• Best Practices to Improve Accurate Time Stamping of Data at the Well Site  

    Several companies collect data at the rig, and each company’s data acquisition system applies its own timestamp to the data. Subsequent aggregation of data relies on synchronized timestamps which are rarely true. This paper presentation shares the different sources or errors in data time stamping and provides best practices to help mitigate some of these causes. 

    Timestamping is a more involved matter than synchronizing clocks; it calls for agreement on standards and a degree of metadata transparency. The paper presented describes sender versus receiver time stamping, the downhole to surface time-stamp chain, and the time stamping of derived data.
