Title: Identification of annulus materials using formation porosity
Inventor: QINGZHEN GUO
IPC: G01V5/10
Filed: 2016-04-19
Abstract: Methods, systems, and computer program products for identifying annular space materials calculate a near-to-far ("N/F") neutron count ratio from neutron count rates detected by detectors located near to and far from a neutron source, respectively.

Abstract: A module-based method allows for controlled roll-out of module classes for configuring a process plant (10, figure 1). A second version of a module class (52) is generated based on a modification to a first version of the module class, where the module class is associated with one or more module instances (256a, figure 2) that are each associated with a process control element. A roll-out instruction to update an upgraded process control element is executed, where the upgraded process control element is associated with a new module instance based on the second version of the module class. Non-upgraded process control elements remain associated with the previous module instance based on the first version of the module class. Modification to the first version of the module class includes adding one or more inputs to the module class, and the system further accesses one or more inputs to facilitate at least partial control of the upgraded process control element. One or more inputs to the module class are one or more feedback inputs.
