Abstract: A system, method, and computer readable medium for calculating well flow rates produced with electrical submersible pumps using measured voltage, current, frequency and pressure data. An efficiency to flow rate ratio is calculated from the voltage, current, and pressure data. The efficiency to flow rate ratio is used to obtain a non-dimensional flow rate. The flow rate through the electrical submersible pump is calculated from the non-dimensional flow rate.

Abstract: Method and system for determining a characteristic of a subsurface formation traversed by a wellbore. A fluid flow rate in the wellbore is established, the flow being associated with fluid movement in one or more layers in the formation. Fluid data is generated from the fluid flow. The fluid flow rate in the wellbore is selectively altered, and fluid data is re-generated pertaining to the altered flow rates. The fluid data is processed to determine desired reservoir parameters and/or characteristics of an identified stratum in the formation. A method identifies inflexion points on a single phase oil only curve plot using the fluid data to determine layer characteristics and flow stability.
