be applied within a Koval fractional flow model to determine an estimate rate of future oil production. In some cases, the hypothetical rate of steam injection can be optimized based on an optimization objective, e.g., a steam-to-oil ratio (SOR).

Abstract: The current subject matter provides a GUI that includes an improved navigation bar for visualizing information related to a data set. The navigation bar can allow a user to navigate through, scroll, and/or selectively visualize, certain data within the data set, while also providing visual representations of values recorded within the data set. In one embodiment, the navigation bar can include multiple sections/segments that can correspond to different groups of subsets of the data set. The subsets can be grouped based on values of a particular property/variable recorded in the data set. Colors of each segment of the navigation bar can correspond to values of the property in each group, thereby providing a user with summarized information about the data set. The navigation bar can eliminate a need for additional discrete graphical objects (e.g., charts, graphs, tables, etc.) that would otherwise be used to provide summarized information to the user.

Abstract: A method of determining the profile of a surface of an object is disclosed that does not require that the video inspection device be at a certain angle relative to the surface when an image of the surface is obtained (e.g., allows non-perpendicular captures of the image 30). The method determines a reference surface and a reference surface line. The reference surface line is then used to determine a surface contour line on the surface of the object. The profile is then determined by determining the distances between the reference surface and the surface contour line.
