Abstract: A computer-implemented green product management system and method are proposed. The system comprises: a database, a restricted-substance management module and a carbon footprint module. The database is configured to store data required by the restricted-substance management module and the carbon footprint module. The restricted-substance management module comprises: a detection module, configured to detect restricted-substance containing condition of a raw material and all contacted auxiliary consumptive materials in a production process of a product, and a determination module, configured to determine, according to a restricted-substance related predetermined criterion, and based on a detection result of the detection module and data in the database, whether the product conforms to the restricted-substance related predetermined criterion.

Abstract: Methods of performing a reaming operation at a wellsite are disclosed. The method involves measuring surface drilling parameters (e.g., surface torque and surface weight on bit) from surface sensors positioned about a rig, measuring downhole drilling parameters (e.g., downhole weight on bit and downhole torque) from downhole sensors positioned about a downhole tool, generating weight on reamer from the measured surface weight on bit and the measured downhole weight on bit, generating frictional torque by detecting from the surface sensors when the drilling tool is in a rotating off bottom state and selecting a portion of the measured surface torque measured during the rotating off bottom state, generating torque on reamer from the frictional torque, the downhole torque parameters, and the surface torque parameters, and detecting reamer performance by monitoring changes in reamer performance metrics (e.g., reamer aggressiveness) including integrated torque on reamer with weight on reamer.
