  • Patent number: 5072404
    Abstract: A method of tracking fluids flowing along a flow path is disclosed. A flow path is initially described corresponding to the flow path geometry which can be subdivided in real time to correspond to actual fluid volumes which are moved through the flow path. A recursive operation is used to account for moved volumes which exceed segment volumes during one tracking time period. An improved definition of a curved flow path segment is also disclosed. The disclosed method also pertains to maintaining a well pressure balanced by compensating for free fall.
