Abstract: A method, apparatus, and program product utilize a buffer defined relative to a wellbore trajectory to generate a work zone around a wellbore for use in connection with formation modeling. In some embodiments, for example, a closed curve such as a non-rectangular, polygonal work zone may be defined around a wellbore based upon a buffer that extends generally transverse to the trajectory of a length of a wellbore a predetermined distance. In addition, boundaries may be defined in a work zone to effectively split the work zone into multiple closed curves or polygons in response to user editing, e.g., to create one or more subsurface layers in the work zone. In such instances, points defining a subsurface layer may be shared by adjacent layers such that editing of such points will affect each of the layers sharing such points.

Abstract: A method for transforming a 2D or 3D earth volume geometry into a 1D earth volume geometry includes performing a measurement using the measurement sensor in a wellbore. A layer boundary in the 2D or 3D earth volume geometry that is nearest to the measurement sensor is identified. A vector from the measurement sensor is generated toward the nearest layer boundary. A first intersection is identified between the vector and the nearest layer boundary, and a second intersection is identified between the vector and another layer boundary. Simulated boundaries that extend through the first and second intersections and are perpendicular to the vector are generated. The 1D earth volume geometry that is bounded by the first and second intersections is identified. A property value is extracted from the 2D or 3D earth volume geometry between the first and second intersections. The property value is assigned to the 1D earth geometry.
