A tubular connection made during various oil and/or gas operations such as a tripping operation can be identified based on received data such as hookload and/or block position data. A type of tubular connected can also identified by comparing hookload and/or block position data to a tubular specification database. The identification of the tubular connection and/or type of tubular connected can be used to measure a machine sequence, such as a tripping sequence. The measurement of the machine sequence can be used to optimize an operation such as a tripping or drilling operation.
