摘要： A method can include receiving neutron data and density data for a borehole in a geologic formation; determining a migration length value for a layer of the geologic formation based at least in part on the neutron data; forward modeling at least the layer based at least in part on the migration length value and the density data; and outputting, based at least in part on the forward modeling, modeled neutron data for the layer.

摘要： 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.

摘要翻译： 方法，装置和程序产品利用相对于井筒轨迹定义的缓冲器来生成围绕井眼的工作区域，以用于与地层建模相结合。 在一些实施例中，例如，基于大体上横向于预定距离的井筒长度的轨迹的缓冲器，围绕井眼围绕井眼定义闭合曲线，例如非矩形多边形工作区。 此外，可以在工作区域中界定边界，以响应于用户编辑，例如在工作区域中创建一个或多个地下层，将工作区域有效地拆分为多个闭合曲线或多边形。 在这种情况下，定义地下层的点可以由相邻层共享，使得这些点的编辑将影响共享这些点的每个层。
